    Configuring Analog Port Parameters for CESoPSN Bundles (CTP Menu)

    Starting from CTPOS Release 7.0, you can configure a CESoPSN bundle on CTP2000 devices to transfer voice data between analog ports (FXO, FXS, and 4W ) and T1E1 ports. You can configure a maximum of 64 CESoPSN bundles on a CTP2000 device. The maximum number of CESoPSN bundles supported over analog ports is limited to 16 per node.

    Note: Runtime diagnostics is not supported for CESoPSN bundles configured over analog ports.

    To configure port parameters for analog interfaces for CESoPSN bundles by using the CTP Menu:

    1. From the Main Menu, select 1) Bundle Operations.
    2. Select 3) CESoPSN.
    3. Select a bundle from the list.

      If you select an active bundle, you are prompted to disable the bundle before configuring it.

    4. Select 3) Port Config.
    5. Follow onscreen instructions, and configure the options as described in Table 1.

    Table 1: CESoPSN Bundle Analog Port Parameter Settings on the CTP Menu

    FieldFunctionYour Action

    Voice port Tx gain

    Specifies gain in direction from the analog interface toward the IP network

    Enter a number from -15 dB through 10.4 dB.

    Voice port Rx gain

    Specifies gain in direction from the IP network to the analog interface.

    Enter a number from -15 dB through 10.4 dB.

    Signaling

    Specifies the type of analog signaling used.

    Select one:

    • ground start—Typically used between a central office (CO) and a PBX to prevent glare. Glare occurs when the FXS device establishes a call and the FXO device attempts to make a call before the ring is detected.
    • loop start—Typically used for residential phones.

    PLAR

    Enables or disables Private line automatic ringdown (PLAR) signaling. PLAR allows you to connect two 2W-FXS interfaces.

    You must set signaling to loop start before you enable PLAR.

    For PLAR to work, both ends of the bundle must have PLAR enabled.

    With PLAR, two handsets are directly connected so that when someone picks up a handset, the handset at the remote end starts to ring. There is no call routing (dialing) involved.

    To hear a ringback tone, you must enable tone detection for the bundle.

    Select one:

    • Enabled
    • Disabled
