Section 4, Status MX2800 M13 Multiplexer User Manual
5. DS2 STATE
This field displays the current state of each of the seven DS2s. Possible states are listed in Tab le 4-8.
6. T1/E1 STATE
This field displays the current state of the individual T1s or E1s. Possible states are listed in Table 4-9.
NOTE
A DS2 can be divided into either three E1s or four T1s. Therefore, when
dealing with an E1 configuration, some of the fields in the
T1/E1 State
menus do not apply (and display nothing).

This selection is used to remotely turn off an active alarm. It is the software equivalent of the ACO button
as described in ACO Buttons on page 2-15.
