Operation of the 9522A

After the proper set up procedures have been accomplished, the modem should communicate correctly with
the controller and the other modems in the network. In the event of problems, make use of the extensive
array of indicators available on the 9522A for troubleshooting. Table 11 below provides additional information
about the Indicators.

Position Function
On when the unit is powered by DC input voltage. Blinks when operating from the Gel
N/A
Cell Battery.
Indicates that it is properly receiving a "BERT" signal transmitted by another unit
N/A
(only valid during a BERT Test).
Indicates one of three conditions on the Primary Port: 1. RS232 Electrical Anti-
N/A Streaming timeout 2. If the unit is in Master Fault Tolerant mode and a break has
been sensed in the ring. 3. RX1 or RX2 Optical Anti-Stream Condition
Indicates one of two conditions on the SECONDARY Port: 1. RS232 Electrical Anti-
N/A
Streaming timeout 2. RX1 or RX2 Optical Anti-Stream Condition
Right Indicates data input to Pin 2 of the Primary Data I/O Port.
Right Indicates data output from Pin 3 of the Primary Data I/O Port.
Indicates a true CTS output from Pin 5 of the Primary Data I/O connector in RS232
Right
Mode
Right Indicates data input to Pin 2 of the Secondary Data I/O Port.
Right Indicates data output from Pin 3 of the Secondary Data I/O Port
Indicates a true CTS output from Pin 5 of the Secondary Data I/O connector in RS232
Right
Mode
Left Indicates data being transmitted via the TX1 optical port
Left Indicates data being received by the RX1 optical port
Left Indicates data being transmitted via the TX2 optical port
Left Indicates data being received by the RX2 optical port.
When illuminated, indicates that the RX1 optical input port is currently selected by the
Left
Priority Select circuitry.
When illuminated, indicates that the RX2 optical input port is currently selected by the
Left
Priority Select circuitry.
