xStatus ISDN PRI Interface [1..1] Channel [1..n] Type
Shows the channel type for a channel on the PRI interface. the PRI interface comprises a
number of channels, each dedicated to either the primary communication or to control and
signalling information.
DChannel:
the channel is a data channel (D channel), which carries the control and
signalling information in ISDN. the bit rate of the D channel on a PRI interface is 64 kbps.
BChannel:
the channel is a bearer channel (B channel), which carries the primary video
conference or speech call communication in ISDN. the bit rate of a B channel on a PRI
interface is 64 kbps.
xStatus ISDN PRI Interface [1..1] Channel [1..n] Status
Gives information about the call progress in a channel on the PRI interface. the information
indicates the various stages each channel goes through whilst establishing a connection.
Idle:
the channel is idle. this state is normally only seen if the channel has never been used.
Calling:
the network has acknowledged an incoming call, but the connection is not yet
established.
Answering:
the network has acknowledged an outgoing call, but the connection is not yet
established.
Connect:
the connection is established.
Disconnecting:
Waiting for the network to confirm the termination of the incoming or
outgoing call.
Disconnected:
the network has acknowledged the termination of the call. the channel is
available for a new call.
xStatus ISDN PRI Interface [1..1] Channel [1..n] Call [1..n] CallingNumber

ISDN Link is making a call to on the ISDN PRI interface (for an outgoing call).
Format:
String.
xStatus ISDN PRI Interface [1..1] Channel [1..n] Call [1..n] CauseLocation
