Crosspoint’s network planning and design services allows for modelling and simulation of complex networks ranging from in office solutions to multinational solutions. When network planning, Crosspoint’s Engineering team focuses on visualizing network routing and performance behaviour; project “what-if” scenarios, design and troubleshooting; optimize network capacity and growth; and architect network resiliency and survivability. 

Crosspoint carefully plans the network infrastructure for smart and optimum routing, and visually represents these plans with traffic-flow diagrams. These diagrams allow for routing dynamics, end-to-end connectivity, and security gaps to be seen with a glance.

Crosspoint can also foresee which network areas would be most affected by outages and where resulting bottlenecks are likely to occur, allowing us to pre-empt these issues and deploy solutions providing optimum performance for the voice over IP (VoIP) or video over IP traffic.

During the VoIP capacity planning process Crosspoint considers the following:

• Your local area network (LAN) and/or wide area network (WAN)

• Existing data traffic on the network

• The voice codecs your VoIP solution will use

• Connectivity to the Public Switched Telephone Network (PSTN)

• Your network's hardware infrastructure
• VoIP and network redundancy

During your VoIP capacity planning, Crosspoint will assist in determining if remote locations will continue to have PSTN connectivity or if that connectivity will be consolidated at a central location. All phone calls would pass through WAN links to a central location where the calls would proceed out the associated PSTN gateway. Centralising PSTN connectivity can simplify VoIP network planning and consolidating hardware can decrease costs and increase redundancy.

PSTN consolidation can also impact VoIP network capacity. For example, if your remote locations incur long distance charges to call each other or a home office, it might be better to pass internal voice traffic through your WAN but pass local, outside calls through a local PSTN gateway. Crosspoint can easily accomplish this by routing calls based on destination area code and prefixes.
