Notes:
a. Refer to XXX-BD (Common Port Circuit Pack) Maintenance documentation
for descriptions of these tests.
b. Refer to TONE-BD (Tone-Clock Circuit Pack) section for descriptions of
these tests.
c. Refer to TDM-CLK (TDM Bus Clock) section for descriptions of these tests.
d. This test only runs on the Standby Tone-Clock circuit pack in a Port
Network with more than one Tone-Clock circuit pack (High or Critical
Reliability Option). The circuit pack must be a TN780 code with firmware
revision 2 or above, or a TN2182.
Tone Generator Transmission Test (#40)
The purpose of this test is to verify that the tone generation hardware on the
tone-clock circuit pack is capable of generating a subset of system tones and a
set of test tones. This test does not verify all system tones the tone generator
produces during normal system operation.
The test is performed in two parts. For the first part, the Tone Generator is told to
generate the touch-tone digits. The digits are received and checked by a Tone
