SCP-PMU712-020-08H Overview
PMU-712 List 2 March 1, 2004 1
OVERVIEW
The PG-FlexPlus™ PMU-712 List 2 Management Units provide the user interface into the PG-FlexPlus Central
Office Terminal (COT) Shelf. The PMU-712 allows you to provision, monitor, and test the Central Office (CO)
Line Units and Multiplexers (MUXs) installed in the shelf.
DESCRIPTION AND FEATURES
The PMU-712 is interconnected through a serial bus to each CO line unit and PMX unit installed in the shelf. It
provides the means for a user to provision, monitor, and test the units of the shelf (Figure 1).
Figure 1. Typical System Configuration
The PMU-712 has two independently operating RS-232 serial ports, one on the front panel and another on the
shelf’s backplane. The PMU-712 has a 10Base-2 Ethernet port that connects PMUs of multiple shelves together.
This allows all the cascaded shelves to be managed from a single interface point. Up to 24 shelves can be
connected together through the 10Base-2 connector without an Ethernet repeater. The PMU provides two
management user interfaces:
•a VT-100 screens based user interface
•a Telcordia compliant TL1 user interface
You can provision, monitor, and test the PG-FlexPlus through either interface.
The PMU-712 contains a nonvolatile database that stores provisioning data for all PG-FlexPlus systems and PMX
units in the shelf. It monitors the status of other system units, and provides audible and visual alarms classified as
major, minor, and critical.
The PMU-712 generates independent 64 K and 8 K system clock signals from a composite bipolar clock signal
connected through the shelf’s backplane. These clock signals are used by the Digital Data Service (DDS) cards
and are distributed on the backplane. The clock signals are also terminated at the front panel as a 64 K bit and 8
K byte clock.

It provides Mechanized Loop Testing (MLT) and 4TEL by providing a subset of the TA-909 resistive signatures.
The PMU provides a diode signature for the Integrated Digital Loop Carrier (IDLC) bypass pair test and a test
jack for monitoring and testing a VF drop. The VF drop provides metallic access to any subscriber pair connected
to the backplane or any integrated POTS channel by means of the PMX card.
Local Area Network Interface
The PMU-712 provides an Ethernet port for intershelf communication utilizing a 10Base-2 Ethernet connection
in accordance with IEEE standard 802.3.
•System uses COAX interconnects terminated with BNC connectors on the backplanes of the shelf units.
•Shelves are cascaded in a daisy chain configuration.
•10Base-2 must be terminated on both ends with 50Ωterminators.
•Allows the user to connect to the PG-FlexPlus by means of TELNET.
Voice Frequency Drop Line
The PMU-712 VF drop line meets the following criteria:
•It provides an audible and visual ringing signal, both in UDLC and IDLC configuration.
•The drop line can support up to a 100 ft. line length.
•It can decode the Line Current Feed (LCF) and Line Current Feed Open (LCFO) signal states.
Test Interface
The PG-FlexPlus system supports MLT, 4TEL, screen initiated drop tests, and integrated channel testing.
Screen initiated drop testing is supported through the RS-232 Craft Port. The test unit performs tests specified in
section 11.4 of TA-909 for fiber in the loop systems. Test results as reported by the on board test unit located in
the RT are presented as pass/fail on the Craft screen interface. Additionally, the test results are provided as DC
resistive signatures as shown in Table 1 by the PMU to the Test Tip and Test Ring terminals on the backplane.
The signatures on the List 2 are biased to -14 Vdc.

In support of MLT testing on the Universal PG-FlexPlus system, the PMU will supply 1kΩ from Tip to Ground in
lieu of allowing the PGTC to be activated. For either MLT or 4TEL test systems, subscriber drop test results are
provided as TA-909 DC resistive signatures as shown in Table 1, “DC Resistive Signatures,” on page 2 by the
PMU to the Test Tip and Test Ring terminals on the backplane. When the test environment includes IMLT on a
Class 5ESS switch, use of a PCU-796 conditioner unit is required for proper PGTC test results reporting.
In support of MLT testing on the Integrated PG-FlexPlus system, the PMU provides the diode/410Ω bypass
integrity test signature as required by TR-08. Additionally, subscriber drop test results are provided as TA-909
DC resistive signatures as shown in Table 1, “DC Resistive Signatures,” on page 2 by the PMU to the Test Tip
and Test Ring terminals on the backplane.

Composite Clock
The PMU-712 derives certain system timing from a selected Composite Clock (CCLK) source. This derived
CCLK is used for bit synchronization for the optional external digital functionality (for example, DDS) offered
by the PG-FlexPlus. The CCLK circuitry provides the necessary clocks to the shelf backplane. The CCLK is sent
to two drivers, one of which drives the first eight CO line units, and the other the last eight CO line units. Figure 2
shows the CCLK in relation to bit position, and the 64 kHz and 8 kHz clocks.
Figure 2. Composite Clock Relationship
The PMU-712 activates a front panel Light Emitting Diode (LED) when clock synchronization is obtained. This
LED is used for both CCLKs terminated on the PMU-712. If the LED is on then both CCLKs are functional. In
the event that one CCLK is lost, the LED flashes. When both CCLKs are lost, the LED is off.

SCP-PMU712-020-08H Overview
PMU-712 List 2 March 1, 2004 5
ALARMS
The PMU-712 communicates with each PMX and CO line unit in the shelf to provide a summary of active shelf-level
alarms (Figure 3). The CO line unit and PMX units inform the PMU-712 of alarms becoming active and inactive. A
summary of alarms for each unit is maintained on the PMU. Active shelf alarms are displayed by the front panel
LEDs and through audible and visual relay contacts. These are also obtainable through the Craft interface. An ACO is
provided to silence audible alarms. A shelf ID relay is provided to allow shelf fault isolation when more than one
PG-FlexPlus shelf is located in one bay. The shelf ID relay is activated when any visual alarm is active in the shelf.
The PMU-712 can also accept external environmental alarms via the backplane DB-25 connector; however, the
functionality of the DB-25 must be changed to ENV-ALARMS setting rather than the default setting of CRAFT-PORT
(refer to Shelf Options Screen). The DB-25 connector can function as a craft access port or operate as an external alarm
input source.

ALARM TYPES
Any alarm may be set to the following severities:
•Critical - CR
•Major - MJ
•Minor - MN
•Not Alarmed - NA
•Not Reported - NR
EXTERNAL ENVIRONMENTAL ALARM CONTACT ALARM
INPUTS/OUTPUTS
The PMU-712 allows the rear DB-25 connector to be provisioned as either a craft port (RS-232) or environmental
alarm input (Figure 4). When the rear DB-25 is provisioned for environmental alarm inputs, the conductors operate as
dry input contacts. An alarm is considered active when certain pins are pulled to +8 volts. There are a total of four
Environmental Alarms: ENV1, ENV2, ENV3, and ENV4 (Table 2 on page 8). In addition to the Environmental
Alarms being reported through screens, they are also reported through the Derived Data Link (DDL) of the TR-08
Shelf A DS1. There are three shelf alarm relay settings: Standard, Telemetry and Environmental. The system activates
different relays depending on Shelf Option configuration (Table 3 on page 8). Refer to Figure 4 on page 7 and Table 4
on page 8 for proper wiring of customer supported DB-25 alarm cable.
An alarm type set to NA will accumulate history counts and send an SNMP trap message, but
will not activate an alarm LED or alarm relay. However, Current Status will show ACTIVE. An
alarm set to NR will not be reported by the PMU-712.
When the PMU-712 is used in the Field Shelf, the rear craft port interface is not used for alarm
inputs. Rather, the prewired Alarm cable will contain the Alarm inputs and outputs and will
operate as dry contacts.
