Parameter Specifications
Storage temperature –50 to + 70 C (–58 to 158 F), ambient
Storage humidity 5% to 95% RH (non-condensing)
Installation and Configuration
Installation and configuration of the LEI consists of six basic steps:
Step Action
1Configure the dip switches on the LEI forthe call environment.
2Install the LEI into the selected card slots.
3Cable 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).
4Configure the MMI terminal.
5Configure the LEI through the CS 1000 software and verify self-test
results.
6Verifyinitial E1operation 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 followsthe same steps.
If enhanced functionality is required, then one additional step is
required:
7The Meridian 1 line unit(s) associated with the lineside E1 must
be programmed for wireless operation (set WTYP=DECT,and
WRLS=Yesin 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 configurationof the LEI by selecting the proper dip
switch settings forthe environment. TheLEI containstwo 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 Table115 "LEI card - Switch 1 dip switch settings" (page 277) through
