Abstract
A data modem aggregator system and a method of initializing a data modem is disclosed. In a particular embodiment, the data modem aggregator system includes a plurality of data ports configured to communicate data traffic. The data traffic is carried over dedicated data twisted pair lines. The data modem aggregator system further includes shared data processing resources to process the data traffic communicated over the plurality of data ports and a high-speed multiplexed output responsive to the plurality of data ports and the shared resources.In a particular embodiment, the method of initializing a data connection for a data modem includes detecting power-on of the data modem, handshaking from the data modem with a far end connection, negotiating a data rate with the far end connection, and communicating data between the data modem and the far end connection over a dedicated data twisted pair line. Each of the above steps in the initialization process is performed without receiving a dial tone and without dialing digits over a public switched telephone voice network.
