EVENT BASED CCIS - ISDN TRANSPORT
E-23 EVENT BASED CCIS - ISDN TRANSPORT
1. General Description
This feature provides VIRTUAL TIE LINE for each event such as call origination and MCI message
transmission. Inter-PBX link for this feature is established on B-channels of the public ISDN line using CCIS
No. 7 signaling protocol. For addressing a specific terminal, Called Sub Address or Called DID Number is used
depending on the network configuration.
2. Operating Procedure
None.
3. Service Conditions
1. The ISDN Primary Rate Interface (PRI) trunk is used for this feature.
2. The following ISDN interfaces are available:
4 ESS
DMS 100
N-ISDN2
3. When using Called Sub Address as addressing information:
(a) channel negotiation and Sub Address-Addressing must be available in the public ISDN network.
(b) different DID Numbers must be assigned to the ISDN line, the E-CCIS line and its alternate route. For
the E-CCIS line, DID Number is required for each D-channel.
(c) Sub Address assigned to the E-CCIS trunk must be common to both offices.
4. When using Called DID Number as addressing information:
(a) a different DID Number is required for each channel of the E-CCIS line.
(b) when channel negotiation is not available, call termination to an E-CCIS trunk must not be allowed
except when DID Number assigned to the trunk is dialed.
(c) different DID Numbers must be assigned to the ISDN line and the E-CCIS line. For the E-CCIS line,
DID Number is required for each D-channel.
(d) alternate route for the E-CCIS line cannot be assigned.
5. Each trunk for the E-CCIS line cannot be used for the public ISDN line.
6. Each channel used for a E-CCIS line must be controlled by a single D-channel (i.e. Each channel must be
assigned to a single ISDN line).
7. Billing information on the E-CCIS line does not include Access Code or Converted Number.
