All connec- rinrs ber\/lleen the key service unit and the tele- phones are made via a customer-provided main distribution frame. Using modular line cord(s), the CO lines are then connected between the -left side panel and the locally provided RJ-25C (up to two each) or RJ-11C (up to six each) jacks. An external tuner (or equivalent) is re- quired if the Music-On-Hold/Background Music feature is utilized. *Some optional features reduce maximum station capacities (see Optional Features). A functional block diagram of both key ser- vice units is shown in Figure 16. It consists of CO and station interfaces on the main PCB, in- cluding a solid-state, space-division matrix and the central control equipment (SCCU/VCCU). Op- tional interfacing equipment includes additional station connections (SSTU), off-hook call an- nounce (SVCU), remote maintenance (SDTU), off- premises line (HOLB), station message detail record (HSMB/STMU*), lA2 interface (HCNB), auxiliary device interface (HIOB), door phone con- troller (HDCB) and door phone/monitor station, external page amplifier (SEPU), internal music- on-hold source (SMOU), and power failure (SPFU”) PCBs are a!so shov.n. “STRA TA Se only The system is entirely under the control of a single-chip microprocessor, located (along with the system program and data memories) on the VCCU/SCCU PCB (STRATA Vie/Se, respec- tively), which mounts on the VMAU/SMAU, re- spectively. Connections between the station voice lines and the CO lines are via the switching matrix provided on the VMAULSMAU PCB (STRATA We/Se, respectively). The VMAUSMAU also provides a similar matrix for intercom connec- tion, background music, paging connections and the distribution of various system tones (dial, busy, etc.). -9-

Ring detection, hold and dial outpuls- ing for these lines are performed by this board. Depending upon local CO require- ments, each incoming line can be sepa- rately connected and programmed to pro- vide DTMF or rotary-dial outpulsing. c) Tone: Performs a number of miscellane- ous system functions: l Generates system tones. , l Provides the switching matrix for the de- livery of tones for both paging and inter- com connections. SCCUNCCU: All system control functions are performed by the single-chip microprocessor on this printed circuit board. The system pro- gram stored in ROM, RAM for system opera- tions, and the RAM for system data storage are also located on this circuit board. A bat- tery on this board protects system memory should a power failure occur. SCOUNCOU: An optional interface between the SMAWVMAU and one/three additional CO line(s). Depending upon local CO require- ments, the SCOU/VCOU is programmed to -12- FIGURE 18 STRATA Vie KEY SERVICE UNIT (with PCBs) provide DTMF or rotary-dial outpulsing. The SCOU serves one CO line; the VCOU serves up to three CO lines, and both serve up to three off-premises lines. SSTU: An optional interface between the key service unit and stations 18 - 25 (stations 14 - 17 on STRATA Se). Each SSTU PCB serves up to four stations. Two-pair wiring is re- quired for each station; one pair carrying vo- ice and the other pair carrying control data to and from the station. SMOU: An optronal music-on-hold source that provides electronic synthesized music. A choice of two musical tunes are available, se- lected via a switch on this board. The SMOU is connected to the SMAWVMAU via an 8-pin connector. SEPU: An optional 3-watt amplifier for external paging, using a customer-supplied 8-ohm speaker (connected to the SMAWVMAU via a 1 O-pin connector). SVCU: The Off-Hook Call Announce interface that mounts on the main printed circuit board of the key service unit to provide OCA access. One SVCU is required for every eight stations requiring OCA. (Adds two intercom lines if STRATA We.)
/. SDTU: Provides Remote Administration/Main- tenance access via its built-in 300/l 200 baud modem. One SDTU per system is re- quired for Remote Administration/Mainten- ance. STMU: Required for connection to an HSMB to provide SMDR for a STRATA Se key service unit. HPSU 6120/7120: Each system’s required voltages are provided by one of these factory- installed power supplies. The HPSU connects to a standard 3-wire, 117 VAC, 60-Hz, grounded wall outlet, with a permissible AC input voltage range of 90 - 130 VAC. HPFB: An opticnal batter!/ backuo unit that is available for the HPSU 6120 (STRATA Se). With the optional battery backup assembly in- stalled, all functions of the system will con- tinue to operate for approximately two to three hours after a loss of normal electrical power. Calls will not be disconnected during switch-over to or from battery power. HPBU-7: An optional battery backup unit for the HPSU 7120 (STRATA Vie). It is a printed circuit board that mounts inside the power supply housing and is connected to the recom- mended battery pack (which is customer- supplied, consisting of two 12 VDC, main- tenance-free, automobile-type batteries-80 amp/hour maximum rating). With the op- tional battery backup assembly installed, all functions of the system will continue to oper- ate for several hours (the actual time period is in direct ratio to the type and size of bat- teries seiected) after a ioss of normai electri- cal power. Calls will not be disconnected dur- ing switch-over to or from battery power. The HPBU-7 also provides a charge to the battery s pack during normal operations. Option Modules HOLB: An off-premises line module that allows the bridging of a CO line, which appears in the system with a conventional telephone; su- pervision is provided. Each HOLB provides three circuits, all three of which may be di- rected to an answering machine (or similar de- vice) attached to the HUNT connector. HDCB: .An optional module (two per system maximum) connected to the key service unit at station 13 and/or 14 (station 11 and/or 12 -13- STRATA s&de GENERAL DESCRIPTION NOVEMBER 1987 on STRATA Se) that allows up to three (each HDCB) door phone/monitor stations (MDFBs) to ring pre-selected stations. The HDCB has three outputs (A, 6, C), which are modular con- nectors for the three MDFBs. (Outputs B and C on either/both HDCB(s) may be used for the Door Lock and Alarm features, respec- tively.) HOXB: An external module .that serves as an interface between the key service unit and conventional, standard telephones or off- premises extension (OPX) lines. Each HOXB PCB serves two extensions; one HOXB per system. An HOXB will operate with either DTMF or rotary-dial telephones. An auxiliary ring generator/power supply (MRGU) is re- quired for use with the HOXB. HSMB: Serves as an interface between the key service unit and a printer or storage device used for the SMDR feature. The module is equipped with an RS-232C interface and con- nects to the left side panel via one supplied 8-wire modular connectors (one HSMB per system). (Se also requires an STMU PCB.) HCNB: Provides an interface between a lA2 key system and the CO lines appearing therein to a STRATAe system. One HCNB is required for every three lines where dual ap- pearances are desired. Also, A-lead control, lamp signal detection and dial outpulsing are performed by this module (see Figure 19).

STRATA Se/We GENERAL DESCRIPTION NOVEMBER 1987 HIOB: Provides one circuit to interface with ex- ternal devices such as a voice mail port, an- swering machine, standard telephone, mo- dem, etc. Up to eight HlOBs (four on a STRATA Se) may be installed on a system. Each HI06 is connected to a proprietary sta- tion port, reducing station capacity accord- ingly. Station Equipment The principal components of the electronic telephone are: handset, dial pad, speaker, micro- phone, two volume controls, four fixed feature buttons, an m button, and 9 or 19 flexible CO/ feature buttons. LED indicators are provided for all buttons except for m and m. See Fig- ures 10 and 12. The single-line electronic telephone (Figure 9) is equipped with three permanently dedicated buttons (mm=) and an Intercom/CO line button, which is not labeled. The lo-button Busy Lamp Field electronic telephone (Figure 11) with speakerphone pro- vides 10 buttons that can be assigned to control intercom, CO line and feature operation, plus an LED indication of which stations are in use. A 20-button Liquid Crystal Display elec- tronic telephone (Figure 13) with speakerphone may be located at any or all of the stations. The 32-character alphanumeric display provides many capabilities- an accurate clock/calendar in its idle state; and elapsed time, dialed number, calling station and CO line are just a few of the features available. For additional ex- planations of the features listed below, see Liq- uid Crystal Display. 0 Al’phanumeric Messaging l Busy Station Messaging e l Called Station Messaging l Calling Station Messaging l Remote Station Messaging l Busy Lamp Field (BLF) Indication l CO Line Identification l Speed Dial Memo l Timed Reminders All phones are easily converted for wall mounting, feature modular handset cords, are equipped with a second modular connector for headset connection (except the single-line), and are connected to the system via modular line cords. -14- An optional replacement base for the elec- tronic telephone provides a built-in 300/1200 baud modem with automatic answering capabil- ities. It is a Bell Standard, full duplex modem. The optional door phone/monitor station (Figure 6) allows distinctive ringing to pre- selected station(s). When a station dials an indi- vidual door phone, a circuit providing monitoring capabilities on the intercom, is established. This option requires station 13 and/or 14 (station 1 1 and/or 12 in STRATA Se) to be replaced by a door phone control unit (HDCB) and up to six door phone units (MDFBs)-three each HDCB. One door phone/monitor (only station 13C for Vle; 11 C for Se) can be replaced by an alarm control circuit on station 13 HDCB and one by a door lock control circuit on all HDCBs. An external amplified speaker (HESB) may be connected in any one of the following three applications: l Loud Ringing Bell: Allows you to amplify the tone of a paging/ringing signal without using other manufacturers’ equipment. The signal can be amplified on all 6000-series phones, except the single-line electronic tele- phone. Three-pair wiring is required for this application. l Amplified Speaker: Allows you to use the HESB as a paging speaker, reducing the need for other manufacturers’ paging equip: ment. l Talkback Amplified Speaker: Allows you to provide a talkback speaker in areas where a telephone is not needed. For talkback opera- tion, connect the HESB to the door phone unit (MDFB), which is used as a microphone; however, the push-button is inoperative. The HESB is a 6” 3-watt speaker with an amplifier that is built into an attractive speaker box (Figure 8). A +12 VDC power supply (HACU-120), which connects to the back panel via an 8’ cord, is included with each HESB. Installation The key service unit is configured for wall mounting only. All external devices are connected to the key service unit via connectors and terminals on the side panels, as follows: a) CO lines are connected to the key service unit right side panel via separate (one for
each line) single-pair modular cords or a single 3-pair modular cord (STRATA Se); or two 3-pair or six single-pair modular cords (STRATA Vie). b) The station connection points are extended from the key service unit to the main distri- bution frame using 3-pair modular line cords. The individual telephones are connected to the main distribution frame using 3-pair sta- tion cables. c) A screw-terminal barrier strip is mounted on the left-hand side of the key service unit to provide attachment points for the music-on- hold source input, relay service (STRATA Vle only) and external page output. d) Two (only one for STRATA Se) modular con- nectors are also provided on the left side panel for two (only one for STRATA Se) op- tional off-premises line modules (HOLBs). The power supply is mounted inside the key service unit. In STRATA Se a connector is pro- vided on the left side panel for optional system reserve power (HPFB). In STRATA Vle an op- tional battery backup printed circuit board is available for the power supply. Maintenance Faults in the system are repaired by replac- ing any faulty component (printed circuit board, subassembly, telephone, etc.) and returning it to the manufacturer for repair. In addition, remote administration/ maintena-rice allows the system to interface via an SDTU (built-in modem) with a remote loca- tion. This reduces the cost of routine data base changes by eiiminaring the need of a technician to be ?n-site for each software change. 07 FEATURES and OPERATION s General This section contains brief descriptions of the features listed earlier in Tables B and C and some associated operating instructions. For more detailed instructions, see the User Guide or Quick Reference Guide. Standard Features System All C&l Voice Page: Dialing a 2-digit access code permits a station user to page via all idle STRATA Se/We GENERAL DESCRIPTION NOVEMBER 1987 telephone speakers simultaneously. The system can also be programmed to include the External Page feature in an All Call Page. Alternate Point Answer: CO or intercom calls can be answered from any station. Automatic Dialing-System: Allows up to 4C numbers to be stored in the system memory. After selecting an outgoing line, any station user can cause one of the.‘stored numbers to be outpulsed by dialing the proper access code. Automatic Hold Recall: A CO line placed on hold by any station will recall that station af- ter a programmable period of time. A different time period can be selected fo: each station. Automatic Release from Hold: The system au- tomatically releases held CO lines if a discon- nect signal is r,eceived from the Central Of- fice. CO Line Pickup Groups: In STRATA Vle only, using a dial code or the m button, allows CO line pickup from another station. Two Call Pickup Groups can be defined in program- ming and buttons (m and m) can be as- signed to phones for each group. Conference (Multi-CO Line): The system will conference two CO lines and up to three sta- tions. See Amplified Conference. Conference(Multi-Station): Non-amplifiedcon- ferencing is permitted to a maximum of four stations and one CO line. See Amplified Con- ference. CTX/PBX Compatible: System features, such as Toll Restriction and Automatic Dialing, are compatible with CTX/PBX operation. CTX Ringing Repeat: To facilitate the use of special calling/callback features on CO/CTX/ PBX lines, the system will ring the called sta- tion with the same on/off cadence that is re- ceived from the outside line. Delayed Ring,ing: A 12- and/or 24-second ring delay may be programmed for each station to permit alternate answering. The delayed ring is provided for each line selectively by each station. Distinctive Ringing: CO and intercom calls are distinguished by different ringing tones. -15-
STRATA Se/‘& GENERAL DESCRIPTION NOVEMBER 1987 DTMF and Dial Pulse CO Line Compatible: The system will interface with either DTMF or rotary-dial pulse CO lines on a line-by-line basis as determined by system programming. External Page Interface: A 600-ohm connec- tion point is provided for a customer-provided external amplifier/speaker. An SEPU PCB (see External Amplified Speaker and External Page Amplifier) is mounted in the key service unit when a customer-provided external speaker only is used; the output impedance is 8 ohms. This page circuit can be accessed as part of the All Call Voice Page feature. F!exible Intercom Numbering: A station inter- com number can be flexibly programmed up to any 4-digit number. It is, therefore, possible to match a station’s intercom and CTX line ex- tension number. Flexible Key Assignment: Allows each phone to be programmed for the optimum use of its CO or feature buttons. Flexible Line Ringing Assignment: A program- mable ring or no ring option is provided for each line selectively by each station. Forced Account Code: Requires selected sta- tion(s) to dial an account code prior to dialing a number. The account code is recorded with call details on the SMDR report. Group Paging: Special 2-digit access codes (81, 82, 83 or 84) permit voice paging to one of four zones. Zone assignment is via $oft- ware and is totally flexible. Paging is via the speakers of idle telephones. Least Cost Routing: Enables the customer to decide over which trunks outgoing voice and data calls will be routed. This can greatly re- duce the cost of long distance calling. Four classes of LCR can be programmed to give priority routes to .the users who need them. (STRATA Vle only.) Live System Programming: Live system pro- gramming is accomplished without service in- terruption to other station users by placing the system in the special programming mode and inputting data via station 17 (station 13 in STRATA Se). Station 17(13) is the only sta- tion that is “down” during programming. -16- Message Waiting: Any station (including the designated Message Center) can set a Mes- sage Waiting LED at any station with the Mes- sage Waiting LED of that station. The called station cancels the LED by lifting the handset and depressing the m button (not avail- able on single-line electronic telephone). See Flash Button. MF Signal Time (160/80 ms): The standard MF dial signal time is 80 milliseconds, but it may be extended to 160 milliseconds, if re- quired by the Central Office or to activate re- mote equipment. Multiple Simultaneous Handsfree Intercom Paths: Two intercom paths are standard in the systems. Both intercom lines are able to carry handsfree conversations simultane- ously. (STRATA Vle may be increased to four paths optionally.) Music-On-Hold Interface: An interface is in- cluded for a customer-provided music source. CO lines placed on hold will be connected to this source. In addition, this music may also be broadcast from electronic telephone speak- ers and external page when the background music programming options are selected. Night Ringing Answer Code: A night ringing call may be answered from any station via a. dial code. Night Ringing Over External Page: As a prd- grammable option, while the night mode is ac- tive, a system-generated ring tone will be transmitted via the external speaker when- ever any line rings (STRATA We only). Night Transfer: On a programmable optional ba- sis, the system can function with two or three ringing patterns. If three patterns are se- lected, they are designated DAY, DAY 2, and NIGHT. If the two-pattern mode is selected, DAY and NIGHT designations are used. In both cases, the ringing modes are selected with the q button on station 10. Non-blocking Dialing: Dialing is permitted on intercom and all CO lines simultaneously. Outgoing Call Restriction: Any station can be selectively restricted from originating calls on any or all CO lines. However, the station may still receive calls on the restricted line(s).
