Digital Telephone External IP Adapter

The Digital Telephone External IP Adapter connects to the telephone set line
cord of the digital telephone with a standard RJ-11 connector. The unit relays
voice and signaling information between your digital telephone at a remote
location and the RLC installed in the host PBX over the IP network. Refer to the
following chapters for additional information:
Chapter 3, "Installing the Digital Telephone IP Adapter unit"
Chapter 4, "Configuring the IP Adapter unit using the telephone menu", or
Chapter 5, "Changing configuration settings using Configuration Manager"

Reach Line Card

The Reach Line Card (RLC), installed in the host PBX, provides service for up
to 16 ports on a single-slot card or 32 ports on a double-slot card. The RLC
emulates a standard digital line card (XDLC), providing PBX functionality for
telephones at remote locations (including sites using the Digital Telephone IP
Adapter unit).
The RLC relays voice and signaling information between the remote digital
telephone and the host PBX over the IP network.
For a more detailed description, refer to the Reach Line Card Installation and
Administration Guide (NTP 555-8421-210).

Voice over IP technology

The Digital Telephone IP Adapter unit uses Nortel proprietary Voice over IP
technology to send voice and data signals between your office and the host PBX
through the existing IP data network.
