E1 DXC
/ E1 DACS - Upto 80 x E1, 160Mbps
Digital Access Cross Connect Switch |
Overview:
The VCL-MX
Version 6 DXC - 80 x E1, 160Mbps Digital Access Cross Connect is a modular
switch which may be scaled from 8 E1 Ports to up to 80 E1 Ports. The VCL-MX Version 6, E1 DACS (E1 DXC) offers full cross-connect functionality
to cross-connect between 64Kbps time-slots (DS-0s), "n"x64Kbps consecutive
DS-0s and Fractional E1 channels to full E1 channels.
The VCL-MX
Version 6 DXC - 80 E1, 160Mbps 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 E1 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.
