80 Ports E1 DXC / DACS
Digital Access Cross Connect Switch

Description

Up to 80 Port E1 DACS / E1 DXC - Digital Cross Connect Switch, is a E1 (and T1) digital cross-connect switch platform offers full cross-connect functionality to cross-connect between DS-0s, "n"x64Kbps consecutive DS-0s and Fractional E1 channels to full E1 channels. The 80 Porst DACS / DXC presents its user an easy to use, yet a sophisticated platform to cross-connect up to 80, E1 ports.

Up to 80 E1 Digital Cross Connect Switch, occupies only a 3U high (132mm) rack-space and is a complete 19-inch standalone unit that provides connectivity for up to 80 E1 (or T1) ports. The unit operates on a 1+1, redundant -48V DC input power-supply (AC input adapter is optional for AC mains operation).

The system supports a CLI text-based, menu as well as an easy-to-use Graphical User interface (GUI) that offers the user complete control to prepare multiple configuration maps (and store / save them as data files) for the ease of downloading them from a PC. Dry contact relay alarm is also available at rear of the system to connect the system to an external alarm / audio buzzer.
