Network
Use the Network section of the worksheet to record parameters used in
checking network connectivity between the BV1250 unit and the immediate
Ethernet switch or router to which the unit is connected.
To perform checks, a BV1250 unit transmits ICMP error checking packets
on a defined error checking timing cycle. If no reply is detected, the link
between the unit and Ethernet switch is broken and the unit will not process
calls.
This feature is typically used in cases where BV1250 units are working in
groups associated with a PBX. In this case, failed links can be bypassed as
calls are rerouted through active links.
Figure 3-20 illustrates how the various parameters (underlined) interact in
the error detection process.

the error checking packets will be transmitted during normal
operation.
