Code Active in the PSTN

Per Section 4.2.1 (c) of the Thousands Block Pooling Administration Guidelines (TPBAG)
it states that the LERG Assignee shall “Verify and test that the NXX Code is activated in the
Public Switch Telephone Network (PSTN) prior to the NXX Code’s LERG Effective Date ;”.

The Pooling Administrator sends out the PSTN reminder notices starting on the effective date of the NXX Code, and continuing every 10 days until notification is received from the Service Provider that the NXX Code has been activated in the PSTN. Unfortunately submitting a Part 4 does not fulfill this requirement of PSTN verification. When receiving a PSTN notification from the Pooling Administrator with the subject line of “Confirmation of Code Activation in PSTN Reminder for NPA-NXX”, you must reply and verify that the NXX Code is now active in the PSTN in order for the PA to make the change in PAS. As a result the available blocks in PAS will change from a “Pending” (Red) status to an “Available” (Black) status and the PSTN reminders will cease for that NXX Code.
