The DC1000 provides a new level of price/ performance for connecting bridges and routers to unstructured E1 G.703 2Mbps leased lines.
A G.703 interface is required to connect a LAN bridge or router to a 2Mbps leased line. The DC1000 spans the gap between the synchronous interface of a bridge or router and the E1 leased line.

Rear: DC1000 - E1 G.703 to X.21 Converter
The DC1000 offers an X.21 interface and an E1 line interface with BNC or RJ45 connector options.
Clocking modes are set by bit-switches which allow the unit to be set up for all applications.
The DC1000 can easily be rackmounted in either a 1U two unit rackmount kit, 1U quad (4 x DC1000's) box or in a 6U eighteen unit rackmount kit.
Please Note:
The DC1000 unit is for an unframed (clear) 2mbps E1 G.703 circuit.If you have a framed (fractional) E1 G.704 circuit i.e. n x 64kbps, or require framing, a DC3000 (unmanaged) or FM4000 (managed) is required. Many BT services provide a framed or fractional E1 link, please double check with your provider if you are using a BT service with this product.
