5.1 Introduction

This chapter:

• Describes the CG 6100C switch model.

• Describes how trunk channels interface with H.110 timeslots on CG 6100C boards.

• Describes how trunk channels are automatically routed to DSP resources if CT bus switching is not enabled.

• Explains how you can change this default routing by enabling switching.

5.1.1 Switch Blocking

The number of H.110 connections are limited to a maximum of 512 full duplex or 1024 simplex (or half duplex) connections, in any combination, from either:

• H.110 bus to the local bus

• H.110 bus to H.110 bus
  Note: The CG 6100C board does not support switching signaling from trunk-to-trunk or from trunk-to-bus. Signalling must terminate on the board.

The following diagram shows a fully populated CG 6100C board with a daughterboard. The numbers in the diagram represent the quantity of timeslots available on each (simplex) interconnection.

Figure 27. CG 6100C Board With Daughterboard

To use the CG 6100C board effectively, it is helpful to understand its TDM switching capabilities and limitations. To ensure that there are sufficient switching resources available, the board must be configured appropriately.

In a 16 trunk configuration, the board is a mirror image, with eight trunks connected to each of the two baseboard T8105 TDM switches. Each TDM switch is also connected to a number of DSPs. To conserve timeslots on the streams connecting the two switches, trunks should be connected to the DSP resources on the nearest switch whenever possible.

When all DSP resources are treated as a single pool, resources are allocated effectively at random from the entire pool. For example, if Trunk 10 (connected to the second TDM switch) is connected to a DSP wired to the first TDM switch, the two TDM switches would have to be connected. In a worst-case scenario, the board will run out of timeslots on the inter-switch streams, and connections will fail with a NO_PATH error.

To avoid this situation, use multiple resource pools that divide the DSP resources into two groups, one per TDM switch. For more information on multiple resource pools see Setting Up Resource Management for Multiple Pools.

Connections that traverse multiple TDM switches incur a higher frame delay penalty. This can be avoided by properly configuring the board.

The eight trunk configuration does not require special configuration because of the smaller number of trunk timeslots. Even in the worst case scenario, inter-switch timeslot resources will not be exhausted.

5.2 CG 6100C Switch Models

This chapter describes the three switch models supported by the CG 6100C board. They are:

• Channel Associated Signaling (CAS)

• Primary Rate Interface (PRI)

• RAW

To define your switch model for CG 6100C boards configured for T1/E1, use NetworkInterface.T1E1[x].SignalingType.

5.2.1 CG 6100C Switch Model: CAS Mode

The following diagram shows the CG 6100C switching model in the CAS mode:

Voice and Signaling Information Routing on T1 Trunks
(CAS Mode)

If NetworkInterface.T1E1[x].SignalingType = CAS (its default setting), voice and signaling information is routed to accommodate a T1 channel associated signaling configuration. Voice information is transmitted in each channel on the T1 trunk and each channel is placed in a corresponding timeslot on the local bus.

Signaling information is transmitted in each channel using robbed-bit signaling. The signaling information is broken out and placed on the corresponding signaling stream for that trunk. The signaling information for a given channel is placed in the same timeslot number as the voice information for that channel.

Note: The CG 6100C board does not allow signaling streams to be connected to the CT bus.

Figure 29 shows how data is assigned to timeslots on a T1 trunk.

Figure 29. Connecting T1 Timeslots (CAS Mode)

Voice and Signaling Information Routing on E1 Trunks
(CAS Mode)

Regardless of the NetworkInterface.T1E1[x].SignalingType setting, the CG 6100C board routes the voice information by assigning E1 timeslots 1 through 15 to the local bus timeslots 0..14. E1 timeslots 17 through 31 are assigned to the local bus timeslots 15..29. Timeslot 0 on the E1 line carries framing data.

Figure 30 shows how voice channel data is assigned to timeslots:

Figure 30. Connecting E1 B Channels to Timeslots (CAS mode)

If NetworkInterface.T1E1[x].SignalingType = CAS (the default setting), signaling information is routed to accommodate channel associated signaling. Line channel 16 carries the signaling information for all channels.

Signaling information is broken out and placed on the corresponding signaling stream for that trunk. The signaling information for a given channel is placed in the same timeslot number as the voice information for that channel.

Note: The CG 6100C board does not allow signaling streams to be connected to the CT bus.

Figure 31 shows how signaling data is distributed (although the streams are shown here, they cannot be switched to the CT bus):

Default Connections (CAS Mode)

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

Note: The board keyword SwitchConnections can override this setting.

The exact settings for CG 6100C boards configured as T1 or E1 depend upon the setting of the NetworkInterface.T1E1[x].SignalingType keyword.

The following table shows the default routing for CG 6100C boards in CAS mode.

5.2.2 CG 6100C Switch Model: PRI Mode

The following diagram shows the CG 6100C switching model in the PRI mode:

Figure 32. CG 6100C Switch Model: PRI Mode

The following tables list the specific use of each stream in the CG 6100C PRI switch model:

DSP Voice Information (T1 and E1 Trunks)	Streams 64 and 65, timeslots 0...495 (maximum)

In PRI mode, the D channel signaling is automatically terminated by an internal HDLC controller.

Voice Information Routing on T1 Trunks (PRI Mode)

If NetworkInterface.T1E1[x].SignalingType = PRI, signaling information is routed to accommodate the T1 ISDN common channel signaling configuration where voice information is transmitted in the first 23 channels. Each voice channel on the T1 trunk is placed in a corresponding timeslot on the local bus in the following streams:

Figure 33. Connecting Voice Channels To Timeslots (PRI Mode)

Voice Information Routing on E1 Trunks (PRI Mode)

Regardless of the NetworkInterface.T1E1[x].SignalingType setting, the CG 6100C board routes the voice information by assigning E1 timeslots 1 through 15 to the local bus timeslots 0..14. E1 timeslots 17 through 31 are assigned to the local bus timeslots 15..29. Timeslot 0 on the E1 line carries framing data.

Figure 34 shows how voice channel data is assigned to timeslots:

Figure 34. Connecting E1 B Channels to Timeslots (PRI mode)

T1/E1 Signaling Information Routing (PRI Mode)

If NetworkInterface.T1E1[x].SignalingType = PRI, signaling information is routed differently to accommodate an ISDN common channel signaling configuration, where CCS signaling packets are transmitted in the D channel.

In PRI mode, the trunk signaling streams are not used. In this case, each trunk signaling stream has zero timeslots.

On CG 6100C boards framer signaling is hard wired to internal HDLCs when the board runs in PRI mode. Refer to Figure 32 for the PRI switch model. HDLC signaling is automatically terminated by an internal HDLC.

Default Connections (PRI Mode)

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

Note: The board keyword SwitchConnections can override this setting.

The exact settings for CG 6100C boards configured as T1 or E1 depend upon the NetworkInterface.T1E1[x].SignalingType keyword setting.

The following tables show the default routing for CG 6100C boards configured as T1 or E1 in the PRI mode.

		On CG 6100C boards, the framer signaling is hard wired to internal HDLCs when the board runs in PRI mode. Note: The CG 6100C board does not allow signaling streams to be connected to the CT bus.

5.2.3 CG 6100C Switch Model: RAW Mode

The following diagram shows the CG 6100C switching model in the RAW mode:

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 twenty-four channels.

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

Figure 36. Connecting T1 Timeslots (Raw Mode)

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.

Figure 37 shows how voice channel data is assigned to timeslots:

Figure 37. Connecting E1 Timeslots (RAW Mode)

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 6100C boards configured as E1 depend upon the NetworkInterface.T1E1[x].SignalingType keyword setting.

The following tables show the default routing for CG 6100C boards configured as E1 boards in the RAW mode
