DC3200 connecting a V.35 router to an unframed or framed E1 G.703/G.704 leased line

dc3200-router-v35-e1g704-cloud.png

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.

V.35 routers connected together via an unframed or framed E1 G.703 leased line using DC3200 units

dc3200-router-v35-e1g704-cloud-v35-router.png

This application shows a pair of DC3200 units connecting a pair of V.35 routers via 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.

DC3200 connecting an E1 G.704 router to a V.35 Nx64kbps leased line

dc3200-router-e1g704-v35-cloud.png

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).

E1 routers connected together over an V.35 Nx64kbps leased line using DC3200 units

dc3200-router-e1g704-cloud-v35--e1g704-router.png

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).

DC3200 connecting a PBX to a 2.048Mbps V.35 leased line

dc3200-pbx-e1g704-v35-cloud.png

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.

PBXs connected together via a 2.048Mbps V.35 leased line using DC3200 units

dc3200-pbx-e1g704-cloud-v35--e1g704-pbx.png

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.

Connecting E1 routers to V.35 satellite modems

dc3200-router-e1g704-v35-satmodem.png

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).

The DC3200 offers conversion between a V.35 serial interface and an E1 line interface with BNC or RJ45 connector options. The DC3200 supports both unframed and framed (or fractional) operation.

Fractional operation allows a number of 64kbps timeslots to be active, up to a maximum of 31 timeslots for a single E1 line. If timeslot 16 is bypassed, then a maximum of 30 timeslots (channels) can be accommodated.

The DC3200 has a simple multi-function status LED and BIT switch configuration with comprehensive configuration and diagnostic information on the unit base label making the DC3200 a truly plug and play device.

The DC3200 range can easily be rack mounted in either a 1U two unit rack mount kit, a 6U eighteen unit rack mount kit or also available in quad box option (4 x DC3200 units).
