The MMI retains E1 performance statistics for the current hour, and for each
hour for the previous 24. For descriptions of these performance error counters
and instructions on how to create a report on them and clear them, see

E1 Verification and Fault Isolation Testing
The MMI enables various tests to be performed that either verify that the E1

them, see “Testing” on page 307.
Login and Password
The MMI can be accessed through any TTY, PC running a terminal emulation
program, or modem. After installing the MMI terminal and card cables, the
MMI can be configured.
For single-card installations, it is accessed by entering L<CR> to login.
For multiple-card installations connected in a daisy chain, it is accessed by
entering

For example, to login to a card located in shelf 13, card slot 4, type:
L 13 4 <CR>
Spaces are inserted between the login command (L), the shelf address, and the
card slot address.
