D
term
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 and feeds the WAN signals 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 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 workers, 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.
When 5-, 6-, or 7-digit station numbers are used (R2000 or higher), this
feature is unavailable.
