Product Overview

Orion Telecom Networks Inc. offers VCL-MX Version 6 - E1 Multiplexer may be used for inter-connecting legacy networks, provisioning and managing bandwidth on a E1 channelized level as well as 64Kbps, DS-0 time-slot level and as a digital-access cross-connect equipment. Due to the changing traffic patterns, there is a need to support multiple services from the same equipment like integrated data transport, better network management etc. This necessitated evolution to next generation E1 Multiplexer. Redundant power supply options make it an ideal solution for network service providers seeking to integrate and provide legacy and the next generation services from a single platform.

Next generation E1 Multiplexer has emerged as one of the most economical and technologically viable solutions for transmitting both over carrier networks. This technology offers savings on investments/ power and space to service providers.

Orion Telecom provides efficient solutions in this field using the E1 Multiplexer series products. E1 Multiplexer provides a full range of solutions in this evolving field of next generation telecom solutions. E1 Multiplexer family provides the unique advantage of carrying both data and voice over PDH. In addition to being affordable, these products have built-in modularity, which allow easy upgradeability. This upgradeability feature allows the customer to evolve in a “build-as-you-grow” concept. Along with the Orion Telecom as Network Management solution the E1 Multiplexer family provides the following features:

Easy network manageability
Lower cost per line
Easy upgradeability
Carrying both data and voice over PDH
Easy integration to SDH network
Higher reliability.
