Backplane architecture for a telecommunications system chassis
A backplane ( 11 ) of a telecommunications chassis includes a pair of controller slots that can receive respective controller modules. The backplane ( 11 ) also has a plurality of module slots that can receive respective telephony modules. Each of the pair of controller slots is connected by a plurality of buses to each of the plurality of module slots. The backplane ( 11 ) provides the ability to place any module type into any of the plurality of module slots.
1. A backplane architecture for a telecommunication system chassis, comprising:
a pair of controller slots operable to receive respective controller modules;
a plurality of module slots operable to receive respective telephony modules having different functionalities, each of the pair of controller slots being connected by a plurality of buses to each of the plurality of module slots, wherein any module is operable to be placed into any of the plurality of module slots regardless of its functionality.
2. The backplane architecture of claim 1 , wherein one of the plurality of buses is operable to indicate whether a module has been inserted into a particular one of the plurality of module slots.
3. The backplane architecture of claim 1 , wherein one of the plurality of buses is operable to provide a sparing capability in the event of a failure in a module.
4. The backplane architecture of claim 1 , wherein the pair of controller slots are connected by a controller bus operable to provide communications between controller modules.
5. The backplane architecture of claim 1 , wherein a pair of the plurality of module slots are connected by a inter-slot bus operable to provide adjacent module communications.
6. The backplane architecture of claim 1 , wherein the plurality of buses include self timed buses not requiring a clock signal.
7. The backplane architecture of claim 1 , wherein one of the plurality of buses includes individual reset lines from each controller slot to each module slot, the individual reset lines providing independent resets to any module installed in the plurality of module slots.
8. The backplane architecture of claim 1 , wherein the plurality of buses include an ethernet bus.
9. The backplane architecture of claim 1 , wherein the plurality of buses include a pair of clock distribution buses.
10. The backplane architecture of claim 1 , wherein the plurality of buses include dual H.110 buses.
