For the MMI terminal to be able to communicate to the Lineside T1 card, the
interface characteristics must be set to the following:

Software configuration
Although much of the architecture and many of the features of the Lineside
T1 card differ from the analog line card, the Lineside T1 card has been
designed to emulate an analog line card to the CS 1000 software. Because
of this, the Lineside T1 card software configuration is performed the same
as two adjacent analog line cards.
All 24 T1 channels carried by the Lineside T1 card are individually
configured using the Analog (500/2500-type) Telephone Administration
program LD 10. Use

10 service change instructions.
The Lineside T1 card circuitry routes 16 units (0-15) on the motherboard and
eight (0-7) units on the daughterboard to 24 T1 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 the Lineside T1 card is installed
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 T1 channel number must be
cross-referenced to the corresponding card unit number. This mapping is
shown in
