8.7.1 Functions and appearance

Panel
The TEST is a voice service test card for the common telephone and magneto telephone. It
provides the following functions:
 Support 4 voice interfaces. Each voice interface can work as a test end which can test 1
TEST
way of voice services on three-way calling, bidirectional monitoring, and audio test. In
PWR SYS
other words, the TEST card supports testing 4 ways of voice services concurrently.
 Provide two FXS interfaces and 2 MT interfaces. Every 2 voice interfaces use 1 voice
module. Every 2 FXS interfaces use 1 voice module. Every 2 MT interfaces use 1 voice
MT FXS
module.

 Support the voice signaling test: No. 1 and No. 2 voice interfaces support sending ring
M2
current to the telephone or sending signaling to the PBX for the signaling test. No. 3 and
No. 4 voice interfaces supports sending ring current of common ring or 2100 MHz
magneto ring.

Support the voice call test: the test end performs a two-way/three-way call with one or two
ends of tested voice services. The two-way call is applicable to the test from the test end to
the local device, or test end to the remote device. The three-way call is applicable to the
test among the test end, local device, and remote device.

Support the audio sending test: send audio signals to one or two ends of tested voice
services. It also supports sending the frequency and level of audio signals. Configured
parameters of frequency and level of audio signals take effect on all test ends. Audio
signals support 11 types of frequency (700 Hz, 775 Hz, 800 Hz, 825 Hz, 900 Hz, 2000 Hz,
2075 Hz, 2100 Hz, 2125 Hz, 2200 Hz, and 2600 Hz, and 6 types of level (0 dBm, -4 dBm,
-8 dBm, -12 dBm, -18 dBm, and -22 dBm).

Support the voice monitoring test: the test end monitors both parties' call of tested voice
services. The two parties can call normally while the test end can only monitor the call.
 Support the voice timeslot loopback test: configure timeslot loopback on one or two ends
IN-USE
of tested voice services.

 The voice interface and ring current output support overcurrent protection.
 The magneto telephone supports detecting and generating the 2100 Hz audio.
 Support online upgrade.

Rx (A/D) gain of FXS/FXO/ and magneto telephone ranges from -10 to 16 dB. By
default, it is 0 dB.
FXS/FXO Tx (D/A) gain ranges from -13 to 10 dB. By default, it is -3.5 dB.
Magneto telephone Tx (D/A) gain ranges from -17 to 8 dB. By default, it is -3.5 dB.
The TEST (B) must be used with the RC3000-15-DXC (F.00 or later). Only one
TEST (B) can be inserted into a RC3000-15.
