This topic describes:
The specific use of each stream, as shown for H.110 streams and local streams
An illustration of the CX 2000C switch model

The following illustration shows the CX 2000C switch model:
Switching on the CX 2000C 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.110 connections is limited to a maximum of 128 full duplex or 256 simplex (or half duplex) connections, in any combination, from either the:
H.110 bus to the local bus
H.110 bus to H.110 bus
