VOLIB CID Problem

Ferhat OLGUN
Expert 1080 points

Hi,

I am using VOLIB in C5507 DSP and CID component gives an error for some patterns and does not detect caller ID.

The error is "cid_RPT_LONG_MARKS" from call-back function which states  ">20 consecutive marks encountered in message". What does it mean?

The problem occurs especially on SDMF(Single Data Message Format) CIDs. Is there any known issue for SDMF format?

Attached both the succesful and unsuccessful 8bit alaw vaw samples.

    Hi,

    The problem seems that VOLIB ETSI allowed message types do not include 0x04 SDMF. When I set US - Telcordia detection control code, it can detect SDMF formats.

    Why does VOLIB CID not include SDMF for ETSI?

    Regards

    Ferhat,

    The CID module in the VOLIB complies with the following standards:

    • Telephone Service Interfaces Edition 5 - Nippon Telegraph and Telephone Corporation (NTT)

    • ITU-T Recommendation V.23, 11-1988, 600/1200-baud modem standardized for use in the general switched telephone network

    In the control_code: /* 1 - US, 2- NTT, 3 - ETSI, 4 - YDN, 5 - BT 6 - AUS*/

    For the ETSI supports:

    /* ETSI allowed message types */
    #define cid_ETSI_CS_MSGTYPE   0x80 /**< Call Setup */
    #define cid_ETSI_MWI_MSGTYPE   0x82   /**< Message Waiting Indicator */
    #define cid_ETSI_AOC_MSGTYPE   0x86   /**< Advice of Charge */
    #define cid_ETSI_SMS_MSGTYPE   0x89   /**< Short Message Service */
    #define cid_ETSI_NOUMIN_MSGTYPE  0xf1   /**< Reserved for Network Operator Use */
    #define cid_ETSI_NOUMAX_MSGTYPE  0xff

    There is no support of SDMF message type. I am sorry I don't know why, this is the package we have and there is no further development work for this.
