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 109 "Card unit number to E1 channel mapping" (page 280)
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 109 "Card unit number to E1 channel mapping"
.
