Digital Telephone IP Adapter description 

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 4, “Configuring the IP Adapter unit using the telephone menu”, or 
Chapter 5, “Changing configuration settings using Configuration Manager”

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).

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.
