Glenshaw switch retirement moves Verizon traffic to Oakland

Verizon plans to retire and remove the Glenshaw 5ESS telephone switch at 1003 Charles Street after traffic is migrated to its Oakland PA CS2K switch at 530 N. Neville Street in Pittsburgh. The company’s June 3, 2026, public notice lists an implementation date on or after July 29, 2026.

As of July 31, Verizon’s documents establish the planned migration window, but they do not independently confirm that the Glenshaw equipment has already been physically removed. The change is primarily a network-routing action affecting carrier interconnections, not an announcement that Glenshaw residents will automatically lose telephone service.

Traffic will be routed through Oakland

Verizon says traffic handled through the Glenshaw 5ESS switch will be migrated to the Oakland switch. The affected categories include inter-LATA traffic, access traffic, competitive-local-exchange carrier traffic, interexchange carrier traffic, wireless traffic and paging traffic.

In plain language, a central-office switch directs calls and other telecommunications traffic between networks. Retiring the Glenshaw switch changes where that routing takes place. It does not, by itself, establish that a retail telephone plan, wireless service, broadband connection or paging service is being discontinued.

Four Glenshaw codes will be rehomed

A Verizon Partner Solutions industry letter identifies four 412 exchange codes associated with the Glenshaw switch: 486, 487, 492 and 961. Verizon says those codes will be rehomed to the Oakland switch and reflected in the Local Exchange Routing Guide after the Glenshaw switch is decommissioned.

The codes are technical routing identifiers, not four retail exchanges being closed. Their reassignment matters to telecommunications companies because it tells interconnected networks where calls destined for those numbers should be delivered.

Carriers face technical work

Competitive local exchange carriers, interexchange carriers, wireless carriers and paging carriers were directed to establish new trunk groups to Oakland or augment existing ones. Verizon’s notice also says access-service code holders must reposition their codes to the Oakland switch.

The industry letter gives July 29, 2026, as the migration deadline, while the public notice describes the retirement as occurring on or after that date. Those documents define Verizon’s implementation schedule; the materials supplied for this report do not provide separate confirmation that every migration step or the physical switch removal has been completed.

What the filing does and does not establish

The FCC’s technology-transition order provides context for distinguishing a network-change filing from a retail-service discontinuance. Verizon’s Glenshaw notice describes the retirement of network equipment and the movement of traffic between switches. It does not document that residential telephone service is being discontinued.

The notice also does not document a residential service outage, a copper-line retirement, a broadband shutdown, a change to 911 service or a change to wireless coverage. Residents who experience a problem should contact Verizon or their own service provider for account-specific information rather than assuming the switch notice means service has ended.

Bottom line for Glenshaw

For Glenshaw, the practical significance is that a long-standing piece of Verizon network equipment is scheduled for retirement and its traffic is being redirected to Oakland in Pittsburgh. The immediate work described in the filings falls mainly on carriers and other telecommunications companies responsible for maintaining their interconnections during the transition.

The filing confirms a network-routing change, but it does not establish that every Verizon customer in the Glenshaw area will be affected or that residential, wireless, paging, broadband or emergency service has ended.
