Creation of a video environment for the organization is required. This should be convergent network which can be fixed without incurring a lot of cost on installations or changing the existing network architecture. The number of channels also needs to be increased. One circuit should be enhanced with IP based technology to have a maximum number of channels where communication can take place.

Reducing the cost of running the company by ensuring that video conferencing can be set up in at least main branches of Rapid Freight will subjugate traveling allowances for meetings or wasting of time. The technologies for this should be efficient and cheaper. Provide for technologies which give room for scalability as Rapid Freight is growing increasingly. This should cover for future expansion utilizing bandwidth by converging different technologies. LAN can be used within a branch and an ISDN between organizations. This includes approaching an IP/VoIP provider.

[...] This will accommodate the increasing number of Rapid Freight employees. The PBX is configured to terminate to an IP/VoIP provider. IP software has to be installed usually from vendors like CISCO. If Cisco is used to implement the IP over ISDN, in response of bandwidth demand ISDN allows for the B channels to be drooped or added. When also performing voice over ISDN, reordering of packets needs to be managed by Multi Class Multilink PPP (MCMP). It gives interleaving packets a header number with a sequence number. [...]


[...] This ensures scalability in when company expands. Secondly, IP networks fee payment is not ?metered? as in ISDN, but the fee is paid monthly and sometimes it is fixed. This will relieve the cost incurred by the organization because the users will be using the service as much as they can, but the fee is fixed (Cisco Systems, Inc., 2006). It has direct saving in infrastructure cost since the line from the telecom provider can be shared among the users (PBX trunk). [...]


[...] IP network will serve as a backbone for all Rapid Freight communication needs cost-effectively. VoIP is the latest main step in the process (convergence), and it is the specific convergence proposed for Rapid Freight because of its requirements. Rapid Freight needs gateways and converters to connect its landline to the VoIP world. It allows users to receive and make VoIP calls. VoIP uses IP packets maintaining quality and reliability. Devices in communicate by identifying each other with IP addresses unique number). [...]
