Patent ID: 7634070

Claim:
A method of reducing time for use by a first modem to connect to a second modem via a communication channel, said first modem being in communication with a handset, said method comprising: receiving a first digital impairment learning sequence from said second modem over said communication channel; determining first one or more digital impairment attributes of said communication channel based on analyzing said first digital impairment learning sequence; interrupting said communication channel; terminating said interrupting; receiving a signal point sequence from said second modem; determining second one or more digital impairment attributes of said communication channel based on analyzing said signal point sequence; initializing said first modem with said one or more parameters to reconnect to said second modem if said first one or more digital impairment attributes are similar to corresponding said second one or more digital impairment attributes; wherein said first modem comprises, an off-hook detector capable of detecting said handset going off-hook, while said first modem is in communication with said second modem, and further being capable of generating an attention signal in response thereto; and a transmitter capable of transmitting a hold request to said second modem in response to said attention signal; wherein said handset is placed off-hook by a user for dialing an outgoing call, and wherein said communication between said modems over said communication channel ceases for a period of time after transmitting said hold request, and wherein said first modem keeps an upper layer protocol alive during said period of time.
