Configuring The Ata 2 - Nortel BCM50 Installation And Maintenance Manual

2 Ensure that the analog port terminates correctly in 600 ohms:
• Replace the analog telephone with the test set
• Use RECEIVE/600 OHM/HOLD mode on the test set
3 Ensure that the test set connects in parallel to the service line before removing the analog
telephone or the line drops.
4 Remove the single-line telephone.
5 Measure the 1 kHz tone at the far end of the analog port, which is where the analog loop ends
and where the analog device connects.)
Note: The tone must be greater than - 10 dB (for example: - 9 dB is acceptable).
For analog device to CO measurement
Use this procedure to measure the insertion loss from the analog device to the CO.
1 Establish a connection to a silent termination on the CO service line with an analog telephone
attached to the ATA 2.
2 Make sure the analog port terminates correctly in 600 ohms by:
• Replace the analog telephone with the test set
• Use TRANSMIT/600 OHM/HOLD mode on the test set
3 Make sure the test set connects in parallel to the service line before removing the analog
telephone or the line drops.
4 Remove the analog telephone.
5 Introduce a 1 kHz tone into the analog line at - 10 dBm, and measure the level at the CO
exchange.
Note: The difference in levels is the transmit loss and must be less than 10 dB
(for example, 9 dB is acceptable).

Configuring the ATA 2

Configure the ATA 2 using the BCM50 Element Manager. For detailed configuration information
