Avaya Nortel Communication Server 1000 Reference page 218

NT5D33 and NT5D34 Lineside E1 Interface cards
All 30 E1 channels carried by the LEI are individually configured using the analog (500/2500-
type) Telephone Administration program LD 10. Use
mapping on page 218 to determine the correct unit number, and refer to Software Input/Output
Reference — Administration (NN43001-611) for LD 10 service-change instructions.
LEI circuitry routes 16 units (0 – 15) on the motherboard and 14 (0 – 13) units on the
daughterboard to 30 E1 channels. The motherboard circuit card is located in the left card slot,
and the daughterboard circuit card is located in right card slot. For example, if installing the
LEI into card slots 0 and 1, the motherboard would reside in card slot 0 and the daughterboard
in card slot 1. To configure the terminal equipment through the switch software, the E1 channel
number must be cross-referenced to the corresponding card unit number. This mapping is
shown in Table 95: Card unit number to E1 channel mapping
