UNSPSC 43222627: Integrated services digital network ISDN access devices

A client device providing ISDN digital transmission over ordinary telephone copper wire as well as over other media. ISDN requires adapters at both ends of the transmission so your access provider also needs an ISDN adapter. Equipment used to adapt Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) channels to existing terminal equipment standards such as EIA-232 and V.35.

A Terminal Adaptor is typically packaged like a modem, either as a stand-alone unit or as an interface card that plugs into a computer or other communications equipment (such as a router or PBX).A Terminal Adaptor does not interoperate with a modem; it replaces it.

UNSPSC 43222627 Integrated Services Digital Network (ISDN) Access Devices is a Commodity code. The recent state and local procurement activity posted under this code shows a significant mismatch: the opportunities are overwhelmingly for enterprise network switching, routing, and infrastructure equipment — including managed switches, firewalls, routers, wireless access points, and related professional services — rather than for legacy ISDN terminal adapters or access devices. The solicitations span counties (Gwinnett County, Georgia; Bergen County and Bergen Community College, New Jersey; Chatham County, Georgia), cities (Orlando, Atlanta, Philadelphia, Ocala, Tucson, Palo Alto, Eugene), school districts (Garland Independent School District, Texas; Pinellas County, Florida; Northside Independent School District, Texas), and state departments (Texas, California, Georgia), with activity concentrated in Georgia, Texas, Florida, and California over the past six months. Representative recent opportunities include Gwinnett County Board of Commissioners' October 2026 RFQ for file servers and peripheral equipment through HP resellers (response due October 29, 2026), the City of Orlando's October 2026 RFP for converged network system design and installation at Camping World Stadium with Wi-Fi 7 infrastructure (response due October 20, 2026), and Jackson County, Georgia's RFP for replacement of Cisco network switching and routing equipment with professional services (response due July 2, 2026).

The code shows little relevant recent activity for its nominal ISDN access device scope; the overwhelming volume of posted solicitations targets current-generation network infrastructure, switching, and routing systems. Buyers are primarily local and county government IT departments, school districts, and city information services divisions seeking authorized vendor relationships with Cisco, Palo Alto, HP, F5, Dell, Juniper, and Nutanix. Most opportunities are structured as competitive sealed bids or RFPs with response windows of two to four weeks, performance bonds and insurance requirements, and evaluation criteria emphasizing vendor authorization, experience with comparable enterprise or government deployments, and price. The code's nominal ISDN focus appears obsolete relative to what state and local procurement offices actually purchase under this number; code retag or platform correction may be warranted.
