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:
