REGISTRATION ID
There are two instances where the OLT will register the ONT:
■ Serial Number Activation (performed by the OLT when the ONT is “Discovered”)
■ Registration ID using a lineman’s handset (see below)

Set Registration ID Activation using Lineman’s Handset
To set the Registration ID using a DTMF Keypad on a standard lineman’s handset, complete the following steps:
NOTE
The ONT does not need to be connected to the OLT during the Registration ID process.
Only POTS port 1 can be used for Registration ID configuration.
1. Perform an initial power-up on a new ONT.
NOTE
At the start-up of the ONT, a 10-second Registration ID the configuration window is provided.
2. Wait for the indication that the Registration ID configuration is available.
The GPON LED will be flashing green on a 200-millisecond interval when Registration ID configuration is available.
3. Go off-hook and observe that dial tone is heard.
NOTE
Once a dial tone is heard by going off-hook during the Registration ID window, you have 10 seconds to enter the initial digits 00. Once 00 is entered, you have 300 seconds to complete the Registration ID process.
4. After a dial tone is heard, enter 001234XXXXXXXXXXXXXXXXXXXX, where XXXXXXXXXX is the Registration ID for this site.
NOTE
Only digits 0-9 are supported.
5. If entered correctly, a confirmation tone is played and the number is displayed on the phone’s caller-id display with the string “ACCEPTED”.
6. If programming is successful, the ONT plays a stutter dial tone and flashes the GPON LED green for approximately 10 seconds with a cadence of 300 milliseconds on/off before it continues its startup/ ranging process.
** NOTE
If a failure occurs, the ONT plays reorder tone and displays Invalid on the caller-id display. If the pattern is entered incorrectly, the caller id displays Re-enter* if the
the first ID does not match the second.
Entering an invalid Registration ID, such as one with less than 10 digits or non-matching values, results in a reorder tone and you have the same 10-second window to restart step 3 to allow you to re-enter codes that were entered incorrectly.
