264 NT5D33 and NT5D34 Lineside E1 Interface cards
•NT5D33AC/NT5D34AC– Enhanced Lineside E1 Interface (ELEI) cards
The ELEI card is similar to an LEI card, but has beenenhanced 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 anyCAS+ 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:

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 by10 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
