Networking - Ip Networking - Iwatsu ENTERPRISE 5.0 Owner's Manual

Communication is supported across the IP Campus network. This means,
resources and bandwidth that would normally be dedicated to establishing
and maintaining communications in other networking configurations now
become available for use by other IP or TDM devices. Remote IP Campus
nodes have the ability to communicate without the main IP Campus node
processing the call between the two remote nodes. The main IP Campus
node receives only the Call Control Data from the two remote nodes. This
configuration allows the main IP Campus node to allocate bandwidth and
resources for processing other calls in the IP Campus network.
IP Campus also supports Omegatrek roaming throughout the network. The
Omegatrek handset will operate transparently at any remote IP Campus node
that has a base station. The Omegatrek handset extension and features are
retained throughout the network and becomes operational when in range of a
base station.
Prior to deploying voice over a WAN or VPN, a complete analysis of the
network is required to ensure sufficient bandwidth and end-to-end QoS for
voice traffic. Using a VPN or a WAN to pass SIP voice traffic allows you to
leverage both your data and telephony resources.
NETWORKING – IP NETWORKING
IP Networking provides a cost-effective IP solution for networking two or
more autonomous ECS telephone systems together, retaining all features
associated with networking via T1 and Analog E&M Tie Lines. However,
the IX-8IPNET/IX8EIPNET card leverages the ability to pass both data and
voice traffic over the same circuit. The converging of these seemingly two
different medium types (TDM and IP telephony) is possible because the IX-
8IPNET/IX8EIPNET card packetizes the voice traffic using the concise SIP
protocol.
This solution provides the ability to converge your voice and data traffic
through a Virtual Private Network (VPN) or through a managed public IP
network. Because data traffic is not real time-dependent and it rarely is in
constant use over a wide area network (WAN), SIP voice traffic often has
the resources (e.g., bandwidth) to pass easily over the same circuit. However
as later explained, prior to deploying voice over a WAN or VPN, a complete
analysis of the network is required to ensure sufficient bandwidth and end-
to-end QoS for voice traffic. Using a VPN or a WAN to pass SIP voice
traffic allows you to leverage both your data and telephony resources.
