This is because most vendors still believes that T1 circuits are provision
as D4/AMI..Digital Link Encore csu/dsu by default has it setup as
ESF/B8ZS.
I'm evaluating the new cisco 2524 with internal CSU/DSU, and it looks
like the default is ESF/B8ZS on this box too. Maybe there's hope for
the vendors catching up with reality on this front afterall.
Anyone have experience mixing different vendor CSU/DSUs and getting
things like remote loopback to work?
