Loopback Variation on OTs
Each OT card in the system contains hardware designed to support various client signal
types, line rate and applications specific to each pack. Thus, the transmission path
(including clock architecture) through each card is different. The following diagrams
illustrate the variation of loopbacks on 1830 PSS OTs.
