Time-division multiplexing (TDM)

Time-division multiplexing (TDM) is a more traditional method of achieving PSTN connectivity through physical circuits over a single transmission. Signals are divided and assigned to fixed time slots, then regrouped into a complete signal upon their arrival.

How Bandwidth is Involved with TDM

As costs for maintaining TDM circuits increase, companies are actively migrating towards SIP for a more cost effective and scalable solution. Bandwidth provides quality-first SIP trunking services and SIP trunks so our customers can build their new telephony stack with confidence. Bandwidth owns and operates one of the nation’s largest and fastest growing All-IP Voice Networks.
