cisco Integrated CSU DSU Sw56k Loop Status

1.3.6.1.4.1.9.9.44.1.3.2.1.2

Current loop status or alarm condition. Represented as a sum of a bit map. The variable bit positions are: 1 oosOofFromNetwork - The DSU is receiving Out of Service/ Out of Frame code from network indicating network trouble. This can be a problem with a device at the remote DSU. The most common cause of the this error is either the remote DSU is powered off or the remote telco connection is open. 2 noReceiveSignal - The DSU has detected sealing current from the central office but the receive level is below -45db. 4 noSealingCurrent - the DSU does not detect sealing current on the loop interface. This is normal for a private network. 8 noFrameSync - At 64k data rate the local loop operates at 72k with a framing pattern added to maintain byte alignment with the network. This condition is reported if the DSU cannot find the framing pattern. 16 attemptingToRateAdap - Set in 'autorate' mode when the DSU is searching for the loop rate. 32 rtTestFromTelco - Set when the DSU in telco initiated RT test. 64 llTestFromTelco - Set when the DSU in telco initiated LL test or when the transmit and receive pairs are reversed. 128 rdlFromRemoteDSU - Set when remote digital loopback initiated from remote DSU.
