AAL2 Trunking Mode

This section contains the following tasks for configuring the VISM/VISM-PR card for AAL2 trunking:

• Configuring the Operating Mode

• Configuring the ATM Network Side

• Configuring TDM Side Signaling for Applications That Use CCS

• Configuring TDM Side Signaling for Applications That Use CAS

• Adding DS0 Endpoints to Lines

• Adding CIDs

• Modifying the Profile Table

Sample AAL2 trunking configurations are shown in the "Sample Configuration" section.

Configuring the Operating Mode

To configure the correct operating mode for your VISM/VISM-PR card, complete the following steps:

Step 1 To configure the VISM/VISM-PR operating mode, enter the cnfvismmode command.

nodename.1.28.VISM8.a > cnfvismmode <mode_number>

Replace <mode_number> with value of 2.

•1 = VoIP switching/VoIP trunking (default)

•2 = AAL2 trunking

•3 = AAL1 switching

•7 = Switched AAL2 SVC

•8 = Switched AAL2 PVC

•9 = VoIP and AAL1 SVC

•10 = VoIP trunking and AAL2 trunking

Step 2 Type a y at the following message:

WARNING: Available CLI Commands will be changed, do you want to proceed (Yes/No)? y

A message about the number of available commands displays before the card returns the prompt. The following example shows the number of available commands for AAL2 trunking mode:

INFORMATION: The new 'aal2Trunking' mode has 226 CLI commands.

Step 3 To enable or disable subcell multiplexing, enter the cnfaal2subcellmuxing command.

nodename.1.28.VISM8.a > cnfaal2subcellmuxing <muxing status>

Replace <muxing status> with one of the following values:

•1 = On

•2 = Off

Step 4 To display the current VISM/VISM-PR operating mode and subcell multiplexing status, enter the dspvismparam command.

Configuring the ATM Network Side

Configuring the ATM network side consists of setting up ATM PVCs across the network and providing the mechanism by which calls are routed over the correct PVC.

Each PVC is set up as three segments: two local segments and one network segment. The local segments are set up between the two VISM cards (one at each end of the PVC) and their respective PXM cards. The network segment is set up between the two PXM cards across the network.

For more information about PXM1E or PXM45 segments, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Configuration Guide, Release 5.1.

For more information about PXM1 segments, refer to the Cisco MGX 8850 Edge Concentrator Installation and Configuration, Release 1.1.3.

The AAL2 trunking operating mode supports as many as 64 AAL2 PVCs connected to each remote endpoint in the network. The PVCs carry voice traffic and optional channel-associated signaling (CAS).

PVCs can be established in a non PNNI environment (PXM1) and a PNNI environment (PXM1E/PXM45).

General Guidelines

Use the following guidelines when you set up the ATM side in the AAL2 trunking mode:

•Add the slave connection first; then add the master connection.

Note the slave connection ID, which you need to set up the master connection. In a non PNNI environment, the slave connection is the PXM1 card. In a PNNI environment, the slave connection is the remote gateway.

•Create connection identifiers (CIDs) for each PVC. CIDs bind the endpoints to the PVC.

Note CID numbers must match on the master and slave sides.

Calls that arrive at a specific DS0 are automatically routed to the preconfigured CID and PVC over trunks.

•The master and slave connection base parameters, PCR, SCR, and MBS values must match.

If these values do not match, PXM1E and PXM45 cards display an error. PXM1 cards do not display an error.

•If the connections are through a physical loopback on a PXM line, make sure that the VPI and VCI values are the same on both ends of the loopback.

Complete the following tasks to configure the ATM side:

• Configuring PVC Connections

• Connection CAC Configuration

Configuring PVC Connections

The AAL2 trunking mode has the following two types of PVCs:

•AAL2—Supports bearer data; supports signaling data in clear channel codec mode.

•AAL5—Supports signaling data.

Complete the following steps to configure PVC connections:

Note You must add the slave connection first before adding the master connection. Retain the remote connection ID to use when setting up the master connection.

Step 1 To add an ATM PVC between the VISM card and the MGX 8000 Series platform PXM card, enter the addcon command.

nodename.1.28.VISM8.a > addcon <localVCI> <preference> <pvcType> <application> <PCR> <mastership> |<remoteConnId> <serviceType> <scr> <mbs> <priority> <prefrte> <direct>|

Table 6-3 Parameters for cnfconcacparams Command

Parameter

Description

LCN

Logical channel number (LCN) of the connection. Range is 131-510.

VADTolerance

VAD tolerance is the expression for VAD over-subscription drop ratio, where tolerance = 10000 x over-subscription drop ratio (expressed as a percentage).

A typical value for VAD tolerance is 100. Some examples are:

•10000 (tolerance) = 1% (over-subscription drop ratio)

•100 = 0.01% (default)

•10 = 0.001%

•1 = 0.0001%

Range is 0-10000.

VADDutyCycle

VAD duty cycle is the ratio of speech and holdover duration to the total duration expressed as a percentage.

Holdover is the period after silence begins, and silence suppression is turned on. In VISM/VISM-PR, the holdover time is 250 ms.

A typical value for this parameter is 61 which means that 61% of the time is taken by speech and holdover. Range is 1-99. Default is 61.

Configuring TDM Side Signaling for Applications That Use CCS

Common channel signaling (CCS) uses a dedicated channel on a DS1 line to carry the signaling for the other channels on the line. Signaling is transported across the trunk as Q.931 messages in ATM cells using AAL5.

You must identify the signaling channel to the VISM/VISM-PR card.

To add a CCS channel to your VISM/VISM-PR card, enter the addccs command.

nodename.1.28.VISM8.a > addccs <line_number> <ds0_number> <LCN>

Replace the above arguments with the values listed in Table 6-4.

Table 6-4 Parameters for addccs Command

Parameter

Description

line_number

Line number. Range is 1-8.

ds0_number

Logical channel number of the CCS channel to be added. Range is 131-510.

Configuring TDM Side Signaling for Applications That Use CAS

In AAL2 mode basic CAS configurations are not required.

Adding DS0 Endpoints to Lines

The number of DS0s you can add depends on the template that you are using.

•10 ms

•20 ms

•30 ms

Note The pktPeriod argument applies only to G.729a compression (codec_type argument value = 4). If you have selected any other compression value, ignore this argument.

Step 2 To verify the CIDs you added, enter the dspcids command.

nodename.1.28.VISM8.a > dspcids <LCN>

Replace the <LCN> argument with a value in the range 131-510.

The following example shows sample CID information for LCN 131.

Replace the <LCN> argument with a value in the range 131-510.

Replace the <cidNum> argument with a value in the range 8-255.

The following example shows the values for CID 131.

nodename.1.28.VISM8.a > dspcid 131
LCN number : 131

Modifying the Profile Table

A profile table is associated with each AAL2 operating mode. This profile table specifies the encoding format, which tells the card how to interpret the packets.

You can use the dspaal2profile command to see the values for a profile type. Example 6-1 shows the default values for ITU profile type 1.

Example 6-1 Default Values for ITU Profile 1

nodename.1.28.VISM8.a > dspaal2profile 1 1

UUI Packet Packet Seq. No.
Codepoint Length Time Interval
Range (octets) Codec SID M (ms) (ms)
0-15 40 PCMU No SID 1 5 5
0-15 40 PCMA No SID 1 5 5

Table 6-7 describes the fields shown in the display.

Table 6-7 dspaal2profile Field Descriptions
