The biggest drawback in my opinion is a lack of NFAS knowledge on the telco's part typically. They're not used to seeing NFAS and hence not used to supporting NFAS when there are problems. We've removed all but 1 NFAS group from our network because of a lack of support from the telcos. In my opinion you should have a primary and a backup D channel. Else if you loose the span with the D-channel you're going to drop everyone...6 PRI's worth in your case. Ask them about having a primary and a backup D channel. Maybe they'll change their quotas on the number of PRI you can associate. I have had a fully loaded chassis in the past with a primary and a backup D channel. Also....you can have more then 1 NFAS group in a chassis. You just have to make sure their ID's are different.

Arc 5.3.2 DSP 3.5.100 (V.92/V.44) o Any big drawbacks / bugs with the TC1000 NFAS support? Switch type is ess o If your telco limits the number of PRI's that can be associated with one D Channel can you only put that number of PRI's on a chassis? For example, if my Telco says "six PRI's max on a D Channel" can I put twelve PRI's into one chassis and run NFAS on two D Channels, one per each set of six PRI's? Or am I stuck with only being able to put six PRI's on that entire chassis?
