PART II. DK16 PRINTED CIRCUIT BOARD

INSTALLATION

4GENERAL

4.01This chapter provides procedures for installa- tion of STRATA DK16 system printed circuit boards (PCBs) into the Base and Expansion units. This includes installation instructions, optional configu- ration information, and wiring and programming considerations for each PCB.

4.02Be sure the power supply has been tested, and the ground has been checked. (See Chapter 5, Section I for the power supply and Chapter 3 for grounding.)

4.03It is recommended to install the Base Unit option PCBs K4RCU and/or KSTU before mount- ing the Base KSU on the wall.

4.04Begin Expansion PCB installation only after completion of Expansion Unit installation (see Chap- ter 5, Section I).

5DK16 PCB INSTALLATION CONSIDERATIONS

5.01The STRATA DK16 Base Unit comes stan- dard with eight digital telephone circuits (ports) and four CO line circuits. The digital circuits are inte- grated into the motherboard, and the CO line cir- cuits are on the KCOU which is attached to the P6 and P7 connectors on the motherboard. The com- mon control unit, like the digital telephone circuits, is built into the motherboard.

5.10DK16 Base Unit PCBs

5.11The Base Unit can support an optional KSTU printed circuit board (PCB) which provides four standard telephone circuits (ports). In addition, a K4RCU PCB can be installed to receive DTMF tones, and detect busy tone for Automatic Busy Redial (ABR) operation.

5.20DK16 Expansion Unit PCBs

5.21The Expansion Unit can support a number of PCBs: it can support a PCOU which provides four

CO line circuits; one or two KCDUs which provide two CO line circuits and four digital telephone circuits (ports); a PDKU which provides eight digital telephone circuits (ports); a PEKU which provides eight electronic telephone circuits (ports); a PESU which provides two standard and four electronic telephone circuits (ports); a PSTU which provides eight standard telephone circuits (ports); and a PIOU or PIOUS which both provide a port for a Station Message Detail Recording (SMDR) device, an interface for remote maintenance, and relay control options.

5.22The DK16 Expansion Unit does not come from the factory with any PCBs installed. Any of the PCBs listed above can fit into any of the unit's four universal slots; however, it is recommended that PCBs that support electronic or digital telephones be installed into Slots 04 and 05, because Slots 06 and 07 cannot support Off-hook Call Announce or Data Interface Units (DIUs).

Recommended PCB slot assignments:

•KCDU — Slot 04 and 05 (2 maximum)

•PDKU, PEKU, PESU, PSTU — Slot 04 (1 maxi- mum, cannot be installed with KCDU.)

•PCOU — Slot 05 (1 maximum, cannot be in- stalled with KCDU.)

•PIOU/PIOUS — Slot 06 (1 maximum)

5.30PCB Option Considerations

5.31PCBs may be configured for a variety of hardware and software options. Hardware options are defined as either internal (generally related to optional PCB subassemblies) or external (related to connection of peripheral equipment such as background music, voice mail, etc). Hardware and software options for each PCB are identified in the individual PCB installation procedures in this chap- ter.

5.32PCB Hardware Options. Each PCB must be configured for the applicable hardware options prior to installation of the PCB. Configuration in- structions for internal hardware options are pro- vided in the individual PCB installation procedures in this chapter. Configuration instructions for exter- nal hardware options are provided in Peripheral Installation, Section 100-816-207.
