Data Network Assessment for Voice Traffic

System Availability: All systems

Important! Voice over Internet Protocol (VoIP) can be affected by numerous factors related to network structure and design. To prevent delays, jitter and voice data packet loss, and achieve optimum VoIP traffic performance, your network must be designed or redesigned for voice traffic with priority over data.

Toshiba highly recommends that the installing dealer assess the existing network for proper handling of voice traffic and make sure it provides the required bandwidth per the number of deployed VoIP instruments. Toshiba is not responsible for: network assessment for voice traffic, network design/redesign or network support outside the topology it provides. Nor is Toshiba

responsible for diminished Quality of Service (QoS) caused by networks not capable of providing necessary VoIP bandwidth.

Expected voice QoS as it relates to network parameters is shown in Table 46 on page 175.

The CIX supports Toshiba proprietary IP telephones, enhancing the CIX VoIP capabilities, and providing powerful IP telephony add-on solutions for remote users. The Toshiba IPT2000- and IP5000-series telephones are compatible with all Strata CIX systems.

The Toshiba IP telephony strategy is based upon a transitional approach. For most enterprises, the migration path to IP telephony will be a gradual process rather than an event in time. Instead of acquiring IP technology benefits through complete system replacement at higher cost and higher risk, most enterprises prefer to integrate voice and data IP traffic into their existing telephone

systems as the need arises. This protects their investment in existing voice and data networks and represents a low risk migration path. Toshiba has transformed Strata CIX systems into IP-enabled communication systems to achieve this very important objective.
