ANSI SCTE 173-1-2017 pdf free download – Requirements for Preferential Telecommunications over IPCablecom Networks.
1.oscOPE
The objective of this standard is to provide an initial set of requirements for preferential telecommunications within IPCablecom networks.Aspects of preferential teiecommunicationsinclude provisions for Authentication and Priority(Special Handling). These requirements do notapply to ordinary emergency calls such as people calling police, fire department, ambulance, etc.This standard defines requirements for capabilities which when implemented should help supportemergency telecommunication services. Note:Pre-emption requirements and authorization
requirements are outside the scope of this standard and are considered to be national matters.2.0DEFINITIONS AND ACRONYMS
Assured capabilities – Capabilities providing high confidence or certainty that criticaltelecommunications are available and perform reliably.
Authentication -The act or method used to verify a claimed identity.
Authorization – The act of determining if a particular privilege, such as access to telecommunications resources, can be granted to the presenter of a particular credential.CM – Cable Modem CMS – Call Management Server
Emergency situation – A situation, of serious nature, that develops suddenly and unexpectedly.Extensive immediate important efforts, facilitated by telecommunications,may be required to restore a state of normality to avoid further risk to people or property. Ifthis situation escalates, it may become a crisis and/or disaster.
International emergency situation – An emergency situation, across internationalboundaries, that affects more than one country.
Label – An identifier occurring within or attached to data elements. In the context of preferential telecommunications it is an indication of priority. This identifier can be used asa mapping mechanism between different network priority levels.
MTA -Media Terminal Adapter
Off-Net – Not on an IPCablecom Network.
On-Net – On an IPCablecom Network.
PIN – Personal Identification Number
Policy – Rules (or methods) for allocating telecommunications network resources among types of traffic that may be differentiated by labels.
Preferential – A capability offering advantage over regular capabilities.
Priority treatment capabilities – Capabilities that provide premium access to, and/or use of telecommunications network resources.
PSTN – Public Switched Telephone Network

4.0 ARCHITECTURAL CASES FOR PREFERENTIAL TELECOMMUNICATIONS
OVER IPCABLECOM NETWORKS
These architectural cases are defined in order to provide the different cases that need to be specified.
4.1 IPCablecom to/from PSTN
This case includes calls made from the PSTN (Off-Net) to the IPCablecom Network (On-Net) as well as calls made On-Net to Off-Net.
4.2 On-Net to On-Net
These three cases include calls made from a user on an IPCablecom Network to a user on the same (or another) IPCablecom network.
4.2.1 Intra-zone
Intra-zone defines calls that remain within the technical control of a single CMS.
4.2.2 Inter-zone, Intra-domain
Inter-zone, intra-domain defines calls that remain within the domain of a single Kerberos Realm, but travel beyond the technical control of one CMS.
4.2.3 Inter-domain
The inter-domain case is not within the current scope of this Specification.
5.0 REQUIREMENTS FOR PREFERENTIAL TELECOMMUNICATIONS IN IPCABLECOM
The following requirements are for authentication and prioritization capabilities within IPCablecom networks. This initial set of requirements can be implemented utilizing existing mechanisms or extensions to existing mechanisms found within IPCablecom and elsewhere. Future enhancements as well as internetworking details will await the work of other ITU-T Study Groups.ANSI SCTE 173-1 pdf download.
