HYB-LINE (Hybrid Line)
Hybrid Line is another term for the Multi-Function Analog Telephone (MFAT). The
Hybrid Line set is also known as an SCS (Small Communications System).
Hybrid Line set is also known as an SCS (Small Communications System).
The TN762B Hybrid Line circuit pack supports eight of these multifunction
analog telephone sets. The Hybrid Line sets use three pairs of wires: an analog
voice pair, a transmit/receive pair, and a power pair.

This section describes HYB-LINE (Hybrid Line) maintenance. HYB-LINE
maintenance is closely related to, and sometimes interacts with, HYB-BD (Hybrid
Line circuit pack) maintenance. This interaction should be kept in mind when
troubleshooting Hybrid Line problems.

This section occasionally refers to a station’s service state. These service states
are defined as follows:

Use status station to determine terminal service state. Status is reported as
either out-of-service, in-service, or disconnect. The latter is equivalent to the
ready-for-service state.

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.

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.
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.
