Chapter 5. Configuration Menu

Robbed Bit Signaling

This menu option is used to enable/disable robbed-bit signaling.

Whenever the base DS-1 interface is connected to termi- nal equipment (e.g., PBX/SW56) for voice or dialed data services, this option should be enabled.

Exception: When the terminal equipment is using a form of common channel signaling (e.g., PRI).

For applications requiring robbed-bit signalling as well as a messaging channel (e.g., some proprietary PBX channels), the ON: ENA BLOCK selection is provided. Choices: OFF, ON: ALL DSOS, ON: ENA BLOCK

RBS Start

When Robbed Bit Signaling option is set to ON: ENA

BLOCK, this item defines the first DS0 to extract signaling from.

RBS End

When the Robbed Bit Signaling option is set to ON: ENA BLOCK, this item defines the last DS0 to extract signaling from.

Example: RBS Start and RBS End together define a block of DS0s for Robbed Bit Signaling.
