186 Chapter 6 • DSPs Explained
Summary
As explained in this chapter, the more complex and integrated your AVVID network
becomes, the more important your DSP provisioning decisions become,
and we feel an integral part of the planning process. Knowing ahead of time what
you expect your network capabilities to be for conferencing, transcoding, and
support will lend itself directly to the direction your DSP needs are sure to
follow.These decisions should largely be based on the size and scope of the
deployment. For smaller-sized companies, you may wish to consider a softwarebased
solution such as Cisco’s CallManager on a Windows server. Medium-sized
deployments could be handled with a Cisco Catalyst 4000 switch, while the large
enterprise would obviously best be served by a Cisco Catalyst 6000 with the
8-port T1 Voice and Service module. Clearly, whatever the size and scope of the
deployment, making a few key DSP Provisioning decisions in the planning or
early stage design of the network will save many headaches and sleepless nights as
the project grows.
