Installation and Configuration
Installation and configuration of the LEI consists of six basic steps:
Step Action
1 Configure the dip switches on the LEI for the call environment.
2 Install the LEI into the selected card slots.
3 Cable from the I/O panel to the LTU, MMI terminal or modem
(optional), external alarm (optional), and other LEIs for daisy
chaining use of MMI terminal (optional).
4 Configure the MMI terminal.
5 Configure the LEI through the CS 1000 software and verify self-test
results.
6 Verify initial E1 operation and configure MMI (optional).
Steps 1-5 are explained in this section. Step 6 is covered in
"Man-Machine E1 maintenance interface software" (page 292) .
Installation and configuration of the ELEI follows the same steps.
If enhanced functionality is required, then one additional step is
required:
7 The Meridian 1 line unit(s) associated with the lineside E1 must
be programmed for wireless operation (set WTYP=DECT, and
WRLS=Yes in LD 10) in non–concentrated mode. Refer to Software
Input/Output Reference — Administration (NN43001-611) details
on LD 10.

Dip switch settings
Begin the installation and configuration of the LEI by selecting the proper dip
switch settings for the environment. The LEI contains two dip switches, each
containing eight switch positions. They are located in the upper right corner
of the motherboard circuit card as shown in
Figure 59 "LEI card - E1 protocol
dip switch locations" (page 276) . The settings for these switches are shown
in Table 115 "LEI card - Switch 1 dip switch settings" (page 277) through
Table 118 "LEI card - E1 Switch 2 (S2) dip switch settings" (page 279) .
