Contents Introduction
xStatus ISDN PRI Interface [1..1] BChansTotal
Shows how many B channels (bearer channels, 64 kbps) the PRI interface offers in total.
Value space of the result returned:
<1..30>
Example:
xStatus ISDN PRI Interface 1 BChansTotal
*s ISDN PRI Interface 1 BChansTotal: 30
** end
xStatus ISDN PRI Interface [1..1] Layer1Status
Shows whether there are issues relating to framing information (physical layer).
Sync: The system is receiving framing information and the channels are synchronized.
Yellow: The system is receiving framing information, but the remote system is not receiving the
transmitted framing information. This may be caused by a broken connector in the TX part of your PRI
cable. It could also indicate a weak or noisy signal in the TX part of the PRI cable.
Red: There is no signal and thus the system receives no framing information from the remote site (this
has the same effect as pulling out the PRI cable).
Blue: The network on the far side of the CSU (Channel Services Unit) is unavailable. For example,
assume that a system is connected via a CSU (Channel Services Unit) as follows: System–CableA–
CSU–CableB–Network. If the CSU loses framing/synchronisation from the network, e.g. due to a bad
CableB, it will no longer send valid framing out on CableA towards the system. Instead it transmits
"Blue Alarm". Seen from the system receiving the blue alarm, this means that the network on the far
side of the CSU is unavailable.
Unknown: The system is not able to determine the layer 1 status.
Value space of the result returned:
<Sync/Yellow/Red/Blue/Unknown>
Example:
xStatus ISDN PRI Interface 1 Layer1Status
*s ISDN PRI Interface 1 Layer1Status: Sync

xCommand
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.
Value space of the result returned:
<DChannel/BChannel>
Example:
xStatus ISDN PRI Interface 1 Channel 1 Type
*s ISDN PRI Interface 1 Channel 1 Type: BChannel
** end
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.
Value space of the result returned:
<Idle/Calling/Answering/Connect/Disconnecting/Disconnected>
Example:
xStatus ISDN PRI Interface 1 Channel 1 Status
*s ISDN PRI Interface 1 Channel 1 Status: Idle
** end
Shows the number calling into the ISDN PRI interface (for an incoming call), and the number that ISDN
Link is making a call to on the ISDN PRI interface (for an outgoing call).
Value space of the result returned:
<String>
Example:
xStatus ISDN PRI Interface 1 Channel 1 Call 20 CallingNumber
*s ISDN PRI Interface 1 Channel 1 Call 20 CallingNumber: "1234"
