Replace the system’s LAN cable.

The far site is not available.

Use the ViewStation web interface to 
run the Ping test (Set Up System> 
Diagnostics > Ping) to determine 
whether the far site is accessible to 
your system. If the test fails, the far site 
system is unavailable.

The system is not configured 
correctly for the network.

Check your IP configuration. For 
detailed instructions, see

A system using a 
V.35/RS-449/RS-530 
interface cannot 
receive calls at 
certain speeds

All

V.35/RS-449/RS-530 systems 
cannot determine how to 
allocate bandwidth for call 
speeds that are divisible by 
both 56 and 64 (such as 448K: 
8 x 56K), so the call cannot be 
connected correctly.

Call the far site, or have the caller try 
again at a different call speed.

Cannot select 112 or 
128 speeds for 
bonding calls from 
the speed selection.

All

These speeds do not show 
when you select the speed 
icon.

Add line speeds on the Admin 
Settings > Video Network > Dialing 
Speeds screen.

Cannot complete 
calls to sites that do 
not use encryption

All

The system displays a 
message stating that 
encryption is required.

Your system is configured to require all 
calls to be encrypted, and encryption is 
not available at the far site.
