Connection options

Communications between the Remote Gateway 911x series unit in your office
and the host PBX takes place using 10BaseT Ethernet interface to an Internet
Access Device (IAD) on a corporate wide area network (WAN) or an analog
connection, or both. This section provides a description of each of these
connections.

10BaseT Ethernet interface

The Remote Gateway 911x series unit uses Nortel proprietary Voice over IP
(VoIP) technology over the IP network to the host PBX. Voice data is forwarded
as UDP/IP packets and the signalling data as TCP/IP packets. You can connect
the Ethernet interface to an Internet Access Device such as a BRI router, an
xDSL modem, or cable modem. For more information, refer to the "Internet
Access Device description" on page 10.
Note: The Remote Gateway 911x series unit uses a half-duplex 10BaseT
Ethernet connection.

PSTN connection

The Remote Gateway 911x series unit includes a built-in V32.bis modem. If you
do not have a data connection to the host site, you can connect the Remote
Gateway 911x series unit to the PSTN. The Remote Gateway 911x series unit
transmits both voice and signaling data to the host site over the PSTN.
Note: The Remote Gateway 911x series units do not support DSL analog lines.
