INSTALLATION-SYSTEM DESCRIPTION SECTION 200-096-202 FEBRUARY 1991 IMPORTANT NOTES: 1. Local ordinances may dictate battery type and installation details. 2. The reserve power batteries must be installed while commercial AC power is applied to the system to allow the power supply reserve relay to operate. If batteries are connected after AC power is lost, the batteries WILL NOT power the system and the system W/L L NOT operate. 4.20 Battery Charger 4.21 To allow full normal system operation during a power failure, the power supply has a built-in, current limiting battery charger that maintains cus- tomer-supplied batteries. Electrical characteris- tics of the battery charger include: l Nominal float voltage: 2.275 volts/cell l Charge current: 0.7 amps maximum l Battery discharge cut-off voltage: 20.5 *O.!?V 5 POWER FAILURE/EMERGENCY TRANSFER UNIT 5.00 The Power Failure/EmergencyTransfer Unit (DPFT) provides an optional means of ensuring uninterrupted telephone operation in the event of a power failure. The DPFT (Figure 2-8) automati- cally connects selected CO lines to standard tele- phone lines in the event of a power failure, while CO LINE TEL LINE POWER FAILURE TRANSFER FIGURE 2-8-POWER FAILURE TRANSFER UNIT (DPFT) permitting normal operation when the system is in service. 5.01 The DPFT is a self-contained module that mounts externally to the system’s KSU, typically near the MDF. Connections to the CO lines, stan- dard telephones and the cabinet are made with two50-pinamphenol-typeconnectorson theDPFT. 5.02 The DPFT consists of eight normally open relays, connecting the telephones to PSTU (Stan- dard Telephone Interface Unit) PCB circuits and the CO lines to PCOU (CO Line Unit) PCB circuits (Figure 2-9). If a power failure occurs, the relays close, connecting the telephones directly to the CO lines. Calls can then be placed from the se- lected standard telephones, over the CO lines, completely bypassing the system. 5.03 When the DPFT is reset after a transfer, existing PFT conversations are protected. Individ- ual circuits are restored only when they become idle. 6 PRINTED CIRCUIT BOARD DESCRIPTIONS 6.00 Twelve types of PCBs are available for use in STRATA DK systems. A maximum of seven PCBs can be installed in DK24, nine in DK56, and fifteen in DK96. 6.01 With the exception of the PCTU and PCTUSl PCBs, PCB size and connector provisions are standardized. All PCBs, including the PCTU/ PCTUSl, measure 7.5 x 5.5 in (190 x 140 mm). The PCBs connect to the KSU’s backplane with identical 40-pin male connectors. Except for the PCTU/PCTUSl PCBs, the connectors are posi- tioned in the same location on each board type. 6.02 PCB external connections are made to the Main Distribution Frame (MDF) using the following industry-standard connectors: l 25-pair Amphenol Female: Twenty-five-pair amphenol connectors connect electronic tele- phones, standard telephones and most periph- erals.

Both 4-circuit (CRCU-4) and 8-circuit (CRCU-8) units are available, de- pending on system traffic. The DTMF receivers are shared by users; they are seized for dialing, then released for the next call. PIOU (Option Interface Unit): The PIOU provides a circuit interface with peripheral options as shown in Table 2-C. PIOUS (Option Interface Unit): A reduced version of the PIOU, the PIOUS provides a circuit interface with peripheral options as shown in Table 2-C. IMDU (Remote Maintenance Modem Subassem- bly): The IMDU is an optional built-in modem which provides the system with a link to off-site programming and maintenance equipment, such as a personal computer or ASCII terminal. The IMDU has an internal maintenance channel and does not require a dedicated CO line or station port. Data transmission speed can be set at 300 or 1200 BPS full duplex. PEPU (External Page Interface Unit): A reduced ver- sionofthePIOU,thePEPUprovidesacircuitinterface with peripheral options as shown in Table 2-C. PESU (Standard/ElectronicTelephone Interface Unit): This optional PCB provides the system with a combination of two standard and four electronic telephone circuits. The standard tele- phone circuits may also be connected to op- tional hardware peripherals such as voice mail, auto attendant and fax machines. The PESU has a ring generator for the standard telephone circuits which can be set for high- or low-ring voltage. PESU electronic telephone circuits can be configured for off-hook call announce by installing an optional off-hook call announce upgrade unit (EOCU). The PESU supports HDCB and door phone/locks, but not DSS con- soles or music-on-hold separation. PCOU (CO Line Unit): The PCOU provides the system with four loop-start CO lines and a standard, built-in automatic busy redial (ABR) circuit. Each CO line can be programmed for either rotary or dial pulse. In addition, each CO line has a 3 dB pad option switch to control excessive loudness resulting from close prox- imity to the PBX or central office. Each CO line circuit provides built-in gas tubes for limited protection from lightning. PCOU2 (CO Line Unit): The PCOU2 is a direct replacement for the PCOU. Their fit, form, and function are identical; however, for manufactur- ing reasons, the PCOU was phased out in favor of the PCOU2. .
