Local Area Network Interface; 10Base-2; 10Base-T; Test Access - ADC PG-FlexPlus AMU-912 Manual

SCP-AMU912-010-06H
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.

OCAL REA ETWORK
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 50Ω terminations
• Allows SNMP operations

10Base-T

• Standard RJ-45 Ethernet connectivity
• Allows the user to TELNET into the system
• Allows SNMP operations

EST CCESS
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
