To set the Registration ID using a DTMF Keypad on a standard lineman’s
handset, complete the following steps:
1. Verify the PON fiber-feed is disconnected from the ONT.
2. Press the RESET button on a previously powered-up ONT, or perform
an initial power-up on a new ONT.
3. Wait approximately one minute for the start-up to complete, (PWR LED
is ON and solid; FAIL LED is ON and solid).
4. Attach the handset to the POTS Port 1 and go off-hook.
5. Observe that the reorder tone (fast busy) is generated.
NOTE
The Reorder tone is continuously played after going off-hook until the valid
Registration ID password is dialed. See Step 6.
6. On the keypad, dial the registration ID password: *123#.
7. Observe that the special information tone is generated.
NOTE
This is a fast “Hi-Mid--Low” tone that repeats.
