Installation and Configuration

Installation and configuration of the LEI consists of six basic steps:

1Set the dip switches on the LEI for the 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 Release 4.0 software and verify self-test results.

6Verify 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” on page 272.

Installation and configuration of the ELEI follows the 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=Yes in LD 10) in non–concentrated mode. Refer to Software Input/Output: Administration (553-3001-311) details on LD 10.
