Trunk design optimization for public switched telephone network

A computer readable medium storing a computer program that identifies misrouted traffic in a telecommunications network for use in optimizing design of the network, the telecommunications network comprising at least a first switch and a second switch directly connected by a trunk, the computer program comprising:

• a first determining code segment that determines whether traffic from the first switch to the second switch passed through a third switch during a select time period;
• a second determining code segment that determines whether the direct trunk experienced overflow during the select time period;
• and
• a designating code segment that, when traffic from the first switch to the second switch is determined to have passed through the third switch during the select time period, and when the direct trunk is determined not to have experienced overflow during the select time period, designates traffic that passed through the third switch as misrouted traffic.

A computer readable medium storing a computer program that identifies misrouted traffic through a community of interest in a telecommunications network for use in optimizing design of the telecommunications network, the community of interest comprising a first end office connected via a direct trunk to a second end office, and a tandem switch connected to the first end office and the second end office, the computer program comprising:

• a first receiving code segment that receives empirical call data from the telecommunications network;
• a second receiving code segment that receives empirical trunk capacity utilization data from at least one of the first end office and the second end office;
• a first determining code segment that determines that traffic passes through the tandem switch based on the empirical call data;
• a second determining code segment that determines that the direct trunk experiences an overflow condition based on the empirical trunk capacity utilization data;
• a synchronization code segment that determines whether the traffic passed through the tandem switch during a time period when the direct trunk experienced the overflow condition;
• and
• an identifying code segment that identifies the traffic that passed through the tandem switch as misrouted traffic when the synchronization code segment determines that the traffic did not pass through the tandem switch during the time period when the direct trunk experienced the overflow condition.
