## (5) WAN Media

### Media Costings

NOTE: Only cable in the wiring closets (patch cables etc) are priced here.
NOTE: The major expense in the WAN setup will be the runs of T1s between schools & regional Hubs; however these cannot be priced because distances were not provided.

Service Center | T1 | 19 | 3m | $52.50 | $997.50
Shaw Butt School | T1 | 19 | 3m | $52.50 | $997.50
Shaw Butt School | ISDN | 1 | 2m |  |
Data Center | T1 | 19 | 3m | $52.50 | $997.50

### Types of Media Interconnection

From | To | Type Of Connection | Qty | Line Speed | WAN Protocol | Purpose
District Center to ISP
Data Center | ISP | {unkown}... although 6 x T1s (or 2x T3s) would suffice | {unkown} | 1.54 Mbps (per T1) | Frame Relay | provides fast (Frame Relay) Internet connectivity.
Core Router to Core Router
Service Center | Shaw Butt School | T1 | 4 | 1.54 Mbps (per T1) | PPP (Point to Point Protocol) | provides schools with access to the web, and any other services available on the Data Centers public network.
Service Center | Data Center | T1 | 4
Shaw Butt School | Data Center | T1 | 4
Core Router to Site Based Router media
Service Center | Schools | T1 | 11 | 1.54 Mbps (per T1) | (Point to Point Protocol) | provides schools with access to Core network
Shaw Butt School | Schools | T1 | 11
Data Center | Schools | T1 | 11
Service Center | Schools | phone line | 11 | 144 Kbps (each line) | ISDN BRI | each school (including the community school) has an emergency dial-in ISDN number to use whenever there is a problem with the schools network connection.
Shaw Butt School | Schools | phone line | 11
Data Center | Schools | phone line | 11
Service Center Router to Community School
Service Center | Community School | existing phone line | 1 | 144 Kbps | ISDN BRI | this small school requires a permanent dial-in ISDN, allowing dial-in Internet access to a very small number of users

Note: Ideally (depeding on budget) the following reduncancy of media should be provided:

- Between each regional Hub an extra 4 unused T1 lines are run alongside the 4 existing T1s (all the way to the patch panels).
  - Not only this useful if a line fails, but it is likely network administrators might decide load sharing between just 4 T1s on this Core Network is not sufficient - especially if additional schools join the network and these connection become a bottleneck.
