Hi,
here works many E1-connectoins (PRI dial-connectoins) from different
routers (3620 or 26xx) with e1 interfaces to AS5400 (with only e1) and
an C7509 with e1-interfaces.
For many routers that works properly but on some whe have many problems
with the performance. In the output for show ppp multlink, i can see on
this routers many lost fragments. Have you some tips for me?
Here is a smpleconfig:
