VCL-MegaConnect 72 Ports T1
Digital Access Cross Connect Switch |
|
Product Overview
The 72 Port T1 DACS - VCL-MegaConnect is a T1 digital
cross connect switch which presents its user an easy to use platform to
cross connect up to T1 ports. The VCL-DACS, T1 Digital Cross Connect Switch
offers full cross connect functionality to cross connect between, and/or
aggregate DS-0s, "n"x64Kbps consecutive data channels and Fractional T1
channels to full T1 channels.
The Port T1 Digital Cross Connect Switch occupies only a
3U high rack-space and is a complete 19-inch stand-alone unit that provides
connectivity of up to T1 ports. The unit operates on a 48V DC input
power-supply. The system is supplied with a CLI text-based, easy-to-use
interface that offers the user complete control to prepare multiple
configuration maps (and store them as data files) and the ease of
downloading them from a PC. Dry contact relay alarms are also available at
rear of the system to connect the system to an external alarm. The 72 Port
T1 Digital Cross Connect Switch also has a TCP-IP Access feature which
allows the DACS to be connected on a TCP-IP network (10/100 base interface)
for remote access for configuration and monitoring.
Applications
- Providing fractional T1s to subscribers
- Data aggregation from fractional T1 channels
- Cellular extending fractional T1 ports from MTSO to cell-sites
- Cross connecting DS-0 time-slots between T1 ports.
