CLI Command List

Set DS0 Service

Purpose: Sets a DS0 channel, or range of channels (up to 24), to the up (In Service) or down (Out of Service) state. DS0s for ISDN BRI circuits can also be set up or down. Alarming is enabled when channels are in service.

To prevent alarms, it is recommended that the CRVs for unused ISDN BRI circuits be set Out of Service at the GR-303 switch, which will cause the switch to ignore D channel signaling for the unused CRVs. Unused B1 and B2 channels can either not be provisioned or be provisioned and then set Out of Service until needed.

NOTE: If a GR-303 switch or drop DS0 is set down, calls will not pass in either direction.

NOTE: Unused ISDN BRI circuits can be set Out of Service by either setting down the B1 and B2 channels or not provisioning them. D channels are treated differently depending on the transport mode. Normally, a 4:1 TDM mode D channel should not be set down because all four CRVs assigned to the D channel would be put out of service. A 3DS0 mode D channel can be treated the same as any other crossconnection between drop and groom DS0s.

Security: Level 2 (operator)
