Command Modes

AAL2 trunking

Usage Guidelines

This command establishes a relationship between an endpoint and an LCN/CID pair. The endpoint is bound to a DS0 and the CID binds a DS0 to a logical channel—ensuring an endpoint-to-endpoint trunk. The following conditions must be met before you use this command:

•A previously added endpoint must exist.

•PVC must be of bearer type and provisioned using the addcon command.

•The current DSP template must contain the desired codec type.

This command can be used on an endpoint that has no associated CAS variant. However, if a CAS variant is specified for the endpoint, it must be Q.50 variant (file q50.o)—the only CAS variant supported by this command.

The G.723.1 codecs are supported for VISM-PR cards and are not supported for VISM cards.

Examples

The following example creates a CID for endpoint 10, LCN 140, with a CID number of 10. The codec type is 2 (G.711a), profile type is 1 (ITU), profile number is 1 (ITU), VAD is 1 (on), VAD holdover is 300 milliseconds, type 3 redundancy is 1 (on), CAS transport is 1 (on), DTMF transport is 1 (on), idle code suppression is 1 (on) and the packet period is 10 milliseconds.

addcid 10 140 10 2 1 1 1 300 1 1 1 10

Command Modes

VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking

Usage Guidelines

You must execute the addport and addrscprtn commands before you use this command.

If you are using this command with the VoIP switching/trunking operating mode and dual PVCs, you must add the primary channel before the secondary channel.

If you are using this command with the AAL2 trunking operating mode, the pvc-conn-type argument value must be 1 (AAL5) for signaling and 2 (AAL2) for a bearer channel.

This command requires you to configure the PVC connections in the following ways for the different operating modes:

•VoIP switching/trunking operating mode addcon command configuration requirements:

– One AAL5 PVC connection with an optional secondary AAL5 PVC connection.

•AAL2 trunking operating mode addcon command configuration requirements:

–One AAL2 connection and up to 63 additional optional AAL2 connections to each remote location.

–Up to eight AAL5 connections for CCS signaling across the trunk, if your application requires CCS.

•Switched AAL2 PVC operating mode addcon command configuration requirements:

–One AAL2 connection.

–One AAL5 connection for communication with the call agent and external DNS.

Examples

The following example adds a master connection as the primary channel using AAL2 for bearer traffic. The local VCI is 160 and the remote end is named node1 in slot 4, port 2 with a VPI/VCI of 223/223. The service type is CBR, the sustainable call rate is 500 cps, and the maximum burst rate is 6000 cells.

addcon 160 1 2 2 1000 1 node1.4.2.223.223 1 500 6000

After you execute this command, a typical local connection ID appears as node 1.5.1.0.160, where 160 is the added LCN.

Usage Guidelines

The endpoint on VISM is a logical port that consists of one DS0. The argument values entered in this command create an endpoint ID (endpt-num) which is required by the call agent for sending the xGCP Create Connection command (CRCX) to a VISM card. You can only configure bearer DS0s as endpoints to a previously added line.

---

Note The endpoint number is not equal to the DS0 number of the associated time slot. For example, endpoint 1 could be associated with DS011.

---

If your application requires the VoIP switching/trunking operating mode, you must add the IP address for VISM with the cnfvismip command before endpoints can be added.

This command sends an RSIP message to each associated call agent indicating that the endpoint is in service.

Examples

VoIP switching/trunking, switched AAL2 PVC, AAL2 trunking, and switched ATM AAL1 SVC

Usage Guidelines

---

Note If you are running a VoIP application, you must use the cnfvismip command before you can add endpoints.

---

This command adds a specified number of consecutive endpoints starting at a specified endpoint number, line number, and DS0 number. As endpoints are added, the command uses the next available (not added) endpoint numbers and DS0s. The command does not wrap around DS0 and endpoint numbers.

---

Note The endpoint number is not equal to the DS0 number of the associated time slot. For example, endpoint 1 could be associated with DS011.

---

Ensure that there are enough lines and DS0s before you add endpoints with this command. If you attempt to add more endpoints than are available, only the available endpoints are added. For example, if T1 line 1 is the only line enabled and you attempt to add 25 endpoints, only 24 endpoints are added. Your terminal display shows the actual number of endpoints added.

This command sends an RSIP message to each associated call agent indicating that the endpoints are in service.

Examples

The following example shows that 12 consecutive endpoints are added to line 1, starting at endpoint number 6, DS0 number 12:

addendpts 6 1 12 12

Enables or disables AAL2 subcell multiplexing. It can be one of the following values: •1 = On •2 = Off

Command Modes

AAL2 trunking

Usage Guidelines

When you enable multiplexing, multiple CPS packets are multiplexed onto a single AAL2 connection without partial fill (unless there is a timeout). When you disable multiplexing, each CPS packet fills one or two cells (with padding).

---

Note The field length for each CPS packet can be up to 64 bytes.

---

When the multiplexing type is changed if CIDs are present, the card is reset and existing CIDs/connections are restored with the multiplexing type.

Examples

The following example shows that subcell multiplexing is disabled:

cnfaal2subcellmuxing 2

cnfannpathprefix

To designate the main prefix directory Trivial File Transfer Protocol (TFTP) path from which to retrieve announcement files from the announcement file server, use the cnfannpathprefix command in the VoIP switching operating mode.

cnfannpathprefix ann-prefix-path

Syntax Description

ann-prefix-path

The main directory TFTP path. In the range from the null string to 64 alphanumeric characters.

Command Modes

VoIP switching

Usage Guidelines

The prefix directory path is prefixed to the codec directory and the filename. The path prefix will be relative to the default TFTP directory on the announcement file server. Examples of valid prefix directory paths are:

•<null string>

•vism_ann

•cisco/vism_ann

•/cisco/vism_ann

---

Note The /cisco/vism_ann path starts at the root directory on the announcement file server because it begins with a backslash (/).

---

If you do not use this command, the default TFTP directory on the announcement file server is used as the prefix directory path.

You can use any directory or path on the announcement file server as the main directory for storing announcement files. Take into consideration the following guidelines when you use this command:

•If you do not configure an announcement path prefix on the VISM, the main announcement file directory is the default TFTP directory on the server.

•If you configure a path prefix, it is used as the main announcement directory.

•If the path prefix is not absolute (does not begin with /), then the prefix is relative to the default TFTP directory.

You must configure codec subdirectories under the main announcement directory on the announcement file server. One or more of the following codec subdirectories, for each encoding, are used for announcement files:

•g711u/

•g711a/

•g726_32k/

•g726_24k/

•g726_16k/

•g729_a/

•g7231_high_rate/

•g7231_a_high_rate/

•g7231_low_rate/

•g7231_a_low_rate/

---

Note VISM supports G.729ab for connections and endpoints. If an announcement is to be played on a connection or endpoint provisioned for G.729ab, it must be recorded in G.729a.

---

For example, if the announcement server all-lines-busy.au file is encoded in both g711a and g729a, the following pathnames and files exist on the file server (assuming the default TFTP directory is tftpboot):

•/tftpboot/g711_a/all-lines-busy.au

•/tftpboot/g729_a/all-lines-busy.au

When the call agent requests that the announcement server all-lines-busy.au file be played toward one end of an established call, the VISM determines the codec being used for that call and plays the corresponding announcement file.

When the call agent requests that an announcement be played toward the TDM network on an unconnected endpoint, the codec used is specified by the VISM announcement preferred codec, configured with the cnfannprefcodec command.

You can configure another level of directories to group announcement files by language. Specify these directories by the call agent (or when provisioning the VISM) as part of the announcement file name. For example, the call agent might specify the english/ann1.au announcement file name. If the file is encoded in G.729a and the prefix is /tftpboot, the file is located at /tftpboot/g729_a/english/ann1.au.

Examples

The following example shows that the /cisco/vism_ann path is designated as the prefix directory path from which to retrieve announcement files from the announcement file server:

cnfannpathprefix /cisco/vism_ann

In VISM, 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. It can be in the range from 1 to 99. (Default = 61)
vad-tol	VAD tolerance—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 10. Some examples are: •10000 (tolerance) = 1% (over subscription drop ratio) •100 = 0.01% •10 = 0.001% •1 = 0.0001% It can be in the range from 0 to 10000. (Default = 100)

Command Modes

VoIP switching/trunking and switched AAL2 PVC

Usage Guidelines

A glare condition occurs when two stations attempt to call each other simultaneously. Glare condition resolution involves a terminating VISM, which, upon receiving an off-hook event from the call agent, starts a timer and verifies that the terminating PBX is also attempting an off-hook event. If so, off-hook events from the call agent are ignored for the duration of the timer—the value you indicated with the glaretime argument value.

To use this command, you must ensure that the endpoint indicated by the endpt-num argument value has been previously added, and that the associated DS0 is configured for CAS.

---

Note To use this command, you must choose the MIB as the source in the cnfcasparamsource command.

Command Modes

VoIP switching/trunking and switched AAL2 PVC

Usage Guidelines

Guard time is the minimum duration between the end of one call and the beginning of the next call. When a delete connection (DLCX) command is received from a call agent, VISM starts a timer—set by the value you indicate for the guardtime argument—and ignores any off-hook events until the timer has expired.

To use this command, you must ensure that the endpoint indicated by the endpt-num argument value has been previously added, and that the associated DS0 is configured for CAS.

Usage Guidelines

A wink is composed of the following sequential events:

1. On-hook pattern

2. Off-hook pattern

3. Return to an on-hook pattern

The minimum and maximum make times are the minimum and maximum durations that the off-hook pattern persists. The minimum break time is the minimum duration that the on-hook pattern persists following the return to on-hook.

To use this command, you must ensure that the endpoint indicated by the endpt-num argument value has been previously added, and that the associated DS0 is configured for CAS.

Command Modes

VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking

Usage Guidelines

Specify the cnfclksrc command argument values according to the following rules:

•To configure any line except for line 1 of a VISM card, you must use a VISM-PR card in combination with a PXM1E or PXM45 in your MGX 8000 Series switch chassis.

•If the clock source is the external BITS clock (a T1 or E1 port on the PXM back card), specify the configuration as:

cnfclksrc 7.35 p

---

Note Type 7 for the slot number regardless of the PXM card's location in the chassis. Type 35 for the port number—the BITS port is always port 35.

---

•If the clock source is an external signal on one of the PXM OC3 ports, specify the configuration as:

cnfclksrc 7.n p

---

Note Type 7 for the slot number regardless of the PXM card's location in the chassis. The n port parameter value is the OC3 port number in the range 1 to 4.

---

•If the clock source is the PXM's internal crystal and no other clock source has been specified, do not configure the clock source. The crystal is the automatic default.

•If you want to change the clocking source from external to the PXM card's internal crystal, specify the configuration as:

cnfclksrc 7.X n

---

Note Type 7 for the slot number regardless of the PXM card's location in the chassis. The X argument value is the either 35 or the OC3 port number, depending upon which is the currently specified source. The null port number argument value cancels the previous configuration and returns the clocking source to the default internal crystal.

---

•If the clock source is from a line on a VISM card, specify the configuration as:

cnfclksrc Y.1 p

---

Note The Y argument value is the actual slot number of the VISM card. Always type 1 for port argument value, which represents the line number in this configuration.

---

Refer to the Cisco MGX 8850 Installation and Configuration Guide and the Cisco MGX 8000 Series Switch Command Reference for information on the following PXM card clocking commands:

fx-lco

Local connection option fax preamble response. It can be one of the following values: •1 = VISM controlled T.38, then fax pass through. Upon detecting a fax preamble, VISM first attempts to complete a fax relay on the connection. If fax relay is unsuccessful due to a lack of local resources, T.38 connection admission control (CAC) failure, or the remote side did not acknowledge the 200 Named Signaling Event (NSE), VISM follows the procedure for fax passthrough. If fax relay is successful, the connection is returned to voice mode when the fax end of transfer occurs. •2 = VISM controlled T.38 only. Upon detecting a fax preamble, VISM attempts to complete a fax relay on the connection. If fax relay is unsuccessful, the connection is returned to voice mode. If the fax relay is successful, the connection is returned to voice mode when the fax end of transfer occurs. •3 = Passthrough, then VISM controlled T.38. Upon detecting a fax preamble, VISM first attempts the procedure for fax passthrough. If fax passthrough is unsuccessful due to a lack of local resources or an upspeed CAC failure, VISM attempts the fax relay procedure. If both fax passthrough and fax relay fail, the connection is returned to voice mode. If either fax passthrough or fax relay are successful, the connection is returned to voice mode when the fax end of transfer occurs. •4 = Passthrough only. Upon detecting a fax preamble, VISM attempts the fax passthrough procedure. •5 = Off.

Command Modes

cnflntrunkcond

To enable or disable trunk conditioning for a specified VISM card line, use the cnflntrunkcond command in the VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking operating modes.

cnflntrunkcond line-num trunk-cond-enable

Syntax Description

line-num	Line number of the current VISM card line for which you want to condition a line. It can be in the range from 1 to 8.
trunk-cond-enable	Enables or disables trunk conditioning on a line. It can be one of the following values: •1 = On •2 = Off

Command Modes

VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking

Usage Guidelines

If you enable trunk line conditioning, VISM conditions the affected DS0 when an alarm indication signal (AIS), a blue alarm, is detected on the ATM side. Trunk line conditioning consists of transmitting an idle code pattern for 2.5 seconds followed by the seized code specified in the cnfcascode command.

---

Note This command is not allowed if endpoints or CCS channels are enabled on the line.

---

Examples

The following example shows that trunk conditioning is enabled for line number 6 on the current VISM card:

cnflntrunkcond 6 1

Related Commands

Command	Description
cnfcascode	Configures CAS idle code and seized code parameters for an endpoint.

cnfvbdcodec

To configure voiceband data (VBD) upspeed codec on the current VISM card, use the cnfvbdcodec command in the VoIP switching/trunking operating mode.

cnfvbdcodec upspeed-codec

Syntax Description

upspeed-codec

Upspeed codec. It can be one of the following values: •1 = G.711u (Default for T1 VISM cards) •2 = G.711a (Default for E1 VISM cards) •3 = G.726-32k •4 = Clear channel •5 = G.723.1-H (Valid for template number 4 only) •6 = G.723.1-L (Valid for template number 4 only) •7 = G.726-16k •8 = G.726-24k •9 = G.726-40k

Command Modes

VoIP switching/trunking

Usage Guidelines

VISM uses the configured codec even if, for example, the configured codec is G.726-32k and VISM is preconfigured with G.711. In this case, an actual downspeed would be performed.

If you configure clear channel, VISM does support a mixed system clock—VISM cannot be originated at a T1 line and terminated at an E1 line, or originated at an E1 line and terminated at a T1 line.

When VISM is configured with clear channel, the codec is not used in the fax/modem upspeed session because VISM cannot detect any tones using clear channel.

AAL2 modes obtain the upspeed codec from the AAL2 profile table. AAL1 does not support compression and therefore does not require upspeed.

The G.723.1 codecs are supported for VISM-PR cards and are not supported for VISM cards.

---

Note Cisco recommends that you do not use upspeed-codec argument values 5 or 6 with this command.

---

Examples

The following example shows that the VBD upspeed codec is configured as G.711u:

cnfvbdcodec 1

Related Commands

Command	Description
dspvbdcodec	Displays the upspeed codec used for voiceband data (VBD).

cnfvbdpol

To configure VISM card level voiceband data (VBD) policies—fax/modem carrier loss and fax/modem upspeed connection admission control (CAC) failure—use the cnfvbdpol command in the VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking operating modes.

cnfvbdpol carrier-loss-pol cac-reject-pol

Syntax Description

carrier-loss-pol	Carrier loss policy. It can be one of the following values: •1 = Revert to the previous codec •2 = Maintain the upspeed codec
cac-reject-pol	CAC rejection policy. It can be one of the following values: •1 = Delete the connection •2 = Maintain the connection

Command Modes

VoIP switching/trunking, switched AAL2 PVC, and AAL2 trunking

Usage Guidelines

Follow standard CLI procedures for this command.

Examples

The following example shows that the current VISM card reverts to the previous codec for fax/modem carrier loss events and maintains the connection during upspeed CAC failure events:

cnfvbdpol 1 2

Related Commands

Command	Description
dspvbdpol	Displays the current VISM card level policies for fax/modem upspeed CAC failure and fax/modem carrier loss for call events.

cnfvismdn

To configure the current VISM card domain name, use the cnfvismdn command in the VoIP switching/trunking and switched AAL2 PVC operating modes.

cnfvismdn domain-name

Syntax Description

domain-name

Current VISM card domain name. A text string of 1 to 64 alphanumeric characters. (Default = cisco.com)

Command Modes

VoIP switching/trunking and switched AAL2 PVC

Usage Guidelines

Ensure that you configure the same domain name for the VSC as you do for the VISM card.

The domain name you configure is used when you create an endpoint identification number for each endpoint on a VISM card. The endpoint identification number is used to address SGCP/MGCP commands to a specific endpoint.

If you do not use this command, the default domain name is used.

Examples

The following example shows that the current VISM card is configured with the domain name north:

cnfvismdn north

Related Commands

Command	Description
cnfvismip	Configures the current VISM card IP address.
dspvismdn	Displays the domain name of the current VISM card.

cnfvismip

cnfvismip vip-addr netmask |bearer-ipaddr bearer-netmask|

Syntax Description

vip-addr	Control IP address of the current VISM card, in dotted decimal format (nnn.nnn.nnn.nnn).
netmask	Control local network subnet mask, in dotted decimal format (nnn.nnn.nnn.nnn). It should be assigned the value 255.255.255.248.
bearer-ipaddr	(Optional) Bearer IP address, in dotted decimal format (nnn.nnn.nnn.nnn).
bearer-netmask	(Optional) Bearer IP subnet mask, in dotted decimal format (nnn.nnn.nnn.nnn).

Command Modes

VoIP switching/trunking and switched AAL2 PVC

Usage Guidelines

You must configure the control IP address with this command before adding endpoints.

The VISM card control IP address is used to communicate with the VSC and as an identification for VoIP endpoints.

The configured VISM card IP address and subnet mask values are stored on the MGX 8000 Series platform PXM card hard disk and retrieved for subsequent configuration commands.

If you do not specify a bearer IP address and subnet mask, the control IP address and subnet mask are used as both control and bearer.

Examples

The following example shows that the current VISM card is configured with control IP address 209.165.200.224 and subnet mask 255.255.255.248:

cnfvismip 209.165.200.224 255.255.255.248
