FCCS Networking via IP F-36
Service Conditions (cont’d)
FCCS via IP using Cisco router
1. DTI (1.5M and 2.0M) interface is used as speech channel.
2. The FCH-FGH card is used as a signal channel. Only a single FCH-FGH card can be connected to a router.
Accordingly, redundant configuration of FCH-FGH is not available.
3. An interface number is assigned to each speech channel and is changed into the TCP/IP port number
between PBX and router for speech channel control.
4. The TCP/IP port number for the TCP/IP (FCCS) packet, which is not controlled at speech channel, should
be different from that for the interface number. The TCP/IP packet is transmitted between PBXs such as
upon remote log-in to another node with Windows MAT. At this time, only the routing for the TCP/IP
packet is performed by the router.
5. The channel number and the connected-to router (router access number as termination number
information) can be recognized by adding Q.SIG message to TCP/IP packet, which makes speech channel
control between PBX and router available.
6. The router applying to FCCS Networking via IP service must be used.
7. The maximum number of digits for the router access code is 16.
