CDR Received Indicator
The red LED labeled “CDR RECEIVED” should be lit momentarily each time a Call Detail Record is received by the IAM.
Alarm Indicator
The red LED labeled “ALARM” should be lit whenever a fault (such as the call record buffer is full or the data bus has failed) is detected.
Low-Battery Indicator
The red LED labeled
Printer Indicator
The red LED labeled “PRINTER” should not be lit when DIP switch section #5 (for the output to the printer) is off (down position).
The red LED labeled “PRINTER” should be lit when DIP switch section #5 (for the output to the printer) is on (up position). It should go off and on with the receipt of XOFF and XON signals respectively from a connected printer. It should flicker at a fast rate if no printer is connected.
Power Indicator
Whenever power is applied, the green LED, labeled “POWER”, should be lit (there is no off/on switch).
Front Panel Connector
The connector on the front panel of the IAM is reserved for future use.
Printer
The printer can be used for a hard copy backup of the raw Call Detail Records. The data to the printer can be turned on and off with DIP switch section 5. Up is on and down is off. Do not reset the IAM for this section of the DIP switch.
Resets
Soft Reset
A soft reset is accomplished by pushing the RESET button on the front panel for about 2 seconds, or until all the front panel LED indicators that were off, flash on simultaneously and then back off.
Clearing RAM
There may be occasions when the RAM needs to be cleared (such as after replacing a RAM chip). The RAM is cleared by using the Clear Call Detail Buffers operation in the GTI Configurator software, or by using the hardware- based procedure described here.
CAUTION
Retrieve all call detail records that you want to keep, using the Retrieve Call Detail Data operation in the GTI Configurator software, before clearing the RAM. When the RAM is cleared, all call detail records stored in RAM will be lost.
To clear the RAM using the RESET button on the front of the IAM, use the following procedure:
1.Write down the present positions of the DIP switches located on the back panel.
2.Set DIP switch 1 to the up (test) position and DIP switches 2 through 8 to the down position.
3.Push the RESET button on the front panel for about 2 seconds, or until all the front panel LED indicators that were off, flash on simultaneously and then back off.
4.Set DIP switch 1 to the down (operate) position and DIP switches 2 through 8 to the positions noted in the first step.
5.Push the RESET button on the front panel for about 2 seconds, or until all the front panel LED indicators that were off, flash on simultaneously and then back off.
To verify that the RAM has been cleared, use the Status info operation in the GTI Configurator software to look at the number of records for each telco line. For more information, see the GTI Configurator software user’s guide.
