Description This command configures a voice channel for idle or seized fault signaling.
On the 6-port E&M Adapter card, this command is valid only if signaling-mode is configured
for E&M signaling. The 6-port E&M Adapter card also supports configuration of the idle and
seized codes.
Configuration of the idle and seized codes is not supported on the FXO and FXS channels
on the 8-port Voice & Teleprotection card, or on the 8-port FXO Adapter card or 6-port FXS
Adapter card. The code transmitted depends on signaling type and companding law as
shown in Table 30.
