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
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 IPT2010-SD and
IPT2020-SD 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.

IP Interface Unit

System Availability: All systems
The MIPU / LIPU and GIPH IP interface card works in conjunction with the system processor to
provide distributed IP processing capabilities that include peer-to-peer IP telephone
communication and IP Strata Net multi-system networking. MIPU / LIPU and GIPH cards install
in card slots in Strata CIX base or expansion cabinets.
The MIPU comes in two flavors: MIPU16 and MIPU24. The MIPU supports up to 24 channels
even when the echo tail length canceller is set up to 64ms. The GIPH installs into the Strata CIX40
system. The GIPH card on the CIX40 supports up to 8 IP channels. The LIPU card can support up
to 16 IP channels on all CIX systems. With the LIPS sub-card on board it can support up to 32
channels. Each IP card type has a Network Interface Card (NIC).
When programmed for G.711 codec, or G.729A with 16 ms echo cancel delay the MIPU, LIPU or
LIPS supports 16 IP channels and GIPH supports 8 IP channels. When programmed for G.729A
codec and 32 ms echo cancel delay the LIPU or LIPS provides 12 of the 16 channels; on GIPH 6
of 8 channels are available. Refer to the Strata CIX Programming manual for more details.
