Troubleshooting: If Telephone line type Screen Appears
The telephone line type may not be identified correctly when connection is made to an ADSL line, optical line, or control device such as a PBX (private branch exchange).
Follow the steps below to set the same line type (Touch tone, Rotary pulse 20 PPS, or Rotary pulse 10 PPS) as you are subscribed to.
-
Select whether you hear beeps/boops (signal tones) when you dial from your telephone.
If you hear signal tones:
Select Touch tone, and then press the OK button.
If you do not hear signal tones:
Make sure Rotary pulse is selected, and then press OK button and proceed to Step 2.
-
Select same dial speed as line type you are subscribed to (Rotary pulse only).
20 PPS:
Make sure 20 PPS is selected, and then press OK button.
10 PPS:
Select 10 PPS, and then press OK button.
