Options latency

in /etc/modprobe.d/dahdi.conf write this command
options wctdm24xxp latency=4

what does it mean “latency”? For what using it? Please correctly and understandably write. Thanks for help

It refers to the buffering in milliseconds provided to account for disruptions on the PCI or PCI-E bus caused by other devices.

It adds latency to your transactions but it helps mitigate the presence of misbehaving devices, which is better than dropping calls.

it (latency)refers FXO and FXS ports?


It’s latency in transactions with the card.

ok i understood, thanks
