E1 DACS (DXC) 16 Ports Digital Access Cross Connect Switch - VCL-MegaConnect-Jr.

Description

Valiant offers its 16 port E1 Digital Access Cross Connect Switch (DACS / DXC) (and T1 DACS) for applications including access cross-connect, Hi-Z (high impedance) monitoring, automatic protection switching (1+1 APS). All models are available with TCP-IP remote access and monitoring facility.

The VCL-MegaConnect-Jr. 16 Port, E1 Digital Cross Connect Switch, is an E1 digital cross connect switch, which presents its user an easy to use, yet a sophisticated platform to cross connect up to 16 E1 ports. E1 Digital Cross Connect Switch offers full cross connect functionality to cross connect, and/or aggregate DS-0s, "n"x64Kbps consecutive data channels and fractional E1 channels to full E1 channels.

The 16 Port E1 Digital Cross Connect Switch occupies only a 2U high rack-space and is a complete 19-inch stand-alone unit that provides connectivity of up to 16 E1 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 16 Port E1 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.

The 16 Port E1 DACS - VCL-MegaConnect Jr can also be ordered for special non- intrusive (Hi-Z) monitoring applications in which (pre-assigned monitoring ports) E1 ports can be connected to monitoring/billing equipment for live traffic monitoring (non-intrusive monitoring).
