M/T-ANL (Maintenance/Test Analog Port)
S8700 | 8710 / S8500
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 Transmission Measurement System
in Maintenance Procedures
(03-300192). Figure 96
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.
