The G450 is a modular device, adaptable to support different combinations of endpoint devices.
While fixed front panel ports support the connection of external LAN switches, network data

links. IP phones are supported via an external LAN switch.
The G450 chassis features field replaceable RAM, DSPs, PSUs, fan tray, and main board
