Subnet Trunkin g Issue 3 March 1996 3-1115 Subnet Trunking Feature Availability This feature is available with all Generic 3 releases. Description Provides modification of the d ialed number so an AAR or ARS call can route over trunk groups that terminate in switches with different d ial plans. Subnet Trunking provides digit insertion, deletion, pauses, and/or wait for dial tone in digit outpulsing, as required, to permit calls to route: nTo or through a remote switc h nOver tie trunks to private network switch nOver CO trunks to the serving central office All AAR and ARS calls ultimately reach a point where they can no longer route on a private network. That is, the call reaches a point where another on-network switch is not available for the call. (In an ARS stand-alone configuration, this is the originating switch.) Assuming the c all is not denied at this point, then the c all must route to one of the following: nDirectly to a party at the local switch. nTo a party at a remote switch (without accessing the public network). nThrough a remote switch to a p arty at a subtending location (without accessing the public network). nDirectly to a WATS serving office. nDirectly to a local CO or a FX CO, both of which may or may not provide dial access to a long-distance carrier. (The alternative to dial access is for the central office to automatically p rovide access to a single long-distance carrier of the subscriber’s choice.) nThrough a remote switch to the local or FX CO serving the remote switch. nThrough a remote switch to the WATS office serving the remote switch. nTo an EPSCS, Common CCSA office, or ETN office. Subnet Trunking is not required on calls terminating directly to a party at the local switch. AAR handles these calls. Subnet Trunking is required on calls routing to or through a remote switch, regardless of the call’s destination.
Feature Descriptions 3-1116Issue 3 March 1996 With direct access to a WATS, EPSCS, CCSA, or ETN office, Subnet Trunking is not normally used. The called number on these types of calls is not normally modified. Subnet Trunking is need e d only if the numb er is modified or if the call passes through some intermediate switch, such as a main. Calls accessing a local or FX CO directly from the terminating switch normally require Subnet Trunking only if access to a long-distance c arrier is other than the carrier automatically provided by the CO. In this case, the appropriate dial access code is inserted into the digit string by the system. Aside from the normal cases, Subnet Trunking can be used to provide added functionality to the system, for example, to convert an AAR number into an international numb er. Also, Su bnet Trunking can modify a digit string so that a Remote Access trunk group can be used on calls. This capability is called equivalent DID and may be useful when a location has Remote Access but does not have DID or NID. (NID is the private network equivalent of DID.) Add ition or d eletion of an Area Code on an ARS call does not require Subnet Trunking. ARS handles it via c o de conversion, as required. With AAR, an on-network number can be converted into a public network number. In this case, the conversion may include an Area Code insertion via Subnet Trunking. Any of three special characters may be used with Subnet Trunking: nPause — Delays outp ulsing of subsequent digits for 1.5 seconds. nWait — Can be administered in one of two ways. In the first way, delays outpulsing of subsequent di gits for a preprogrammed interval (from 5 to 25 seconds) or, if tone d etectors are provid e d, until dial tone is received from the d istant switch or the interval expires, whichever occurs first. In the second way, d ial tone must b e received before any outpulsing is d one. nConvert-to-tone — Causes all remaining digits to be outpulsed using tone signaling. Use of these special characters is discussed in the following paragraphs. During outpulsing of a digit string, it may be necessary to pause or wait for the distant switch to act upon the digits already sent. A programmed pause (a ‘‘,’’ symbol) is used when the required action by the d istant switch occurs within 1.5 seconds. Multiple pauses can be used. A ‘‘wait for dial tone’’ character (a ‘‘+’’ symbol) is used to specify a longer interval with the option of sending or dropping after waiting a period of time for dial tone. The ‘‘time to wait’’ is the ‘‘off premises dial tone detect’’ time on the “System Parameters — Features” form. Receipt of dial tone automatically cancels the remainder of an interval when tone detectors are provided. If a dial tone detector is not available on a given call, the system uses the wait interval to d etermine when to resume outpulsing. Multiple waits can be used. If ‘‘outpulse without tone’’ on the “ System Parameters Country
Subnet Trunkin g Issue 3 March 1996 3-1117 O ptions” form is set to no, the trunk is dropped and intercept tone is returned to the calling party. Dial tones will also b e heard if Network Feed b ack During Tone Detect is set to no on the “System Parameters Country Op tions” form. Silence will be heard otherwise. The type of outpulsing, either dial pulse (rotary) or tone, used on a call is specified by the trunk group selected for the call. In some cases, it may be necessary to assure that a p ortion of the digits are sent using tone signaling. The convert-to-tone character (a ‘‘%’’ symbol) is used to indicate that all digits remaining in the string to be outp ulsed will use tone signaling. Digit deletion always b e gins with the first digit. Subnet Trunking can delete up to 11 d i gits and can insert up to 36 digits. The last four d igits dialed are normally retained. Thus, the new digit string can be up to 40 digits long. Typical uses of digit insertion are the conversion of an AAR call to an international call and the insertion, in the US, of a long-distance carrier code, 10xxx, on a domestic call. The insertion of a long-distance carrier access code in the string of digits to be outpulsed does not usually require a pause or wait symbol. Interconnecting offices, other than crossbar offices, can handle the code and the called number as a single string. However, a crossbar office returns dial tone after receiving the long-distance carrier code. Thus, a pause or wait is required between the long-distance carrier code and the called number. Likewise in some countries, access to international trunks returns dial tone after dialing the international access code (for example, 00 in Belgium). Note that the user will not typically hear this dial tone, especially if Network Feedback is set to no on the “System Parameters — Features” form. Considerations Subnet Trunking allows AAR and ARS calls to access the public network. With AAR, the major advantage is that the call continues although no on-network routes are available to handle the call. With ARS, the major advantage is that calls destined for the public network can route partially over the private network, if there is one. This saves toll charges for a portion of the call. It is not necessary to include the trunk access code for the trunk group connecting to the distant switch in the string of d igits to be outpulsed. In fact, such inclusion must be avoided. Access to the interconnecting trunk group is automatic. Outpulsing the access code, therefore, serves no purpose, and will cause mishandling of the call at the d istant end. The wait interval is a System Parameter. This interval can be from 5 to 25 seconds (in increments of one second). Up to four special characters can be included in a string of digits to be outpulsed. Each special character counts as two digits.
Feature Descriptions 3-1118Issue 3 March 1996 Interactions Subnet Trunking is a function associated with the AAR and ARS features. Interactions are the same as those given for AAR and ARS. Administration Subnet Trunking is set by the System Manager as a part of AAR and/or ARS administration. The following items require administration: nWait — Specify the wait interval used with Subnet Trunking. nRouting Pattern — Specify the number of digits to delete (beginning with the first d igit) and the specific string of digits to insert. Special characters, if any, are included in the inserted string. Hardware and Software Requirements Add itional tone detectors such as TN744C-Tone Detector/Call Classifier, TN748C-Tone Detector, TN420C-Tone Detector, or TN2182-Tone Clock/Detector/Generator may be required if the s pecial “wait” character is used frequently. TN420C, TN744C, and TN2182 sup p ort A-law. Private Network Access or ARS software is required for Subnet Trunking.
Switch Based Bulletin Board Issue 3 March 1996 3-1119 Switch Based Bulletin Board Feature Availability This feature requires DEFINITY Communications System G3V3 or later release software. (G3V3 d o es not have to be enabled on the “System-Parameters Customer-Options” form.) High priority messaging requires G3V4 or later release software. Description This feature provides a switch based bulletin board that allows customers and AT&T technical personnel to communicate with each other. A SAT user who has appropriate permissions is able to leave and receive messages on the Switch Based Bulletin Board. In addition, with G3V4 and later release software, AT&T services’ personnel can leave high-priority messages that are displayed on the first ten lines of the bulletin board for easy recognition. This feature is not intended as a substitute for existing escalation procedures b ut as an aid to the existing process. Access to the Switch Based Bulletin Board When the user logs in to the system, they are notified of any messages in the bulletin board and the date of the ‘‘last entered’’ message. If the b ulletin board is at 80% or more c a pacity, an additional message is displayed indicating how full the bulletin b oard is (for examp le, 86%). If a high-priority message exists, the user is also notified at login that a high-priority message exists and when it was entered. In addition, all lo g ged in users receive a message on the SAT prompt line indicating that high-priority messages have been entered on the bulletin b oard, but only after a command has been executed on these SATs. In other words, if the SAT is idle, the message will not ap pear until someone executes a command on that SAT. The users are responsible for maintaining the bulletin board. Users who have ‘‘Ad minister Features’’ p ermissions can enter or change a message except in the first ten lines on the bulletin board. Users who have ‘‘Disp lay Ad min an d Maint Data’’ permissions can display, print, and schedule to print the contents of the bulletin b oard. Users with “init” and “inads” logins can edit the first ten lines of p a ge one of the bulletin board. This area is reserved for high-priority messages.

Bulletin Board Commands
System Commands Used to Access the Switch
Based Bulletin Board
Two c ommands change bulletin board and display bulletin board were added
to access the Switch Based Bulletin Board.
To enter a message into the Switch Based Bulletin Board:
1. Log in to the system with ‘‘Ad minister Features’’ p ermissions.
2. Enter the command change bulletin-board.
3. Enter your message.
4. Commit your message by pressing ‘‘Enter.’’
To display messages in the Switch Based Bulletin Board:
1. Log in to the system with ‘‘Display Admin’’ and ‘‘Maint Data’’ permissions.
2. Enter the command display bulletin board.
Commands Used to Change Switch Based
Bulletin Board Messages
The control keys used for changing existing feature forms are used to change
mess a ges on the Switch Based Bulletin Board. To save changes to the “Bulletin
Board Message” field, execute the save translation command. This also
ensures that messages will not be lost during a reset level 3, 4, or 5.
The following characters are allowed in the “Text” field:
nUppercase and lowerc ase letters, spaces, numerals, and #$%^ &*()_
- + =[]{};’./?@!~|‘\:.
Tab characters are not allowed. If invalid characters are entered in the
“Message” field, a system message is displayed that prompts the user to enter
the correct characters for the “ Message” field.
Entering Messages into the Switch Based
Bulletin Board
After entering the change bulletin board command into the system, the user can
change any message in the “ Message” field with the exception of high-priority
mess a ges. The bulletin board can contain up to three pages of text. The first ten
lines of the first p a ge are reserved for high-priority messages that c an be entered
only b y AT&T service personnel. Each page of the “ Message” field contains up to
20 lines of text with 40 characters per line. Each line of the bulletin board has an
Switch Based Bulletin Board Issue 3 March 1996 3-1121 “Associated Date” field that is populated automatically by the system each time the form is submitted. Displaying Messages on the Switch Based Bulletin Board While entering the display bulletin-board command into the system, the user can request, print, or schedule to print any message on the Switch Based Bulletin Board. Considerations User considerations: nOnly one user can change a bulletin b oard message at a time. nThe user must have the proper permissions to access the bulletin board. nThe user must maintain the information stored in the bulletin b oard and is the responsibility of the user to delete old messages. The user can delete information b y pressing the ‘‘space’’ b ar as the first character in a line, and then pressing the return key. If the bulletin board is full, any new messages overwrite old messages. System considerations: nThe switch must have G3V3 or later software. (G3V3 does not have to b e enabled on the “System-Parameters Customer-Options” form.) nTwo new commands, change bulletin-board and display bulletin-board are ad ded to the system commands. nThe bulletin board provides three pages for each message, each page (except page 1) has 20 lines of text, and each line can have as many as 40 characters. The first line of the first page is reserved for future enhancements. Administration To use the Switch Based Bulletin Board feature, a user must have the correct permissions administered in the “Command Permission Categories” screen. nTo display messages, a user must have the “ Disp lay Admin and Maint Data” field set to yes in the “Command Permission Categories” screen. nTo change messages, a user must have the “ Ad minister Features” field set to yes on the ‘Command Permission Categories’ screen.
Feature Descriptions 3-1122Issue 3 March 1996 Feature Initialization and Recovery Feature recovery from a reset condition: nThe bulletin board does not lose information during a reset level 1 or level 2 and is read in from ta pe during reset levels 3, 4, and 5.
System Measurements Issue 3 March 1996 3-1123 System Measurements Feature Availability This feature is standard with all Generic 3 releases except G3vs/G3s ABP. To receive this feature with G3vs/G3s ABP, you must purchase the System Measurements O ption package or the Basic Call Center O ption Package. NOTE: Security Violations is always provided, even with G3vs/G3s ABP when neither the System Measurements Option p a ckage nor the Basic Call Center Option Package is purchased. Description Provides reports on items such as trunk group usage, hunt group usage and efficiency, attendant group activity and efficiency, and security violations. Individual reports are available for each of the following: nAttendant Groups nAttendant Positions (G3rV1, G3V2, and later releases) nAutomatic Circuit Assurance nBlockage Study (G3rV1, G3V2, and later releases) nCall Rate nCall Summary nCall By Call Trunk Grou p nCoverage Paths nCoverage Principals nDS1 Link Performance Measurements nDS1 Facility Link Performance Measurements (G3rV1, G3V2, and later releases) nHunt Groups nLightly Used Trunks G3vsV1/G3sV1, G3iV1, G3i-Global, G3V2, and later releases) nLoad Balance Study (G3rV1, G3V2, and later releases) nModem Pool Group s nOutage Trunks nPerformance Attendant Group nPerformance Hunt Grou p

None are given automatically. Reports are available on the G3-MT or a remote administration terminal. The reports can be printed if a printer is associated with the terminal. The reports can also b e scheduled to print at the system printer via the Report Scheduler and System Printer feature. Considerations Reports provided by System Measurements contain data that is useful to determine group efficiency. Details of specific items on the reports, as well as guidelines to use the data provided, are given in DEFI NI TY Com munications System Generic 3 Version 4 Traffic Reports , 555-230-511. Traffic measurements are automatically accumulated by the system and are available on demand. However, reports are not archived. If needed, reports must be requested periodically. Obtaining a printed copy can aid in maintaining a history of the system traffic. Detailed information of each call handled by a specific trunk group, if required, must be provided by the CDR feature. Processed CDR data can also provide detailed information on trunk group usage. However, if individual call details are not required for bill-back or cost-allocation, System Measurements should be considered as the means to determine and maintain trunk group efficiency. Interactions None.
