STS-1 SONET Multiplexer

HiGain The HiGain HXU-359 STS-1 multiplexer is a cost-effective SONET access platform that enables direct insertion of DS1s or E1s onto any SONET network via an economical STS-1 interface. This environmentally hardened unit enables installation in a co-location cage or remote cabinet. The HXU-359 condenses SONET technology into the highest service density multiplexer that minimizes space, power and heat dissipation requirements. The HXU-359 offers a mixed T1/E1 service of up to 28 DS1s or 21 E1s or any valid combination onto a single high-speed STS-1 network interface. This software-enabled feature eliminates unecessary upgrades, equipment changes and configuration. The HXU-359 can greatly reduce capital costs by eliminating the need for demultiplexing and cross connects. Flexible time slot assignment and VT mapping capabilities enables direct insertion of DS1s directly into any group/slot of the STS-1 payload envelope.
