7. Use the rtrv-oc3/set-oc3 command at the host OC-12 shelf
to verify/set application (
app
) parameter for the OC-12
FUNCTION UNITS
slots being used for this OC-3 linear
extension. For example, set-oc3:fn-a,app=
1+1
.
8. Use the rtrv-oc3/set-oc3 command at the remote
FiberReach OC-3 shelf to verify/set application (
dcc
) parameter
for the OC-3
MAIN
slots being used for this OC-3 linear extension.
For example,
set-oc3:main-1,dcc=

NOTE:
If line timing mode is specified or external timing mode is
specified but the timing reference was not available at the
host OC-12 shelf turnup, the
TGS/TG3
option switches are
probably set for
free running
. Before this configuration is
established, the specified timing mode must be set on the
TGS/TG3
circuit packs.
NOTE:
If the option switch setting is changed, an update must be
done by momentarily depressing the
UPD/INIT
button on the
SYSCTL
after the
TGS/TG3
circuit packs are reinstalled.
NOTE:
SYSCTL
after the
TGS/TG3
circuit packs are reinstalled.
NOTE:
If external timing is selected and the
NE ACTY
LED remains
lighted after the
TGS/TG3
circuit pack is reinserted, use the
CIT and the rtrv-sync: command to check the
operational mode of the system. If the mode is Holdover
instead of External, check that the incoming timing
references are connected. Also check Mode Switching
(revertive or nonrevertive) and the external DS1 Line
Code/Format switch settings.
