LERG Assignee Confirmation Required For Newly Assigned Pooled NXXs

Sections 7.5.3 and 7.5.4 of the Thousands-Block Number (NXX-X) Pooling Administration
Guidelines (TBPAG) outlines the process on how the LERG Assignee and the PA would
ensure that thousands-blocks will not be made available for assignment in the industry inventory pool until the LERG Assignee has confirmed that the code has been activated in the PSTN, loaded in the NPAC, and all other LERG Assignee Responsibilities have been fulfilled for new NXX(s) opened for pool replenishment and LRN purposes:

7.5.3 Before allocating blocks from a new NXX that was assigned for use in an industry pool, the PA must verify with the LERG Assignee that the code has been activated in the PSTN, loaded in the NPAC, and all other LERG Assignee Responsibilities have been fulfilled. This step ensures that blocks allocated to other SPs will be viable except with the option below.

As an option, and at the request of a block applicant, the PA may assign a block(s) from the code with a block effective date one business day after the effective date of the code, if a block applicant communicates to the PA via email or fax that the block applicant explicitly understands that the underlying code may not yet be activated in the PSTN and loaded in the NPAC on the block effective date. Regardless of whether this option is utilized, it is still advisable for block recipients to make a test call and ensure that default routing has been established by the LERG assignee before loading the assigned blocks into translations, and to verify that the NXX has been loaded in the NPAC.

7.5.4

PA and LERG Assignee Tasks On the original Part 3 NXX effective date, PAS will automatically generate an email to the PA and to the LERG assignee asking that the LERG assignee verify that the pooled NXX has been activated. This means that the LERG assignee confirms that facilities and translations are in place and a call through test [1]was successfully performed. The LERG assignee is required to send an email response to the PA within 5 business days indicating the status of the NXX.  If the LERG assignee confirms that the NXX has been activated, the PA shall, within 2 business days, change the status of the blocks in PAS to 'available for assignment' to any SP.  If the LERG assignee fails to respond or tells the PA that the NXX has not been activated, the status of the blocks in PAS remains unchanged. PAS will continue to generate an email message to both the PA and to the LERG assignee requesting status on the NXX. This email will be sent every 10th calendar day from the original Part 3 NXX effective date.  If the LERG assignee confirms that the NXX has been activated, the PA shall, within 2 business days, change the status of the blocks in PAS to 'available for assignment' to any SP. If the LERG assignee fails to respond or tells the PA that the NXX has not been activated, the status of the blocks in PAS remains unchanged. PAS will continue to generate an email message to both the PA and LERG assignee requesting status of the NXX. This email will be sent every 10th calendar day until the LERG assignee responds to the PA or until the code is reclaimed by the CO Code Administrator.
