Synchronous Microprocessor Clock/Automatic Transmit All Ones
Hardware Mode
This pin is used select an all ones signal to the line interface through TTIP/TRING any
time that a loss of signal occurs. This feature is avaiable in Host mode by program-
ming the appropriate global register.

Interrupt Output
Host Mode
This signal is asserted "Low" when a change in alarm status occurs. Once the status
registers have been read, the interrupt pin will return "High". GIE (Global Interrupt
Enable) must be set "High" in the appropriate global register to enable interrupt gen-
eration.
N
OTES
:
1.
This pin is an open-drain output that requires an external 10K
pull-up
resistor.

This pin has an internal PULL-DOWN 50k
resistor

T1 Master Clock Input
This signal is an independent 1.544MHz clock for T1 systems with accuracy better
than ±50ppm and duty cycle within 40% to 60%. MCLKT1 is used in the T1 mode.
N
OTE
:
All channels must operate at the same clock rate, either T1, E1 or J1. This
