# AG 2000C switch model

This topic describes:

- The specific use of each stream, as shown for H.110 streams and local streams

- An illustration of the AG 2000C switch model

- Lucent T8100A switch blocking

## H.110 streams

H.110 streams |
--- | ---
H.110 bus | Streams clocked at 8 MHz: timeslots 0..127 for all 32 streams

## Local streams

Local stream |
--- | ---
Line interface voice in and out | Streams 0 and 1, timeslot 0..7, 0..15, or 0..23
Line interface signaling in and out | Streams 2 and 3, timeslot 0..7, 0..15, or 0..23
DSP voice in and out | Streams 4 and 5, timeslot 0..7, 0..15, or 0..23
DSP signaling in and out | Streams 6 and 7, timeslot 0..7, 0..15, or 0..23

## Switch model

The following illustration shows the AG 2000C switch model:

## Lucent T8100A switch blocking

Switching on the AG 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:

- H.110 bus to the local bus, or

- H.110 bus to H.110 bus

There are no restrictions on local switching. Any local device can be connected to any other local device.
