Action
Operate a lockout on mapper Gx by entering:
↵
lockout op <gx>
↵
yes
where
<gx> is the number of the working mapper (g1 to g4)
DS3 traffic transfers from mapper P to mapper Gx and is running error free.
The user interface protection screen indicates an asterisk (*) under the Lckt
switch field (Gx) and a request (R) replaces the asterisk (*) in the Forced
switch field (Gx). The mapper Gx active LED is ON.
Release the lockout on mapper G1 by entering:
↵
lockout re <gx>
↵
yes
where
<gx> is the number of the working mapper (g1 to g4)
Traffic transfers to mapper P and is running error free. The user interface
protection indicates a period (.) instead of an asterisk (*) in the Lckt switch
field (Gx) and the request (R) in the Forced switch field is replaced by an
asterisk (*).
Release the manual switch by entering:
↵
manual re <gx >
↵
yes
where
<gx> is the number of the working mapper (g1 to g4)

Manual switch field (Gx). DS3 continuity is maintained.
