Software Configuration

Although much of the architecture and many features of the LEI card are different from the analog line card, the LEI has been designed to emulate an analog line card to the CS 1000 Release 4.0 software. Because of this, the LEI software configuration is the same as for two adjacent analog line 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 99 to determine the correct unit number and Software Input/Output: Administration (553-3001-311) 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 will need to be cross-referenced to the corresponding card unit number. This mapping is shown in Table 99.
