OPS-LINE (DS1 OPS Line)
An analog Off-Premises Station (OPS) can be connected to the s ystem through a
DS1 link. A TN767 DS1 Interface circuit pack sup ports 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 d igital signal of a DS1 por t to the OPS
Line and vice versa. See Figure 3-37 for details.
The DS1OPS Line Maintenance provides a strategy to maintain a n OPS Line via a
port of the DS1 Interface circ uit pack. The strategy co vers initialization tests,
periodic tests, system technician-demand ed tests, and alarm resoluti on and
escalation. Two service states are specified in a DS1OPS Line maintenance.
They are:
out-of-service
in which the line is in a deac tivated state and c annot be
used for either incoming or outgoing calls;
in-service
in which the line is in an
activated state and c an be used for b oth incoming and out going calls. If the DS1
Interface circuit p ack is out-of-service, then all l ines on the DS1 Interface circuit
pack are put into the out-of-servic e state, and a Warning alarm is raised .
For maintenance of the remote DS1 endpoint (for examp le, Channel Division
Multiplexer, D4 Channel Bank), refer to the maintenanc e documentation from its
vendor for details.
