| This is the first, and most critical, section of operation. Once you get the data path
right the codecs will generally take care of themselves. These instructions refer to
the ADTRAN ISU-128 (shown here) which, at NPR, is the
terminal adapter used for the RE-660/661.
The ISU-2x64
is used at NPR with CDQ-1000 and the CDQ-2000 codecs. It differs only slightly from the
ISU-128.
