Introduction
Two vintages of NT5D33 and NT5D34 cards are supported:
•
NT5D33AB/NT5D34AB – standard Lineside E1 Interface (LEI) cards
The LEI card is an IPE line card that provides an all-digital connection
between E1–compatible terminal equipment (such as a voice mail
system) and CS 1000E, CS 1000M, or Meridian 1.
The LEI interfaces one E1 line, carrying 30 channels, to the CS 1000E,
CS 1000M, or Meridian 1, and emulates an analog line card to the
system software. Each channel is independently configured by software
control in the Analog (500/2500-type) Telephone Administration program
LD 10. The LEI also comes equipped with a Man-Machine Interface
(MMI) maintenance program, which provides diagnostic information
regarding the status of the E1 link.
