Nortel Networks Circuit Card 311 - Manual (Page 288)

288 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
Table 123 "Card unit number to E1 channel mapping" (page 288) to
determine the correct unit number and 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 would
reside in card slot 1. In order to configure the terminal equipment through
the switch software, the E1 channel number needs to be cross-referenced
to the corresponding card unit number. This mapping is shown in
Table 123
"Card unit number to E1 channel mapping" (page 288) .
