h1. Integrated Site Controller (CLN1480A)

This is a unit that interfaces up to 8 Base Radios with the core network of the Dimetra TETRA network (SwMI).

Hardware-wise, it is a [[PowerPC]] based system, looking very much like an old-fashioned PC mainboard with both ISA and PCI slots.

The mainboard houses the [[PowerPC]] CPU and it has slots for RAM.

There are some extension cards plugged into the system:

* Clock generation card (ISA, full length).

** has an integrated GPS receiver, to which you attach a GPS antenna

** generates the reference 5MHz clock distributed over Coaxial cable to the Base Radios 

* Ethernet Card using DEC tulip chipset (PCI)

** This card is what talks to the Base Radios (BR) via 10-Base-2 

* Unknown card with RJ-45 jack (REDUND) on the back. Might be E1 

There are further inputs and outputs on the system:

**** A DB-15 jack for X.21 synchronous serial backhaul (2048Mbps)

**** FIXME

**** A RS-232 serial port for local configuration
