Adjustment
(Important)
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.

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 nomal 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.
