OPS-LINE (DS1 Off Premises Station Line)
An analog Off-Premises Station (OPS) can be connected to the sys tem through a
DS1 link. A TN767 DS1 Interface circuit pack or a TN464 UDS1 Interface circuit
pack can supp ort up to 24 DS1 OPSs. Since the DS1 OPS is an analog telephone
set, a channel multiplexer is nec essary as the remote DS1 endpoint that c onverts
the digital signal of a DS1 po rt 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 circ uit pack or the TN464 UDS1 Interface
circuit pack. (Througho ut this section, the term DS1 Interface can apply to either
of these circuit pac ks.) The strategy covers initialization test s, periodic tests,
scheduled tests, sy stem technician-deman ded 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 deac tivated state and ca nnot be
used for either incoming or outg oing calls; or

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 lin es 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, a Channel Division
Multiplexer or D4 Channel Bank), refer to the maintenanc e documentation from
its vendor for details.
