This section describes the options available for businesses that are able to utilize data networks to support
voice solutions such as Voice over IP (VoIP). IP Office offers networked voice and data communications,
providing:

· Built-in IP router

· One link for voice and data networking

· Common access to the Internet; share files and send e-mails to other sites

· Support for RIP-2 protocol for dynamic data routing; IPSec VPN, firewall and NAT (Network Address

Translation) and for security; Centralized management and proactive fault management via SNMP.

 

IP Packet based voice networking between IP Office sites can be achieved in a number of ways:

· VoIP over an unstructured private circuit.

· VoIP over a managed IP VPN.

· VoIP over a managed Frame Relay network.

· VoIP across the campus LAN.

· VoIP across the public network.

Data networks can be constructed with IP Office using unstructured point-to-point data circuits (X.21, V.35) at
speeds of up to 2 Mbps. These data circuits are accessed via optional Wide Area Expansion modules (one port
is included on IP400 system units) and Voice Compression Modules (VCM). This approach can realize
significant savings by allowing packetized VoIP calls to be interleaved with data on up to 7 leased data circuits
with spare bandwidth. Depending on required solution sizing, IP Office supports from 3 to 128 concurrent VoIP
calls. This option is not supported on IP500 systems.
