Digital down-circuit Connection of a PBX with QSIG
If a down-circuit Ascotel PBX is connected with an up-circuit PBX via digital lines
(T, T2), all the features as per QSIG are available providing the up-circuit system
supports the QSIG protocol (see "ISDN Services Supported by the System",
Page 2.291).
The down-circuit PBX is configured in accordance with the rules for networked
PBXs.
The up-circuit ISDN PBX has a connection to the public network. It can also be an
Ascotel or a third-party product, provided it supports the QSIG protocol.
As a rule the down-circuit PBX is connected with the up-circuit PBX via its own
fixed lines. Depending on the PBX type the interfaces can be basic accesses (T) or
primary rate accesses (T2). Connections on an S external-type interface are also
possible instead of connections on a T interface, providing at least one T interface
is available for synchronization via the ISDN network.
