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 is a Commodity code that does not align with the recent state and local opportunities posted under it. The opportunities actually solicited—Cisco Catalyst 9500 network switches, Apple branded products and services, cellular and wireless infrastructure, and law enforcement equipment—fall outside the narrow scope of time division multiplexing hardware. This code shows little relevant recent activity; the mismatch between the nominal commodity definition and the work actually being bought suggests misclassification in the posting systems rather than active procurement under the intended scope.

State and local issuing bodies posting under this code include county sheriffs offices (Chatham County, Georgia), state IT procurement offices (Texas Department of Information Resources), county IT departments (Wake County, North Carolina), and cooperative purchasing consortia (Sourcewell). The recent opportunities span Georgia, Texas, North Carolina, and a multistate cooperative framework. Representative solicitations include Chatham County Sheriff's Office ITB 26-0114-6 for two Cisco Catalyst 9500 network switches and related OEM hardware, licenses, and support, with bids due October 20, 2026; Wake County's ITB 26074 for Cisco networking equipment at the Sommerset 2 site, bids due July 10, 2026; and Sourcewell RFP 061626 for law enforcement equipment on behalf of participating entities across multiple states, proposals due June 16, 2026. None of these solicitations address time division multiplexing as a discrete product line.
