Based on information discovered during the investigation phase of the design, it has been decided that the proper deployment model for Ajaxis single-site call processing. The access layer devices will be placed in the IDF closets, the distribution layer devices will be placed in the MDF closets, and the core will be deployed in the computer room.
In the three office buildings, each floor has an IDF, which services approximately 70 to 80 users. Each of the R&D and Manufacturing buildings also has an IDF. Building 1 also houses the MDF in the basement. Ajax is currently using Toke Ring and an FDDI backbone. The network is to be migrated to a 100BaseT or faster Ethernet network.
Ajax has had many network outages in their current network and is concerned with network availability, especially because the phone system will now be residing on the same network.
