Thousands-Blocks Donations and helpful
As a reminder, when you donate thousands-blocks via the
Appendix 2, Thousands-Block
Donation form after the block donation date, you should complete
the tasks outlined in s
ection 7.2.7 of the Thousands-Block Number (NXX-X) Pooling
(TBPAG), (below is an excerpt from that section):
As a block holder you should complete the following per
section 4.4.i per the TBPAG:
- If block donations are submitted using Appendix 2
via PAS, the PA shall process the donation within 7
calendar days. If donations are submitted by any other
method, the PA has an additional two business days for
- For any donations from a non-pooled NXX, the AOCN is
responsible for entering its specified routing and
rating information for those retained thousands-blocks.
The retained thousands-block will not appear in the LERG
Routing Guide until the AOCN has performed this task.
- For any subsequent donations of previously retained
blocks from a pooled NXX, the block(s) to be donated
must be disconnected by the AOCN in BIRRDS before
donation. An SP should use the Other Information section
in Appendix 2 if block(s) donated have any special
status or treatment, e.g., restricted use, chatline,
- Intra-SP porting of all unavailable TNs within all
thousands-blocks that are being donated to the industry
inventory pool by SPs is to be completed by the Block
4.4.i Block Holders Responsibilities
- Verify in the NPAC which TNs are
assigned in any contaminated thousands-block received
from the PA to avoid duplicate TN assignments. The
preferred method of contaminated TN verification relies
on NPAC, but use of one's own LSMS (Local Service
Management System) is also acceptable.
Below are some helpful hints:
As a reminder, the following changes were made to the
donation process due to the implementation of Change Order #51:
- When a previously donated block changes from
contaminated to non-contaminated, if possible, notify
the PA, so we can update our records accordingly.
- If you donated a block that is over 10%
contaminated, notify the PA immediately so that action
can be taken to remove the block from the inventory.
- Updating the NRUF does not update the contamination
status in PAS, please notify the PA if the contamination
- Please ensure that the Intra-SP ports are completed
prior to donating contaminated blocks, unless the newly
established pool criteria apply.
Three new fields have been added to the Appendix 2 form in PAS:
“If Contaminated, How Many TNs Are Not Available for
If a SP donates a block that is contaminated, they will be
required to enter the number of TNs that are not available for
assignment. If the SP indicates that more than 100 TNs are
unavailable for assignment, the PA will reject the donation.
“Have All IntraSP Ports Been Completed?
Per Section 7.2.5 of the TBPAG if a SP donates a block for a *newly
on or before the Block Donation
Identification Date and enters an “N” for “Have All IntraSP
Ports been completed?, the PA will be able to conditionally
accept the donation. SPs must modify the conditional donation by
changing the “N” to a “Y” on or before the block donation date,
to indicate that all of the IntraSP ports have been completed.
If the SP fails to update the conditional donation by the block
donation date, the PA will reject the donation.
If a SP donates a block for a new or existing pool after the
Block Donation date, and enters “N” in this field, the PA will
reject the donation.

status of multiple rate centers that were previously Excluded

“Has the Block Been Protected from Further Assignment?”
If the SP enters “N” in this field, the PA will reject the
