Cisco 3600 Series: Solutions for Branch Offices
Explore the incredible flexibility of Cisco 3600 series
solutions with these examples for the multiservice branch
office environment, whether you need dial access, routing or
LAN-to-LAN services, or multiservice networking. No
matter how much your requirements may vary from place to
place, the Cisco 3600 platform has the performance and
diversity to meet your needs, at a very cost-effective price.
Multiservice Access Server and Router
For branch offices that depend upon a variety of network
services, you can consolidate these services into a solution
built upon the Cisco 3600 platform. While many people are
thinkingofmultiservicebranchofficenetworksthatintegrate
voice and video with data over the same infrastructure, a
Cisco 3600 solution takes this flexibility one step further by
adding dial access, routing, and LAN-to-LAN services.
Platform modularity comes into play as multiservice
networks perform a variety of tasks. Listed in Table 2 are
some possible requirements along with options available to
meet those needs.
This integrated, all-in-one solution to multiple
requirements is extremely cost effective to install and
manage. It costs more to purchase multiple devices, and you
would sacrifice the flexibility of a Cisco 3600 solution when
your requirements change. Remote manageability also saves
you money by lowering deployment and management costs.
Another cost advantage is consolidation of WAN services
into fewer lines. To protect your investment when you must
change connectivity or services, just swap a network module
at minimal additional cost or service disruption.
As a multiservice solution, you can rely upon the
outstanding performance, reliability, security, and flexibility
of the Cisco 3600 platform to meet your needs for many
years. Cisco IOS software contains many features that
provide security, reliability, and WAN optimization.
