QSIG Port Setting [Monitored PBX]
ISDN-QSIG (PBX Direct Connection)
Each QSIG port of a BRI card that will be used to transmit extension status information must be set to
do so through system programming. Even if a port is set to not transmit information, it will still receive
information from other PBXs.

IP-GW-QSIG
IP data is routed through the network according to the routing tables of the IP-GW cards. When using
a private IP network, it is necessary to identify the monitor PBXs, to which to transmit extension status
information, for each card that will be used. This is done by specifying the extension number of any
extension (for example, the PBX operator) at the monitor PBX as a Network Operator extension for that
IP-GW card.
