Technical Specifications

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.

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.

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 chassis:

  • 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)

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.
