Digital Telephone IP Adapter Installation and Administration Guide 41
January 2005 Digital Telephone IP Adapter description
Voice over IP network call
1 The Digital Telephone IP Adapter user lifts the handset (item A).
Result: The Digital Telephone IP Adapter user hears a dial tone. This
indicates a successful connection to the RLC over the IP network and the
corporate WAN (item B).
2 The Digital Telephone IP Adapter user dials the external telephone number.
Result: The Digital Telephone IP Adapter unit sends the dialed digits as
packets across the Ethernet network. The packets go through the IP
network and the corporate WAN, to the RLC. The RLC converts the
packets to the format required by the host PBX. The host PBX then
converts the data to voice and routes the call to the called party (host
stations 1 and 2).
Note: Item notations in parentheses refer to circled markers in the diagram on
page 40.
