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.
