7. To confirm correct MCUF status, at the CUST MMI prompt, enter:
state <site #> btp * *
Where <site #> is the site number.
The status of both BTPs will be displayed as follows:
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 E–U NO REASON
Where B–U is busy unlocked (master) and E-U is enabled unlocked
(redundant).
8. Reconnect the 2.048 Mbit/s link.
NOTE
There is no need to unlock the CTUs as these are
automatically unlocked during the initialization procedure.
NOTE If a PCMCIA card is not available then the firmware in the
redundant MCUF may be updated by removing the master
MCUF and placing the redundant MCUF in the master
position. Code download from the BSC will ensure the
newly installed MCUF is fully updated. This procedure
however is likely to take up to 30 minutes longer than the
procedure involving a PCMCIA card, resulting in a longer
out of service time for the BTS.
