Abstract
A system and method for allowing multiple digital subscriber line modems to access a telephone line. The embodiments employ additional signaling protocols to enable equipped modems to distinguish between initiating and responding signals from initiating customer premise modems and telephone company central office devices. The additional signaling can take many forms that can be detected and used to distinguished signals. Preferably, the signal is a stealth signal as to not interfere with existing communication devices. A variety of application and embodiments are disclosed to enable a solution allowing multiple modems to access a telephone line.
