    Abstract: A fast startup procedure for a modem system utilizes known characteristics of a previously established communication channel to reduce the initialization period associated with subsequent connections over the same channel. In response to the establishment of a call, the modem devices determine whether the fast connect protocol is supported. If so, then the called modem transmits a modified answer tone to the calling modem. The calling modem analyzes the signal received in response to the modified answer tone to determine whether characteristics of the current channel are similar to stored characteristics associated with a previous connection over the same channel. If a channel “match” is found, then the modem devices carry out a fast initialization routine that eliminates, abbreviates, or modifies a number of procedures or protocols that are carried out in conventional modem startup processes.

    Abstract: A modem system having two modem devices digitally connected to a digital telephone network includes an inband control signal channel. The inband control signal channel is formed by using the most significant bit position of every sixth transmitted codeword for the transmission of control data. The control signal includes a predetermined header section that is monitored by the receiving modem to maintain frame synchronization and to correct for digital frame slippage. The control signal also includes a number of control data packets that contain information related to the initiation of control procedures such as rate renegotiations and retraining requests. The disclosed inband transmission techniques may additionally (or alternatively) be utilized to define a secondary data channel.

    Abstract: An apparatus and method for configuring a gateway device for a modem over packet network session is disclosed. For example, a system may include a first gateway device coupled to a first client device and a second gateway device coupled to a second client device, where the first gateway device is coupled to the second gateway device over a packet network. The trans-compression types and capabilities of the first and second gateway devices are determined and used to generate a set of negotiation parameters. The first gateway device then negotiates with the first client device using the negotiation parameters to select a first compression algorithm. A second compression algorithm selected between the second gateway device and the second client devices is also determined by the first gateway device. Then, the trans-compression mode of operation of the first gateway device is configured based on the trans-compression types and capabilities of the first and second gateway devices and the selected first and second compression algorithms. The second gateway device may be similarly configured.
