A Screens Reference
ISDN TSC Gateway Channel Assignments
This screen is required when the switch is to act as a gateway between a switch that supports the Temporary
Signaling Connections (TSC) feature and a non-TSC-compatible switch. The gateway provides interface
protocols necessary for communications to exist between a switch administered with Non-Call Associated TSCs
in a Signaling Group on the ISDN side and a processor channel (BX.25) on the non-ISDN side. A NCA-TSC is a
type of virtual connection established for exchanging user information messages on ISDN-PRI D-channels.
There is no B-channel related to the connection.
Sig Group Used to indicate the Signaling Group to which the NCA-TSC belongs.
Adm’d NCA TSC Index Used to indicate the administered NCA-TSC that acts as one endpoint of the gateway.
