will be disconnected.

VOIP Networking
Two SBX IP 320 Systems can be connected through the VOIB. The networking CO line
connects the networking Systems and it is used for the network signaling message and voice
path. To use the networking CO line, the service type must be set to DID/MSN at PGM 140.
And to receive the net call digit information correctly, the appropriate DID conversion type must
be set at PGM 143 - FLEX 4. In the following example, DID TYPE 1 satisfies the situation. To
configure the net CO line connection, the net CO group and type must be set to '01' and 'NET'
at PGM 322 - FLEX 1 & 4.
