INVERTING DATA SIGNALS
The Fractional Interface Card allows you to invert the SD and RD signals.
Some protocols, such as X.25, use this data inversion to satisfy the ones
density requirement of T1 lines operating in AMI mode. Unless specifically
required by a protocol, do not use data inversion.
There are two settings for the Data Inversion option:
• OFF leaves SD and RD signals in their normal, non-inverted, state.
• ON inverts the SD and RD signals.
To invert the SD and RD signals:
1 Press Escape until CAMPUS RS I/F: FRAC displays.
2 Press Next until DATA PORT CONFIG & STATUS displays, then press
Enter. RATE MULTIPLIER displays.
3 Press Next until INVERT DATA displays, then press Enter. The current
invert data setting displays.
4 Press Next until the desired setting displays, then press Enter.
