VCL-MX Version 6 DXC - 80 T1, 120Mbps
Digital Access Cross Connect Switch

Product Overview

AceCom offers VCL-MX Version 6 DXC – 80 T1, 120Mbps Digital Access Cross Connect is a modular switch which may be scaled from 8 T1 Ports to up to 80 T1 Ports. The VCL-MX Version 6, T1 DACS (T1 DXC) offers full cross-connect functionality to cross-connect between 64Kbps time-slots  (DS-0s), "n"x64Kbps consecutive DS-0s and Fractional T1 channels to full T1 channels.

VCL-MX Version 6 DXC - 80 T1, 160Mbps DACS - Data Sheet (PDF)

The VCL-MX Version 6 DXC – 80 T1, 120Mbps Digital Access Cross Connect Switch, occupies 6U high (264 mm) rack-space and is a complete 19-inch standalone unit that provides a 64Kbps time-slot (DS-0) cross-connect fabric for up to 80 T1 ports. This product offers 1+1 -48V DC Power Supply Redundancy, 1+1 Control Card and Processor Redundancy, 1+1 Cross-Connect (TSI) Redundancy, 1+1 Timing (Synchronization Clock Circuitry) Redundancy. This DXC offers “user selectable” clock / timing synchronization priority. The Dual Power Inputs allow the equipment to be powered from two separate power sources. AC input external adapter is an optional for AC mains operation.
