Introduction STM-1/4 SDH Multiplexer:

The VCL100 STM-1/4 is a modular, and cost effective STM-1/4 SDH multiplexer equipment designed to manage bandwidth and voice & data access services over STM networks. The products are designed to support end-to-end provisioning and management of services across all segments of the optical network. It combines innovative optical networking software with the intelligence of SONET/SDH to deliver a flexible, cost-effective network solution.

The VCL100 STM-1/4 provides flexibility to the customers in terms of expansion to support additional client interfaces by adding new modules in the field. It is also a scalable system that enables the customer to start with an STM-1 network and upgrade to STM-4 as the traffic demand increases.

The distinguishing features of VCL100 STM-1/4 over competing products are its unprecedented port density, scalability, redundancy and upgrade-ability with its software intelligence. The VCL100 STM-1/4 family of products can be managed through an integrated NMS that manages all STM equipment, providing customers with end-to-end provisioning from a single platform for multiple service types – from E1s, E3s, STM-1, STM-4, and 10/100Mbps Ethernet services.

The STM-1 / STM-4 can be managed through an integrated NMS that manages all the equipment, providing customers with end-to-end provisioning from a single platform for multiple service types - from E1/DS1s, E3/DS3s, E4/STM-1e, STM-1o and 10/100Mbps Ethernet services.
