ABSTRACT:
Modem start-up delay reduced by measuring condition of communications line upon connection termination. Variation between termination and start-up line conditions determines if cold or warm start is required. Warm-start may use original condition descriptors. Condition represented by ambient noise, echo or spectral response of channel.
