I have a TDM400P (configured with 4 FXO cards) in a box that was working fine from POTS lines extracted from a Lightspan via DSC's channel bank, but when I switched over to using an Adtran 616 (weird little box, takes an SHDSL circuit in that splits out 16 analog lines via an amp connector) the card no longer seems to be able to detect ringing. I've tried upping the rxgain with no noticable effect. Does anyone else have this piece of hardware working with a TDM400P that could shed some light on this? -- Jason T.
