Sorry it looks like I figured out what is the reason.

/etc/config/network

   option keepalive 10

/lib/netifd/proto/ppp.sh

        local interval="${keepalive##*[, ]}"
        [ "$interval" != "$keepalive" ] || interval=5
...
     ${keepalive:+lcp-echo-interval $interval lcp-echo-failure ${keepalive%%[, ]*}}

keepalive is necessary to specify a comma-separated values​​, or the interval is set to 5:

syntax: option keealive '<failure> [, interval]'
