Circuit Card Description and Installation
Installation and Configuration
Installation and configuration of the LEI consists of six basic steps:
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 Release 4.5 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” on
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:
Administration (553-3001-311) details on LD 10.
