MET-LINE (MET Line)
The TN735 MET Line circuit pack supports four of these sets as shown below.
Each MET set uses three pairs of wires: an analog voice pair, a transmit pair, and
a receive pair. Power is sent over the transmit and receive pairs. The MET Line
circuit pack supports all 10-, 20-, and 30-button sets.
This section describes MET-LINE (MET Line) maintenance. MET-LINE
maintenance is closely related to, and interacts with, MET-BD (MET Line circuit
pack) maintenance. This interaction should be kept in mind when
troubleshooting MET Line problems.
This section occasionally refers to a station’s
service states
. The service states
are defined as follows:
Use the status station command to determine terminal service state. Status is
reported as either out-of-service, in-service, or ‘‘disconnect,’’ which means the
station is in the ready-for-service state.

1. UU is the universal cabinet number (1 for PPN, 2 - 44 for EPNs). C is the carrier designation (A,
B, C, D, or E). SS is the number of the slot in which the circuit pack resides (01 to 21). pp is the
two digit port number (01, 02, ...).

Out-of-Service The port, and thus the station, have been removed from
service. A busyout of a port will cause it to be
out-of-service.
Ready-for-Service The port on the circuit pack has been put into service,
but the voice terminal has not yet established signaling
communications with the port.
In-Service The voice terminal has established signaling
communications with the port, and the system is ready
to process calls to and from that station. A terminal in
the ready-for-service state will progress to the
in-service state if it is functioning normally, but it can
also be forced into the in-service state if it goes
off-hook.
