Fractional E1 (Nx64kbps) G.703/G.704 to V.35 Converter

Router Applications

• V.35 router to E1 2Mbps G.703 leased line conversion
• Connecting pairs of V.35 routers over an E1 2Mbps G.703 leased line
• E1 G.704 router to Nx64kbps V.35 leased line conversion
• Connecting pairs of E1 G.704 routers over a Nx64kbps V.35 leased line

PBX Applications

• PBX PRI to V.35 2Mbps leased line conversion
• Connecting pairs of PBXs over a 2Mbps V.35 leased line

Satellite Applications

• Connecting E1 G.703 routers to V.35 satellite modems

This application shows a DC3200 connecting a V.35 router card to an 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. both ends unframed or both ends framed). If the leased line is framed then the equipment at both ends of the leased line must also be framed.

This application shows a DC3200 connecting an E1 G.704 router card to a V.35 Nx64kbps leased line, such as a BT Kilostream-N service. Care must be taken to ensure that the remote equipment is configured in a compatible manner (i.e. either V.35 or E1 G.704 framed). This application requires a V.35 DCE to V.35 DCE crossover cable. Please note that this application will NOT work where E1 timeslot integrity is required (e.g. when using channelised E1 cards in the routers).

This application shows a pair of DC3200 units connecting a pair of E1 G.704 routers via an V.35 Nx64kbps leased line, such as a BT Kilostream-N service. Care must be taken to ensure that the remote equipment is configured in a compatible manner (i.e. either V.35 or E1 G.704 framed). This application requires the use of V.35 DCE to V.35 DCE crossover cables. Please note that this application will NOT work where E1 timeslot integrity is required (e.g. when using channelised E1 cards in the routers).

This applications show a DC3200 being used to connect a PBX PRI port to a 2.048Mbps V.35 leased line, for when either an existing X.21 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. Please note that this application will NOT work over an Nx64kbps service, e.g. a BT Kilostream-N.

This applications shows how a pair of PBX systems can be connected together via a 2.048Mbps leased line using a pair of DC3200 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. Please note that this application will NOT work over an Nx64kbps service, e.g. a BT Kilostream-N.

This application shows a DC3200 connecting an E1 G.703 router card to a V.35 satellite modem. The DC3200 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 DC3200 or router. This application requires a V.35 DCE to V.35 DCE crossover cable. Please note that this application will NOT work where E1 timeslot integrity is required (e.g. when using channelised E1 cards in the routers, or when using a PBX).

Product variants with 12V to 24V DC operation are also available on request.
