ISDN trunk interconnection

2N® BRI Gateway settings

  1. Set BRI gateway as NT device. Then set the mode. If you are using DDI, then set PTP (Point to Point). If you are using MSN numbers, then set PtMP (Point to multipoint). If you don't know, which mode should be selected, in 95% cases is correct Point to Point.
  2. (Optional) To avoid synchronization issue is recommended to use 2N® BRI Enterprise and connect second ISDN port of gateway to UA (Universal Alcatel) via S0 Adapter EU. Then assign to the UA some extension number to provide clock to the gateway and set TE Mode to External Sync in gateway's ISDN Parameters.
