Signal Name:
Signal Description:
Signal Type:
Via the EIC control bit in the T3/E3 Error Insert Control Register (Section 5.2), the DS3112 can be
configured to use this asynchronous input to cause errors to be inserted into the transmitted data stream.
A zero to one transition on this input causes the device to begin the process of causing errors to be
inserted. This signal must be returned low before any subsequent errors can be generated. If this signal is
not used, then it should be tied low.
