8kHz Clock Output Reference
This pin is an output reference of 8kHz based on the MCLKIN
input. Therefore, the duty cycle of this output is determined by the
time period of the input clock reference.

External Oscillator Select
For normal operation, this pin should not be used, or pulled “Low”.
This pin is internally pulled “Low” with a 50k

Loss of Power for E1 Only
This is a Loss of Power pin in the E1 application only. Upon
detecting LOP in E1 mode, the device will automatically transmit
the Sa5 and Sa6 bit to a different pattern, so that the Receive ter-
minal can detect a power failure in the network.
Please see register 0xn131 for the Transmit SA control.
