Installation and Configuration
Installation and configuration of the LEI consists of six basic steps:
1 Set 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
