Installation and configuration 219For the MMI terminal to be able to communicate to the Lineside T1 card, theinterface characteristics must be set to the following:• Speed – 1200 or 2400 bps, depending on the setting of switch position 1of Switch 1• Character width – 8 bits• Parity bit – none• Stop bits – one• Software handshake (XON/XOFF) – offSoftware configurationAlthough much of the architecture and many of the features of the LinesideT1 card differ from the analog line card, the Lineside T1 card has beendesigned to emulate an analog line card to the CS 1000 software. Becauseof this, the Lineside T1 card software configuration is performed the sameas two adjacent analog line cards.All 24 T1 channels carried by the Lineside T1 card are individuallyconfigured using the Analog (500/2500-type) Telephone Administrationprogram LD 10. Use Table 101 "DX-30 to T1 time slot mapping" (page219) to determine the correct unit number and the technical documentSoftware Input/Output Reference — Administration (NN43001-611) for LD10 service change instructions.The Lineside T1 card circuitry routes 16 units (0-15) on the motherboard andeight (0-7) units on the daughterboard to 24 T1 channels. The motherboardcircuit card is located in the left card slot, and the daughterboard circuit cardis located in right card slot. For example, if the Lineside T1 card is installedinto card slots 0 and 1, the motherboard would reside in card slot 0 and thedaughterboard would reside in card slot 1. In order to configure the terminalequipment through the switch software, the T1 channel number must becross-referenced to the corresponding card unit number. This mapping isshown in Table 101 "DX-30 to T1 time slot mapping" (page 219).Table 101DX-30 to T1 time slot mappingItem TN T1 Channel NumberMotherboard 0 1Motherboard 1 2Motherboard 2 3Motherboard 3 4Motherboard 4 5Nortel Communication Server 1000Circuit Card ReferenceNN43001-311 01.04 StandardRelease 5.0 23 May 2008Copyright © 2003-2008, Nortel Networks.
