The following illustration shows the CX 2000 switch model:
CX 2000 switch model
Switching on the CX 2000 board is implemented by the Lucent T8100A chip (HMIC). The Lucent T8100A chip can perform local bus to local bus switching in full non-blocking fashion.
The number of H.100 connections is limited to a maximum of 128 full duplex or 256 simplex (or half duplex) connections, in any combination, from either the:
H.100 bus to the local bus
H.100 bus to H.100 bus
