Point
- 1. Connect TIP/RING (Telephone Socket) to Tel-simulator which is connected
with 600 Ω.
2. Set line voltage to 48 V and line current to 40 mA at off-hook condition of nor-
mal telephone.
3. Execute the command "hookoff"
4. Confirm that the line current is 40 mA ± 5 mA.
5. Execute the command "hookon".
6. Confirm that the line current is less than + 0.8 mA.
1. Connect TIP/RING (Telephone Socket) to DTMF tester. (Road=600 Ω)
-
2. Link cordless handset and push dial key.
3. Confirm DTMF character.
4. Confirm that the high Group is -6 dBm ± 2 dBm.
5. Confirm that the low Group is -8 dBm ± 2 dBm.
ANT2 Remove the Antenna before starting step from 1 to 7.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: FP
• Traffic Carrier: 2
• Traffic Slot: 4
• Mode: Loopback
• PMID: 00000
• RF LEVEL = -70 dBm.
2. Execute the command "testmode".
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 "ANT2".
7. Confirm that the NTP value at ANT is 16.5 dBm ~ 20.5 dBm.
ANT2 Follow steps 1 to 6 of (K).
7.Confirm that the B-Field Modulation is -430 ~ -350/+350 ~ +430 kHz/div using
data type Fig31.
ANT2 Follow steps 1 to 6 of (K).
7.Confirm that the frequency offset is < ± 10 kHz.
ANT2 Follow steps 1 to 6 of (K).
7.Confirm that the frequency drift is < ± 20 kHz/ms.
ANT2 Follow steps 1 to 6 of (K).
7.Set DECT tester power to -88 dBm.
8.Confirm that the BER is < 1000 ppm.
ANT2 (Through Cordless handset)
Follow steps 1 to 6 of (K).
7.Confirm that the Timing accuracy is < ± 2.0 ppm.
ANT2 Follow steps 1 to 6 of (K).
7.Execute the command "readrssi".
8. Confirm that the returned value is 22 ± A (hex).
