Bri Trunks; Pri Trunks - Nortel ICS Install Manual

BRI trunks

BRI trunks give you incoming and outgoing access to an ISDN
network. Like loop start trunks, they can be configured as
manual-answer or auto-answer. See Ans mode on page 369.
BRI trunks provide a fast, accurate, and reliable means of
sending and receiving data, images, text, and voice
information. Using BRI lines allows for faster transmission
speeds and the addition of a variety of powerful business
applications, including remote LAN access, video
conferencing, file transfer and Internet access.
For more information, see Welcome to ISDN on page 53.
Note Profile 2: European BRI trunks can only be EURO
trunks.

PRI trunks

PRI trunks are used for incoming and outgoing calls over an
ISDN network. PRI trunks are automatically set to auto-
answer.
Incoming calls are routed to system telephones through
assigned target lines. Outgoing calls are made using the
intercom key assigned to a PRI line pool, or by entering a
destination code to which a route has been defined using PRI
line pools. You cannot assign a PRI line directly to a
telephone.
PRI SL-1 lines also can provide MCDN network functionality
over a private network between other Norstar systems,
Meridian 1 systems, or Business Communications Systems, if
the appropriate keycode has been installed. Private networking
is described in Networking with Norstar on page 109.
