No. 7 CCIS
The PBX can provide No. 7 CCIS via either a digital network or an analog network. Regardless of the dig-
ital network or analog network, CCH (Common Channel Handler) to control the common signaling chan-
nel is required.
Digital Network
When No. 7 CCIS is provided via a digital network, the CCH is connected to the DTI by a fixed path in
the TDSW and transmits/receives common signaling data to/from the distant office through a predeter-
mined channel. Voice signals are transmitted/received on each line basis through other channels.
This figure shows the system configuration of No. 7 CCIS provided via digital network.
