ATM is not available.
Sorry for forgetting to say sth.
3640 is also the "hub",cause each 3640 should get connected with several
2620
in each area by FR.
SO there are 3 levels ,7507-3640-2620.
For connection with 2620 ,i plan to use NM-4T on 3640.
These 2620 are allocated different speed,some is 2M ,some is 64K maybe ,or
128k.
I want to use one port on 4T for several low speed links ,one specific port
for
a 2M-link 2620.This will be a mixed config,point to multipoint and point to
point .
is this applicable or reasonable?

Any recommendations are appreciated.
