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 284) .
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.
