Frequency Tag Protocol Functional Specification (WCI # 16803) for details. An exception to
that Protocal is that this IRD only allows for Tag Site designations from 0 to 15 inclusive, and
‘15’ is specially reserved (see next). To reduce processing overhead, the unit only looks for tags
while in the Get Tag sub-mode or when tag_testing. The IRD does not provide an indication of
time-since-last-tag.
Exceptions to the normal operation with respect to Carrier ID Tagging are:
1) If the IRD is in the nonvolatile ‘ISOG E’ state (see ‘ISOG’ terminal command), the Carrier
Tags are not required. When in the GET CARRIER submode, and Carrier Lock is achieved,
then the unit state transitions directly to TRACKING (passes through GET TAG).
2) If the Carrier Setting shows Tag Site ‘15’, then that is treated as an ‘ISOG E’ command
which is only effective as long as the IRD remains tuned to that Carrier Setting.
