Cabling The Lei Card; Cabling From The I/O Panel With The Nt5D35Aa Or Nt5D36Aa Lineside E1 I/O Cable - Avaya Nortel Communication Server 1000 Reference

NT5D33 and NT5D34 Lineside E1 Interface cards
Vintage levels cabling 16 ports:
For modules with vintage levels that cable 16 ports to the I/O panel, the LEI can be installed
into the card slot pairs shown in the following card slots:
Available:
LEIs must not be installed into the following card slot pairs:
Restricted:
If the LEI must be installed into one of the restricted card slot pairs, rewire the IPE module card
slot to the I/O panel by installing an additional NT8D81 cable from the LEI motherboard slot to
the I/O panel, and re-arranging the three backplane connectors for the affected card slots. This
permits the connection of the NT5D35AA or NT5D36AA LEI card carrier and maintenance
external I/O cable at the IPE and CE module I/O panel connector for card slots that are
otherwise restricted.
Alternatively, all LEI connections can be made at the main distribution frame instead of
connecting the NT5D35AA or NT5D36AA LEI card external I/O cable at the I/O panel. This
eliminates these card slot restrictions.

Cabling the LEI card

After the dip switches are configured and the LEI installed into the selected card slots, the LEI
can be cabled to the LTU equipment, the MMI terminal or modem (optional), an external alarm
(optional), and other LEIs for daisy chaining use of the MMI terminal (optional).
The LEI is cabled from its backplane connector through connections from the motherboard
circuit card only to the I/O panel on the rear of the IPE module. No cable connections are made
from the daughterboard circuit card. The connections from the LEI to the I/O panel are made
with the NT8D81AA Tip and Ring cables provided with the IPE module.
Cabling from the I/O panel with the NT5D35AA or NT5D36AA
lineside E1 I/O cable
In a twisted-pair E1 installation, make the connection from the I/O panel to the E1 link and
other external devices with the NT5D35AA lineside E1 I/O cable.
This cable consists of a 25-pair amphenol connector (P1) on one end which plugs into the I/O
panel. The other end has four connectors:
1. a DB15 male connector (P2), which plugs into the E1 line
2. a DB9 male connector (P3), which plugs into an external alarm system
