STM-4 (upto 252 E1)
Technical Specifications
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.
