IP Gateway System
The D
term
IP Gateway system converts traditional voice traffic and its accompanying
signaling for call setup and networking to IP for transport across a managed IP
network. The system allows users at branch offices or telecommuters to take
advantage of the rich feature set of the company central site Key Telephone System
as though they were connected locally without loss of functionality. Traditional voice
traffic (plus call setup and networking signaling) travel from the KTS to the Gateway
where they are converted to IP packets that are shipped to a 10 Mb (Gateway) or 10/
100 (Gateway II) Ethernet LAN port. They are then picked up by the enterprise router
and sent to the corporate WAN.
At the branch office, the local router receives the WAN signals and feeds them to the
local 10/100 LAN. From there they reach the D
term
IP Branch unit that converts the IP
packets back to standard (TDM) voice signals for distribution to attached D
term
Series
E/Electra Elite telephones. The D
term
IP Branch supports up to 12 voice circuits.
When the remote site is a telecommuter at home or only a few users, the remote IP/
TDM conversion is performed by a D
term
IP Adapter that fits easily on the bottom of a
standard D
term
Series E telephone.
