E1 Performance Counters and Reports
The MMI maintains performance error counters for the following E1
conditions: errored seconds, bursty seconds, unavailable seconds, framer-slip
seconds, and loss-of-frame seconds. The MMI retains E1 performance
statistics for the current hour, and for each hour for the previous 24. For
descriptions of each of these performance error counters and instructions on
how to create a report of them and clear them, see "Performance counters and
reporting" on page 184.
E1 Verification and Fault Isolation Testing
The MMI allows you to perform various tests and will either verify that the
E1 is working adequately, or help you to isolate a problem to the LEI, the E1
link, or the CPE equipment. For descriptions of all of these tests and
instructions on how to run them, see "Testing" on page 186.
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, you
are ready to configure the MMI. 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, see Table 40, "Line-side
E1 card—NT8D37 IPE Module vintage level port cabling," on page 152, plus
the address of the card slot the motherboard occupies. For example, to login
to a card located in shelf 13, card slot 4, you would type L 13 4 <CR>. Spaces
are inserted between the login command (L), the shelf address, and the card
slot address.
The MMI will now prompt you for a password. The password is
"LEILINK," and it must be typed in all capital letters.
After you have logged in, the prompt will look like this:
LEI::> (for single-card installations)
LEI::ss cc> (for multi-card installations, where ss represents the shelf
address and cc represents the card slot address.)
