(D)* BBIC Clock Adjustment
(Important)
P1.0
CLK
1. Execute the command “EnableClockOutput”.
2. Input Command “GetFreq”, then you can confirm the current value.
3. Check X’tal Frequency. (10.368 MHz ± 100 Hz).
4. If the frequency is not 10.368MHz ± 100Hz, adjust the frequency of CLK
executing the command “setfreq 04 xx (where xx is the value)” so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.

(E)* Hookswitch Check with
DC Characteristics
-
1. Connect J1 (Telephone Socket) to Tel-simulator which is connected with 600
.
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.

Confirmation
-
Remove the Antenna before starting steps from 1 to 5.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• 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 “ANT2”.
5. Confirm that the NTP value at ANT is 19dBm~25dBm.
