The second type of 10-digit emergency number are those used so that
PSAPs can receive emergency calls from other PSAPs, including
out-of-state PSAPs; and so that Central Station alarm companies can
deliver their emergency alarm activation notifications to the correct
Connecticut PSAP; and finally to provide a default route for telephone
companies - both wireless and wireline - to be able to deliver a 9-1-1
call to a PSAP when they cannot get their customer's 9-1-1 calls into
our network core for delivery.

Please remember: You should always call 9-1-1 during an emergency, but
as a backup you should also designate an emergency contact in your
phone and have your local Police Department or Troop telephone number
programmed into your phone.
