Adding PRI trunks (GT01 & 02 only)

FortiVoice Gateway Primary Rate Interface (PRI) carries multiple DS0 voice and data transmissions to your PRI service providers and through them to the outside world.

To view the PRI trunks

  1. Go to Gateway > PRI.

     

    GUI field

    Description

    Enabled

    Select to activate the trunk.

    Name

    The name of the trunk.

    Status

    The trunk statuses, including:

    • In service: The trunk is currently in use.
    • Not activated: The trunk is not enabled.
    • Idle: The trunk is not in use.
    • Unavailable: The trunk is not reachable.
    • Conflict: The trunk conflicts with another one.
    • Alarm detected: There is a problem with the trunk.
    • Admin down: The trunk is disabled.

    Type

    The trunk type: analog.

To add a PRI trunk

  1. Go to Gateway > PRI.
  2. Click New.
  3. Configure the following:

     

    GUI field

     

    Description

    Trunk Setting

     

     

    Name

    The name of this trunk. This is view only.

     

    Enable

    Select to activate the trunk.

     

    Display name

    Enter your caller ID that will appear on the called phone, such as Example Company.

     

    Number

    Enter the phone number that will appear on the called phone.

    Hardware Property

    Use this option to configure the T1/E1 span.

    Spans represent trunks (spans) of T1/E1 PSTN lines. The FortiVoice unit supports T1/E1 lines according to the installed voice card. You can add a span name using the CLI.

     

    Edit span

    Select the span you want to modify and click the Edit icon.

    For more information, see Configuring the T1/E1 span.

     

    Span

    Use this option to configure the PRI trunk.

    Select a span in the Available field and click -> to move it into the Selected field.

     

    Max channel

    Indicates the total number of B channels of the spans.

     

    Max outgoing channel

    Enter the number of outgoing channels out of the maximum number of B channels.

    Fax

    Configure fax and phone signal automatic detection and fax handling.

     

    Automatic fax detection

    Select for the FortiVoice unit to detect incoming fax signal on this trunk automatically.

     

    Forward fax to eFax account

    Select the fax receiving account for the detected faxes.

    Phone Number

    Click New to add the phone number provided by your PSTN service provider. Your PSTN service provider will direct calls from external callers directly to this number. You can add multiple numbers.

  4. Click OK.

Configuring the T1/E1 span

You can configure the settings of the T1/E1 span, including full or fractional PRI (T1/E1), to match the same settings of your PSTN service provider.

Note

For GT02, if a PRI trunk includes two spans, the configuration of the second span is much simpler as the spans share many configurations.

For more information, see Hardware Property.

To configure the T1/E1 span

  1. Go to Gateway > PRI.
  2. Select a span name and click Edit.
  3. For Edit span under Hardware Property, select a span and click the Edit icon.
  4. Configure the following:

    GUI field

     

    Description

    Standard Options

     

     

    Name

    The name of this span. This is view-only.

     

    Type

    Select the span type: PRI T1 or PRI E1.

    A T1 span usually supports 23+1 channels, while an E1 span supports 30 channels in CAS (Channel Associate Signaling) mode and 30 B channels and one D channel in ISDN mode.

     

    Signalling

    Select the signaling type of the ISDN PRI:

    PRI signalling, CPE (Customer Premises Equipment) side

    PRI signalling, Network Side

    PRI R2 signalling

    Advanced Options

     

     

    Framing and coding options

    Specify the type of framing and coding to provision the PRI with your PSTN service provider.

     

    Clocking options

    Select the FortiVoice unit’s clock synchronization:

    • Clock sourcing from PSTN network
    • Internal clocking source

    This option does not need to match that of your PSTN service provider.

     

    Receive sensitivity

    Select the level of receiver sensitivity which is the ability of the phone receiver to pick up the required level of phone signals to make it operate more effectively within its application.

    This option does not need to match that of your PSTN service provider.

     

    D-channel signalling format

    Select a signalling method for the D channel which is a signalling channel and carries the information needed to connect or disconnect calls and to negotiate special calling parameters (for example, automatic number ID, call waiting, data protocol). The D channel can also carry packet-switched data using the X.25 protocol.

     

    Line build out

    Select the line build out (LBO).

    LBO settings are an inherent part of T1 and T3 network element transmission circuitry.

    Since cable lengths between network elements and digital signal cross-connect (DSX) vary in the central office, LBO settings are used to adjust the output power of the transmission signal to achieve equal level point (ELP) at the DSX.

     

    D-channel

    By default, depending on your selection of Type, the typical channel numbers are:

    • Full T1: 24
    • Full E1: 16

    You can also set the channel numbers to others such as 1.

    The settings you configure must match the same settings of your PSTN service provider.

     

    B-channel

    By default, depending on your selection of Type, the typical channel settings are:

    • Full T1: 1-23
    • Full E1: 1-15, 17-31

    You can also configure the fractional channel numbers. For example, for T1/E1, the channels can be:

    • 1-12
    • 2, 3, 4, 9-15
    • 2-4, 9-15

    The settings you configure must match the same settings of your PSTN service provider.

    PRI R2 Setting

    Since there is no single signaling standard for R2, the FortiVoice Gateway addresses this challenge by supporting many localized implementations of R2 signaling.

    This option is active only if you select PRI R2 signalling for Signalling.

     

    Country

    Select the country for PRI R2 settings.

     

    Max ANI digits

    ANI (Automatic Number Identification) is a system used by telephone companies to identify the DN (Directory Number) of a calling subscriber. It allows subscribers to capture or display caller’s telephone number.

    Enter the number of digits of a caller‘s phone number to be captured.

     

    Max DNIS digits

    Dialed Number Identification Service (DNIS) is a service provided by telephone companies that lets the subscribers determine which telephone number was dialed by a caller.

    Enter the number of digits of a dialed call to be sent by the telephone company.

     

    Caller category

    Select the caller type.

     

    Incoming digits mode

    Select the incoming digits mode by consulting your telephone company.

     

    DMTF option

    DTMF dialing

    Select to enable dual-tone multi-frequency signaling (DTMF) dialing.

     

    DTMF answering

    Select to enable dual-tone multi-frequency signaling (DTMF) answering.

     

    Allow collect calls

    Select to allow collect calls.

  5. Click OK.
