NOTE:
If line timing mode is specified or external timing mode is
specified but the timing reference was not available at the
OC-3 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:
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.
Set timing mode on DDM-2000 TGS/TG3 circuit packs to the
timing mode specified in work order or office records.

NOTE:
If Kbyte or Sbyte (sync messaging) is enabled for the OC-3
or OC-12 main-1 and main-2 optical interfaces at any
node in the OC-3 or OC-12 ring, it must be enabled at all
nodes in the OC-3 or OC-12 ring.
NOTE:
The rtrv-oc3: or rtrv-oc12: command retrieves the
OC-3 Line Provisioning Report or
OC-12 Line Provisioning Report. This report
displays the provisioned configuration of OC-3 or OC-12
lines. See the Commands and Reports section of this
manual for a description of the rtrv-oc3: or rtrv-oc12:
command format.
