NT5D33 and NT5D34 Lineside E1 Interface cards
553-3001-211 Standard 3.00 August 2005
provides alarm notification, E1 link performance reporting, and fault
isolation testing. The interface is accessed through connections from the I/O
panel to a terminal or modem. Multiple cards (up to 64) can be served through
one MMI terminal or modem by linking the LEIs through a daisy chain.
The MMI is an optional feature, since all E1 configuration settings are
performed through dip switch settings or preconfigured factory default
settings. Available MMI commands, and their functionality, are discussed
in-depth in “Man-Machine E1 maintenance interface software” on
page 284
.
ELEI additional functionality
As mentioned earlier, ELEI cards are enhanced to allow CAS+ compliance,
as shown in Figure 43. This enhancement provides several additional benefits
for systems with ELEI cards installed.
Note:
MDECTS and ELEI (operating in enhanced mode) cannot be
configured on the same system.

CAS+ compliance
Key Benefits of using CAS+ signaling (ELEI mode) over traditional A/B bit
signaling (LEI mode) include:
1
Calling Line ID Presentation (CLIP)
When an incoming call over the TDM/IP network or a CS 1000
originated call is directed towards the CAS+ compliant system, Calling
Line ID can be provided over the CAS+ interface. This is assuming that
the incoming call has the CLID without any presentation restrictions.
