General Description
With this feature, an FCCS trunk call can automatically be routed via a non-FCCS trunk (C.O. or Tie Line), if all
the FCCS trunks are busy or a Data Link Failure occurs at the FCH card.
Operating Procedure
No manual operation is required.
Service Conditions
1.
This feature is activated when all FCCS trunks are busy, a transmission failure occurs, or FCCS Link
Failure (Layer 2 down) occurs at the FCH card.
2.
Call origination through a trunk assigned as an alternative route should be established normally.
Numbering plan data for the external alternative route should be programmed prior to this feature.
3.
This feature is available only when the called party is an analog station, a D
feature is not available for a wireless terminal, or a DAT/Paging trunk.
4.
When an incoming call from C.O./Tie Line encounters all FCCS trunk busy and it is routed to a Tie Line
trunk by this feature, the normal Tie Line service is applied.
5.
Only the LCR or LCRS is applied for alternate routing to a Tie Line/C.O. line for Tie Line. (The signaling
system is limited to ISDN or CCIS.)
6.
The access code for the alternative route is a maximum of 24 digits, assigned by the AFRFL command.
7.
When the selected non-FCCS trunks (LCR/LCRS) are also busy, route selection is performed according
to the LCR/LCRS table. The same is performed when the section encounters an FCCS trunk busy again.
