PSC DG01 covers network support labor, and its scope is wider than the name suggests. The manual includes physical and wireless networks inside data centers and work areas, wide area network equipment connecting data centers, offices, and third parties, on-premise voice services through PBX, VoIP, voicemail, and handsets, transport services for data and voice circuits, external outside-plant physical communications infrastructure connecting to LAN and WAN end points, and mobile infrastructure such as cabled communication networks, cellular towers, repeaters, and switching systems dedicated to cellular communication. FY2025 obligations were $3.0 billion.
Cell towers under an IT code
That last clause is the one worth reading twice. Tower and repeater work sits inside a D-family IT code, not in a construction code, which means infrastructure firms searching only the C and Y series will never see it.
Where the money goes
Computer Systems Design Services (541512) took $1.17 billion, Other Computer Related Services (541519) took $452 million, Computer Facilities Management Services (541513) took $430 million, engineering services 541330 took $263 million, and 811213, Communication Equipment Repair and Maintenance, took $161 million.
The PSC describes the buy and the NAICS code describes the seller; both appear on every contract action but neither implies the other.
Pair DG01 with 7G21 to see the labor and the hardware sides of the same network programs.
