SIST-TS ETSI/TS 102 255 V1.1.1:2005 is the Slovenian adoption of ETSI TS 102 255 V1.1.1, a Technical Specification for Private Integrated Services Network (PISN) inter-exchange signalling. It specifies the stage 3 protocol at the Q reference point for the Message Centre Monitoring supplementary service (SS-MCM) and the Mailbox Identification supplementary service (SS-MID) between Private Integrated services Network eXchanges (PINXs). In practice, it tells PINX and message-centre implementers how mailbox monitoring, mailbox identification, message updates, timers and protocol states are handled.
What does SIST-TS ETSI/TS 102 255 V1.1.1:2005 specify?
SIST-TS ETSI/TS 102 255 V1.1.1:2005 specifies the signalling protocol for SS-MCM and SS-MID at the Q reference point between PINXs in a PISN. The document is a stage 3 specification, so it focuses on protocol behaviour: messages, states, procedures, timers and interworking.
The scope covers two related services:
- SS-MCM, which informs a Served User about message status and status changes in the Served User’s mailbox.
- SS-MID, which lets a Message Centre identify a specific mailbox for a Served User with more than one mailbox, and lets a Served User authenticate to a specific mailbox.
The document also covers interactions with other supplementary services and ANFs where those interactions affect signalling at the Q reference point. Broader interactions that do not affect that signalling are handled in the relevant stage 1 specifications.
The document is organized into clauses 1 to 7 and four annexes.
| Annex | What it covers |
|---|---|
| Annex A | Normative Protocol Implementation Conformance Statement (PICS) proforma |
| Annex B | Informative example message sequences for SS-MCM and SS-MID |
| Annex C | Informative SDL representations of the procedures |
| Annex D | Informative list of message types |
What are the key requirements of SIST-TS ETSI/TS 102 255 V1.1.1:2005?
SIST-TS ETSI/TS 102 255 V1.1.1:2005 is mainly about how a PINX must encode and exchange SS-MCM and SS-MID information. The most important points are conformance, call-independent signalling, service-specific data coding, mailbox monitoring behaviour, mailbox identification/authentication, and protocol interactions with other services.
Conformance is tied to Annex A - Clause 2 says a PINX conforms by meeting the requirements identified in the PICS proforma. In practice, implementers need to map their supported functions and options to the proforma, and testers use that same checklist to verify the claim.
SS-MCM uses call-independent signalling - Clause 6.5 says SS-MCM APDUs are exchanged over a call-independent signalling connection, and the sender establishes that connection if needed. The same Call Reference is used for the related return result or return error APDU. In practice, this separates mailbox signalling from ordinary call setup and keeps the service usable even when no call is in progress.
SS-MCM supports monitoring by Message Type - Clause 6.1 and clause 6.3.1 describe activation, deactivation and interrogation for different Message Types, plus update functions for message information. For implementers, this means monitoring is not a single on/off feature - it can be controlled per message category.
SS-MCM distinguishes compressed and complete information - Clause 6.3.1 defines message data structures for both compressed and complete presentation styles, and clause 6.5.1 explains how update information may contain new messages, retrieved messages, or both. In practice, the implementation must decide whether to send summary data or detailed address and timestamp data for the mailbox contents.
SS-MCM uses timers T1, T2 and T3 - Clause 6.9 names the parameter values, while clause 6.5 and Annex C show where the timers are started, restarted and stopped. This matters because the protocol has waiting states and timeout handling, so a product must manage retransmission, completion and expiry cleanly.
Mailbox-full indications are part of SS-MCM - Clause 6.5.1.1.6 covers the case where the mailbox reaches full capacity or a defined threshold for one or more Message Types. In practice, the Message Centre informs the Served User PINX so the user interface or mailbox logic can react to storage pressure.
SS-MID identifies and authenticates a mailbox - Clause 7 says SS-MID lets the Message Centre identify a specific mailbox when a Served User has several, and lets the Served User authenticate to a specific mailbox. Clause 7.3.1 defines the operations
mIDMailboxIDandmIDMailboxAuth, with errors such asinvalidMailboxandauthorizationFailed. In practice, this is the service part that links a user to the right mailbox before access or action is allowed.Interactions with other services are explicitly listed - Clauses 6.8 and 7.8 name the supplementary services and ANFs that need protocol interaction handling, including SS-MWI, SS-CLIP, SS-CFU, SS-CT, SS-DND, SS-SMS and others. For a real implementation, this helps avoid protocol conflicts when mailbox services run alongside call handling, mobility or presentation services.
What terms does SIST-TS ETSI/TS 102 255 V1.1.1:2005 define?
- Private Integrated Services Network (PISN) - A private network environment for integrated services, used here as the network context for the signalling protocol.
- Private Integrated services Network eXchange (PINX) - A network exchange inside a PISN; the protocol runs between PINXs at the Q reference point.
- Message Centre (MC) - The entity that stores messages and exchanges monitoring or identification information with the Served User PINX.
- Served User - The user whose mailbox is monitored or identified by the Message Centre.
- Supplementary Service (SS) - A service added to the basic telephony service model, such as SS-MCM, SS-MID or SS-MWI.
- Application Protocol Data Unit (APDU) - The protocol data unit used to carry remote operation information between PINXs.
- Message Waiting Signal (MWS) - The terminal indication that may be set when new messages are waiting in the mailbox.
Who uses SIST-TS ETSI/TS 102 255 V1.1.1:2005?
SIST-TS ETSI/TS 102 255 V1.1.1:2005 is used by people who implement, test, integrate or purchase PISN signalling equipment.
Typical users include:
- PINX and PBX equipment vendors
- voicemail and message-centre implementers
- signalling protocol developers
- interoperability and conformance test engineers
- quality managers checking supported protocol options
- buyers and integrators who need to compare implementation capabilities
- network teams working on private telecommunication systems that interwork with public ISDNs or non-ISDNs
They use the document to build the protocol, complete the PICS, verify message flows, and check how SS-MCM and SS-MID behave alongside other supplementary services.

Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ECMA on behalf of its members and those of the European
Telecommunications Standards Institute (ETSI).
Brief history
The present document is one of a series of ECMA Standards defining services and signalling protocols applicable to
Private Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to
the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. It has been
produced under ETSI work item DTS/ECMA-00230.
The present document specifies the signalling protocol for use at the Q reference point in support of the Message Centre
Monitoring supplementary service as well as the Mailbox Identification supplementary service. The protocol defined in
the present document forms part of the PSS1 protocol (informally known as QSIG).
SS-MCM is based on SS-MWI and includes its entire functionality. The interoperability with SS-MWI is therefore
guaranteed. Compared to SS-MWI, SS-MCM offers an enhanced functionality for monitoring status changes of
messages stored in the Served User's Mailbox as follows:
• individual activation and deactivation for the monitoring of messages of different Message Type(s) within the
Mailbox as well as interrogation of the actual SS-MCM configuration;
• retrieval of information about all messages (i.e. new and retrieved messages) in the mailbox independent of the
Message Status;
• request of detailed updated information about messages stored in the mailbox.
The present document is based upon the practical experience of ECMA member companies and the results of their
active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national
standardization bodies. It represents a pragmatic and widely based consensus.

1 Scope
The present document 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
