	Note: There are several differences in administration between switches.
		For example, PRI is translated a little differently in G3r when
		traditional DCS and this feature are used in combination. On
		systems with AUDIX in a DCS environment, an additional column
		has been added to the Signaling Group form so you can specify
		which AUDIX and switch to use. When traditional DCS and DCS
		over ISDN are used in combination, translations are also different.

Detailed description A TSC provides a temporary signaling path through ISDN switches for exchanging supplementary service information on ISDN-PRI D-channels. There is no B-channel related to the connection; no data or voice transmissions take place.

There are two types of temporary signaling connections:

•Call Associated (CA-TSC)

•Non-Call Associated (NCA-TSC)

CA-TSC

A CA-TSC refers to a service for exchanging USER INFORMATION messages associated with an ISDN B-channel connection by the call reference value of the call control data packets. On DEFINITY ECS, this type of TSC is used only for DCS features on ISDN-PRI Signaling Groups administered with Supplementary Service Protocol a.
