ROTL RESPONSE
SENT TO ROTL a
TO COMMAND a
MEANING
Release or recycle
Test progress tone
Normal, trunk release, ready for new priming at
end of test progress tone.
60-IPM low tone (busy)
A supervisory hit or disconnect was detected on
the trunk under test during testing. (A recycle
command is normally sent by CAROT to recycle
ROTL after this response is receive.)
Release make busy
Test progress tone
Normal, trunk make busy, ready for new priming
at end of test progress tone.
120-IPM low tone
No authorization to remove
(reorder)
trunks (security callback not
performed).
60 IPM (busy}
Could not busy trunk, probably due to AML being
exceeded.
Silence
A recycle authorization sent by CAROT. ROTL
will return 60 IPM indicating that a hit or
disconnect was detected on the trunk under test.
A second recycle is required to recycle ROTL.
Notes:
a.
There is no monitoring for supervisory hits or disconnects on 102-type tests, or on connection appraisal. At any time,
ROTL sends 120-IPM low tone (reorder) to CAROT; there may be additional information available from ROTL. This
information can be requested by sending a ring forward request (1300 Hz for 100 ms). Ring forward is not used by the
5ESS
®
-2000 switch ROTL in normal testing as it does not perform operational tests. The response to ring forward will
be in the guard-data-guard format. An alternative is to request a noise measurement. It will also trigger the
guard-data-guard reply, which can be interpreted as a noise reading and converted to the error code. Table 7-5 lists
the 5ESS-2000 switch ROTL errors.

Notes:
a.
The noise readings are taken using either the 92A or H310 test sets, the two common test sets used for ROTL. The
H310 test set is only capable of determining the ring forward error by making a noise measurement. The error reply is
converted into an equivalent noise reading in dB. The 92A test set can make the noise measurement, or it has
provisions for measuring the duration of the error tone directly in milliseconds.
