The Maintenance/Test Circuit Pack supports Packet Bus fault detection and bus
reconfiguration for the port network in which it is installed. The circuit pack also
provides Analog Trunk testing, and data loopback testing of DCP Mode 2
endpoints and Digital (ISDN) Trunk Facilities via the TDM bus.

endpoints and Digital (ISDN) Trunk Facilities via the TDM bus.
Port 1 of the Maintenance/Test board is the Analog Test port which provides the
Analog Trunk testing function for Automatic Transmission Measurement System
(ATMS). ATMS is a feature in which calls are made from a device called an
Originating Test Line (OTL) over a specific trunk to a device called a Terminating
Test Line (TTL). The OTL and TTL can then send tones over the trunk under test
and determine the quality of the connection. Ports 2 and 3 are the Digital ports
which provide the Digital (ISDN) Trunk testing functions. Port 4 is the Packet port
which provides the Packet Bus maintenance function.

All ports except the Analog port (port 1) of the Maintenance/Test Board are
automatically administered when the circuit pack is inserted into the system and
they are removed when the circuit pack is unplugged from the system. The
Analog port however, is administered via the station screen with the type "105TL"
for an OTL or a TTL. This port remains administered even after the circuit pack is
physically removed from the system. Care should be taken to remove the OTL or
the TTL before unplugging the circuit pack.
