T-1
T-1s are the backbone of digital service today. A T-1 is a standards-based transmission format. It processes voice or data digital signals over telephone facilities. Many businesses may use a T-1 to connect their PBX system to the public switched network to bridging, or routing between LAN networks, or as transmission devices between microwave stations. T-1s are popular for several reasons. One being that a T-1's circuit size. It can make 24 communication channels on one circuit. A second reason being that smaller trunk groups can be configured on a single T-1. Basic T-1 technology is converting analog waves to digital and back to analog. A voice that is being spoken creates an analog sound wave and the telephone creates an electrical representation of the analog waves. When the pitch or frequency would change, the electrical current would change accordingly. A conversion or coding is necessary to convert the analog sound waves to digital. In order to convert analog waves to digital, samples are extracted from the analog waves. The samples of analog waves are taken about 8,000 times every second, which is coded into a 8-bit word (also known as a byte). This procedure is executed by pulse code modulator (
