UNSPSC 43222803: Digital loop carrier DLCs

Digital loop carrier (DLC) is equipment that bundles a number of individual phone line signals into a single multiplexed digital signal for local traffic between a telephone company central office and a business complex or other outlying service area. Typically, up to 24 analog voice calls are combined into a single signal and transmitted over a single copper T-carrier system or E-carrier line, an optical fiber cable, or a wireless connection.

UNSPSC 43222803 Digital loop carrier DLCs is a Commodity code representing digital display hardware and installation services for transit and public-facing infrastructure. State and local governments are procuring under this code primarily full-color, high-visibility digital displays for transit buses, bus stop shelters, and transit centers—units that integrate with content management systems such as Message Point Media's MP.TV platform, support multiple operating systems (Android, Windows, Linux, macOS, ChromeOS), provide WiFi and 4G/FirstNet cellular connectivity, and include power management features such as solar integration, battery backup, and motion-sensor sleep modes. The work encompasses hardware procurement, on-site installation, warranty and repair policies, and knowledge transfer training. Issuing bodies include transit authorities and county governments. The Monterey-Salinas Transit District (MST) in California is a repeat buyer, soliciting three separate IFBs in October 2026 for displays across its bus fleet (83 buses), bus stop shelters without power infrastructure (50 locations), and transit centers and JAZZ shelters (39 total locations). Qualification thresholds are consistent across the transit authority's procurements: bidders must hold current California Contractor's Licenses, demonstrate three years of experience completing at least three similar projects, maintain a permanent business for a minimum five years, and provide financial statements and client references. Contracts exceeding $100,000 trigger five percent bid guarantees, 100 percent performance bonds, and 50–40 percent payment bonds depending on contract size; comprehensive insurance requirements include workers' compensation, commercial general liability, commercial automobile liability, and professional liability coverage ranging from $1 million to $2 million per occurrence.

Recent activity concentrates in California, where MST's three IFBs (IFB #27-01, #27-02, #27-03) are due November 4–5, 2026, with public bid openings on November 4, 2026, at 1:30 p.m. to 3:00 p.m. and anticipated contract awards December 14, 2026. Questions for MST's solicitations are due October 20, 2026. All three MST procurements are classified as Public Works subject to federal compliance obligations (Davis-Bacon Act, Buy America provisions where applicable) and California prevailing wage requirements under Labor Code Sections 1770–1780. Gwinnett County, Georgia issued RFP-2701KM for digital signage, scoreboards, video walls, LED displays, and related technologies with a proposal deadline of August 10, 2026; details on scope, specifications, and contract value are not available in the source. MST's repeat procurement activity across multiple display categories and locations within a single fiscal cycle signals sustained investment in transit digital infrastructure.
