78P2352 Dual Channel OC-3/STM1-E/E4 Line Interface Unit
ELECTRICAL SPECIFICATIONS (continued)
RECEIVER JITTER TOLERANCE
The 78P2352 is compliant with all relevant jitter tolerance specifications shown in Figures 15, 16. STS-3/OC-3
jitter tolerance specifications are in ANSI T1.105.03-1994 and Telcordia GR-253-CORE. STM-1 (optical) jitter
tolerance specifications are in ITU-T G.813, G.825, and G.958.
STM-1e (electrical) jitter tolerance
specifications are in ITU-T G.825. E4 specifications are found in ITU-T G.823. Receive jitter tolerance is not
tested during production test.
