TELEBYTE MODEL 457 WIRE LINE SIMULATOR
The Telebyte Model 457 Wire Line Simulator is a compact laboratory or field instrument. It precisely simulates the frequency response and propagation delay of a single, 26 AWG (0.4mm), telephone pair from DC up to 1.5 MHz. This product is intended for developing and testing higher speed local loop transmission products for ADSL, HDSL, T1 and E1 applications. The unit contains internal sections representing 500 ft, 1,000 ft, 2,000 ft, 4,000 ft. and two- (2) 8,000 ft, of cable. These sections can be connected in series by operating six (6) independent push button switches, or by using either the RS232 or IEEE 488.1,488.2 interfaces which allow the user to obtain any length of cable from 0 to 23,500 ft in 500-foot increments.
