SIX CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER

This feature is used for monitoring the transmit line for occurrence of fault conditions such as a short circuit on
the line or a defective line driver. To activate this function, connect MTIP_n pins to the TTIP_n lines via a 270
resistor and MRing_n pins to TRing_n lines via 270
resistor as shown in Figure 25.
Transmit Drive Monitor
When the MTIP_n and MRing_n are connected to the TTIP_n and TRing_n lines, the drive monitor circuit
monitors the line for transitions. The DMO_n (Drive Monitor Output) will be asserted “Low” as long as the
transitions on the line are detected via MTIP_n and MRing_n. If no transitions on the line are detected for 128
± 32 TxClk_n periods, the DMO_n output toggles “High” and when the transitions are detected again, DMO_n
toggles “Low”.

:
The Drive Monitor Circuit is only for diagnostic purpose and does not have to be used to operate the transmitter.
4.7
Transmitter Section On/Off
The transmitter section of each channel can either be turned on or off. To turn on the transmitter, set the input
pin TxON to “High” and write a “1” to the TxON_n control bit. When the transmitter is turned off, TTIP_n and
TRing_n are tri-stated.

This feature provides support for Redundancy.
To permit a system designed for redundancy to quickly shut-off the defective line card and turn on the back-up line
card, writing a “1” to the TxON_n control bits transfers the control to TxON pin.
