  • BRI Config questions

    Hi,

    Could anyone tell me the config for a bri ISDN circuit please?

    The carrier is saying I need:

    Signalling - ETSI
    Coding - HDB3
    Framing - CRC4
    Clocking - Line

    I have it configured as:

    Protocol type: ISDN User
    Central office type: Euro ISDN
    Signalling: Point to point
    Clock source: Slave
    Priority: High

    I have DTMF issues and am wondering if I am missing something obvious.

    getting errors when telneted into the 90BRI I am seeing the following:

    trunk_isdn_dial_done_event([p 6]) unexpected
    trunk_isdn_dial_done_event([p 6]) unexpected
    trunk_isdn_dial_done_event([p 6]) unexpected
    trunk_isdn_dial_done_event([p 6]) unexpected
    ERROR : SIPIntf_util.c:571 : errorCode: (-5)Out_of_Range (sip_publish_get_media_stats)
    WARNING : SIPIntf_sip.c:4098 : errorCode: (-5)Out_of_Range (sipintf_sip_dvc_media_stats)

    The first 4 lines are when sending DTMF.

    I also have a PRI and that works fine so it is something specific to the BRI ccts.

    Many thanks, Ian

    I would try adjusting the Transmit Gain (TX Gain) of the E1. Try increasing to 2DB, 4DB, and then 6DB. Test DTMF after each change and also be sure the volume for the person speaking does not become too loud. It is not necessary to reboot the switch, however, i would restart the TMS service for stability. The inverse of this can also be a problem for DTMF. For instance, if the TX Gain is set at 12DB, DTMF will be so loud the far end may not recognize the tones. TX Gain should rarely exceed 6DB.
