ADC PG-FlexPlus AMU-912 Manual

This document describes the procedures for turning up a
PCS-719 DLC system chassis mounted in a PG-Flex
Cabinet as an Remote Terminal (RT) or mounted in a CO as
a Central Office Terminal (COT). Refer to Cabinet Module
Installation and Provisioning on page 3 for details.

The PG-Flex Digital Loop Carrier system supports up to 6
Plus
DS0s on a single copper pair or 24 DS0s on two copper pairs.
Services include Plain Old Telephone Service (POTS – Loop
Start/Ground Start [LS/GS] and Universal Voice Grade
[UVG]). CLASS features, MLT testability, and network
management are also supported.
The cabinet can be deployed in either Integrated or
Universal mode. In some cases, no chassis provisioning is
required at the CO. This occurs when a cabinet is deployed
with an Integrated Switch configuration. In other words, the
DS-1 signal comes directly out of a switch port for transport
to the RT cabinet. In Universal Switch applications, the
individual DS0s from the switch are presented to a
PG-Flex system in the CO that multiplexes
Plus
them to a DS-1 signal for transport to the Field
cabinet's PG-Flex system. Be sure you
Plus
understand which application is being used.
Sixteen PLL-735 or 8 FLL-814 line units can be
installed in the cabinet located shelf. High-bit-
rate Digital Subscriber Line (HDSL) circuits
transport these services between the Shelf and the
remote enclosures. All remote enclosures are line
powered from either the PLL-735 or FLL-814
line units.
Subscriber services to the cabinet are transported
between the Class 5 switch or CO located shelf
over T1 or HDSL transport circuits supporting the
TR-08 framing format. Equipment protection is
provided through the shelf backplane; the
backplane terminates these circuits on both PMX-
744 Multiplex Units.

Provisioning Guide
The AMU-912 Management Unit provides shelf
Field management, performance monitoring, alarm, and test
Plus
interface functions.
Doublers can be used to extend the range of the 24 channel
systems. Two additional copper pairs are required between
the cabinet located shelf and remote enclosure for each
doubler installed.
Versions of the remote enclosures are environmentally
hardened and can be mounted externally or internally at the
subscriber location.
PCS-719 S
HELF
The field cabinet shelf has been pre-wired at the factory.
Detailed wiring and fusing information can be found on the
labels located on the inside of the cabinet door.
-48 Battery
The PCS-719 Shelf has been pre-wired at the factory for
redundant -48 VDC battery powering. Battery wiring for the
Shelf goes directly to the equipment fuse panel located

inside the right door cover on the Valare Power System. The
cabinet must be provided with standard 240 volt AC service.
Alarms
All cabinet and shelf alarms have been pre-wired at the
factory. These alarms, when active, send an alarm signal to
the AMU. The AMU processes the alarm and sends it to the
PMX for transport to the NOC. There are four environmental
alarms associated with the cabinet (Table 1).
Table 1. Environmental Alarms
Alarm Description
Intrusion Open door alarm. Pull door plunger to the
OUT position to retire when performing
maintenance.
Fan Failure One or more fans have failed.
Power Major Two or more rectifiers have failed, low
voltage disconnect contactor has opened,
or battery on discharge.
Power Minor One rectifier has failed, circuit breaker or
fuse has opened, or rectifiers not load
sharing
Subscriber Drop Testing/MLT
Termination
Test results on POTS subscriber drops can be
displayed through a maintenance screen in the
AMU-912 or as three-terminal resistive
signatures on the TSTTIP and TSTRING
terminations on the 25th pair located on the 710
D connector.
The TSTTIP and TSTRING leads will connect to
a metallic by-pass pair to the CO or to an MCU in
an adjacent cabinet, if available. Consult your
work order for proper connections. Table 2
shows the resistive signatures that are presented
to the CO test system for various line conditions.
