A 10 Mbps Ethernet LAN can support a fully configured, fully utilized
NBX 100 system. A 100 Mbps Ethernet LAN can support a fully
configured, fully utilized NBX SuperStack 3 system. That is, a 10 Mbps
Ethernet LAN with 200 "voice devices" (3Com telephones and outside
telephone lines) can support the toll-quality audio provided by the
NBX 100 system even when all 200 devices are in use. Similarly, a
100 Mpbs LAN can support toll-quality audio with a fully configured
SuperStack 3 NBX system. If you use an Ethernet switch, verify that it
supports the 802.1P and 802.1Q specifications.
