VCL-MegaConnect 72 Port E1
Digital Access Cross Connect Switch (DACS)

Product Overview

VCL-MegaConnect - 72 Port E1 DACS

Orion Telecom Networks Inc. offers the VCL-MegaConnect - 72 Port E1 DACS is an E1 digital cross-connect switch which presents its user an easy to use platform to cross-connect at the 64Kbps (DS-0) time-slot , level between the 72 E1 ports.

The VCL-MegaConnect - 72 Port E1 DACS offers full cross-connect functionality to cross-connect between DS-0s, "n"x64Kbps consecutive DS-0s and Fractional E1 channels to full E1 channels.

The VCL-MegaConnect - 72 Port E1 DACS occupies only a 3U high rack-space and is a complete 19-inch stand-alone unit that may be used to cross-connect between the 72 E1 ports. The unit offers 1+1 -48V DC power supply redundancy.

The system supports a CLI text-based, menu as well as an easy-to-use Graphical User interface (GUI) that offers the user complete control to prepare multiple configuration maps (and store / save them as data files) for the ease of downloading them from a PC. Dry contact relay alarm is also available at rear of the system to connect the system to an external alarm / audio buzzer.

The VCL-MegaConnect - 72 Port E1 DACS also has a TCP/IP Access port which allows the DACS to be connected on a TCP/IP network (10/100BaseT ethernet) for remote access for configuration and monitoring. The system also supports SNMP V2 monitoring / trap capability.

Applications

  • Providing fractional E1s
  • Data aggregation from fractional E1 channels
  • Cellular extending fractional E1 ports from MTSO to cell-sites
  • Cross connecting DS-0 time-slots between E1 ports.
