A method of transmitting signals between a source modem and a destination modem. The method includes transmitting the signals from the source modem, over a first switched network path, to a first interface, encapsulating the at least some of the signals received by the first interface into packets, transmitting the packets from the first interface over a packet-based network to a second interface, removing the encapsulation of the signals at the second interface; and transmitting the data signals from the second interface over a second switched network path to the destination modem.
