Glossary
Gbit/s
Gigabits per second
Geographic Location
Location of the ITM-SC server. the geographic location is entered as part of the
installation procedure of an ITM-SC.
Geographic Redundancy (GR)
Allows protection of management for a network element by assigning the network
element to two ITM-SCs. The first primary ITM-SC usually manages the Network
Element and is now in the protected domain. If the primary ITM-SC or the link between
the network element and the primary ITM-SC fails, the secondary ITM-SC will
automatically take over management of the network element and is now in the protecting
domain. The two ITM-SCs are connected by a peer to peer link, which they use to pass
Geographic Redundancy management information to each other. This link must be
established before any network element can be protected by Geographic Redundancy.
GFP
Generic Framing Procedure
Global Wait to Restore Time
The time to wait before switching back to the timing reference occurs after a timing link
failure has cleared. This time applies for all timing sources in a system hence the name
global. This can be between 0 and 60 minutes, in increments of one minute.
GNE
Gateway network element - A network element that passes information between other
network elements and operations systems via a data communications network.

H HE
Host Exchange
High Density Bipolar 3 code (HDB3)
Line code for example, 2 Mbit/s transmission systems.
High level Data Link Control (HDLC)
Protocol in the data-link layer of the OSI reference model.
Higher order Path Adaptation (HPA)
Function that adapts a lower order Virtual Container to a higher order Virtual Container
by processing the Tributary Unit pointer which indicates the phase of the lower order
Virtual Container Path Overhead relative to the higher order Virtual-Container Path
Overhead, and assembling/disassembling the complete higher order Virtual Container.
