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
“Performance counters and reporting” on page 292.
E1 Verification and Fault Isolation Testing
The MMI enables various tests to be performed that either verify that the E1
is working adequately, or help to isolate a problem to the LEI, the E1 link, or
the CPE. For descriptions of all of these tests and instructions on how to run
them, see “Testing” on page 295.
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 L <address>, where the four-digit address is a combination of the
two-digit address of the IPE shelf as set by dip switch positions on the card
Switch 1, positions 3-6, plus the address of the card slot the motherboard
occupies. See Table 96 on page 260.
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.
The MMI prompts for a password. The password is “LEILINK,” and it must
be typed in all capital letters.
After logging in, the prompt looks like this:
