Please note:
During maintenance an NCI Alarm (non-CRC4 interworking) can appear. If
this alarm is active, and it is known that the other equipment now sends the
CRC4 multiframe, the following procedure can clear the alarm:
→ Perform a "Force new search" in the CRC4 MFA status of the P12
layer, or
→ Disable CRC4 and re-enable the CRC4.
Description / Details
No loop active.
Refer to section "Loops" (page 28)
The incoming signal from the E1 port is looped
back towards the E1 port.
The loop is removed when the configuration is
restored or the port administrative state is set to
down.
The outgoing signal towards the E1 port is
looped back towards the backplane.
The loop is removed when the configuration is
restored or the port administrative state is set to
down.
The CRC4 monitoring function is active.
Note that the CRC4 multiframe alignment state is
read only.
The CRC4 monitoring function is disabled due to
disabled CRC4 at the remote equipment.
If the CRC4 multiframe alignment is in the NCI
state no further automatic search is done. A new
search for CRC4 multiframe alignment must be
initiated manually with the "Force CRC4 Multi-
frame Search" command (see below).
The port is configured without CRC4 monitoring.
Trigger a new attempt for the CRC4 multiframe
alignment.
To check the result of the new attempt, you have
to press the "Refresh" button.
