Overview
The ACCULINK Model 3151 CSU and Model 3161
DSU/CSU are shipped without cables. Various
interconnecting cables are available from AT&T
Paradyne. These cables have an AT&T Paradyne feature
number assigned to them (see Appendix C, Equipment
List). Cables that are listed, but have no feature number,
must be customer supplied. This appendix describes the
cable pin assignments for both AT&T Paradyne cables
and customer-supplied cables. You can use this
information should you need to build your own cables.
Unless otherwise noted, the interface connections
apply to both Models 3151 and 3161.
