D

IP Gateway System
Description
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.
