VCL-MegaConnect Jr.
16 Port E1/T1 Mixed Configuration DACS and
Interface Converter
| VCL-MegaConnect
Jr., 16 Port E1/T1 mixed configuration DACS and interface
converter shall allow the user to cross connect between E1 and
T1 interfaces at DS-0 (64 Kbps |

|
time-slot) level and use it for interface, frame and line-code
conversion between 8 E1 interfaces and 8 T1 interfaces. |

The VCL-MegaConnect Jr., 16 Port E1/T1
mixed configuration DACS and interface converter occupies only a 2U high
rack-space and is a complete 19-inch stand-alone unit that provides
connectivity of up to 16 E1/T1 Ports. The unit operates on a - 48V DC
input power-supply (AC input adapter is optional).
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 VCL-MegaConnect Jr., 16 Port E1/T1 mixed
configuration DACS and interface converter 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
- ISP providing fractional E1/T1s to subscribers
- Data aggregating fractional E1/T1 data circuits
- Cellular extending fractional E1/T1 Ports from MTSO
to cell-sites
- DS-0 (64 Kbps) time-slot cross connect between E1
and T1 Ports.
- Interface conversion (only interface, frame and
line-code conversion) between E1 and T1 Ports
