The Enable PCM Upstream command is changed to AT+PIG=0.

In earlier firmware versions this command ( AT+PIG=1 ) enabled PCM upstream. This was changed to conform with the specification.

Command: +PIG=n PCM Upstream Enable
Values: n = 0 or 1
Default: 1

Description: Controls the use of PCM upstream during V.92 operation. PCM upstream allows faster upload speeds to a V.92 server.

+PIG=0 Enable PCM upstream

+PIG=1 Disable PCM upstream

+PIG=? Displays the allowed values

+PIG? Displays the currrent value


This command was changed in firmware version 1.28C or greater and can be downloaded from our Web site at:
