4.5.6.3 Down-circuit Connection of a PBX with Cordless
System
A PBX with cordless system can be connected down-circuit from another PBX in
a number of ways. As a rule the up-circuit PBX is a larger system.
Digital down-circuit Connection with QSIG
On systems with digital lines, common features as per QSIG can be used, provided
the up-circuit system supports the QSIG protocol (see also under "Digital down-
circuit Connection of a PBX with QSIG", Page 3.32). This means the correspond-
ing functions of the up-circuit PBX are also available from the cordless system.

The number of possible handsets with Ascotel DECT depends on the system limit.
