PSC 7G21 covers digital network products. The manual's list is broad: hardware, software, and equipment used inside core data centers and work areas, LAN and WAN digital transmission equipment connecting data centers, offices, and third parties, external outside-plant infrastructure connecting LAN and WAN endpoints, copper and fiber communications systems, cellular infrastructure such as towers, repeaters, and switching systems, and on-premise digital voice equipment including PBX, VoIP, voicemail, and handsets. FY2025 obligations were $909 million.
Half the code is channel
541519, Other Computer Related Services, took $452 million, right at 50 percent. The manufacturers split the rest: Other Communications Equipment Manufacturing (334290) at $116 million, Telephone Apparatus Manufacturing (334210) at $90 million, Electronic Computer Manufacturing (334111) at $70 million, and 541512 at $68 million. That is the standard shape of federal network hardware buying, where a value-added reseller holds the vehicle and the OEM sits behind it.
PSC and NAICS in one line
A PSC records the requirement, a NAICS code records the vendor's industry, and a reseller-heavy top five means the two rarely agree on product codes.
Cellular towers appear in both 7G21 and DG01, the network support labor code. If you build or maintain wireless infrastructure, run both searches: the equipment and the labor are coded separately.

Frequently Asked
PSC 7G21 questions, answered.
What does PSC 7G21 cover?
Digital network products: LAN and WAN transmission equipment, outside plant infrastructure, copper and fiber systems, cellular towers, repeaters and switching systems, and on-premise digital voice equipment including VoIP and PBX.
What NAICS codes win 7G21 work?
541519 took $452 million, half of $909 million, with Other Communications Equipment Manufacturing (334290) at $116 million and Telephone Apparatus Manufacturing (334210) at $90 million leading the manufacturer side.
Is cellular infrastructure a product code or a service code?
Both. The equipment is 7G21 and the support labor is DG01. The manual names towers, repeaters, and switching systems in each.
How does 7G21 differ from 7G20?
7G21 is digital. 7G20 is the legacy analog voice equivalent, covering analog transmission, copper plant, and analog PBX and handsets.
