Technical Specifications: STM-1 (optical / electrical)
with upto 63 E1s with E3, DS3, 10/100BaseT Ethernet interfaces

Description

The VCL100MC-1 STM-1 (upto 63 E1) with E3, DS3, 10/100BaseT Ethernet interfaces is a compact, modular, and cost effective STM-1 SDH multiplexer equipment designed to manage bandwidth and provide E1 or fractional E1, voice and data access service over STM Networks. The STM-1 offers both electrical STM-1 (1+1) and optical STM-1 (1+1) interfaces. It is customized for the traffic demands, in the access network, typical of residential or business customers. The product supports end-to-end provisioning and management of services across all the 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.

VCL100MC-1 (upto 63 E1) with E3, DS3, 10/100BaseT Ethernet interfaces is a 3U height multi-card chassis system that provides flexibility to the customers in terms of expansion to support additional client interfaces by adding new modules in the field.

STM-1 VCL100MC-1 - upto 63 E1 / 84 T1 with E3, DS3, 8 port 10/100BaseT Ethernet interfaces

The system has two STM-1 optical / electrical interfaces in the aggregate side and allows for upto 3 tributary add-on cards. The following tributaries are available as add-on cards for the chasis:

  • E1
  • E3/DS3 tributaries (software configurable as E3 or DS3)
  • 10/100Base-T Ethernet (IEEE 802.3)
  • STM-1o
  • STM-1e/140Mbps tributary interfaces (software configurable).

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.

Additionally it provides a single 10/100Base-T Ethernet port, which can be mapped to one VC-12 bandwidth towards the aggregate side. This feature does not use any tributary slot and hence can supplement E1/DS1/E3/DS3 customers requiring a single Ethernet interface. This Ethernet interface on the base card is optional.
