OPS-LINE (DS1 Off Premises Station
Line)
An analog Off-Premises Station (OPS) can be connected to the system through a
DS1 link. A TN767 DS1 Interface circuit pack or a TN464 UDS1 Interface circuit
pack can support up to 24 DS1 OPSs. Since the DS1 OPS 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.
The DS1 OPS Line Maintenance provides a strategy to maintain an OPS Line via
a trunk port of the TN767 DS1 Interface circuit pack or the TN464 UDS1 Interface
circuit pack. (Throughout this section, the term DS1 Interface can apply to either
of these circuit packs.) The strategy covers initialization tests, periodic tests,
scheduled tests, system technician-demanded tests, and alarm resolution and
escalation. Two service states are specified in a DS1 OPS 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; or
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, a Channel Division
Multiplexer or D4 Channel Bank), refer to the maintenance documentation from
its vendor for details.
