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

Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Services and Protocols for
Advanced Networks (SPAN).
The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in part 1 [3].
Introduction
This version is based on the 8TD112r2 from SPAN #78 in June 02 and the direct continuation of D8-36 presented at
TC-AT-D in July 02. The main changes are due to the new mechnism for OTID assignment and the additions in the
Subsystem registration. Proposed text changes from Ray Forbes are also covered.

1 Scope
The present document describes the Internet Signalling Transport Protocol (ISTP) to implement Signalling System
No. 7 signalling interconnection to a distributed IPCablecom architecture.
The present document addresses the protocol to implement ETSI SS7 used for signalling interconnection in a
distributed IPCablecom architecture. Specifically, it defines the messages and procedures for transporting SS7 ISUP,
and TCAP messages as defined by ETSI specifications between the IPCablecom control functions (Media Gateway
Controller and Call Management Server) and the SS7 Signalling Gateway. The IPCablecom Networks are always
connected to the PSTN/ISDN using standard ETSI SS7 interfaces Ref (ISUP, MTP and SCCP)
Areas beyond the scope of the present document include:
• address layer management (SNMP), security, and
...
