Tandem Network Transformation

Many communications service providers are constrained by legacy tandem or transit networks that are expensive to maintain, difficult to extend or past their lifecycles and posing risks. Ribbon's Tandem IP Network Transformation solution provides modern IP-based options, helping service providers offer efficient IP-based interconnects and exploit a flatter tandem/transit network architecture, which significantly reduces recurring power, HVAC, space and staffing costs.

As a leader in network transformation, Ribbon offers an extensive suite of tandem switching solutions based on powerful voice-over-IP platforms deployed globally in legacy TDM, hybrid TDM/IP, and IMS configurations. Ribbon’s tandem switching solutions provide seamless local and access trunk interoperability and eliminate interconnect barriers.
