SCP-PCS718-010-06H Description and Features
PCS-718 List 1 January 6, 2003 1
OVERVIEW
The ADC®PG-Plus®19-inch Central Office Terminal (COT) shelf, PCS-718 List 1, supports a common
management or alarm unit, two multiplexer units and up to twelve universal or integrated PG-Plus Central Office
Line Units (COLUs) or up to six PG-Plus Integrated Central Office Line Units (FICOLUs).
DESCRIPTION AND FEATURES
The PCS-718 provides convenient mounting of a PG-Plus Alarm Unit (PAU) or PG-Plus Management Unit
(PMU), PG-Plus Multiplexer Units (PMXs) and Central Office Line Units (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-718 COT shelf accommodates the
following units (see Figure 1):
•12 COLUs or 6 FICOLUs
•Two PMXs
•One PAU or one PMU
Figure 1. Front View of the PCS-718 COT Shelf
The PCS-718 COT shelf features include:
•Universal mounting brackets for installation into a 19-inch or 23-inch equipment rack
•Wire-wrap connections for 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
•50-pin Telco connector for four-wire service connections
•50-pin Telco connectors for two-wire service connections

Composite Clock Signals SCP-PCS718-010-06H
2 January 6, 2003 PCS-718 List 1
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 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 twelve COLUs or six FICOLUs, two PMX units, and one PAU or
PMU. The backplane of the PCS-718 List 1 contains the connectors shown in Figure 2 and Table 1. Wiring
external to the COT shelf should follow the provisions of the current edition of the National Electrical Code and
applicable local codes.
Figure 2. PCS-718 Shelf Backplane
Information in Tables 2 through 17 can be used for diagnostic and troubleshooting procedures under the
direction of an authorized ADC technical support representative.

PCS-718 List 1 January 6, 2003 3
The following sections identify each connector by type and function.
Power
The COT shelf backplane has a seven-position power terminal strip (TB1) that provides connections for dual
–48 Vdc, common battery return, and frame ground by way of screw terminals. The COT shelf can be wired for
redundant powering, split-powering, or single-source powering depending upon requirements.
HDSL
Each COLU slot is equipped with four wire-wrap pins for xDSL interfaces.
Two-Wire Subscriber Circuits
A total of 72 two-wire subscriber pairs terminate at the Telco connectors (P1, P2,and P3) on the COT shelf
backplane. Six pairs route to each of the twelve COLU slots. See Tables 24 through 26 for the connector pinouts.
Four-Wire Subscriber Circuits
The COT shelf provides a total of twelve four-wire data interfaces that are separate from the two-wire pairs. One
four-wire connection is provided for each of the twelve COLU slots. See Table 27 on page 39 for the connector
pinouts.
COLU Edge Card Connectors
Tables 2 through 13 show the backplane connector pinouts for each COLU slot.
