UNSPSC 43222822: Time division multiplexer TDM

A device that uses time-division multiplexing (TDM). This is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing. Optical technology and equipment which manages data frames in a series of time slots

UNSPSC 43222822 Time division multiplexer TDM (Commodity) covers specialized data and voice transmission equipment that consolidates multiple signals onto a single communication line, but the recent state and local opportunities posted under this code do not reflect actual TDM procurement. Wake County (North Carolina) solicited Cisco networking equipment for a single building site through an RFP due July 10, 2026, requiring authorized Cisco Channel Partner status and new equipment sourced directly from Cisco or its authorized partners; the Texas Department of Information Resources (DIR) issued a multiaward indefinite-quantity contract for cellular, wireless, pager, and satellite services plus related infrastructure for the Texas Agency Network (TEX-AN) with responses due July 23, 2026; and Sourcewell (on behalf of multiple Washington and other state jurisdictions) solicited law enforcement equipment through an RFP closed June 16, 2026. Of these three opportunities with clear technical scope, only the DIR solicitation involves multiplexing or signal consolidation (satellite and cellular infrastructure integration), while Wake County's procurement targets general network switching equipment and the Sourcewell solicitation spans law enforcement gear broadly. The remaining opportunities in the block—marketing consultant services for the North Florida Transportation Planning Organization, classroom technology services for Valencia College District, data abstraction and NLP software for Inland Empire Health Plan, and project management software for Jacksonville Transportation Authority—fall entirely outside telecommunications equipment and signal transmission. The code shows minimal genuine activity aligned with TDM scope; the single relevant opportunity (DIR's TEX-AN infrastructure contract) involves multiplexed voice and data services and equipment but is only one of seven postings.

Geographic activity centers on Texas (DIR's statewide procurement), North Carolina (Wake County), Florida (Valencia College and Jacksonville Transportation Authority), and Washington and subordinate jurisdictions (Sourcewell's regional cooperative). The DIR contract represents the most significant TDM-adjacent opportunity, calling for network buildout projects, equipment installation, and emerging technology deployment across Texas state agencies with pricing firm and fixed based on published commercial rates, a 2.00% administrative fee, and an initial four-year term with optional four-year renewal. Business development professionals should treat this code with caution; the preponderance of recent postings tagged to 43222822 are unrelated to multiplexing or time-division transmission equipment, suggesting either classification drift in the source system or misalignment between code taxonomy and actual procurement behavior at these issuers.
