i don`t mean to be rude ,but i was essential correct..
if you set the bandwidth command to 64k and you have a CIR of 128K yo will
only get 64K...But as my good friends have pointed out the default is
1.544kb......but i was just trying to make that point stand out that it`s
the serivce provider who makes the call about the info rate...
I`m sorry if i`m bieng ANAL about this i just wanted myself to be clear..
best regards
steve
