Power Meter
In addition to full WAN analysis, The Advisor E1/T1 (D models), and E3/DS-3
interfaces have a built-in pulse amplitude power meter that allows you to check
power levels with a resolution of +/- 1 dBm. The dynamic range is between +6
dBm and –40 dBm.
Bit Error Rate Testing (BERT)
Many times problems on the network can be attributed to the transmission
medium. The Advisor has a powerful, built-in bit error rate test capability.
For a complete description of this functionality, please refer to the ATM-WAN
Technical Specification document 5980-0786E.
