Adaptive Speed Leveling (ASL)
Courier V.32bis and V.32terbo modems detect improved line conditions and shift upward
again to the next higher speed. The modems at both ends of the connection adapt indepen-
dently, each detecting and adjusting to line conditions. ASL keeps the modems online,
always operating at the highest possible speed and con-stantly ensuring data integrity.
analog device B-channel
The I-modem distinguishes between an analog device B-channel and a data B-channel.
The analog device B-channel applies only to I-modems that have an analog device jack.
Any device you plug in to the analog device jack, like a telephone, fax machine, or
modem, needs a B-channel that supports circuit-switched voice (CSV).
analog signals
Continuous, varying waveforms, such as the voice tones carried over phone lines. Contrast
with digital signals
