SCP-PCS719-011-01H Overview
PCS-719 List 1A July 10, 2001 1
OVERVIEW
The PG-FlexPlus ™ 23-inch Central Office Terminal (COT) shelf, PCS-719 List 1A, supports a common
management or alarmunit, two multiplexer units and up tosixteen universal or integrated PG-Plus®CentralOffice
Line Units (COLUs) or up to eight PG-FlexPlus Integrated Central Office Line Units (FICOLUs).
DESCRIPTION AND FEATURES
The PCS-719 provides convenient mounting of a PG-Plus Alarm Unit (PAU) or PG-Plus Management Unit
(PMU), PG-Plus Multiplexer Units (PMXs) and COLUs. Termination points for subscriber circuits, alarm, power,
and metallic test access are located on the backplane at the rear of the COT shelf. All circuit boards are installed
from the front of the COT shelf. The PCS-719 COT shelf accommodates the following units (see Figure 1, “Front
View of the PCS-719 COT Shelf,” on page 1):
•16 COLUs or 8 FICOLUs
•Two PMXs
•One PAU or one PMU
Figure 1. FrontViewofthePCS-719COTShelf
The PCS-719 COT shelf features include:
•Mounting brackets for installation into a 23-inch equipment rack
•Wire-wrap connections for High-bit-rate Digital Subscriber Line (HDSL), alarm cutoff, and alarm relays
•Screw terminal connections for frame ground and Central Office (CO) battery
•DB-25 connector for network communications
•BNC connector for inter-shelf communications
•64-pin Telco connector for four-wire service connections
•50-pin Telco connectors for two-wire service connections

COMPOSITE CLOCK SIGNALS
Composite clock signals are a 64 kHz bipolar clock with 8 kHz bipolar violations, that define the bit and byte
boundaries of Digital Data Service (DDS) data as it is transferred within a CO. In support of DDS interfaces,
PG-Plus defines two composite clock interfaces at the PAU/PMU card slot. The PAU/PMU selects the clock and
translates it into bit and byte clocks, which it then distributes to the COLUs. Wire-wrap pins on the backplane
allow the composite clock source to be terminated or daisy-chained to another shelf.
BACKPLANE CONNECTIONS
Each shelf supports the connection of up to sixteen COLUs or eight FICOLUs, two PMX units, and one PAU or
PMU. The backplane of the PCS-719 List 1A contains the connectors shown in Figure 2, “PCS-719 Shelf
Backplane,” on page 2 and Table 1, “PCS-719 Backplane Connectors,” on page 3. Wiring external to the COT
shelf should follow the provisions of the current edition of the National Electrical Code and applicable local codes.
