14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
Jitter tolerance is a measure of the amount of jitter (amplitude for a given frequency) that can be applied to the
input ports of the E1 LIU and still maintain signal integrity. The two pieces of equipment most commonly used
in the EXAR laboratory are the W&G ANT-20 and the OMNI BER from Agilent. The network analyzer runs a
sweep of frequencies ranging from 10Hz to 100kHz. Each frequency step (component) becomes a data point
at which the amplitude (UI, Unit Interval) is increased until bit errors are detected within the bit error tolerance.
If an error is detected, the amplitude of the jitter is reduced by one decrement, and this value becomes the jitter
tolerance at that particular frequency. The network analyzer then increases the frequency to the next data
point and repeats the process of increasing the amplitude. The Jitter Tolerance test results in a graph showing
the LIU performance relative to the mask outlined in ITU-G.823. The LIU curve must be above the mask at all
frequencies in order to comply with industry specifications.
