Point
- 1. BBIC Confirmation (Execute the command "getchk").
2. Confirm the returned checksum value.
Connection of checksum value and program number is shown below.
TP1 1. Execute the command "deactmac".
2. Execute the command "conttx".
3. Input Command "rdeeprom 00 00 02", then you can confirm the current value.
4. Adjust the frequency of TP1 executing the command "setfreq 00 xx (where xx
is the value)" so that the reading of the frequency counter is 10.368000MHz ±
10Hz.
- 1. Connect J1 (Telephone Socket) to Tel-simulator which is connected with 600
Ω.
2. Set line voltage to 48V at on-hook condition and line current to 40mA at off-
hook condition of normal telephone.
3. Execute the command "hookoff".
4. Confirm that the line current is 40mA ± 5mA.
5. Execute the command "hookon".
6. Confirm that the line current is 0mA + 2mA.
- 1. Connect J1 (Telephone Socket) to DTMF tester.
2. Execute the command "hookoff" and "dtmf_up".
3. Confirm that the high frequency (1477.06Hz) group is -3 ± 2dBm.
4. Execute the command "dtmf_lo".
5. Confirm that the low frequency (852.05Hz) group is -6 ± 2dBm.
- Remove the Antenna before starting steps from 1 to 5.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• • • • Short TP10 and GND
(After the checking, disconnect the wiring between them.)
• • • • Test mode: FP
• • • • Traffic Channel: 5
• • • • Traffic Slot: 4
• • • • Mode: Loopback
• • • • PMID: 00000
2. Execute the command "testmode".
3. Initiate connection from DECT tester. ("set up connect")
4. Execute the command "ANT 1".
5. Confirm that the NTP value at ANT is 20dBm ~ 25dBm.
ANT Follow steps 1 to 3 of (H) above.
4. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data
type Fig31.
5. Adjust the B-Field Modulation if required. (Execute the command "readmod"
and "wrtmod xx", where xx is the value.)
