Connection options
Communications between the Digital Telephone IP Adapter 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). This section
provides a description of this connection.
10BaseT Ethernet interface
The Digital Telephone IP Adapter 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 34.
Note: The Digital Telephone IP Adapter uses a half-duplex 10BaseT Ethernet
connection.
