OPS-LINE (DS1 OPS Line)
An analog Off-Premises Station (OPS) can be connected to the system through a
DS1 link. A TN767 DS1 Interface circuit pack supports up to 24 DS1OPSs. Since
the DS1OPS is an analog telephone set, a channel multiplexer is necessary as
the remote DS1 endpoint that converts the digital signal of a DS1 port to the OPS
Line and vice versa. See
Figure 10-77 for details.
The DS1OPS Line Maintenance provides a strategy to maintain an OPS Line via
a port of the DS1 Interface circuit pack. The strategy covers initialization tests,
periodic tests, system technician-demanded tests, and alarm resolution and
escalation. Two service states are specified in a DS1OPS Line maintenance.
They are: out-of-service in which the line is in a deactivated state and cannot be
used for either incoming or outgoing calls; in-service in which the line is in an
activated state and can be used for both incoming and outgoing calls. If the DS1
Interface circuit pack is out-of-service, then all lines on the DS1 Interface circuit
pack are put into the out-of-service state, and a Warning alarm is raised.
For maintenance of the remote DS1 endpoint (for example, Channel Division
Multiplexer, D4 Channel Bank), refer to the maintenance documentation from its
vendor for details.
