Determines how voice and signaling information is routed to and from the T1 or E1 trunk and DSP resources.
NetworkInterface.T1E1[x].SignalingType = type
x = 0-(n-1) (0-based trunk number or range of trunk numbers where n equals the number of trunks on the board.)

NetworkInterface.T1E1[0..7].SignalingType = CAS
The switch model for the board changes based on the NetworkInterface.T1E1[x].SignalingType setting.
NetworkInterface.T1E1[x].SignalingType can be set to any of the following values:
This value... |
Makes settings appropriate for... |
---|---|
CAS |
Channel associated signaling. This is the default value. |
PRI |
Primary-rate ISDN. There are 30 bearer channels for E1 and 23 bearer channels for T1. |
RAW |
Primary-rate ISDN with no signaling information (that is, no D channel). Connects all channels as voice channels (B channels) and turns off robbed bit signaling. There are 31 bearer channels for E1 and 24 bearer channels for T1. |
NetworkInterface.T1E1[x].SignalingType is required for ISDN configurations. If no NetworkInterface.T1E1[x].SignalingType statement is provided in ISDN configurations, an ISDN_BAD_NAI error can be returned, even if the NAI statement is correct.
