This document is identical to SCTE 95 2009 except for informative components which may have been updated such as the title page, NOTICE text, headers and footers. No normative changes have been made to this document.
This document contains information about the background of the Hybrid Management Termination System
(HMTS). This document is a companion document for the HMTS MIB, and does not replace the MIB.
Although this document has been written to be consistent with the HMTS MIB, in case there would be any
conflicts between these two documents, the MIB is the reference.

TERMS AND DEFINITIONS
This document defines the following terms:
Manageni ciii Information Base MIB) – the specification of information in a manner that allows standard access through a network management protocol.
HIlTS: Hybrid Management Termination System.
IIMS: 1 lybrid Management System.
E3’IS: Element Management System.
NO-COIJMS: A condition that exists when the IIMTS cannot establish round trip communication with a
HMS device.
XP: Abbreviation for transponder.
IP: Internet Protocol.
TCP: Transmission Control Protocol.
SNMP: Simple Network Management Protocol.
ICIIP: internet Control Message Protocol.
MAC’: Media Access Control. Basically a data packet definition that provides for end to end transmission of data between two network elements.
BroadcasiAddress: A MAC specific address value that all devices will recognize and process requests to, but not reply to.
Mufticast Address: A MAC specific address value that can be configured into multiple devices such that a group is created. Use of a multicast address will cause all members of the group to act upon the request, but none of the members will reply. This differs from the broadcast address only in that all devices arc preconfigured with the broadcast address.
U,iicast Address: A MAC specific unique address that is used to identify what device is to process a message and return a reply.
Round Robin: A method of processing a list of items which consists of starting with the first entry in the list and walking through the entire list in sequence, wrapping back to the first item in the list.
Forward Path /Returii Path: bi-directional communication requires a forward (from HMTS to HMS device) and return (from HMS device to HMTS) path (communication connection) regardless of the type of port in use.ANSI SCTE 95 pdf download.
