Model 3196RC T-DAC User Manual 1 • Introduction
System timing
The iDSL T-DAC's system timing may be derived from an internal clock from an on-board chip, a CPE iDSL
modem, a network clock from one of the T1/E1 WAN ports, or an external 64-kHz BITS (building integrated
timing supply) reference clock.
The system timing is configured through the NMS.
