5.3 Running Diagnostics

When you set up a new connection, you can verify the link connectivity using PING prior to
sending data. A Latency and Jitter Test will verify the quality of the link.

5.3.1 PING Testing

You can verify network connectivity with another IP device within the subnet by sending a PING
to the IP address for that device. For PING testing instructions, see the 9145E NID Software
User Manual.

5.3.2 Latency and Jitter Testing

Latency/Jitter Testing measures and reports performance and quality of the link between the
9145E and another Canoga Perkins device. Results reported include the Frame Loss Ratio
(FLR), and the minimums, average, and maximums for latency and jitter. For latency and jitter
testing instructions, see the 9145E Ethernet NID Software User Manual.

5.4 Loopback Diagnostics

Use Loopbacks to diagnose a fault on the optical link. The 9145E supports two loopback modes
that you can set at the local site for both the local and remote 9145Es. These modes loop the
data through either the physical layer on the User side or the Network side.
When performing loopback diagnostics, the 9145E uses a unique MAC address, designated as
the Loop Test MAC Address, which is displayed on the Loopback Setup Screen (see the 9145E
