Description

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 timeslot) 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 fromMTSOto 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.

Highlights
