2.4.1

 

Design Considerations for Campuses 

There are many factors to consider when choosing Customer Premise Equipment (CPE).  An 
entire document, 

New Site Requirements

, is devoted to the subject and provides much greater 

detail.  Here are just some of the decisions to consider: 

 

What is the number of users at the site? 

 

What is the amount of bandwidth available to reach the site? 

 

What is the concurrent call capacity? 

 

What are the future growth requirements? 

 

Is a compressed CODEC (e.g. G.729) required? 

 

Will video conferencing be used? 

 

How many simultaneous video calls to be expected?  

 

What are the call patterns of the users? 

 

Does the campus equipment need to be redundant? 

 

Does the campus need to be survivable such that station-to-station calls continue to 
function? 

 

Does the campus need to be survivable in reaching the PSTN 

– being able to dial 

emergency services if the core call control is not reachable? 

 

Does the campus equipment need to support a fail-over or backup network? 

 

How will remote and teleworker users connect to the service? 

 

How will SIP phones obtain their configuration information? 

 

Can the correct ports be opened on the firewalls? 

Answering these questions will help Aastra and its partners design and deploy the optimum 
Clearspan solution components for campus locations. 

2.4.2

 

Clearspan Server Interworking 

Up to this point we have introduced the servers and peripheral elements required to implement a 
Clearspan solution, and also reviewed the high-

level “Campus” deployment architecture. This 

section examines how these servers interact, and what role they play during the typical call setup 
situations. The cases for outbound, inbound, and internal calls are addressed. In the examples 
seen on the following pages, while SIP endpoints are being used, other endpoints (Analog, Digital, 
etc.) may also be used as part of the solution, provided that any additional equipment required to 
interface to the IP network is also added.
