CCIS Networking via IP C-163
C-163 CCIS Networking via IP
General Description
This feature allows the system to utilize the CCIS network over Internet/Intranet. To establish or release a call, an
IPTRK card is used for both speech and signal channels.
Operating Procedure
No manual operation is required.
Service Conditions
1. To send or receive speech and CCIS signals, each node shall use an IPTRK circuit card(s). At this time,
the IPTRK cards in the self-node and each of its connected node must be in 1-to-1 ratio, respectively
(point-to-point connection).
2. Two IPTRK cards per unit are the maximum. Accordingly, a total of 16 IPTRK cards can be
accommodated per IMG.
3. Only voice and FAX (G3) information can be sent or received via IPTRK card.
4. The port, assignable for CCIS signaling, is only the 1st LEN of each HW block. Other ports are to be used
for speech channels.
5. A D-channel, assigned on an IPTRK card, can control the B-channels of the same card, and also those of
a maximum of 7 other IPTRK cards.
6. Tandem Path through function is not provided.
7. This feature supports QoS (Quality of Service) function.
8. When a system message indicates “TCP link failure” due to data congestion on the router or IP network,
a call cannot be made via an IPTRK circuit card. When a call is attempted despite this, the caller hears
busy tone.
9. When a system message related to “TCP link failure”, is created during call origination or speech, that
call’s speech channel is automatically restored via patrol function.
