Network Service to Customer Equipment Conversion

DC1000 used to provision an X.21 service via an E1 2Mbps G.703 leased line

E1 2Mbps leased line services typically offer a BNC or RJ45 physical presentation to the customer whereas the customer generally has an X.21 WAN serial interface on his router.

Whilst interface modules may well be available to connect the router directly to the G703 BNC/RJ45, generally they're much more expensive than an interface converter, and more complex to install and maintain.

The customer wants the cheapest service with the least hassle, and so the best solution is for the service provider to provide the required router interface as part of his service. The service provider also gets the advantage of having a differentiated service which will make it more difficult for the customer to change service providers in the future.

Metrodata developed the DC product range for exactly this application, with an emphasis on achieving the highest possible MTBF (mean time between failure) for these products.

By integrating these interface converters into their product offering, service providers can offer their customers the exact service they want, so that these customers can standardise on their chosen X.21 or V.35 router interface card in the knowledge that this can be used everywhere in your network, reducing inventory as well as support and maintenance costs.
