PLEASE NOTE:

• All references to the Fairfax VA CS2K switch are associated with CLLI code FRFXVAFFPS0 and will not be repeated throughout the notice.
• All references to the Fairfax VA C20 switch are associated with CLLI code FRFXVAFFPS1 and will not be repeated throughout the notice.

Description of the Planned Network Change(s):

The Verizon Fairfax VA CS2K switch, located at 10431 Fairfax Boulevard, Fairfax, VA 22030, will be retired and removed from the Verizon network after all traffic served by this switch is migrated to the Verizon Fairfax VA C20 switch, located at 10431 Fairfax Boulevard, Fairfax, VA 22030. All traffic to be migrated to the Fairfax VA C20 switch includes, but is not limited to, Inter-LATA (ACCESS/FG-B-D/CLEC IXC), wireless and paging traffic.

Description of Reasonably Foreseeable Impact(s) of the Planned Change(s):

All carriers, including competitive local exchange carriers (CLECs), Interexchange carriers (IXCs, IECs), wireless carriers, and paging carriers, will need to provision new trunk groups to support direct end office trunking to the Fairfax VA C20 switch or have existing trunk groups to that switch augmented.

All ASRs for the Fairfax VA C20 switch must be received no later than September 1, 2025, to provide sufficient time to migrate the traffic described above. Local Exchange Routing Guide (LERG) change effective dates will be posted prior to decommissioning of the Fairfax VA CS2K switch (on or after October 25, 2025). This will serve to guide interconnect re-routes of traffic for the Number Plan Area (NPA) codes currently served by the Fairfax VA CS2K switch to reflect the Fairfax VA C20 switch as the new home switch. All trunks to the Fairfax VA C20 switch must be in place prior to the decommissioning of the Fairfax VA CS2K switch.
