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.

• NT5D33AC/NT5D34AC – Enhanced Lineside E1 Interface (ELEI) cards
