not sure what level of dtl you want its quite straight fwd
It varies depending on the chasis but in general
there are T1 in and T1 out DB-15's for each T1 circuit you want to echo
cancel.

A straight T1 rj-45 cable goes to the channel bank other end is db-15 in to
Tellab
then a T1 X over goes from the Tellab db-15 out to the T100p card

Then there are external Mode and Chan switchs that allow you to configure
the T1
circuit  (the line bld, framing, and coding/signaling), and then other
setting to allow
channels FXO/FXS LS, GS and enable echo cancel channel by channel,
I do it for all fxs/fxo ports and turn ALL * echo cancel in zapata OFF..
