Private Integrated Services Network (PISN)
- Inter-Exchange Signalling Protocol - Message Centre Monitoring
and Mailbox Identification Supplementary Services (QSIG-MCM /
This Standard specifies the signalling protocol for the support
of the Message Centre Monitoring supplementary service (SS-MCM)
as well as the Mailbox Identification supplementary service (SS-MID)
at the Q reference point between Private Integrated services Network
eXchanges (PINXs) connected together within a Private Integrated
Services Network (PISN).
The supplementary service MCM enables a Served User to get informed
by a Message Centre about the status and status changes of messages
stored in that Served Users Mailbox.
The supplementary service MID enables a Message Centre to identify
a specific mailbox of a Served User in case the Served User has
more than one mailbox within the Message Centre. In addition SS-MID
enables a Served User to authenticate himself/herself at a specific
mailbox located within the Messages Centre.
The Q reference point is defined in ECMA-133.
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
The signalling protocol for SS-MCM and SS-MID uses certain aspects
of the generic procedures for the control of supplementary services
specified in ECMA-165.
This Standard also specifies additional signalling protocol requirements
for the support of interactions at the Q reference point between
SS-MCM as well as SS-MID and other supplementary services and
