RE: tx-?-limit

Greetings Andrew & Andy, respectively

Unfortunately, the link offered was one of those that was not helpful to me.
Per my initial post, I already read all the ATM-PA stuff.

My questions are:

1) Why is the tx-queue-limit command automagically added?
    (translation: when you issue tx-ring-limit this phantom command appears)

2) Why is the tx-queue-limit command unavailable directly?
    (translation: it's not there in the command line)

3) What exactly do these commands do on non-PA interfaces?
    (translation: I am a little slow and I still don't get it)

Thanx!

Looking for other ways to tweak interfaces:

Rack1R1(config-if)#tx?
tx-ring-limit
Rack1R1(config-if)#tx-ring-limit 123
Rack1R1(config-if)#end
Rack1R1#sh run | b interface Serial0/0
interface Serial0/0
no ip address
encapsulation frame-relay
tx-ring-limit 123
tx-queue-limit 123

(note: tx-queue-limit is automagically added to the config)

I tried looking this up only to find some ATM-PA references that did not
clarify.
...Same commands (or lack thereof) appear to be true/available on ethernet,
etc...
I hope am clear in thinking this has nothing to do with the hold-queue in |
out command
(which defines the maximum # of input and output queues as I understand it)

That said, I am curious just what this does, if anything
And why we cannot do just a queue-limit?
(since that command does not exist??)
