## RAW mode switch model

The following illustration shows the CG 6565C switching model in RAW mode:

## H.110 and local streams

The following tables list the specific use of each stream in the CG 6565C RAW switching model:

### H.110 streams

H.110 bus | Streams 0..31, timeslots 0..127 (Streams clocked at 8 MHz)

### Local streams

Trunk voice information (T1 trunks) | Trunk 1: Streams 0 and 1 Trunk 2: Streams 4 and 5 Trunk 3: Streams 8 and 9 Trunk 4: Streams 12 and 13 Trunk 5: Streams 16 and 17 Trunk 6: Streams 20 and 21 Trunk 7: Streams 24 and 25 Trunk 8: Streams 28 and 29 Trunk 9: Streams 32 and 33 Trunk 10: Streams 36 and 37 Trunk 11: Streams 40 and 41 Trunk 12: Streams 44 and 45 Trunk 13: Streams 48 and 49 Trunk 14: Streams 52 and 53 Trunk 15: Streams 56 and 57 Trunk 16: Streams 60 and 61 | timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23 timeslots 0..23
Trunk voice information (E1 trunks) | Trunk 1: Streams 0 and 1 Trunk 2: Streams 4 and 5 Trunk 3: Streams 8 and 9 Trunk 4: Streams 12 and 13 Trunk 5: Streams 16 and 17 Trunk 6: Streams 20 and 21 Trunk 7: Streams 24 and 25 Trunk 8: Streams 28 and 29 Trunk 9: Streams 32 and 33 Trunk 10: Streams 36 and 37 Trunk 11: Streams 40 and 41 Trunk 12: Streams 44 and 45 Trunk 13: Streams 48 and 49 Trunk 14: Streams 52 and 53 Trunk 15: Streams 56 and 57 Trunk 16: Streams 60 and 61 | timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0...30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30 timeslots 0..30
DSP voice information (T1 and E1 trunks) | Streams 64 and 65, timeslots 0.. up to 1500

## Voice information routing on T1 trunks (RAW mode)

If NetworkInterface.T1E1[x].SignalingType is set to RAW, information is routed to accommodate a configuration where no signaling is present on the T1 trunk. Voice information is transmitted in all 24 channels.

Each voice channel on the T1 trunk is placed in a corresponding timeslot on the local bus in the following streams:

## Voice information routing on E1 trunks (RAW mode)

If NetworkInterface.T1E1[x].SignalingType is set to RAW, voice information is transmitted in 31 channels. Timeslot 0 on the E1 line carries framing data.

The following illustration shows how voice channel data is assigned to timeslots:

## T1/E1 signaling information routing (RAW mode)

No signaling information is transmitted in RAW mode. It is assumed that another E1 trunk is carrying a D channel containing signaling for all trunks. In this mode, the local trunk signaling streams have zero timeslots.

## Default connections (RAW mode)

If a board is configured for standalone operation (that is, Clocking.HBus.ClockMode = STANDALONE), the DSPs and trunks are connected as shown in the following table.

Note: The SwitchConnections keyword can override this setting.

The exact settings for CG 6565C boards configured as E1 depend upon the NetworkInterface.T1E1[x].SignalingType keyword setting.

The following table shows the default routing for CG 6565C boards in RAW mode:
