(
I
) DTMF Generator Check
-
1. Connect Telephone Socket to DTMF tester. (Load=600
)
2. Link Handset and push dial key.
3. Confirm DTMF character.
4. Confirm that the high Group is -8.0 ± 2 dBm (for BL,ML) or -6.0 ± 2 dBm (for
TU,BX,UE,CX,HK,TW).
5. Confirm that the low Group is-10.5 ± 2 dBm (for BL) or -8.0 ± 2 dBm (for
TU,BX,UE,CX,HK,TW) or 10.0 ± 2 dBm (for ML).

ANTI_TP
Remove the Antenna before starting step from 1 to 7.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: FP
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• PMID: 00000
• RF LEVEL = -70 dBm.
2. Execute the command ”sendchar TST”.
3. Execute the command “sendchar dmv 2 2”.
4. Check that “Signalling Status” has been set to “Locked”, then press “ACCEPT
RFPI”.
5. Initiate connection from Dect tester (“set up connect”)
6. Execute the command “ANT1”.
7. Confirm that the NTP value at ANT is 18.5 dBm ~ 25.0 dBm.

Audio Check
-
1. Link with Handset which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Input -45 dBm (600
)/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -1.5 ± 5dBm (for BL.TU,BX,UE) or -4.0 ± 5dBm (for
HK,TW) or -0.4 ± 5dBm (for CX) or -3.5 ± 5dBm (for ML) and that the
distortion level is <5% at TEL Line (600
Load).
5. Input -20 dBm (600
)/1kHz 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 -10±3 dBm and that the distortion level is <5 % at
Receiver (34
Load).
