(F)* Hookswitch Check with
DC Characteristics
- 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.

<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 “ANT”.
5. Confirm that the NTP value at ANT is 14dBm ~ 20dBm.
