The T1/E1 Voice Modules support transparent Common Channel Signaling (CCS), an application that allows high-speed transport of voice over the Passport network. CCS uses one T1 or E1 DS0 channel to transmit signaling information for all the remaining voice/data DS0 channels (23 T1 or 30 E1). Typically time slot 24 for T1 or time slot 16 for E1, is assigned as the signaling channel. The following topics are included in this section:
Describes the characteristics associated with Transparent CCS signaling.
Describes the physical and logical components involved in implementing transparent CCS between two digital PBXs.
Describes the configuration requirements for successful Transparent CCS operation.
Describes the sequence of events for placing a Transparent CCS call.
