Control Panel > CHANNEL STATUS ISDN-PRI AND ISDN-PRI
Buttons > Channel Status gives information about the call progress. The information indicates the various stages each
ISDN B-channel goes through whilst establishing a connection.
DIAGNOSTICS
BRI STATUS:
Idle - The channel is idle.
Calling - When calling, the network has acknowledged the call.
Connected - When connection is established.
Sync - When the channels are synchronized.
Active - When all available channels are connected.
Releasing - Waiting for the network to confirm a release of the call.
Released - When disconnected - the network has acknowledged the disconnection.
PRI ALARMS:
PRI RED ALARM: Red alarm or Loss of signal (LOS) means that there is no signal and thus no framing
information received (this has the same effect as pulling out the PRI cable).
PRI YELLOW ALARM: Yellow alarm or Remote Alarm Indicator (RAI) means that the system is receiving
framing info, but in this framing info the other side tells the system that it is not reading the system's
transmitted framing info. Typically, this may be a broken connector in the TX part of the system PRI cable.
This could also indicate weak or noisy signal in the TX part of the system PRI cable.
PRI BLUE ALARM: Blue alarm means that the network on the far side of the CSU is unavailable.
PRI Blue Alarm Example: The system is connected via a CSU (Channel Services Unit) as follows: System–
CableA–CSU–CableB–Network. If a CSU loses framing/sync from the network (example: 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.
Control Panel > CALL STATUS
Buttons > The Call status page gives information about the on-going calls.
DIAGNOSTICS The menu has two columns, one for transmitted and one for received audio/video/data information.
If Dual Stream or MultiSite is available on your system, and in use, pressing the Up/Down keys on remote
control will show one page per connected site.
Information will vary depending on whether H.320 (ISDN) calls or H.323 (IP) calls are made.
