Use the NetworkInterface.T1E1[x].SignalingType (where x is the number of a trunk) keyword to configure routing of voice and signaling information between trunks and DSPs. Set this keyword as follows:
If you are not setting up NFAS groups, set NetworkInterface.T1E1[x].SignalingType to PRI (or BRI, if applicable) for each board in your system. This setting routes D channel information on each trunk to the HDLC controllers and routes B channel information to DSP resources.
If you are setting up NFAS groups, set NetworkInterface.T1E1[x].SignalingType as follows:

Set NetworkInterface.T1E1[x].SignalingType to... |

PRI or BRI. This setting routes D channel information on the trunk to the HDLC controllers and routes B channel information to DSP resources. |
|

RAW. This setting routes B channel information only. |
If MVIP switching is enabled, routing does not take place regardless of the NetworkInterface.T1E1[x].SignalingType setting. Instead, your application must make the appropriate MVIP switch settings, as described in the NMS ISDN for Natural Call Control Developer's Manual and NMS ISDN Messaging API Developer's Reference Manual.
