RAW mode switching

This topic contains the following RAW mode switching information:

The following illustration shows the CG 6060 switching model in RAW mode:

H.100 and local streams

The following tables list the specific use of each stream in the CG 6060 RAW switching model:

H.100 streams

H.100 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

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

timeslots 0..30

DSP voice information (T1 and E1 trunks)

Streams 64 and 65, timeslots 0.. up to 899

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 6060 boards configured as E1 depend upon the NetworkInterface.T1E1[x].SignalingType keyword setting.

The following table shows the default routing for CG 6060 boards in RAW mode:
