M/T-ANL (Maintenance/Test Analog Port)

M/T-ANL (Maintenance/Test Analog
Port)
The Maintenance/Test analog port is port number 1 on the TN771D Maintenance/
Test circuit pack. This port is used by the Automatic Transmission Measurement
System (ATMS) as an Originating Test Line (OTL) or Terminating Test Line (TTL)
for test calls over analog trunks. For more details, see “Automatic Trunk
Transmission System” in
Chapter 5, ‘‘Additional Maintenance Procedures’’ .
Figure 8-66 shows a typical ATMS configuration.
M/T-ANL maintenance ensures that the analog trunk’s testing function is
operating correctly. Although an M/T-ANL alarm can reduce service, it will not
block service. To accurately measure the performance and health of analog
trunks, replace an alarmed TN771D when a new circuit pack is available.
