Burglars realize most security systems sound inside the house and then the alarm is transferred to remote locations through the telephone lines. Most phone lines are typically exposed on the outside of the house in an easily accessible location where the phone line can be cut. If the telephone line is cut, the security alarm system cannot notify the central monitoring station of the break-in. If the phone line is run underground until it is inside the home (with the main telephone junction box inside the home), the thief cannot tamper with the telephone line until after he or she has broken in.
