OVERVIEW
The PG-FlexPlusTM AMU-912 List 1 Management Unit provides the user interface into the Central Office Terminal
(COT) Shelf. The AMU-912 allows you to provision, monitor, and test the CO Line Units and Multiplexers (MUXs)
installed in the shelf.
DESCRIPTION AND FEATURES
The AMU-912 is interconnected through a serial bus to each CO Line Unit and MUX 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 AMU-912 has two independently operating RS-232 serial ports, one on the front panel and another on the shelf
backplane. The AMU-912 has two Ethernet ports (one 10Base-2 and one 10Base-T). The 10Base-T interface allows
the AMU-912 to be connected to the network to allow a user to manage the shelf via a telnet connection or Simple
Network Management Protocol (SNMP) operations. The 10Base-2 interface allows multiple shelves to be connected
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 on the shelf backplane. The AMU-912 provides two
management user interfaces:
• VT-100 screens based user interface
• SNMP/Element Management System (EMS) (Stargazer) user interface
You can provision, monitor, and test the system through any of the above interfaces.
The AMU-912 contains a nonvolatile database that stores provisioning data for all systems and MUX units in the
shelf. It monitors the status of all system and MUX units and provides audible and visual alarms classified as major,
minor, and critical.
SNMP Management Information Base (MIB) is available, if needed. For SNMP support, contact Technical
Support on page 115.

It supports Mechanized Loop Testing (MLT) and 4TEL by providing a subset of the TA-909 resistive signatures. The
AMU-912 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 MUX card.
LOCAL AREA NETWORK INTERFACE
The AMU-912 provides two Ethernet ports:
• one for intershelf communication using a 10Base-2
• one for a user interface using a 10Base-T Ethernet connection in accordance with IEEE standard 802.3
10Base-2
• System uses COAX interconnects terminated with BNC connectors on the backplane of the shelf unit
• Shelves are cascaded in a daisy-chain configuration
• 10Base-2 must be terminated on both ends with 50Ωterminations
• Allows SNMP operations
10Base-T
• Standard RJ-45 Ethernet connectivity
• Allows the user to TELNET into the system
• Allows SNMP operations
TEST ACCESS
The AMU-912 test access function meets the following criteria:
• Audible for IDLC only
• Ringing signal for Universal Digital Loop Carrier (UDLC)
• Drop line can support up to 100 ft. line length
• Decodes the Loop Current Feed (LCF), Loop Current Feed Open (LCFO) and Ringing signaling states

July 19, 2004 SCP-AMU912-010-06H
ADC Telecommunications, Inc. 3
TEST INTERFACE
The system supports MLT, 4TEL, screen initiated drop tests and integrated channel testing.
For MLT and 4TEL, the test unit performs tests specified in section 11.4 of TA-909 for fiber to the loop systems.
Additionally, the test results are provided as DC resistive signatures as shown in Table 1 by the AMU-912 to the
Test Tip and Test Ring terminals on the backplane.
Screen initiated drop testing is supported through the RS-232 Craft Port and TELNET interface. Test results as
reported by the on-board test unit located in the RT are presented as pass/fail on the Craft interface. Test results are
not provided as DC resistive signatures for a screen initiated drop test.

In support of MLT testing on the Universal system, the AMU-912 supplies 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 on page 3 by the AMU-912 to the Test Tip and Test Ring
terminals on the backplane. These resistive signatures are routed to the channel under test tip and ring leads and
finally passed to MLT for interpretation (Figure 2). When the test environment includes IMLT on a Class 5ESS
switch, use of a PCU-796 conditioner unit is required for proper PGTC test result reporting.
In support of MLT testing on the Integrated system, the AMU-912 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 on page 3 by the AMU-912 to the Test Tip and Test Ring terminals on the
backplane.

ALARMS
The AMU-912 communicates with each CO Line Unit and MUX in the shelf to provide a summary of active shelf-
level alarms (Figure 3). The CO Line Unit and MUX units inform the AMU-912 of alarms becoming active and
inactive. A summary of alarms for each unit is maintained on the AMU-912. Active shelf alarms are displayed by the
front panel LEDs and through audible and visual relay contacts. These alarm indications 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 shelf system is located in a bay. The shelf ID relay is activated when any visual alarm
is active in the shelf.
The AMU-912 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 CONFIG — Shelf Options on page 66). 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 AMU-912 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 TR08 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 and
Table 4 on page 8 for proper wiring of customer supported DB-25 alarm cable.
Figure 4. ENV Alarm Input Pinouts
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 AMU-912.
When the AMU-912 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.
CAUTION Connections other than those shown in Figure 4 will damage the AMU-912 and will not be covered
under the warranty.
