ISDN-QSIG (PBX Direct Connection)
Each QSIG port of a PRI 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 VoIP,
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.
