Are layer 2 or 3 switches used?
Use of repeater hubs can increase the network load, and therefore may result in degradation in speech quality.
To ensure high speech quality, use only layer 2 or 3 switches when connecting the IP-EXT card to the LAN.
Use of layer 2 or 3 switches is also strongly recommended for connecting IP-PTs.
Note
Note that the port of the switching hub that connects to the IP-EXT card should be set to operate under
"Auto Negotiation" mode.
Are Category 5 (CAT 5) or higher cables used?
When connecting network devices, make sure to use CAT 5 or higher cables. If other types of cables are used,
communications may not be carried out normally.
