Trunk Provisioning Service Selection
Each channel of a PRI interface can be dedicated to a particular service. Services are designated to
specific channels; once designated, a channel can be used only for that service.
Service Conditions
1. The services that can be designated include MEGACOM ® /WATS and MEGACOM ® 800/800WATS.
2. Arrangement with the carrier at the time of provisioning is needed.
Event Based CCIS This feature allows a PBX customer that does not have a tie line (or when a customer cannot
use the tie line due to the busy or fault of the line), to use the various CCIS feature by using
the ISDN line as a CCIS virtual tie line, on the 2400 IPX - 2000 IPS connection or the 2000 IPS
- 2000 IPS connection.
Service Conditions
1. Event Based CCIS is available between 2000 IPS to 2400 IPX and 2000 IPS to 2000 IPS.
2. The maximum number of virtual tie lines is 16 channels per system. This includes the common signaling
channels and voice channels.

4. This feature supports voice calls only. (Supported object at PBX transmission side: Single Line Telephone,
Multiline Terminal, DID/E&M/Ring Down (analog/T1) tandem calls). The data calls are transmitted via the
regular ISDN network.
5. The Peg Count (the number of originating call from the ISDN trunk) is counted when using the ISDN line for
the virtual tie line by route basis.
6. Billing information of the virtual tie line using the ISDN line is treated as regular tie line calls.
7. Billing information of the virtual tie line using the ISDN line is treated on tandem calls.
8. The voice channel of the virtual tie line is released at a programmable time after the call finishes.
9. The CCH (Common Channel Handler) card is required for providing Event Based CCIS.
