The DC1200 spans the gap between the synchronous interface of a bridge or router and the E1 leased line.

The DC1200 offers a V.35 interface and an E1 line interface with BNC or RJ45 connector options. Clocking modes are set by dip-switches which allow the unit to be set up for all applications.

The DC1200 can easily be rackmounted in either a 1U two unit rackmount kit, 1U quad box (4 x DC1200) or in a 6U eighteen unit rackmount kit.

Please Note: The DC1200 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 DC3200 (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.
