TSC-ADM (Administered Temporary
Signaling Connections)
No alarms are generated for the TSC-ADM (Administered Temporary Signaling
Connections) MO. Due to the unusual length of the full name of this MO (that is,
Administered Temporary Signaling Connections), the abbreviation Administered
TSC is used often in this Maintenance documentation.
In general, administered temporary signaling connections provide a path
through ISDN-PRI switches for supplementary D-channel messages. ISDN-PRI
applications [that is, Distributed Communications System (DCS)] use temporary
signaling connections to exchange user information across an ISDN-PRI
network. What makes Administered Temporary Signaling Connection unique is
that these particular Temporary Signaling Connections stay active for an
extended period time (that is, similar to a permanent data connection). These
ADM Temporary Signaling Connections are used for DCS features that require a
NCATSC, and the ADM TSC serves as the logical channel function in a DCS
network.
A Non-Call Associated Temporary Signaling Connection (NCATSC) is a virtual
connection established within a D-channel. The NCATSC connection provides
user to user service by exchanging USER INFORMATION messages through the
virtual connection in a D-channel without associating any B-channel connections.
An
Administered TSC
is a special NCA Administered TSC defined for the DCS
over the ISDN-PRI D-channel application of G3iV1.1-286 or G3iV2-386. The
Administered TSC connection is a special type of NCATSC that has an
administratively defined endpoint and is established for an extended period of
time.
There are two types of ADMTSCs:
■ Permanent
TSCs are established by the originating PBX (that is
Near-end
ADM TSC)
or by the terminating PBX (that is,
Far-end
ADM TSC). Once these
ADMTSCs are established, they remain active.
