LOCAL AREA NETWORK & WIRING SCHEME
Two Local Area Network (LAN) segments will be implemented in each school and the District Office. The transport speeds will be Ethernet 10BASE-T, 100BASE-TX, and 100BASE-FX. Horizontal cabling shall be Category 5 Unshielded Twisted Pair (CAT5 UTP) and will have the capacity (be tested) to accommodate 100 Mbps. Vertical (Backbone) cabling shall be CAT5 UTP or fiber optic multi-mode cable. The cabling infrastructure shall comply with TIA/EIA-568-A and TIA/EIA-569 standards.
One LAN will be designated for student / curriculum usage and the other will be designated for administration usage (see: SECURITY SECTION). The LAN infrastructure will be based on Ethernet LAN switching. This will allow for a migration to faster speeds (more bandwidth) to the individual computers and between MDFs and IDFs without revamping the physical wiring scheme to accommodate future applications.
In each location a Main Distribution Facility (MDF) room will be established as the central point to which all LAN cabling will be terminated and will also be the point of presence (POP) for the Wide Area Network connection. All major electronic components for the network, such as the routers and LAN switches, will be housed in this location. In some cases an Intermediate Distribution Facility (IDF) room will be established, where horizontal cabling lengths exceed TIA/EIA-568-A recommended distances or where site conditions dictate. In such cases, the IDF will service its geographical area and the IDF will be connected directly to the MDF in a STAR or EXTENDED STAR topology.
Each room requiring connection to network will be able to support 24 workstations and be supplied with four (4) CAT 5 UTP runs for data, with one run terminated at the teacher's workstation. These cable runs will be terminated in the closest MDF or IDF. All CAT 5 UTP cable runs will be tested end-to-end for 100 Mbps bandwidth capacity. A single location in each room will be designated as the wiring point of presence (POP) for that room. It will consist of a lockable cabinet containing all cable terminations and electronic components; i.e. data hubs and switches. From this location data services will be distributed within the room via decorative wire molding. Network 1 will be allocated for general curriculum usage and network 2 will allocated for administrative usage..
