NetworkInterface.T1E1[x].D_Channel
Syntax
- NetworkInterface.T1E1[x].D_Channel = setting
- x = 0..3 (0-based trunk number or range of trunk numbers)
Access
- Read/Write
Type
- String
Default
- ISDN_NONE
Allowed Values
- ISDN | ISDN_NONE
Example
- NetworkInterface.T1E1[0..3].D_Channel = ISDN
Description
- Specifies whether the trunk has a primary D Channel with ISDN running on it. If NetworkInterface.T1E1[x].D_Channel is set to 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 NetworkInterface.T1E1[x].ISDN.D_Channel_Backup_Trunk keyword.
- NetworkInterface.T1E1[x].D_Channel is required in any configuration where NFAS is used. For more information about NFAS groups, refer to the NMS ISDN Installation Manual.
