Abstract:
1. A method of bridging a call in a network using Integrated Services Digital Network (ISDN) User Part (ISUP) traffic messages, comprising the steps of: requesting a setup of a first call to a first destination point from a switching center using an Initial Address Message (IAM) including a first Circuit Identification Code (CIC) representing a first end of a loop-around facility associated with a first port of said switching center; directing said first call to said first destination point from said first end; upon said first destination point answering said first call, receiving a first call establishment message associated with said call including an Address Complete Message (ACM) and an Answer Message (ANM); requesting a set-up of a second call to a second destination point from said switching center using an Initial Address Message (IAM) including a second Circuit Identification Code (CIC) representing a second end of said loop-around facility associated a second port of a switching center; said second CIC correlating with a circuit associated with said first CIC; directing said second call to said second destination point from said second end; upon said second destination point answering said second call, receiving a second call establishment message associated with said second call including an Address Complete Message (ACM); and bridging said destination points using said loop around transport facility utilizing a switching fabric inherent to said switching center.
