Primary and Secondary Phone Numbers

When the T3SU 300 dials out to send a trap, it first dials the

PRIMARY PHONE NUMBER. If the call is unsuccessful, it tries the

SECONDARY PHONE NUMBER. Attempts between the two numbers continue until a call is established and the trap is reported (or until each number’s maximum for redial attempts is reached).
