Of course one solution doesn't fit everything but most likely would in
the case at bar (providing it is truly an analog system).

T1 cards are dirt cheap and channel banks are too.  They are also
modular, so if a card goes out, you lose 4 extensions.  If the chassis
goes out, then you lose all but it is all solid state.  I mean this
stuff is the mainstay of telephony.

A SIP FXS box will obviously have a substantial lower mean time
between failures.  Look it up.

What brand did you see fail and what failed?  I have only had cards
blow out and that is EXTREMELY rare.
