Audio Check and
Confirmation
-
1. Link to BASE which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Input -45 dBm (600
Ω
)/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -3 dBm ± 5 dB and that the distortion level is < 5 % at
TEL Line (600
Ω
Load).
5. Input -20 dBm (600
Ω
)/1 kHz to Line I/F. Measure the Level at Receiver of
Handset and distortion level (Receive volume set to second position from
minimum).
6. Confirm that the level is -24 dBm ± 4 dB and that the distortion level is < 5 % at
Receiver (34
Ω
Load).

) SP phone Audio Check
and Confirmation
-
1. Link to Base which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Set the handset off-hook using SP-Phone key.
4. Input -30 dBm (600
Ω
)/1 KHz to Line I/F and measure Receiving level at SP+
and SP-.
5. Confirm that the level is -8 dBm ± 3 dB and that the distortion level is < 5 %.
