E1 2MB alarm indicator signal qualified alarm

The 2MB Alarm Indication Signal (AIS) is a continuous stream of binary 1s transmitted in all timeslots of the E1 digital signal. When this error occurs, Blueworx Voice Response sends the Remote Alarm Indication (RAI) signal to the far end. If the terminating equipment (PABX, channel bank, and so on) shows RAI, the transmission path from Blueworx Voice Response to the terminating equipment, the transmit side of Blueworx Voice Response, and the receive side of the terminating equipment are probably functioning correctly. (See explanation for 17007).

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. Run appropriate diagnostics on the terminating equipment to see why it is generating a 2MB AIS. If the problem persists, call Blueworx Support with the details and results of all the tests you have tried.
