(e) RECEIVE PATH FILTER TIMINGS: Insertion time 13 +/–7msec; filter removal for SF tone shorter
than 175 +/–60msec is 180 +/–70msec; filter removal for SF tones longer than 175 +/–60msec is 50
+/–10msec.
(f) GUARD CIRCUIT TRANSITION TIMING: Enable time, 50+/–10msec; disable time, 225 +/–60msec.
(g) SF TONE DETECTION BANDWIDTH: Will detect within 2600 +/–15Hz; will not detect outside of
2600 +/–50Hz.

(k) HIGH LEVEL TONE TIMING: High level tone is transmitted for 400 +/–100msec following each busy
to idle transition.

tion.
