INTRODUCTION
This appendix describes the procedures to be used in performing acceptance testing of the Total Access
MX2800 STS-1 Multiplexer. It is assumed that the MX2800 has already been installed, powered-up, and
cabled to the DSX-1 and STS-1 cross connects, according to the specifications described in the MX2800

Supply Units (PSU) may be installed; one or two Controller Card Units (CCU) may be installed. One of
each is required for non-redundant operation (two of each for full redundancy). Refer to
Installing Cards
on page 2-16 for instructions on removing the front panel and identifying the cards.
