Private Integrated Services Network (PISN)
- Circuit Mode Bearer Services - Inter-Exchange Signalling Procedures
and Protocol (QSIG-BC)
4th edition (December 2001)
This Standard defines the signalling procedures and protocol
for the purpose of circuit-switched Call Control at the Q-reference
point between Private Integrated services Network eXchanges (PINXs)
connected together within a Private Integrated Services Network
The Q reference point is defined in ECMA-133.
This Standard is based upon that described in Recommendation
including the provisions for symmetrical operation described in
annex D of that recommendation.
Service specifications are produced in three stages and according
to the method specified in ETS 300 387. This Standard contains
the stage 3 specification for the Q reference point and satisfies
the requirements identified by the stage 1 and stage 2 specifications
in ECMA-142, ECMA-148
and ISO/IEC 11584 .
This Standard is applicable to PINXs which interconnect to form
