Monitor Ring Input - Channel 0:
Monitor Ring Input - Channel 1:
The bipolar line output signal from TRING_n is connected to this pin via a 270
resistor to check for line driver failure.
N
OTE
:
This pin is internally pulled "High".

Monitor Tip Input - Channel 1:
The bipolar line output signal from TTIP_n is connected to this pin via a
270-
ohm resistor to check for line driver failure.

:
This pin is internally pulled "High".

Drive Monitor Output - Channel 0:
Drive Monitor Output - Channel 1:
If MTIP_n and MRING_n has no transition pulse for 128 ± 32 TxCLK_n cycles,
DMO_n goes “High” to indicate the driver failure. DMO_n output stays “High”
until the next AMI signal is detected.

Receive Loss of Signal Output Indicator - Channel 0:
Receive Loss of Signal Output Indicator - Channel 1:
This output pin toggles "High" if the receiver has detected a Loss of Signal Con-
dition.
The criteria for declaring /clearing an LOS Condition depends upon whether it is
operating in the E3 or STS-1/DS3 Mode.

RLOL_0
RLOL_1
O
Receive Loss of Lock Output Indicator - Channel 0:
Receive Loss of Lock Output Indicator - Channel 1:
This output pin toggles "High" if a Loss of Lock Condition is detected. LOL
(Loss of Lock) condition occurs if the recovered clock frequency deviates from
the Reference Clock frequency (available at either E3CLK or DS3CLK or STS-
1CLK input pins) by more than 0.5%.

RXA
****
External Resistor of 3 K
± 1%.
Should be connected between RxA and RxB for internal bias.

****
External Resistor of 3K

In-Circuit Test Input:
Setting this pin "Low" causes all digital and analog outputs to go into a high-
impedance state to allow for in-circuit testing. For normal operation, tie this pin
"High".
