This topic contains the following RAW mode switching information:
The following illustration shows the CG 6565C switching model in RAW mode:
The following tables list the specific use of each stream in the CG 6565C RAW switching model:
H.110 bus |
Streams 0..31, timeslots 0..127 (Streams clocked at 8 MHz) |
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 |

Trunk voice information (E1 trunks) |

DSP voice information (T1 and E1 trunks) |
Streams 64 and 65, timeslots 0.. up to 1500 |
|
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:
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:
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.
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:
