The media selected for the network is inexpensive Category 3 UTP jumper cabling. The low cost, durability, and ready availability of UTP makes it by far the preferred media for this installation. If there were specific electrical noise or distance considerations, the Network Designer may have decided to attempt a design using multimode fiber optic cabling or other media. This media selection removes the SEH-22FL, a fiber optic device, from the selection field.

As this is a small home office that does not plan to grow substantially, the ability to expand the network is not a primary concern. As there is no apparent need or desire to quickly and easily expand the network, the stackable products in the selection field are not required. Again, if later criteria prove that the remaining devices in the selection field do not measure up to the network’s needs, these can be reintroduced to the selection field.

The easiest decision in the process of home office network design is the comparison of required port count (the number of stations that will be part of the network) and the port count supplied by the devices in the selection field. In the case of this example, the comparison indicates that the one remaining device in the selection field, the MR9T-E, provides three more 10BASE-T networking station ports than the network requires. The MR9T-E, therefore, meets all of the criteria judged to be important for this network.
