This field specifies extensions assigned to receive tie-trunk calls from other
switches that have test line origination capability. The system responds by
sending a sequence of test tones. Test type 100 tests far-end to near-end
loss and C-message by sending:
5.5 seconds of 1004-Hz tone at 0 dB
Quiet until disconnect; disconnect is forced after 1 minute
Test Type 102 tests far-end to near-end loss by sending:
9 seconds of 1004-Hz tone at 0 dB
1 second of quiet
This cycle is repeated until disconnect; disconnect is forced after 24
hours.
Test Type 105 tests 2-way loss, gain slope, and C-message and C-notch
noise by sending:
9 seconds of 1004-Hz tone at -16 dB
1 second of quiet
9 seconds of 404-Hz tone at -16 dB
1 second of quiet
9 seconds of 2804-Hz tone at -16 dB

½ second of 2225-Hz test progress tone
approximately 5 seconds of quiet
