Communication on hold
First Claim
1. A method for use by a first modem while in a communication with a second modem via a communication network, said method comprising the steps of:
- receiving a call waiting tone by said first modem from said communication network;
receiving a first single tone from said second modem as a result of an interruption in said communication caused by said call waiting tone;
transmitting, during said step of receiving said first single tone, a second single tone followed by a hold notification bit pattern to said second modem in response to said interruption;
receiving a hold refusal bit pattern from said second modem in response to said hold notification bit pattern; and
sending a disconnect bit pattern to said second modem in response to said hold refusal bit pattern.

Abstract
A communication session is established between an APCM modem and a DPCM modem. The central office interrupts the communication session by transmitting a call-waiting alert signal to the APCM modem. In response to the alert signal, the APCM modem transmits a caller ID data request to the central office. The APCM modem further transmits an on hold notification to the DPCM modem to prevent the DPCM modem from terminating the communication session as a result of the interruption by the alert signal and/or receipt of the caller ID data by the APCM modem. The DPCM modem is placed on hold while the APCM modem answers the call waiting. Subsequently, the APCM modem initiates a quick connect procedure to re-establish the communication session with the DPCM modem.

11. A first modem in a communication with a second modem via a communication network, said first modem comprising:
-
a receiver capable of receiving a call waiting tone from said communication network, and further capable of receiving a first single tone from said second modem as a result of an interruption in said communication caused by said call waiting tone; and
a transmitter capable of transmitting, during said step of receiving said first single tone, a second single tone followed by a hold notification bit pattern in response to said interruption;
wherein said receiver receives a hold refusal bit pattern from said second modem in response to said hold notification bit pattern, and said transmitter sends a disconnect bit pattern to said second modem in response to said hold refusal bit pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
