Status information Status information
Shows the status of the PRI interface.
Ready: the PRI interface is ready to relay calls.
NotReady: the PRI interface is not ready for use, e.g. when synchronization is missing or the
line is broken.
Off: the PRI interface is not enabled (i.e. xConfiguration H320 Nettype is not set to PRI).
Shows the number of B channels (bearer channels, 64 kbps) currently available on the PRI
interface.
Format:
Integer between 0 and 30.
Shows how many B channels (bearer channels, 64 kbps) the PRI interface offers in total.
Format: Integer between 1 and 30.
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.
