PRIの設定方法

    Please read How do I configure TDM cards? (Analog/PRI/BRI) for step-by-step instructions on accessing the cards page and making changes.

    The most common North American PRI settings are...

    1. switchtype = national (ni2 or national 2)
    2. signalling = PRI_CPE
    3. encoding = b8zs
    4. framing = esf
    5. bchan = 1-23
    6. dchan = 24
    7. DNIS = 10 digits (however, the trixbox Pro automatically adjusts to the carrier's DNIS setting)

    What you need before you install a PRI

    1. A "cut sheet" from your carrier.  This is typically a piece of paper with the configuration information of the PRI listed.  Please obtain a cut sheet from your carrier before you attempt to install a PRI and before you contact Fonality Support.  Fonality does not know the settings for your PRI.
    2. A physical connection between the Smart Jack (owned by the carrier) and your trixbox Pro .  Every trixbox Pro containing a Sangoma PRI card should come with the proper cable.  For reference - you will be using a cross-over cable.
    3. A "Super Looper" or "Loopback Adapter".  Fonality ships all systems with this adapter in the "accessories" box.  If you have lost or misplaced the Super Looper, you can buy one at Radio Shack for a few dollars.  The Super Looper tests to make sure the Sangoma PRI card is installed and configured correctly.

    If the "most common" settings don't apply...

    Fonality supports nearly every signalling type for any implementation of ISDN (PRI) technology.  The following is a comprehensive list of all the various configuration settings Fonality supports:

    1. Framing:
      1. ESF
      2. D4
      3. CAS
      4. CCS
    2. Encoding:
      1. B8ZS
      2. AMI
      3. HDB3
      4. NCRC2
    3. Signalling:
      1. pri_cpe
      2. pri_net
      3. fxs_ks
      4. fxs_ls
      5. fxs_gs
      6. fxo_ks
      7. fxo_ls
      8. fxo_gs
      9. em (E&M)
      10. em_w (E&M Wink)
      11. em_e1
    4. Switchtype:
      1. national ni2 (national 2)
      2. national ni1 (national 1)
      3. dms100
      4. 4ess
      5. 5ess
    5. D-Channel:
      1. dchan=0
      2. dchan=24 (add 24 to this value for each sequential PRI)
      3. dchan=16 (add 16 to this value for each sequential E1)
    6. Timing:
      1. TE_CLOCK = MASTER (Timing provided by the PRI card itself)
      2. TE_CLOCK = NORMAL (Timing provided by the PRI Provider's equipment)
    7. J1 settings (for Japanese PRIs - please consult your provider for more information)
    8. BRI settings (for ISDN circuits found throughout Europe, Australia and Africa)

    If your cut sheet contains any of the above terms - don't worry - we've got you covered.
