Monitoring of Card Outputs
4.2510 Input cards, track and hold cards, and most output driver cards have monitoring
jacks intended for use with a standard test set with a monitor input (100 ohms
for DS1 and EIA RS-422, 130 ohms for CC, 120 ohms for E1; 20 dB standard
level). The signals available are:
