Scenarios for Deploying Clear Channel T3 and E3 WAN Configuration
30.19.2 Scenario 2: Routed Metropolitan Backbone
In this scenario, a number of service providers are connected by a Metropolitan Backbone. The backbone consists of
RS 8000s connected by Clear Channel T3 (CCT3) links.
An MSP provides a Channelized T3 (CT3) service using an RS 8000. A company has two sites that connect to this
service:
• The head office (hqsite) connects using a Channelized T3 line from an RS 8000.
• The remote site, rsite, connects to the RS 8000 at head office using four Channelized T1 lines
bundled with Multilink PPP, a fractional T1 line, which provides one 768 Kbps service, one 384
Kbps service, and six 64 Kbps services. Also, a full (unstructured) T1 link is connected directly to
the RS 8000.
Internet Service Provider A uses a Clear Channel T3 link to the Internet. Internet Service Provider B provides a
Channelized T3 service to an Application Service Provider and a Content Provider, both of which connect using
Channelized T3 lines from an RS 8000.
Figure 30-14 shows the network layout for this scenario. The tables following the figure show the commands used to
configure the interfaces for the routers at the various locations.
