Creating a signaling group for SBS

Last Updated : Oct 04, 2016 |

Procedure

  1. Enter add signaling-group n, where n is the signaling group number.
  2. Make sure the Group Type field is set to H.323
  3. Set the Max number of NCA TSC field to a number greater than zero.

    Non Call Associated Temporary Signaling Connections (NCA TSC) are used to establish connections and pass messages for features like Message Waiting Indication (MWI) activation and deactivation. QSIG protocol establishes and releases the NCA TSC for each MWI session. When a TSC is established between two Communication Manager systems it sends the message it was established for. The TSC then stays up until there have been a few minutes of inactivity. Depending on traffic, this TSC can be used for multiple messages.

    A TSC that is established between a Communication Manager system and a messaging system will be taken down after the initial message is sent.

  4. Set the SBS field to y.

    The system displays this field only when the Group Type field is set to H.323.

  5. Set the Trunk Group for NCA TSC field to same number as the SBS trunk group.
  6. Set the Trunk Group for Channel Selection field to the same number as the SBS trunk group.
  7. Always set the TSC Supplementary Service Protocol field to b.
  8. Set the Near-end /Far-end Listen Ports fields to equal the far-end value on the distant switch.

    The near-end value on the distant switch must match the far-end value on this near-end switch.

    Note:

    A signaling group that is used for SBS trunks cannot be used for non-SBS trunk groups. The Near and Far-end Node Names are defined using the change node-names ip administration form.
