Product Description/Overview August 1999
DISCOVERY IP NETWORK COMPONENTS
A Discovery IP network consists of an IP network between at least two endpoints, and devices 
to convert standard voice signals into IP data packets for transmission on the packet network.  
The devices known as gateways are the DISCOVERY IP units.  Each Discovery IP connects to 
loop start CO line interfaces on a key system or PBX and to an IP LAN.  A conventional router 
connects the LAN to a...

2 Operational Modes
CALLING FROM POINT A TO POINT B
The Discovery IP is a conversion node where traditional voice telephone circuits are converted 
or packetized into digital information (IP packets) which are transmitted across a data network.  
At the other end of the connection, another Discovery IP converts the packetized voice back to 
analog information for the telephone network.  
The Discovery IP typically connects telephone systems together using the...
