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:

• replacing the analog telephone with the test set

•using

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.

Configuring the ATA 2

Configure the ATA 2 using the Business Communications Manager Unified Manager. For detailed

configuration information refer to the Programming Operations Guide, Appendix D.

Note: The difference in levels is the transmit loss and must be less than 10 dB

(for example, 9 dB is acceptable).
