T1 out-of-frame qualified alarm

The pack cannot synchronize the incoming T1 digital signal. An out of frame condition (OOF) is caused by loss of signal (LOS), an Alarm Indication Signal (AIS), or some other fault condition such as a defective transmission path, hardware failure, or incompatible T1 framing mode. The OOF condition is declared when received T1 framing bits are in error in the range 2 out of 4 to 2 out of 5. Error 17012 is reported if the OOF is caused by loss of signal; error 17013 is reported if the OOF is caused by receiving AIS.

Check that Blueworx Voice Response T1 framing mode (D4 or ESF) matches the framing mode of the terminating equipment (CSU, PABX, channel bank and so on). Determine the Blueworx Voice Response T1 framing mode by clicking Configuration... System Configuration... Trunk Interface and selecting the trunk concerned. D4 framing is normally used with CAS. Extended superframe (ESF) is normally used with CCS, for example, ISDN. If the configurations match, test the telecommunication line cable. Check the telecommunication cables and connections to the network. Check that all cable connectors are firmly seated. Run the diagnostics described in the Problem Determination information. If the cable and Blueworx Voice Response are OK, the problem is with the terminating equipment or the transmission path beyond the Blueworx Voice Response telecommunication line cable. Call Blueworx Support with the details and results of all tests you have tried.
