SATURN IiE EPABX Feature Descriptions SECTION 2.00 SYSTEM FEATURES 2.01 System Overview The SATURN IIE System is a stored-program controlled Elec- tronic Private Automatic Branch Exchange (EPABX), which uses Pulse Code Modulation (PCM)!Time Division switching. The SATURN IIE EPABX System is capable of switching both voice and data. The SATURN IIE System is housed in a light-weight equip- ment cabinet called the Basic Cabinet. In its expanded con- figuration, the SATURN IIE System is housed in a Basic Cabinet plus an Expansion Cabinet. The Equipment Cabi- net(s) contain all functional units of the system. Plug-in printed circuit boards (PCBs) are installed in the cabi- net. These PCBs contain the circuits for common control, switching, and for the peripherals required in system opera- tion. The SATURN IIE EPABX provides from 224 to 480 ports in the basic cabinet. The expanded cabinet (stacked atop the basic cabinet) provides an additional 256 to 512 ports (992 ports maximum). A30808-X5130-A120-l-8918 Issue 1. May 1986 An optional Remote Access Unit board provides two AS-232-C ports for general use and one modem port for remote access. A-single RS-232-C port is provided by the CIOP board in the basic system for system interface. The SATURN IIE EPABX System can be arranged to accom- modate conventional telephones (rotary dialing and dual-tone multifrequency (DTMF) dialing) as well as Siemens Digital Tel- ephones (SDTs). The SATURN IIE EPABX can be equipped with a maximum of I2 attendant consoles or it can be operat- ed without any consoles. One cable pair is required to inter- connect each SDT to the SATURN IIE EPABX switching system. Administrative additions and changes are made by input of simplified instructions in plain English format via a local or remote service terminal. These modifications can be made during system operation without interference to normal call processing. The following paragraphs describe the features that are characteristic for the SATURN IIE EPABX System.
SATURN IIE EPABX Feature Descrtptions A30808-X5130-A120-l-B918 Issue 1, May 1986 2.02 a. General Features Additional Input/Output Devices designed to be non-blocking. This network provides up to 36 CCS (1 Erlang) per port. i. Low Power Consumption The SATURN IIE EPABX is capable of connecting in- put/output devices via three RS-232-C interface 110 ports and one port connected to a modem to allow re- mote access. All I/O ports can include, but are not limit- ed to, local service terminal, Station Message Detail Recording (SMDR), automatic traffic measurement reporting, and on-line maintenance and administrative access. The RAUP contains an internal modem with a dedicated RS-232-C interface which provides a re- mote dial-up maintenance port (line or trunk interface). The SATURN IIE EPABX has been designed to pro- vide maximum efficient use and distribution of power via distributed power supplies. Power consumption de- pends on the system configuration: the total number and combination of lines, trunks, SDTs, attendant con- soles, and any auxiliary equipment. A fully-equipped basic cabinet uses a nominal 800 Watts. A fully- equipped system with basic and expansion cabinets uses a nominal 1600 Watts. b. Brownout Protection j. Memory Support The SATURN IIE EPABX power supply is designed to tolerate frequency deviations of as much as 3 Hz above or below the normal input frequency (60 Hz) and in- put voltage variations from 95 to 130 Vat. C. Convection Cooling If an ac power failure occurs, the optional memory sup- port battery supplies the necessary power to maintain the Random Access Memory (RAM) for a minimum of 3 minutes. When power is restored, the internal bat- tery backup, after 30 minutes of charging, is capable of another 3-minute cycle. The SATURN IIE EPABX, because of its low power con- sumption and efficient equipment layout, does not re- quire the use of forced-cooling fans or similar equipment. The cabinet is designed to make full use of convection cooling of all the equipment while main- taining temperature design limits. However, the system must be located within an ambient environment rang- ing from 4 degrees C to 38 degrees C (40 degrees F to 100 degrees F), and a relative humidity range of 20% t0 aovb. k. Off-Premises, Stations The SATURN IIE EPABX extends the station line cir- cuits to industry-standard telephones located at a site remote (off-premises) to the system. I. Station Class-of-Service d. Digital Pad Switching The SATURN IIE EPABX inserts the proper gain or loss into all connection paths to ensure correct transmis- sion levels. The SATURN IIE EPABX provides a maximum of 32 station classes-of-service. Each class-of-service can be arranged in memory to allow or deny access to any combination of features included in the system. For each station, class-of-service codes are stored in memory. These codes can be changed at any time by using the Customer Memory Updating (CMU) procedures. e. DTMF-to-Dial Pulse Conversion MMF-toDial Pulse Conversion enables MMF stations to complete outgoing central office (CO) calls over dial pulse CO trunks. The SATURN IIE EPABX translates the MMF station-generated signals and converts them to dial pulse digits for transmission to the CO. Table 2.00 lists the features which can be assigned to individual stations through class-of-service codes. m. System Site Identification (ID) f. Dual-Tone Multifrequency System Outpulsing DualTone Multi-frequency (MMF) tones are generat- ed as a SATURN IIE EPABX function on outward-dialed calls over MMF Central Office (CO) trunks. DTMF out- pulsing can be provided, regardless of the station di- aling type (DTMF, digital, or rotary). The SATURN IIE EPABX enables the entry of a specific customer’s site identification into the customer portion of the system memory: site location, site name, site number, and/or similar information. These data can contain up to I6 characters and are printed out, via the terminal, as a heading at the beginning and end of each CMU session. n. Trunk Group Class-of-Service End-to-End DTMF Signaling The SATURN IIE EPABX sends DTMF tones through the public network to the distantbnd. The transmis- sion of DTMF tones is used for a variety of purposes, including computer access, control functions, and in- ward call completion at the distant switching system. h. High Traffic Capacity The SATURN IIE EPABX allows the assignment of a variety of attributes to each trunk group in the system. Data established on a per-trunk-group basis include: applicable toll code restriction lists, restricted station classesof-service, alternate trunk groups for routing purposes, incoming/outgoing control signaling informa- tion, incoming/outgoing call-usage types, attendant console answering priority, Direct Inward Dialing (DID) prefixing/deletion/conversion information, night answer- ing assignments, and assigned trunk group alphanu- meric display characters. The switching network of the SATURN IIE EPABX is : .: 2 ‘.. 2-2 (Rev. 5/l/86)

Uniform Station Distribution Wiring The SATURN IIE EPABX maintains consistent cabling requirements regarding size, type, and number of ca- bling pairs connecting all types of station instruments such as single-line telephones (SLTs) and Siemens Dig- ital Telephones (SDTs). A maximum of one cable pair is required between each instrument and the system. Administration Features Customer Memory Updating The CMU feature allows authorized personnel at a designated service terminal to enter and make changes to customer memory during normal system operation with no interference to current call processing. Customer memory, a portion of the complete system memory, contains the data relating to system configu- ration, including programmable features and options which the customer can select and arrange. Changes to customer memory are made by using plain English terms rather than numeric codes, thereby simplifying data base updates. Remote Customer Memory Updating This feature allows authorized personnel at a service terminal to enter and make changes to customer memory from a central depot or off-premises location. Changes can be made during normal system opera- tion with no interference to current call processing. The service terminal must be equipped with a type 103/113- or 212A-compatible modem of the originate-type. The SATURN IIE EPABX is provided with a compatible mod- em of the answer-type equipped (internally) in the RAUP Access to the SATURN IIE EPABX is gained by dial- ing a preassigned public or private network number. Refer to the feature, “Customer Memory Updating.” Remote Traffic and Feature Usage Measurement Detailed traffic and feature usage measurement infor- mation is obtained from a service terminal that is lo- cated remote to the SATURN IIE EPABX. The service terminal must be equipped with a type 1031113. or 21% compatible modem of the originate-type. The SATURN IIE EPABX is provided with a compati- ble modem of the answer-type equipped (internally) in the RAUP Access to the SATURN IIE EPABX is gained by dialing a preassigned public or private network num- ber. Refer to the feature, “Traffic and Feature Usage Measurement.” Station Message Detail Recording (SMDR) The Station Message Detail Recording feature provides a detailed record of all completed incoming and/or out- going trunk calls by trunk group. lntraswitch station- to-station, station-to-attendant, and attendantto-station calls are not-recorded. The following information is recorded: - Access Code Account Code/Authorization Code Authorization Code Index Call Duration Destination Identity Dialed Digits or Called Number LCR Route Selection Number Record Type Source Identity Special Identity Starting Time of Call. The monitored data can be recorded on a suitable printer (via an RS-232-C interface) for hard-copy prin- tout reports. Suitable accounting devices (e.g., SMDR unit) can also be connected to this interface. The SMDR feature allows a service terminal user to enable or disable the following: - SMDR call record output for all incoming and/or outgoing calls over all trunk groups; - SMDR call record output for all incoming calls over a particular trunk group; ‘- SMDR call record output for all outgoing calls over a particular trunk group. Station Message Detail Recording (SMDR) Account Codes Account codes can be used in conjunction with SMDR on incoming and outgoing trunk calls for such pur- poses as cost accounting or client billing. The account codes can be up to 11 numeric digits in length. Two types of account codes are used: (i) standard (or default) account codes and (ii) special account codes. Default account codes are assigned to stations and are automatically activated when a station user originates or receives a call over a trunk. Special account codes must be entered from the user’s telephone after the user has dialed a trunk group access code (e.g., “9” for a CO trunk) or after an LCR access code and desired destinations number. A station user may also override a default account code or previously entered special account code with another special account code at any time during an established trunk call. Recall dial tone is heard when a special account code is required. If a special account code is not entered when requested by the system, the user is restricted from making the call. Only the number of account-code digits is checked by the SATURN IIE EPABX System. Attendant consoles and SDTs can be assigned an ac- count button, thus obviating the need for the user to display and change account codes on a per-call basis. Traffic and Feature Usage Measurement This feature provides the SATURN IIE EPABX with the capability of automatically or manually monitoring and recording various system operations for which traffic and feature usage information is desirable. 2-3
SATURN IIE EPABX Feature Descriptions A30808-X5130-A120-l-8918 Issue 1, May 1986 Two different types of measurements are provided. The first type is event (peg) counts, which give an actual count of the number of times a particular operation has occurred in the system. The second type is usage counts, which give the approximate total time a par- ticular resource is in use during a certain time inter- val. This count is given in CCS (hundred call-seconds). The traffic and feature usage measurement data are stored in system memory. These data can be transmit- ted as output to a service terminal at designated inter- vals (15 minutes to 24 hours, in increments of 1 minute), or on request. Normally, reporting periods are speci- fied in multiples of 15 minutes. For a list of the types of event counts and usage counts that are monitored and recorded in the SATURN IIE EPABX, refer to Table 2.01, “Traffic and Feature Usage Measurement.” g. Variable Timing Parameters This feature provides for authorized personnel to change the timing parameters of system operating functions. The timing parameters are changed by us- ing CMU procedures. 2.04 Flexible Numbering Features a. DID Flexible Station Numbering Direct Inward Dialing (DID) calls from the CO are rout- ed through the SATURN IIE EPABX to the appropriate station. The CO, forwards the last 2, 3, 4, or 5 digits of the directory number as an EPABX station address. The SATURN IIE EPABX can either absorb or prefix the leading digit(s) which are forwarded to it. For example, if the CO forwards 48801 and the station number plan uses numbers 0 through 999, the Saturn IIE EPABX System can delete the 48 so that station 801 is rung. On the other hand, if the CO forwards only 01 and the stations are numbered from 800 through 899, then the number “8” is prefixed by the SATURN IIE EPABX, and station 801 is rung. The SATURN IIE EPABX System can also translate numbers into another range. For example, if the CO forwards the numbers 300 through 399 but the inter- nal station numbering plan starts with 500 (500 through 599), the “3” (the hundreds digit) can be translated to a “5” by the system. This number translation is also provided for the tens digit (in a 2-digit numbering plan) and the thousands digit (in a 4digit numbering plan). With this DID flexible numbering concept, the exter- nal CO numbering plan can be made to agree with the internal station addresses.

Flexible System Numbering Plan The SATURN IIE System allows the assignment of sta- tion numbers, trunk access codes, and feature access codes in accordance with a customer-established num- bering plan. Station numbers and access codes are assigned and/or changed via CMU procedures and can be from 1 to 4 digits in length. Station numbers and access codes of ‘different lengths are allowed provided that an assignment of one number is not a partial dial se- quence of another number. For example, “214” is not allowed in the same system with “2141”. Any first digit, 0 through 9, may be defined as the be- ginning of a station number. However, digit 0 is nor- mally reserved for the attendant. The first digit for access codes may be 0 through 9, l , or #. c. Multiple Listed Directory Numbers The SATURN IIE EPABX System can be supplied with multiple CO- Listed Directory Numbers (LDNs). Each incoming DID trunk group assigned in the system can be provided with an LDN. d. Station Extension Numbering The SATURN IIE EPABX System allows the assignment of an additional number to an existing extension (sta- tion) number. These additional station numbers are known as “alias extension numbers” to the primary (ex- isting) station numbers. 2.05 Night Answering Features a. Assigned Night Answer (ANA) When all attendant consoles are unstaffed, incoming trunk calls normally directed to the attendant are direct- ed to preselected stations. This arrangement is known as Assigned Night Answer (ANA). 2-5
SATURN IIE EPABX Feature Descriptions A30808-X5130-A120-l-8918 Issue 1, May 1986 The night answering station(s) can be an individual sta- tion or the pilot number of a hunt group. The assign- ment of trunks or LDNs to ANA stations (for SATURN IIE Systems served by DID trunks) is performed via a CMU procedure. The night answering stations can make inside and out- side calls and can access system features in the nor- mal manner. When in night service, handling of the incoming trunk calls is accomplished by use of the sta- tion Call Transfer feature. b. Night Service Automatic Switching If an incoming CO call to the attendant console is not answered within a predetermined period of time (vari- able via a CMU procedure), this feature automatically switches the SATURN IIE System into the night serv- ice mode. c. Special Night Answer Position (SNAP) The Special Night Answer Position is either a single EPABX station, the pilot number of a hunt group or an Automatic Call Distribution (ACD) group designated to handle incoming night calls which have not been as- signed to any other night answering mode. The SNAP station can access station-related features in the normal manner. Handling of incoming trunk calls is accomplished by use of the Station Call Transfer fea- ture. SNAP stations are also alerted for night answer Transfer With No Answer or Zoned Universal Night An- swer (ZUNA) No Answer conditions. d. Zoned Universal Night Answer (ZUNA) Arrangements can be made for incoming trunk calls, normally directed to the attendant, to activate a sig- naling device (bells, gongs, etc.) on the customer’s premises when the attendant consoles are unstaffed. This feature is known as Zoned Universal Night An- swer (ZUNA). A maximum of 4 zones, each having an associated sig- naling device, can be provided in the SATURN IIE Sys- tem. Incoming calls to a particular zone can be answered by code. Incoming calls are handled by us- ing the station Call Transfer feature. Sounding of a par- ticular signalling device within a zone is accomplished on a per-trunk basis. DID trunks are handled on a trunk- group basis only. 2.06 System Dialing Features a. Direct Inward Dialing (DID) This feature allows an incoming call from the CO to reach a SATURN IIE EPABX station without using at- tendant assistance. Stations having this feature are as- signed Fdigit telephone numbers within the numbering range of the DID serving CO. b. Direct Inward System Access (DISA) The DISA feature allows an outside party to gain ac- cess to its facilities by dialing directly into the SATURN IIE EPABX, without attendant assistance. To use this feature, the party dials a non-published directory num- ber to connect to the SATURN IIE EPABX via a dedi- cated CO trunk. The user waits for dial tone and then dials a 2- to 6-digit authorization code. After the code has been validated by the system, the party then receives dial tone again and can place a call or use a feature as if the party were at a SATURN IIE EPABX station having the class-of-sewice associated with that authorization code. DISA trunks can be accessed during daytime and nighttime service. DISA trunks may not be used for out- going service as part of another trunk group. The sta- tion class-ofservice can be arranged in SATURN IIE memory to include any combination of call privileges. Two thousand authorization codes (DISA or Mobile) are provided in the system. Each authorization code may be marked as being print- able or not printable for SMDR output. If both an account code and a printable authorization code are used on a particular call, then the associated SMDR call record will only contain the authorization code. If a non-printable authorization code is used, then the authorization code index and the account code (if any) are printed. c. Direct Inward System Access - Shared (DISAS) The DISA - Shared feature is similar in all respects to DISA, except that the trunk group, which is serving this feature, is shared between DISA and normal oper- ation. When the trunk group is marked as DISAS in the SATURN IIE software, calls to the special DISA directory number are handled as incoming calls as long as atJeast one attendant console is in operation. These calls are routed to an attendant. If the system is in the night mode of operation (e.g., no consoles are active), the call is routed via the DI- SAS trunk group, as described in the feature, “Direct Inward System Access.” d. Direct Outward Dialing (DOD) The Direct Outward Dialing feature allows authorized station users to complete outward calls without atten- dant assistance. e. Station-to-Station Calling This feature permits any station user to dial other sta- tions within the SATURN IIE EPABX directly without attendant assistance. Note that station calling restric- tions may prevent stations of one class-of-service from calling stations of another class-of-service. 2.07 System Alarm Features a. Alarm Indication - Major A Major Alarm indicator is provided in the Control Logic Board within the PSU panel. The alarm indicator lights steadily when the system is in a non-operative state and system-failure transfer is active. b. Alarm Indication - Minor A Minor Alarm indicator is provided on the main- tenance panel and lights steadily when the system is 2-6
SATURN IIE EPABX Feature Descriptions A30808-X5130-A120-l-8918 Issue 1, May 1986 operative and has detected a minor alarm condition. A minor alarm can be the result of a system-detected error, either internal or external, a system event of note, such as an annoyance call trace record, or a failure during an on-line diagnostic test. The indicator remains lit until the alarm is displayed by the system adminis- trator via the appropriate CMU procedure. The system administrator can control, via CMU procedure, the set of detectable errors or events that will be reported as minor alarms. A Minor Alarm LED (MIN ALM) is also provided on the attendant console and lights steadily for a selected sub- set (also controllable by the system administrator) of system minor alarms. The indicator remains lit until the alarm is displayed by the system administrator via the CMU procedures, or until the alarm is displayed by the attendant on the attendant console. c. Remote Alarm Identification Dry contact closures are used as the interface for iden- tifying both Major and Minor Alarm conditions exist- ing in the SATURN IIE EPABX. The contacts are located in the Power System Unit (PSU) and can be wired to the Main Distributing Frame (MDF). The con- tact closures can be distributed further, via cable pairs, to a remote location and can be used to activate audi- ble or visual alarms, as needed. d. Power Failure Restart - Floppy Disk This feature is used to reload the system memory from the floppy disks when volatile memory can no longer be maintained during a commercial power failure. When commercial power has been restored, the flop- py disk drives are automatically activated to reload the various elements of system memory. After reloading is completed, the system is capable of full operation. 2.08 Line Lockout Features a. Line Lockout - Attendant Intercept Any station user who remains off-hook without dialing or remains connected to a busy station for more than a predetermined time interval, may be automatically routed to the attendant queue. This feature is provid- ed as an alternative to the normal Line Lockout - Au- tomatic treatment. b. Line Lockout - Automatic This feature helps to to prevent a tie-up of the SATURN’ IIE System’s common equipment, such as DTMF receivers. Whenever a telephone handset is left off- hook, listening to dial tone (without dialing), busy tone, reorder tone, intercept tone, etc., for longer than a predetermined period of time, the system automatically releases the station from the SATURN IIE EPABX switching equipment. When line lockout occurs, the station is disconnected from the system and prevented from making or receiv- ing calls. Placing the telephone handset on-hook or momentarily pressing the hookswitch returns the sta- tion to an operable condition. 2.09 Intercept Features a. Automatic Call Distribution Recorded-Announcement Service The SATURN IIE EPABX is provided with the capabili- ty of connecting an incoming trunk call to a recorded announcement device when all stations in an ACD group are busy. If that particular feature option is provided, an an- nouncement advises the caller of a possible delay (e.g., a “Please hold” message). After the call has been con- nected to the announcement, the SATURN IIE EPABX automatically routes the call to an idle ACD station when one becomes available. Only one recorded-announcement for intercepts is per- mitted per system. b. Flexible Intercept Facilities Calls that cannot be completed because of class-of- service restrictions, unassigned station numbers, or ac- cess codes are routed to an intercept facility. The in- tercept assignment is made via a CMU procedure. For DID and tie trunk calls, the intercept is either to the attendant, a recorded announcement, or to a re- order tone if no recorded announcement is available. For station and attendant calls, the intercept is always to intercept tone. The only exception occurs when a station call is intercepted as the result of an attendant- imposed dial restriction. In that case the call is routed to the attendant. Only one recorded announcement per intercept is permitted per system. 2.10 Access to Customer-Provided Equipment Features a. Code Call Access Station users can dial an access code and a l- to 4-digit called-party code to activate customer-provided code call equipment, which controls signaling devices throughout the premises. The signaling devices can be audible and/or visual. The called party can then an- swer the code call and connect to the calling party by dialing a code call answerback code from any station served by the SATURN IIE EPABX. b. Dictation Access This feature allows station users access to customer- provided dictation equipment in order to record voice messages or play back previously-recorded messages. The dictation equipment is seized by dialing the as- signed dictation access code. Dictation equipment functions such as start, stop, and playback are controlled by dialing the digits assigned for the various functions. A maximum of four dictation channels can be provided in the SATURN IIE EPABX. c. Music On Hold - Line or Trunk Interface The SATURN IIE EPABX is able to interface with customer-provided audio equipment in order to provide
SATURN IIE EPABX Feature Descriptions A30808-X5130-A120-l-6918 issue 1, May 1986 d. Music-On-Hold - Paging This SATURN IIE EPABX System feature allows the customerprovided Music-On-Hold source to be rout- ed to the paging equipment. This arrangement pro- vides music, instead of silence, to the paging zone whenever the paging equipment is idle. e. Music-On-Hold - System The SATURN IIE EPABX is able to interface with customer-provided audio equipment in order to provide music to “held call” conditions. The held call can be the result of Attendant Call Hold, Station Call Hold, Call Park, Manual Hold, and Exclusive Hold Conditions. 2.11 a. Restriction Features Eight-Digit Toll Code Restriction For Direct Trunk Group Access This feature permits SATURN IIE EPABX to allow or deny stations access to specific CO exchanges, area codes, service codes, operator, and other services en- countered on the Direct Distance Dialing (DDD) net- work. The SATURN IIE EPABX can provide 16 separate and different a-digit toll code restriction lists. One or more lists may be assigned to each trunk group. A total of 256 entries may be assigned to the 16 lists. Each entry within a restriction list can be from 1 to 8 digits in length. Each list can be either the “allow” or the “deny” type, and is assigned to stations on a class of-service basis. b. Fifteen-Digit Toll Code Restriction For Direct Trunk Group Access This feature permits SATURN IIE EPABX to allow or deny stations access to specific CO exchanges, area codes, service codes, operator, and other services en- countered on the Direct Distance Dialing (DDD) net- work. The SATURN IIE EPABX can provide 4 separate and different 15-digit toll code restriction lists. One or more lists may be assigned to each trunk group. A total of 32 entries may be assigned to the 4 lists. Each entry within a restriction list can be from 1 to 15 digits in length. Each list can be either the “allow” or the “deny” type, and is assigned to stations on a class-of- service basis. c. Daytime Trunk Control The SATURN IIE EPABX System can be arranged to restrict specific trunk groups from access by stations for outgoing calls during daytime operation, and to re- store access availability when the system is in night service mode. While daytime trunk control is in effect, music to “held-call” conditions. The held call can be the result of Attendant Call Hold, Station Cali Hold, Call Park, Manual Hold, or Exclusive Hold conditions. The Music-On-Hold interface may be assigned as an E&M trunk circuit or as a line circuit (and includes SLMA-S and SLA-16). d. e. 2.12 a. b. c. only the attendant has access to these trunk groups. Station users who attempt calls over trunks under day- time trunk control are routed to the attendant recall queue. Once answered, the call can be completed at the attendant’s discretion. Incoming Class-of Service Blocking This feature prevents an attendant from extending a call if the station’s class-of-service is blocked for the classof-service assigned to the trunk. Station-to-Station Class-of-Service Blocking This feature prevents stations assigned to a certain class-of-service from accessing stations assigned to another class-of-service. An intercept tone is provid- ed to station users dialing stations that are blocked by their class-of-service. Diagnostic and Maintenance Testing Features Automatic On-Line Diagnostic Testing and Reporting The SATURN IIE EPABX is provided with software self- test routines which verify that certain software and hardware operations, initiated by the main controller, have been successfully completed. If an error occurs, software records the error(s) in the “Failure History Memory,” and the minor alarm is activated. Appropri- ate recovery procedures are executed automatically, if necessary. The SATURN IIE EPABX is also provided with a reper- toire of audits that test the SATURN IIE EPABX com- mon control equipment. Each audit performs a specific test and can be individually enabled or disabled by maintenance personnel via the service terminal. When the audit is run, detected failures are recorded in the “Failure History Memory,” and the minor alarm is activated. Appropriate recovery programs are execut- ed automatically on the failing equipment. All audits do not interfere with normal call-processing activities. Manual On-Line Maintenance Testing The SATURN IIE EPABX software package includes test programs that permit test calls to be initiated into and through the system to verify correct operation of the peripheral equipment and selected common equip- ment, such as the tone generator. Resulting visual and audible responses from these tests make it possible to verify correct operation or to detect and isolate a major portion of system malfunc- tions. These test programs are accessed from a main- tenance classmarked telephone. Remote On-Line Maintenance and Diagnostic Testing Maintenance testing can be performed at a location remote from the SATURN IIE EPABX. Access to the Maintenance tests is available on a dial-up basis via local or long-distance trunks by using the DISA facility. Diagnostic testing can also be performed from a re- mote service terminal via dial-up access to the mod- em port on the optional RAUP board.
, SATURN IIE EPABX Feature Descriptions 2.13 Trunking Features a. Alternate Routing The SATURN HE EPABX provides automatic routing of outgoing calls via alternate trunk groups when all circuits in the primary trunk group are busy. A maxi- mum of three alternate trunk groups can be assigned when direct trunk group access is used. Least Cost Routing (LCR) allows up to seven alternates. b. Central Office (City) Trunk Access Access to CO trunks by SATURN IIE EPABX station users is made by dialing an access code. Digit “9” is most-commonly used for such access. c. Common Control Switching Arrangement (CCSA) Access This feature allows station users access to a CCSA net- work by dialing an access code. A network call is placed by dialing the CCSA number of the desired party. Features available to service incoming and out- going calls to and from the CCSA network are similar to those available to incoming and outgoing CO calls. d. Dedicated Incoming Trunks The use of Dedicated Incoming Trunks (DITs) permits a call to bypass the attendant console and ring at a preassigned internal station or hunt group. An unan- swered call can be sent to a night answering arrange- ment (e.g., ANA, UNA, etc.). via the DIT when the following circumstances exist: a) the system is not equipped with a console b) the console is in night service or c) the console is out-of-service. All call-forwarding functions apply to DITs, including the transferring of DIT trunk calls to the attendant when the console is in service. A maximum of 255 DlTs are provided in the SATURN IIE EPABX. e. Enhanced Private Switched Communication Service Access SATURN IIE EPABX station users access an Enhanced Private Switched Communications Service (EPSCS) network by dialing a preassigned access code. By us- ing the EPSCS facility, they may either dial the EPSCS network number of the desired party or an off-network number. Features available to service incoming calls from the network and outgoing calls to the network are similar to the features available to incoming and outgoing CO calls. f. Foreign Exchange Trunk Access An FX trunk is a trunk facility between the EPABX and a CO located beyond the local service area of the sets- ing CO. Such facilities permit the SATURN IIE EPABX System to provide local service to and from the dis- tant service area. Station users gain access to FX trunks by dialing an access code. Issue 1, May 1986 g. Least Cost Routing (LCR) The SATURN IIE EPABX routes outgoing calls over the lowest cost route available at the time of call placement. A station user accesses the LCR feature on a per-call basis by dialing the LCR feature access code before dialing the outside number. The routing of the call is selected from a predefined list of eligible trunk groups based on the digits dialed by the user, the user’s class- of-service, and the time of day. Trunk groups are ranked from first to last choice (i.e., lowest to highest cost), thus providing the lowest cost routing for the existing busy/idle condition of the eligi- ble trunks. The LCR feature provides Outgoing (trunk) Call Queu- ing Callback and Call Queuing - Standby capabilities. To activate the Outgoing Call Queuing - Callback fea- ture, the station user dials the LCR access code and the desired destination number. Assuming all routes are busy, the station user waits for a steady low tone. Upon receiv- ing the steady low tone, the station user places the hand- set on-hook in order to be placed on queue. Once on-queue, the station is called back when a trunk becomes available. The queue is handled on a first- in, first-out basis. One queue per station is allowed at any time. If another attempt is made to invoke a call- back queue on the same station, the previously queued call is removed from the queue and replaced with the latest request. When the Outgoing Call Queuing - Callback feature is .active, the activating station user may receive or originate other calls. The Outgoing Call Queuing Call- back feature can be cancelled at any time via a dialed cancellation code. The LCR Outgoing Call Queuing - Standby feature is an extension of the LCR Callback feature described above. To invoke this feature, the station user waits off- hook in a standby queuing mode and listens to silence or music (if it is provided). The standby queuing mode eliminates the user going on-hook to be called back when a trunk becomes available. When a trunk does become available, the station is connected to the trunk. The station user may convert from standby queuing to callback queuing by going on-hook. The LCR feature is capable of routing calls over trunks in the public network (i.e., CO, FX, WATS trunks), pri- vate network including Common Control Switching Ar- rangement and tie trunks, as well as over Specialized Common Carriers (SCCs). The LCR feature provides the following additional route selection criteria: 1. LCR User Priority. Each station class-of-service user is assigned priority codes that indicate eligi- ble routes. access is permitted only to those routes assigned a priority code which matches one of the priority codes associated with the user’s COS. 2. Time-of-Day and Day-of-Week. Time bands (e.g., 1 PM through 6 PM, 6 PM through 12 midnight,
SATURN IIE EPABX Feature Descriptions called schedules, are assignable on one-hour boundaries for each hour of the day and each day of the week. A “minutes offset” is provided for each schedule to accommodate rate changes that do not occur on the hour. The selection of a route for a given dialing pat- tern is variable, depending on the current schedule. 3. Alternate Trunk Group Advance. When an all- trunks-busy condition exists, three modes of ad- vancing from first-choice to lesser-choice trunk groups are provided: a) Immediate Advance b) Timer-Controlled Advance c) No Advance (i.e., the call is routed over the first- choice trunk group only). The option of which method to use is stored as a classmark in the station’s class-of-service. Atten- dants are always provided with the Immediate Ad- vance mode. 4. Wide-band tone detectors used in conjunction with flexible outpulsing rules with the SATURN IIE Sys- tem are used to detect special dial tone provided by several Specialized Common Carriers. 5. The SATURN IIE EPABX may be programmed to switch from DTMF, detect dial tone, to dial pulse in order to route calls via LCR through a switched tandem network. The system is capable of “tog- gling” from one mode to another, as required for such operation. 6. In order to speed up cut-through on trunk group calls, the LCR feature can be used to analyze the trunk group call digit strings. 7. The SATURN IIE EPABX provides the option of not providing dial tone after dialing the LCR access code on LCR calls. 8. The SATURN IIE EPABX also provides the option to prohibit confirmation tone from being returned after LCR route-selection is completed. 9. The LCR feature provides a filtered dial tone de- tection option to aliow rejection of busy, reorder, and ringback tones. 10 11. Equal Access to Prime Carrier. The LCR feature is also used to route long-distance calls over all customer selected carriers without dialing a spe- cial access code. For example: The SATURN IIE System user dials 9 + 1 + NAX + NNX + XXXX. If the route list’s outdial rule for the prime carrier is satisfied, the system outdials 1 + NAX + NNX + XXXX; if the route list’s outdial rule for a secondary carrier is satisfied, the system outdials 10XxX + NAX + NNX + XXXX. The LCR feature also provides a means for rechecking a lower-cost route even though the call h. i. j. k. I. A30808-X5130-A120-l-8918 Issue 1, May 1986 -- has advanced to, and is in queue for, a more-costly route. This “look back” queuing capability allows a call to be routed over a previously busy but lower- cost route, if a trunk within that trunk group be- comes available before the more-costly route is used. ._ ;., / Least Cost Routing with Provisions for Specialized Common Carrier The LCR feature is capable of routing calls via an SCC through dial or dedicated access. The SCC’s directo- ry number and authorization code may be stored in SATURN IIE memory for outdialing. Because an SCC can be accessed over local CO trunks (i.e., dial-up ac- cess), the SATURN IIE EPABX provides the capability to turn such access on or off, from an attendant con- sole and/or from a service terminal. Up to three SCCs can be accommodated in the SATURN IIE EPABX. Tandem Trunking The SATURN IIE EPABX can act as a tandem switch, routing incoming calls from one switching system to another, without the need for attendant assistance. The major use of this feature is in association with dial tan- dem tie trunk networks to allow tie trunk connections, and in some cases, to allow incoming tie trunk calls automatic access to the CO trunk for completion of lo- cal CO calls. Tie Trunk Access This feature allows station users dial access to one- way or two-way tie trunk circuits interconnecting the SATURN IIE EPABX with another switching system. The trunks can be furnished with E&M signaling, and configured for automatic or dial repeating operation with or without second dial tone. Two-wire or four-wire type E&M trunks are available. Trunk-to-Trunk Connections This feature allows the attendant to extend an incom- ing trunk call to an outgoing trunk. Connections can be made among CO, Foreign Exchange (FX), Wide Area Telephone Service (WATS), Direct Inward Dialing (DID), and tie trunks. All combinations of these trunks can be connected by the attendant. The only restriction is that the incom- ing call must have been completed through a trunk that provides disconnect supervision (generally ground start trunks or E&M trunks). If disconnect supervision is not provided and the attendant attempts to make the con- nection, a three-minute (variable) timer is started. When the timer times out, the trunk-to-trunk connection is recalled to the attendant. Wide Area Telephone Service Trunk Access This feature allows station users access to WATS by dialing an access code. WATS enables customers to make calls over extensive geographic areas at special billing rates. ‘1 :-: 2-10 (10 pages)
