Randy,
I agree with your findings. If you are only scanning one scanlist and that scanlist only is associated with one TSYS object that is multisite STAT, it will go through each active CC and sample it. However, if you have more than one scanlist enabled or a scanlist with multiple TSYS objects and or a multisite STAT TSYS object and some conventional objects, it will only check one CC in the multisite STAT TSYS during each pass.
I don't particularly mind how that functions, but I'll give you a scenario that I don't like:
scanlist 1: about 10 conventional freqs
scanlist 2: associated with a TSYS object set up multisite STAT
If you enable both scanlists, scanlist 1 effectively gets prioritized and the multisite STAT TSYS object essentially doesn't get fully checked on each pass... i.e, the scanning happens like this:
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, first multisite CC
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, second multisite CC
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, third multisite CC
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, fourth multisite CC
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, fifth multisite CC
scanlist 1, freq 1 through scanlist 1, freq 10
TSYS object, sixth multisite CC
So if you have 6 site CCs in a multisite STAT TSYS object, then it takes 6 full scan runs to check all of that multisite TSYS object, and at the same time the conventional scanlist 1 was checked thoroughly 6 times
Similarly, if you only have one scanlist and it consists of TGRP objects associated with a multisite STAT TSYS and CONV objects, then by the time the multisite STAT system gets totally scanned, each of the conventional objects have essentially been checked n * (# of active CC's in multisite STAT CC) times.
The only time that a multisite STAT TSYS object works like one would expect it to work (sequentially scanned, one right after the other), is when the scanlist associated with it is the only scanlist being scanned and that scanlist does not have any other objects in it besides TGRP objects associated with the TSYS.
So, if you want a multisite STAT setup to receive "equal time" being thoroughly scanned as other scanlists, you need to instead end up setting it up as (in my case) 6 separate standard TSYS objects (multisite off) with the frequencies for each site in its own TSYS object. In that way, the actual system with the multiple sites gets completely scanned during each scan run.
Sure, if you do it as described in the paragraph directly above, it seems a lot slower - in fact, is a lot slower - it is as slow as one would expect it to be if you were checking multiple site CC's per scan run. But, on the other hand you're multiple sites also got equal scanning time per scan run whereas they do not otherwise.
