Details

If NetworkInterface.T1E1[x].D_Channel = ISDN for any of the trunks on a board, a configuration message is sent to the ISDN stack on that board to initialize that stack. You must initialize the ISDN stack for any trunk that has a D channel. You must also enable the HDLC controller for that trunk by setting the NetworkInterface.T1E1[x].SignalingType keyword to the value PRI.

In the case of an NFAS group with a backup D channel, specify this keyword for the primary D channel only. The backup D channel is specified using the NetworkInterface.T1E1[x].ISDN.D_Channel_Backup_Trunk keyword.

NetworkInterface.T1E1[x].D_Channel is required in any configuration where NFAS is used. For information about NFAS groups, refer to the Dialogic® NaturalAccess™ ISDN Software Installation Manual.
