Voice Ready Network
3Com Voice Ready Networks provide an innovative and
holistic approach to assessing, recommending and
implementing a converged network, solving the most
vexing challenges that confront IT managers as they
deploy Internet Protocol (IP) telephony systems. With
3Com Voice Ready Networks, organizations can
optimize network infrastructure for realtime voice and
video traffic, ensure secure communications and
protect business assets.
The Baseline Plus Switch 2250 is an integral
component of this approach, offering:
› Automatic assignment of voice traffic to separate
VLANs
› IEEE 802.1p prioritization and 802.1q VLANS
› IEEE 802.1x authentication
› Two dual-personality Gigabit SFP ports
› SNMP support
