Srg50 Terminology - Nortel SRG50 Configuration Manual

• analog devices such as fax machines
The SRG50 is positioned primarily to support IP telephones and clients. However, analog devices
can be supported using analog station modules (ASM), or by using an analog terminal adapter
(ATA2) in conjunction with a digital station module (DSM). The SRG50 does not support digital
or ISDN telephones.

SRG50 terminology

The following table identifies SRG50 terms that may be unfamiliar to main office installers. They
are provided to facilitate communications between SRG50 and main office personnel. In the table,
EM refers to a path on the SRG50 Element Manager where the term appears; the paths are
provided for reference and may not represent every appearance of the term.

Description
For telephony configuration (EM: Configuration > Telephony), a port is an internal
number that identifies a physical termination point for a telephone set or a physical trunk.
For the configuration of resources (EM: Configuration > Resources) and data services
(EM: Configuration > Data Services), port is used in the context of the TCP/IP protocol
suite.

Trunks refer to external facilities that are connected to the SRG50 and provide incoming
and outgoing communication paths. Paths can be physical (examples: loop; PRI; T1) or
virtual (VoIP trunks).
EM: Configuration > Resources
An analog loop (FXO) that connects to the PSTN: a POTS line.
A line is the generic term used for all communication paths, both internal and external.
EM: Configuration > Telephony > Lines
Physical trunks.
