WAN Bottlenecks Now Readily
Your Wide Area Network or WAN may be the bottleneck in your network
when you have significant voice or data transfer between facilities.
With lower line prices available, unclogging the WAN can cost
less than you think and can unleash higher business productivity.

DS3 as an Internet Backbone
DS3 service configured as an dedicated Internet port offers 45
Mbps of upload and download bandwidth. This is ideal for small
and medium size ISPs and WISPs. that have exceeded the capacity
available from multiple T1 lines.
DS3 as Ethernet Transport
DS3 bandwidth at 45 Mbps can easily transport 10 Mbps Ethernet
over SONET or T3 line, even with the additional overhead needed
to convert from packet to TDM back to packet protocol. For Fast
Ethernet transport, an OC3 service at 155 Mbps would be required.
