DC1200: Unframed E1 to V.35 Converter

DC1200 connecting a V.35 router to an unframed E1 G.703 leased line

This application shows a DC1200 connecting a V.35 router card to an unframed E1 G.703 2.048Mbps leased line, such as a BT Megastream-2 service. V.35 serial ports are often the most cost effective WAN port available on routers. Most Telecom carriers provision E1 2.048Mbps services with G.703 connectivity. Care must be taken to ensure that the remote equipment is configured in a compatible manner (i.e. V.35 or unframed E1 G.703).

V.35 routers connected together via an unframed E1 G.703 leased line using DC1200 units

This application shows a pair of DC1200 units connecting a pair of V.35 routers via an unframed E1 G.703 2.048Mbps leased line, such as BT's Megastream-2 service. V.35 serial ports are often the most cost effective WAN port available on routers. Most Telecom carriers provision E1 2.048Mbps services with G.703 connectivity. Care must be taken to ensure that the remote equipment is configured in a compatible manner (i.e. unframed).

DC1200 connecting an E1 G.703 router to a V.35 2.048Mbps leased line

This application shows a DC1200 connecting an E1 G.703 router card to a V.35 2.048Mbps leased line, such as a BT Megastream-2 service. Care must be taken to ensure that the remote equipment is configured in a compatible manner (i.e. either V.35 or unframed E1 G.703). This application requires a V.35 DCE to V.35 DCE crossover cable.

E1 routers connected together over an V.35 2.048Mbps leased line using DC1200 units

This application shows a pair of DC1200 units connecting a pair of E1 G.703 routers via a V.35 2.048Mbps leased line, such as BT's Megastream-2 service. This application requires the use of V.35 DCE to V.35 DCE crossover cables.

DC1200 connecting a PBX to a 2.048Mbps V.35 leased line

This applications show a DC1200 being used to connect a PBX PRI port to a 2.048Mbps V.35 leased line, for when either an existing V.35 leased line is available for re-use or alternatively when V.35 connectivity has been provided rather than G.703 (e.g. for economic reasons). This application requires a V.35 DCE to V.35 DCE crossover cable.

PBXs connected together via a 2.048Mbps V.35 leased line using DC1200 units

This applications shows how a pair of PBX systems can be connected together via a 2.048Mbps leased line using a pair of DC1200 units. This would occur either when an existing V.35 leased line is available for re-use, or alternatively when V.35 connectivity has been provided rather than G.703 (e.g. for economic reasons). This application requires the use of V.35 DCE to V.35 DCE crossover cables.

Connecting E1 routers to V.35 satellite modems

This application shows a DC1200 connecting an E1 G.703 router card to a V.35 satellite modem. The DC1200 supports a number of different clocking modes, and so it is possible to source the clocking for this network from the satellite modems, from one of the terrestrial circuits or from a DC1200 or router. This application requires a satellite link operating at 2.048Mbps and a V.35 DCE to V.35 DCE crossover cable.

The DC1200 offers conversion between a V.35 serial interface and an E1 line interface with BNC or RJ45 connector options.

The DC1200 has a simple multi-function status LED and BIT switch configuration with comprehensive configuration and diagnostic information on the unit base label making the DC1200 a truly plug and play device.

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

The DC1200 is also available in a card based format for use with the 4U 12-slot MetroRack managed chassis.

Please Note:

The DC1200 unit is for an unframed (clear channel) 2Mbps E1 G.703 circuit. If you have a framed (fractional) E1 G.704 circuit, i.e. Nx64kbps, or require framing, a DC3200 (unmanaged) or FM4000 (managed) is required. Many carrier services provide a framed or fractional E1 link, please double check with your provider to ensure that you are using a clear channel 2Mbps E1 G.703 leased line service with this product.
