Paradyne 317x E1 manual Near End Group ± ªdsx1LineStatusº Object dsx1ConfigEntry

Near End Group ± ªdsx1CircuitIdentifierº Object (dsx1ConfigEntry 8)

This object is only supported on the network interface.

Near End Group ± ªdsx1LoopbackConfigº Object (dsx1ConfigEntry 9)

This object specifies the loopback state of the E1 interfaces. Only the following values are supported by the E1 DSU/CSU.

•dsx1NoLoop(1) ± The E1 interface is not in a loopback state.

•dsx1PayloadLoop(2) ± Specifies that a Payload Loopback (PLB) is active for the network interface or a Repeater Loopback (RLB) is active for the DTE Drop/Insert interface.

•dsx1LineLoop(3) ± Specifies that a Line Loopback (LLB) is active for the network interface or a DTE Loopback (DLB) is active for the DTE Drop/Insert interface.

Near End Group ± ªdsx1LineStatusº Object (dsx1ConfigEntry 10)

This object specifies the line (alarm) status of the E1 interfaces. Only the following values are supported by the E1 DSU/CSU. More than one value may be active at a time.

•dsx1NoAlarm(1) ± No alarm present.

•dsx1RcvFarEndLOF(2) ± A Remote Alarm Indication (RAI) signal is being received.

•dsx1RcvAIS(8) ± An Alarm Indication Signal (AIS) is being received.

•dsx1LossOfFrame(32) ± An Out Of Frame (OOF) condition has persisted for more that 2.5 seconds.

•dsx1LossOfSignal(64) ± A Loss of Signal (LOS) condition has persisted for more that 2.5 seconds.

•dsx1LoopbackState(128) ± The near end of the E1 interface is in a loopback state.

•dsx1Other Failure(4096) ± An Excessive Error Rate (EER) has been detected on the network interface.

Near End Group ± ªdsx1SignalModeº Object (dsx1ConfigEntry 11)

This object specifies whether time-slot 16 (TS16) is reserved for signaling. Only the following values are supported by the E1 DSU/CSU.

•none(1) ± No signaling is being used on this interface.

•messageOriented(4) ± Indicates that TS16 is reserved for signaling.

Changing from none(1) to messageOriented(4) deallocates all DS0 channels on the DTE and network interfaces.

Near End Group ± ªdsx1TransmitClockSourceº Object (dsx1ConfigEntry 12)

This object specifies the timing source for the currently active transmit clock for this E1 interface. This may be either the primary clock source, secondary clock source (if the primary has failed), or the internal clock (if both primary and secondary have failed). This object differs from the MIB definition in that it is ªread-onlyº (not read/write) for E1 DSU/CSUs. Only the following values are supported by the E1 DSU/CSU.

•loopTiming(1) ± The recovered receive clock is being used as the transmit clock.

•localTiming(2) ± The E1 DSU/CSU's internal clock is being used as the transmit clock.

•ThroughTiming(3) ± The recovered receive clock from another interface (e.g., E1, Port, or External) is being used as the transmit clock.
