ANSI SCTE 24-11:2016 pdf download.IPCablecom 1.0 Part 11: Internet Signaling Transport Protocol (ISTP).
This document addresses the protocol to implement SS7 signaling interconnection in a distributed IPCahlecorn PSTN Gateway architecture. Specifically, it defines the messages and procedures for transporting SS7 ISUP, TCAP, and TUP messages between the IPCahlecom control functions (Media Gateway Controller and Call Management Server) and the SS7 Signaling Gateway.
Areas beyond the scope of the document include:
• Address layer management (SNMP), security, and measurements; these are covered in other IPCablecom documentation.
• Implementation and vendor dependent issues, such as performance, functional distribution, network configuration, etc.
• Details about CMS, MGC, and other media communication applications.
In addition, note that from time to time this document refers to the voice communications capabilities of an IPCablecom network in terms of “IP Telephony.” The legal/regulatory classification of IP-based voice communications provided over cable networks and otherwise, and the legal/regulatory obligations. if any, borne by providers of such voice communications, are not yet fully defined by appropriate legal and regulatory authorities and are beyond the scope of this document. Nothing in this document is addressed to, or intended to affect, those issues. In particular, while this document uses standard terms such as “call,”“call signaling,”“telephony,” etc., it should be recalled that while an lPCablecom network performs activities analogous to these PSTN functions, the manner by which it does so differs considerably from the manner in which they are performed in the PSTN by telecommunications carriers, and that these differences may be significant for legal/regulatory purposes. Moreover, while reference is made here to “IP Telephony,” it should be recognized that this term embraces a number of different technologies and network architecture, each with different potential associated legal/regulatory obligations. No particular legal/regulatory consequences are assumed or implied by the use of this term.
1.3 Requirements and Conventions
Throughout this document, words used to define the significance of particular requirements are capitalized. These words are:
“MUST” This word or the adjective “REQUIRED” means that the item is an absolute requirement of this specification.
“MUST NOT” This phrase means that the item is an absolute prohibition of this specification.
“SHOULD” This word or the adjective “RECOMMENDED” means that there may exist valid reasons in particular circumstances to ignore this item, hut the full implications should be understood and the case carefully weighed before choosing a different course.
“SHOULD NOT” This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or event useful, but the full implications should be understood and the case carefully weighted heibre implementing any behavior described with this label.
“MAY” This word or the adjective “OPTIONAL” means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item.
The legal/regulatory classification of IP-hased voice communications provided over cable networks and otherwise, and the legal/regulatory obligations, if any. borne by providers of such voice communications, are not yet fully defined by appropriate legal and regulatory authorities. Nothing in this specification is addressed to, or intended to affect, those issues. In particular, while this document uses standard terms such as “call,”“call signaling”“telephony,” etc., it will he evident from this document that while an IPCahlecom network performs activities analogous to these PSTN functions, the manner by which it does so differs considerably from the manner in which they are performed in the PSTN by telecommunications carriers. These differences may be significant for legal/regulatory purposes.ANSI SCTE 24-11 pdf download.
