Administering BRI parameters

Last Updated : Jul 20, 2020 |

Procedure

  1. Enter bri <slot-address>, where <slot-address> is any permitted port.

    The command line prompt changes to sls-bri <slot-address>. If you want to remove the BRI link from the SLS administration, enter exit to leave the second-level bri context and return to the (super-sls)# context, and then enter clear bri <slot-address>.

  2. Enter set name <name> to identify the user name for the DS1 trunk.

    Use the 1-27 character name, as specified on CM (add trunk-group n). Type the name string inside double quotes.

  3. Enter set interface <glare-mode> to specify the glare-handling convention.

    <glare-mode> can be one of the following values:

    Option Description

    For non-QSIG calls:

    For QSIG calls:

    • network. If the Branch Gateway is connected to a host computer and encounters glare, it overrides the far-end

    • user. If the Branch Gateway is connected to a public network and encounters glare, it releases the circuit

    • peerMaster. SLS overrides the other end when glare occurs

    • peerSlave. SLS releases the circuit when glare occurs

  4. If the BRI link is employed with ISDN, and the glare-handling convention is specified as peerMaster or peerSlave for the ISDN link (set in Step 3),
  5. Enter set side <side> to specify the glare mode: either a or b.
  6. If the BRI link is employed with ISDN, enter set country-protocol <country-code> to specify the ISDN Layer 3 country protocol type, where <country-code> is any of the values listed in ISDN Layer 3 country codes.
  7. If the BRI link is employed with ISDN, enter set bearer-capability <bearer> to set the Information Transfer Rate field of the Bearer Capability IE, where bearer is one of the following values:
    • 3khz. 3.1 kHz audio encoding

    • speech. Speech encoding

  8. Enter set interface-companding <type> to set the far-end companding method, where <type> is one of the following values:
    • alaw. A-law companding

    • ulaw. U-law companding

  9. If the BRI link is employed with ISDN, enter set tei-assignment <tei> to select the method by which the Layer 2 (LAPD) protocol obtains its Terminal Endpoint Identification (TEI) address.

    tei is one of the following values:

    • auto. TEI is assigned by the network provider

    • zero. TEI is fixed administratively

  10. Enter set directory-number-a <number> to assign a directory number to the B1 channel of the BRI link.

    <number> is the provisioned number received from the network provider. The number value must be identical to the number the network provider has assigned to the circuit.

  11. Enter set directory-number-b <number> to assign a directory number to the B2 channel of the BRI link.

    <number> is the provisioned number received from the network provider. The number value must be identical to the number the network provider has assigned to the circuit.

  12. Enter set spid-a number to assign an SPID to the B1 channel of the BRI link.
  13. Enter set spid-b number to assign an SPID to the B2 channel of the BRI link.
    Note:

    All BRI links must have SPIDs properly configured for the link to function. SPIDs are received from the network service provider.

  14. If the BRI link is employed with ISDN, enter set-endpoint-init {yes | no} to determine whether or not the far-end supports endpoint initialization.
  15. If the BRI link is employed with ISDN, enter set layer1-stable {yes | no} to determine whether or not to keep the physical layer active (stable) between calls.

    Some European countries require that the physical layer is deactivated when there is no active call.

  16. Enter show to check the BRI administration.

    The report lists the BRI parameters. For example:

    Name = BRI-SLS1
    BRI   Interface    Side   Country   Bearer   Compand   Endpt-Init   Layer1-Stable
    ---   ---------    ----   --------  ------   -------   ----------   -------------
    v301       user       a   country1  speech      ulaw          yes             yes
    Dir-NumberA Dir-NumberB Spid-A          Spid-B
    ----------- ----------- -------------- --------------
     3033234567  3033234568 30332345671111 30332345681111
  17. Enter exit to leave the bri context in SLS.
