SCVi's Internet and Phone Service Wiring

This posting explains the physical infrastructure that provides Internet and Phone service to SCVi. It was written to help Staff, Parents, and Voluteers understand SCVi's hard wiring for future troubleshooting or upgrades.

SCVi currently has two internet providers, Telepacific and Fireline Broadband.  Each has different physical infrastructure.

Fireline

Fireline connects to the school through a microwave dish on the roof.  We currently have 10 Megabits of internet service through this connection.

This is powered through a P.O.E injector in the data center.  The P.O.E. injector sends power up to the transceiver that is mounted on the back of the microwave dish to power it.  It is connected with an ethernet connection so that network traffic can be provided to our gateway router.

Overall, they have been a reliable provider.  There have been three times when this connection has gone down.

1. A fire on Mt. Wilson interrupted service. - Fireline let us know and restored things when the fire had cleared.
2. The P.O.E. injector failed.  Fireline's technicians promptly came and replaced it.
3. Config problems at central office. Fireline immediately resolved the issue after we called them and notified them. 

Telepacific

Telepacific connects to the school through the outdoor electrical room. This is the room in back of the school that says "Electrical Room F.A.C.P. Inside" on the door. We currently have 10.5 Megabits of internet service through this connection.

There are 8 different connections that come in to the school. They each have a small control interface locked inside a box.  There are two separate boxes for the 8 interfaces. One box has the voice connection and one data connection. The other box has 6 data connections.

These then travel through a large cable to the communications panel inside the Roof Access electrical room upstairs near the main stairwell.   Note, there are also two POTS lines that run from the outdoor electrical room to specific places in the building. One is being used for the elevator, the other is currently unused.

The 7 data connections are bound together in the data center.  This provides a single output that can then be connected to our gateway router.

The phone line goes to the call manager.

This table summarizes the circuits.

Connection Type	Circuit Number	Purpose
PRI (Phones)	13-HCGS-732952-PT	Provides phone connection for VOIP Phone system
Data 1	13-HCGS-746439-PT	Bonded to form 10.5 Megabit Data connection
Data 2	13-HCGS-792043-PT	"
Data 3	13-HCGS-792044-PT	"
Data 4	13-HCGS-792045-PT	"
Data 5	13-HCGS-792046-PT	"
Data 6	13-HCGS-792047-PT	"
Data 7	13-HCGS-792048-PT	"

Overall, Fireline has also been a  reliable provider.  The only time we lost service was due to a wire being unplugged in the outdoor electrical room.
