PC card slots
The ITG-P card has one faceplate PC card slot, designated drive A. The
PC card slot is used for optional maintenance (backup and restore). The
ITG-P card also has one unused inboard slot, designated drive B. The PC
card slots support PC-based hard disks (ATA interface) or high-capacity PC
flash memory cards.
Maintenance Display
A four character, LED-based, dot matrix display shows the maintenance
status fault codes and other card state information.
RS-232 Maintenance Port
The ITG-P card faceplate provides a female DIN-8 serial maintenance port
connection (labeled Maint Port). An alternative connection to the faceplate
serial maintenance port exists on the NTMF94EA I/O panel breakout cable.
Do not connect maintenance terminals or modems to the faceplate and I/O
panel DB-9 male serial maintenance port at the same time.
Backplane interfaces
The backplane connector provides connection to the following:
• ELAN interface card
• TLAN interface card
• alternate connection to the serial maintenance port DS-30X
• Card LAN interfaces
DS-30X voice/signaling
DS-30X carries Pulse Code Modulation (PCM) voice and proprietary
signaling on the backplane between the ITG-P card and the SSC.
Card LAN
Card LAN carries card polling and initialization messages on the backplane
between the ITG-P card and the SSC.
Assembly description
The ITG-P card assembly consists of a two-slot motherboard/daughterboard
