My suggestions for B8ZS zero code suppression - YES is based upon all MSDN links on my network - which are on D4/AMI circuits.
From Mitel docs: Zero Code Suppression is a method of reducing timing errors by suppressing all-zero codes and replacing them with another bit pattern. Both ends of the link must specify the same type of zero code suppression. Default value is "Yes"

becca1jane is correct, and as she pointed out earlier both sides must be set to YES. What did the Mitel logs and DT read show? What model CSU are you using?

I was able to find some MSDN links on our network that were set to B8ZS zero code suppression - NO on both sides. Otherwise all descriptors are similar other than opposites ends of each link being set to A/B for message control.

You mentioned you are clocking to the CO PRIs at each location - if you do a dt r on the PRIs are you seeing any errors at the time of the activity switch? Hope this doesn't sound stupid, but are both PBX's in the same timezone, or atleast in different timezones so that 1:15 on one PBX is not equal to 2:15 on the other? And is the time set correctly on each?

What is the possibility of putting your own cable across the street, at least temporarily? Eliminate every bit of possible telco as a trouble source. I've done this twice, with P-P T1, and the problems ALL dissappeared! And companies were so happy with low cost, they put in a permanent link. Remember, arial may not be possible, but boring under the street probably is! Just make sure whoever does the job is bonded AND INSURED! John C. (Not Garand)

Your last CSU alarm post would indicate the problem is with your carrier. The 2000 on shows a Yellow alarm. You could double check with one of the guru’s in the T1 forum.
NI AIS-Active Out Of Frame - Active Red - Active
T1 Yellow - Active
Network Interface Alarms
AIS Alarm Unframed all-ones received at NI Out of Frame No framing pattern sync at NI Red Alarm LOS (loss of signal)/out of frame (OOF) causing red alarm at NI
T1 terminal Interface Alarms
Yellow Alarm Receiving yellow alarm pattern from T1
