Pinging the Processor
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-10 represents a typical BTS Ethernet
configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that routes request packets to the LAN network
modules to obtain a response from the specified “targeted” BTS.
