Abstract
A modem dynamically selects the type of error-control negotiation sequence as a function of a negotiated parameter of the physical layer. In one embodiment of the invention, a modem selects between error-control negotiation sequences as a function of the type of modulation negotiated in the physical layer. In particular, the modem has at least two type of error-control negotiation sequences to select from: 'LAPM or Disconnect,' and 'LAPM, MNP or Buffer.' When the modem negotiates a V.32 or higher modulation, the modem uses the 'LAPM or Disconnect' error control negotiation sequence. However, when the modem negotiates a V.22 bis or lower modulation, the modem uses the 'LAPM, MNP or Buffer' error control sequence.
