This does not sound right. If it is 2 PRIs then it should be 46 channels
(or 47 channels if sharing a D channel). A quick google search indicates
that these channel banks can deal with PRI in a drop and insert mode
only, not for termination. (I use Adtran channel banks which are not PRI
so I may be confused here).
