Telecommuter system bandwidth requirements

A telecommuter system is commonly used in a Call Center for users working remotely. The PC and the telephone can transmit frames across the same telephone line (Road Warrior configuration), or on two lines (Telecommuter configuration). The bandwidth used by the PC for signaling is very low. However, it is difficult to express this value in bits per second due to the variability in how quickly the buttons are pressed and how many feature buttons are used during a call. Even with a 56K (V.90) modem, the upstream bandwidth is no greater than 33.6K and the downstream is anywhere from 28.8K to 53K. The speed of each connection is determined by the PSTN line conditions at the time the call is placed. Bandwidth required for signaling is almost negligible compared to the available bandwidth for voice.
