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 the interworking of services and signalling
protocols deployed in corporate telecommunication networks (CNs). The series uses telecommunication concepts as
developed by ITU-T and conforms to the framework of International Standards on Open Systems Interconnection as
defined by ISO/IEC. It has been produced under ETSI work item DTS/ECMA-00216.
The present document defines the signalling protocol interworking for basic services between a Private Integrated
Services Network (PISN) and a packet-based private telecommunications network based on the Internet Protocol (IP). It
is further assumed that the protocol for the PISN part is that defined for the Q reference point (QSIG) and that the
protocols for the IP-based network are based on ITU-T Recommendation H.323 [9].
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.
The present document is contributed to ISO/IEC JTC1 under the terms of the fast-track procedure, for adoption as an
ISO/IEC International Standard.
The present document has been adopted by the General Assembly of December 2001.

1 Scope
The present document specifies signalling interworking between "QSIG" and "H.323" in support of basic services
within a Corporate telecommunication Network (CN).
"QSIG" is a signalling protocol that operates at the Q reference point between Private Integrated services Network
eXchange (PINX) within a Private Integrated Services Network (PISN). The Q reference point is defined in
ECMA-133 [1]. A PISN provides circuit-switched basic services and supplementary services to its users. QSIG is
specified in other ECMA Standards, in particular ECMA-143 [2] (call control in support of basic services).
"H.323" is a set of signalling protocols for the support of voice or multimedia communication within a packet network,
in particular a packet network that uses the Internet Protocol (IP) as its network layer protocol (IP network). H.323
signalling protocols operate between endpoints in an IP network, either indirectly via one or more gatekeepers, or
directly. An endpoint can be a terminal or a gateway to another network. H.323 is an "umbrella" recommendation
referring to various ITU-T Recommendations, in particular H.225.0 [6] and H.245 [8] (basic communication
capabilities).
The present document specifies signalling interworking for basic services that provide a bidirectional transfer capability
for speech, DTMF, facsimile and modem media between a PISN employing QSIG and a private IP network employing
H.323. The present document specifies requirements for establishing user information (audio) connections between the
PISN and the IP network, but protocols for transmitting audio in the IP network and for signalling in order to establish
and close down audio transmission in the IP network are outside the scope of the present document. Supplementary
services are outside the scope of the present document.
Interworking between QSIG and H.323 permits a call originating at a user of a PISN to terminate at a user of a private
IP network, or a call originating at a user of a private IP network to terminate at a user of a PISN.
Interworking between a PISN employing QSIG and a public IP network employing H.323 is outside the scope of the
present document. However, the functionality specified in the present document is in principle applicable to such a
scenario when deployed in conjunction with other relevant functionality (e.g. number translation, security functions,
etc.).
