256 NT5D33 and NT5D34 Lineside E1 Interface cards
The ELEI card is similar to an LEI card, but has been enhanced
to allow the capability of transporting caller information using the
proprietary signaling interface Channel Associated Signaling (CAS+).
ELEI cards can operate in one of two modes: LEI mode, or enhanced
(ELEI) mode. In LEI mode, this card is fully compatible with, and
provides the same functionality as, the standard LEI card. In ELEI
mode, this card can be connected to any CAS+ compliant systems.
This includes wireless server hosting Digital Enhanced Cordless
Telephones (DECTs), voice response units, voice messaging systems,
and trading turret systems (used in stock market applications).
More information regarding CAS+ can be obtained through Nortel
Development Partner program.
Note: As the ELEI cards provide identical functionality to LEI cards,
references to LEI cards in this chapter also apply to ELEI cards
unless specified otherwise.
Install the NT5D33 version of the LEI/ELEI card in the NT8D37 IPE
module.
Install the NT5D34 version of the LEI/ELEI card in:
• the NTAK11 Cabinet
•
the NTAK12 Expansion Cabinet
• the NT1P70 Small Remote IPE Main Cabinet
• the NTAK12 Small Remote IPE Expansion Cabinet
Physical description
The LEI mounts in two consecutive card slots in the IPE shelf. It uses 16
channels on the first slot and 14 channels on the second. The LEI includes
a motherboard (31.75 by 25.40 cm (12.5 by 10 in) and a daughterboard
(5.08 by 15.24 cm (2 by 6 in).
Card connections
The LEI uses the NT8D81AA Tip and Ring cable to connect from the IPE
backplane to the 25-pair Amphenol connector on the IPE Input/Output (I/O)
panel. The I/O panel connector connects to a E1 line, external alarm and
an MMI terminal or modem, using the NT5D35 or NT5D36 lineside I/O
cable available from Nortel.
Faceplate
The LEI faceplate is twice as wide as the other standard analog and digital
line cards. It occupies two card slots. The LE1 faceplate has four LEDs.

LEI card - faceplate" (page 257) (IPE version), and Figure 55 "NT5D34AB
LEI card - faceplate" (page 258) (Cabinet system).
