Check
Point
CLK
1. Input Command " sendchar WWD ff 48 IC 8006"
VDD4
2. Confirm that the voltage between testpoint VDD4 and GND is less than 1.0 V.
3. Input Command " sendchar sfr", then you can confirm the current value.
4. Check X'tal Frequency. (10.368 MHz ± 100 Hz).
5. If the frequency is not 10.368MHz ± 100Hz, adjust the frequency of CLK exe-
cuting the command "sendchar sfr xx xx (where xx is the value)" so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
-
1. Connect Telephone Socket to Tel-simulator which is connected with 600 Ω.
2. Set line voltage to 48 V and line current to 40mA 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 Telephone Socket to DTMF tester. (Load=600 Ω)
2. Link Handset and push dial key.
3. Confirm DTMF character.
4. Confirm that the high Group is -3 ± 2dBm.
5. Confirm that the low Group is -6 ± 2dBm.
-
Remove the Antenna before starting step from 1 to 7.
ANTI_TP
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 19.0 dBm ~ 25.0 dBm.
-
Follow steps 1 to 6 of (J).
ANTI_TP
7.Confirm that the B-Field Modulation is -370 ± 30/ +370± 30 kHz/div & Modu-
lated width
8.Adjust the B-Field Modulation if required. (Execute the command "readmod"
and "wrtmod xx", where xx is the value.)
Procedure
690 kHz using data type Fig31.
