Abstract

Embodiments of the present disclosure relate to a communication system for managing leased line networks. The system comprises of a router to route data from one network to another network, and a V.35 modem configured to receive the data from the router and transmit the data to a predefined destination using internet protocol (IP) network. The interface which connects the router with the V.35 modem is a V.35 interface. The IP network requires an ethernet interface to receive the data and to transmit the data to a destined location. The V.35 modem designed converts the V.35 interface to an ethernet interface, but since the ethernet interface is expensive, the V.35 modem converts the ethernet interface to an ADSL interface for establishing ADSL connection towards the IP network. The system further comprising an interface to 3G/LTE/Wifi which is used as a redundant path in the event of failure of ADSL interface.

Dependent claims

A modem for managing a leased line network comprising:

a physical interface block 401 to receive data using an interface and to generate predetermined data signals for the received data, wherein the received data is from one of a router 102 and an IP network 203;
an ethernet processor block 403 to receive the predetermined data signals to generate ethernet packets;
Asymmetric digital subscriber line (ADSL) processor block 404 to receive the ethernet packets to generate ADSL data, said ADSL processor block establishes communication between the modem and the internet protocol (IP) network;
interface block (405, 406) connected to the ADSL processor block 404 to perform at least one of transmitting the ADSL data onto the IP network 203 or receiving data from IP network 203;
and
Universal Serial Bus (USB) interface wireless block 407 connected to the ethernet processor block 403 to provide wireless communication between the modem 201 and the IP network 203 during a failure of the interface block (405, 406);
wherein the ADSL data is at least one of decrypted signals if transmitted to an IP network 203 and encrypted signals if transmitted to a router 102.
