Nortel Networks Circuit Card 311 - Manual (Page 219)

Installation and configuration 219
For the MMI terminal to be able to communicate to the Lineside T1 card, the
interface characteristics must be set to the following:
• Speed – 1200 or 2400 bps, depending on the setting of switch position 1
of Switch 1
• Character width – 8 bits
• Parity bit – none
• Stop bits – one
• Software handshake (XON/XOFF) – off
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
Table 101 "DX-30 to T1 time slot mapping" (page
219) to determine the correct unit number and the technical document
Software Input/Output Reference — Administration (NN43001-611) for LD
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
Table 101 "DX-30 to T1 time slot mapping" (page 219) .
