|   PRODUCTS   |

Description

The VCL100CPE Service Access Node is an ultra-compact and cost-effective customer premises bandwidth provisioning equipment designed to meet low or medium capacity bandwidth service demands.

This unique product is part of a family of STM-1 Multi-Service Provisioning and Access Nodes from Comarra. As with all products in Comarra family, the Service Access node also supports end-to-end provisioning and management of voice and data services across all the segments of the optical network - from the customer premises to the core. It combines innovative optical networking software with the intelligence of SDH to deliver a flexible solution to today's service providers.

The VCL100CPE can be configured as a Terminal Multiplexer (TMUX) or an Add-Drop Multiplexer (ADM), with E1, E3, DS3 or 10/100 Ethernet Interface service interfaces and trunk interfaces at STM-1 rate. The product has a built in non-blocking cross-connect at VC-3 and VC-12 granularity for efficient traffic grooming. In view of the growing demand for packet services, VCL100CPE provides an Ethernet tributary interface to carry inter-office traffic from corporate LANs, campus networks or from ISPs.
