2.9.4.3 Output Enable  
The bipolar analog output XTIP/XRING can be enabled or disabled using the  
XOE pin. This feature allows switching between multiple XTIP/XRING outputs  
that are tied together.  
2.9.5 Pulse Imbalance  
In any window of 17 consecutive primary rate cycles, the maximum variation in  
pulse amplitude in the absence of 60 Hz variations is <200 mV. The maximum  
variation in pulse width at half amplitude is <20 ns.
