    The adjustment is made by number of units of 100 ms.
    Default Transmission
    YES: the external dialing is transmitted as soon as the tone is detected or after the default transmission delay.
    NO: the external dialing is transmitted as soon as the tone is detected by the DSP (trunk group seizure tone, intermediary national and international tones); if there is no tone, the system releases the trunk and takes another.

    This time-out is to be controlled if the remote exchange does not send out a battery inversion signal or a charging signal reception,
    At the end of this time-out, the outgoing call switches into "conversation" status allowing services to be taken into account (double call, transfer, conference, transparency to dialing...) and possible charging pulses.
    The adjustment is made by number of units of 100 ms.

    This will enable the remote called party to on-hook his set and pick up the call on another set in parallel.
    Wait for Caller Release Timer
    If the Caller does not go on-hook, this time-out makes it possible to control the time during which the system waits for the called party goes off-hook again before releasing the call.
    The adjustment is made by number of units of 100 ms.
    Unavailable Time Betw.2 Seizes
    This timer manages the idle duration of the trunk between 2 consecutive calls. Any incoming calls during this timer are taken into account.

    Number of Digits Received
    The Number of digits received (between 1 and 8) is the number of digits provided by the public network for the direct dialing incoming.
    If this parameter is:
  • equal to 0, DID is used in open dialing. In this case, DID transcoding cannot be used (see TRUNK GROUPS - attribute DID transcoding),
  • different from 0, the DID is used in closed dialing.

    The number of digits in the local directory can be different from the Number of digits received. This is the number of digits necessary for the system to be able to select the digit.
    The Number of digits used can contain between 1 and 8 digits.
    The default value is 3.

    MF R1 Level
    This attribute makes it possible to adapt the level to the different MF R1 frequencies (High level/low level).
    Trunk Signaling Type
    This attribute makes it possible to adapt the type of signaling for PCM interface:
  • Normal bits
  • Inverted bits

    R1.5 First Signal
    Not informed


    • Priorities
    Category of the trunk to be used for the BEMILCOM project on R2 trunks.
    It indicates whether the R2 trunks use a particular signaling to send a priority notion.
    R2 signaling: Outgoing call on R2 with priority.
    (See priority service or MLPP service).


    Voice pipe trunk
    Used if the trunk type is Voice TL Trunk.


    2280 BEMILCOM TL Trunks
    Used if the trunk type is 2280 BEMILCOM TL Trunk..


    Receiving the Dialling
    YES: the circuit is used as automatic tie-line.
    NO: the circuit is used as manual tie line.

    Delay Waiting for Reply
    Time-out after which the change over conversation is performed if the remote terminal does not transmit any answer signal. The network-to-network transfer is impossible if value = 0-0.
    The adjustment is made by number of units of 100 ms.

    Delay Between Digits on Sending
    This time-out programs the delay between each digit transmitted.
    The adjustment is made by number of units of 100 ms.

    Delay Before Outdialling
    Time-out which makes it possible to delay the transmission of the first digit after receiving the proceed to send signal. It also makes it possible to transmit by default the status code Tie line.
    The adjustment is made by number of units of 100 ms.

    Reply by Pulse
    YES: signal sent as a pulse.

    Controlled Release
    YES : the trunk is released after the signal for remote terminal release is received.

    Dial Tone Detection
    YES: an invitation to transmit tone is expected from the remote before the dialing is emitted.

    Default Transmission
    Outgoing dialing is transmitted as soon as the tone is detected by DTON (trunk seizure tone, intermediary national and international tones).
    YES: If there is no tone, outgoing dialing is transmitted after the default transmission time-out.
    NO: If there is no tone, the system releases the trunk and takes another.

    Busy Tone Connection
    YES: the busy tone is transmitted to the remote user (for example a wrong number has been dialed or the station is busy).

    Seizure Pulse Time
    Seizure pulse transmission time.
    The adjustment is made by number of units of 8 ms.

    Answer Pulse Time
    Answer pulse transmission time.
    The adjustment is made by number of units of 8 ms.

    Release Pulse Time
    Release pulse transmission time.
    The adjustment is made by number of units of 8 ms.


    Radio channel trunk
    Used if the trunk type is Radio channel trunk.
