Configuring Resource Management

DNIS numbers (800 numbers if applicable).
Type of calls the customer(s) will accept (speech, digital, V.110, V.120).
Exact name of the resource group(s) for this customer or service type and modem specifications (if applicable). This information will depend on the resources that exist on the NAS and the level of services you will offer.

Note

Customer profile information—Number of standard sessions, number of overflow sessions, and how additional calls are treated.

Creating a Customer Profile

For DNIS-based resource management, the customer profile acts as the session control mechanism for Cisco RPMS. The customer profile contains the number of sessions and overflow sessions, how additional calls are treated, and threshold settings. After creating and configuring the customer profile, add DNIS and resource groups.

Note Alerts are generated when thresholds are exceeded. Because 100% can never be exceeded, setting a threshold to 100% is equivalent to disabling it.

To create a customer profile, follow these steps:

Step 1 Select Configuration:Customers and click Add Customer.

The Add a New Customer Profile page appears.

Step 2 Enter the name of the customer or the service type and a description. The Description field is for informational purposes and has no effect on the operation of Cisco RPMS.

Note

Step 3 Enter the maximum number of standard sessions in the Session Count Size Limit field. For unlimited sessions, select No Limit.

Step 4 Enter the Session Count Threshold (in percent). When this threshold is exceeded, an alert notification is generated. For example, if the session size is 100 and the threshold is 85%, an alert will be generated when 86 or more sessions are logged on simultaneously.

Step 5 Enter the maximum number of overflow sessions in the Overflow Size Limit field. For unlimited sessions, select No Limit.

Overflow sessions are useful for billing excess sessions at a premium rate. For example, if a customer is having a special event and many people are expected to request remote access, you could set the overflow sessions to No Limit and charge a premium rate for the excess bandwidth requirements.

Step 6 Enter the Overflow Threshold. When this threshold is exceeded, an alert notification is generated. For example, if the overflow size is 10 and the threshold is 80%, an alert will be generated when 9 or more overflow sessions are logged on simultaneously.

Step 7 Enter the Overflow Call Rejection Threshold. When this threshold is exceeded, an alert notification is generated. For example, if the threshold is 70% and 71% of overflow calls are rejected, an alert will be generated.

Step 8 Enter the Call Rejection Threshold (in percent). When this threshold is exceeded, an alert notification is generated. For example, if the threshold is 30% and 31% of calls are rejected, an alert will be generated.

Step 9 Click Add. The customer profile is created.

Create a DNIS group and add DNIS numbers to the group. See the "Creating a DNIS Group" section.

Creating a DNIS Group

DNIS Groups contain a list of DNIS numbers (telephone numbers used to access the NASes) that belong to a customer. To create a DNIS group and add it to a customer profile, complete the following procedures:

Create a DNIS group
Add DNIS numbers to the DNIS group
Add the DNIS group to a customer profile

Creating a DNIS Group

DNIS groups are convenient for organizing DNIS numbers for a customer. Because multiple DNIS groups can be added to a customer profile, all DNIS numbers can be added to a single DNIS group or they can be subdivided by call type (bearer capability), geographical area, division, and so on.

Note To strictly separate the types of calls that are received for each DNIS group and its associated DNIS numbers, create a separate DNIS group for each call type and use call discrimination to block other call types. For more information, see "Configuring Call Discrimination."

Customer profiles that use a DNIS-based resource management must have at least one DNIS group. To create a DNIS group, follow these steps:

Step 1 Select Configuration:DNIS and click Add DNIS Group.

The Add a New DNIS Group page appears.

Step 2 Enter a name for the DNIS group. To easily identify DNIS groups, include the customer's name within the group name.

Note

Step 3 Enter a description for the DNIS group. The Description field is for informational purposes and has no effect on the operation of Cisco RPMS.

Step 4 Trunks might not provide the call type to NASes. When this happens, the NAS informs the Cisco RPMS that this is a channel associated signaling (CAS) call.

If the trunk does not provide a call type, the Cisco RPMS should be configured to specify a call type for this DNIS group. Select one of the following call types from the CAS Call Override Type list box:

None
Speech (modems)
digital
V.110
V.120

Note For add additional call types, see the

"Adding Call Types" section

Step 5 Click Add.

The DNIS Group is Added. To add DNIS numbers to the group, see the "Adding DNIS Numbers" section.

Adding DNIS Numbers

To add DNIS numbers to a DNIS group, follow these steps:

Step 1 Select Configuration:DNIS and click the DNIS group's DNIS Numbers button.

Step 2 Enter a DNIS number as it appears from the end office switch in the DNIS Number field. DNIS numbers sent from an end office switch are usually a single block of numbers that includes the area code and no delimiters (for example, spaces, hyphens, periods, and commas).

Step 3 Enter the 800 number used to access this DNIS number in the Reference # field. This field is optional and does not affect the operation of the Cisco RPMS. However, if an 800 number is used to access this DNIS number, this field is very useful for isolating problems.

Step 4 Click Add to DNIS Group.

Step 5 Repeats Steps 2 through 4 for each DNIS number to include in this DNIS group.

Note To edit a DNIS number, click the DNIS number's Edit DNIS button. To delete a DNIS number, click the DNIS number's Delete DNIS Number button.

Adding DNIS Groups to a Customer Profile

After creating one or more DNIS groups and adding DNIS numbers, add the DNIS group(s) to the customer profile. To add a DNIS group to a customer profile, follow these steps:

Step 1 Select Configuration:Customers and click the customer profile's DNIS Groups and Call Types button.

The Valid DNIS Group & Call Type Pairs page appears.

Step 2 Select a DNIS group from the list box.

Step 3 Select the call type. This can include speech (modems), digital, V.110, V.120, or other technologies supported by the NAS. For information on adding new call types, see the "Adding Call Types" section.

Step 4 Click Add to Customer.

The DNIS group is added to the customer profile and appears in the DNIS group list.

Step 5 Repeat Steps 2 through 4 to add additional DNIS groups to the customer profile.

Configuring Resources

Resource groups are pointers to resources on NASes and can be associated with resource services (strings returned to modems).

To create a resource group, complete the following procedures:

Create a resource group on a NAS. For more information, refer to the Cisco Resource Pool Manager Feature Module
Create a resource group on the Cisco RPMS (a pointer to the resource group on the NAS)
Create a resource service (if applicable)
Add the resource groups and service to the customer profile

Note In areas where tariffs differ between voice and data calls, it is prudent to use the speech capability of an ISDN line to deliver data calls. Consequently, Cisco RPMS supports Data over Voice Bearer Service (DOVBS). To enable DOVBS, configure the resource group call type as speech, but point to a digital resource group on the NAS.

Creating Resource Groups on the Cisco RPMS

Resource groups are pointers to resources on the NAS(es). To establish a resource group, follow these steps:

Step 1 Select Configuration:Resources:Groups and click Add Resource Group.

The Add a New Resource Group page appears.

Step 2 Enter the name of the resource group in the Resource Group Name field. This name must EXACTLY match a resource group that exists on the NAS.

Note

Step 3 Enter a description of the resource group in the Description field. This field is for informational purposes and does not affect the operation of Cisco RPMS.

Step 4 Click Add.

Step 5 Repeat this procedure for each resource group.

Creating Resource Services

Resource services are used to send modem settings to a NAS. These include minimum speed, maximum speed, modulation, error correction, and compression settings.

Note Resource services are only for use with modems.

To create a resource service string, follow these steps:

Step 1 Select Configuration:Resources:Services and click Add Resource Service.

The Add a New Resource Service page appears.

Step 2 Enter a name for the resource service.

Step 3 Enter a description for the resource service. The Description field is for informational purposes and does not affect the operation of Cisco RPMS.

Step 4 Enter modem in the Service Parameters field. Then enter the following:

Note

Enter min-speed followed by the minimum speed that any modem can use to access the NAS (minimum supported speed: 300 baud). To allow any minimum speed, enter any.
Enter max-speed followed by the maximum speed that any modem can use to access the NAS (maximum supported speed: 56000 baud). To allow any maximum speed, enter any.
Enter modulation followed by the type of modulation that can be used to access the NAS (v34, v90, k56flex, v22bis, v32bis, any).
Enter error-correction followed by the type of error correction that can be used to access the NAS (mnp4, lapm, none, any).
Enter compression followed by the type of compression that can be used to access the NAS (mnp5, v42bis, none, any).

: Note: To use MNP5 compression, MNP4 error correction must be enabled.

Note

any

For example, to configure a NAS to allow any minimum speed, allow a maximum speed of 56000, use V.90 modulation, use MNP4 error correction, and disallow any compression, enter the following:

modem min-speed any max-speed 56000 modulation v90 error-correction mnp4 compression none

Note The

minimum speed supported by NASes is 300 baud. If you are using Point-to-Point Protocol (PPP), the minimum speed is 1200 baud.

Step 5 Click Add.

Step 6 Repeat this procedure for each resource service that you want to create.

Note Resource services are not required for modem resource groups. If you omit a resource service, it is equivalent to setting all parameters to any.

Adding Resource Groups to a Customer Profile

To add a resource group to a customer profile, follow these steps:

Step 1 Select Configuration:Customers and click the customer profile's Resource Data button.

The Valid Resource Data page appears.

Step 2 Select a resource group from the list box.

Step 3 Select a call type that is supported by this resource group.

Step 4 If this resource group supports modem (speech) or V.110 calls, select a resource service string that will be returned to the NAS from the Resource Services list box.

Step 5 Click Add to Customer.

Step 6 Repeat Steps 2 through 5 for each call type that is supported by this resource group.

Step 7 Repeat this procedure for each resource group that you want to add to this customer profile.

Default Customer Profile Resource Management

Configuring default customer profile resource management involves the following:

Creating a default customer profile for each supported call type
Configuring a resource group and adding it to the customer profile

Before You Begin

Before configuring default customer profile resource management, make sure you have information for creating each default customer profile. This includes the exact name(s) of the resource group(s) each default customer profile will use, the types of calls that will be accepted, and modem specifications (if applicable).

Creating a Default Customer Profile

After a call is answered, the NAS sends a request to the Cisco RPMS for Virtual Private Dial-Up Network (VPDN) information based on a domain name or DNIS number. If the Cisco RPMS cannot find VPDN information, the NAS uses the DNIS or domain name to attempt to build a VPDN tunnel locally or from the AAA server.

If the NAS cannot get VPDN information from the Cisco RPMS, locally, or from a AAA server, the NAS assumes the call is a retail dial customer and authenticates the call with the local AAA server.

If one of your strategies involves answering all calls and using the VPDN group or the local AAA server for session control, create a default customer profile. A default customer profile automatically configures the NAS to accept all calls from DNIS numbers that are not assigned to a customer.

To create a default customer profile, follow these steps:

Step 1 Select Configuration:Customers and click Add Customer.

The Add a New Customer Profile page appears.

Step 2 Enter a name for the default customer profile. For example, "Default CP Digital."

Note

Step 3 Set Session Count Size Limit to No Limit.

Step 4 Click the Customer DNIS Group Call Data button.

The Valid DNIS Group & Call Type Pairs page appears.

Step 5 Select default from the DNIS Groups list box.

Step 6 Select the types of calls that will be handled by the default customer profile from the Call Types list box.

Step 7 Click Add to Customer. The default customer profile is created.

Configure resources for the default customer profile. See the "Configuring Resources for a Default Customer Profile" section.

Step 8 Repeat this procedure for each call type that requires a default customer profile.

Note To configure how calls are handled when no customer profile is available for an incoming call, see the "Configuring Cisco RPMS Settings" section.

Configuring Resources for a Default Customer Profile

Resource groups are pointers to resources on NASes and can be associated with resource services (configuration strings returned to modems).

To create a resource group for the default customer profile, complete the following procedures:

Create a resource group on a NAS. For more information, refer to the Cisco Resource Pool Manager Feature Module
Create a resource group on the Cisco RPMS (a pointer to the resource group on the NAS)
Create a resource service (if applicable)
Add the resource groups and service to the customer profile

Note In areas where tariffs differ between voice and data calls, it is prudent to use the speech capability of an ISDN line to deliver data calls. To enable Cisco RPMS to answer digital calls as speech calls, configure the resource group call type as speech but point to a digital resource group on the NAS.

Note To use an existing resource group, skip to the "Adding the Resource Group to a Default Customer Profile" section.

Creating Pointers to Resource Groups on the NAS

To establish a resource group, follow these steps:

Step 1 Select Configuration:Resources:Groups and click Add Resource Group.

The Add a New Resource Group page appears.

Step 2 Enter the name of the resource group in the Resource Group Name field. This name is case sensitive and must EXACTLY match a resource group that exists on the NAS.

Note

Step 3 Enter a description of the resource group in the Description field. The Description field is for informational purposes and has no effect on the operation of Cisco RPMS.

Step 4 Click Add.

Step 5 Repeat this procedure for each resource group.

Creating Resource Services

Resource services are used to return modem settings to a NAS. These include minimum speed, maximum speed, modulation, error correction, and compression settings.

Note Resource services are only for use with modems.

To create a resource service string, follow these steps:

Step 1 Select Configuration:Resources:Services and click Add Resource Service.

The Add a New Resource Service page appears.

Step 2 Enter a name for the resource service.

Step 3 Enter a description for the resource service. The Description field is for informational purposes and has no effect on the operation of Cisco RPMS.

Step 4 Enter modem in the Service Parameters field. Then enter the following:

Note

Enter min-speed followed by the minimum speed that any modem can use to access the NAS (minimum supported speed: 300 baud). To allow any minimum speed, enter any.
Enter max-speed followed by the maximum speed that any modem can use to access the NAS (maximum supported speed: 56000 baud). To allow any maximum speed, enter any.
Enter modulation followed by the type of modulation that can be used to access the NAS (v34, v90, k56flex, v22bis, v32bis, any).
Enter error-correction followed by the type of error-correction that can be used to access the NAS (mnp4, lapm, none, any).
Enter compression followed by the type of compression that can be used to access the NAS (mnp5, v42bis, none, any).

: To use MNP5 compression, MNP4 error correction must be enabled.

For example, to configure a NAS to allow any minimum speed, allow a maximum speed of 56000, use V90 modulation, use MNP4 error correction, and disallow any compression, enter the following:

modem min-speed any max-speed 56000 modulation v90 error-correction mnp4 compression none

Note

Step 5 Click Add.

Step 6 Repeat this procedure for each resource service that you want to create.

Adding the Resource Group to a Default Customer Profile

To add a resource group to a default customer profile, follow these steps:

Step 1 Select Configuration:Customers and click the customer profile's Resource Data button.

The Valid Resource Data page appears.

Step 2 Select a resource group from the list box.

Step 3 Select a call type that is supported by this resource group.

Step 4 If this resource group supports modem (speech) or V.110 calls, select a resource service string that will be returned to the NAS from the Resource Services list box.

Step 5 Click Add to Customer.

Step 6 Repeat Steps 2 through 5 for each call type that is supported by this resource group.

Step 7 Repeat this procedure for each resource group that you want to add to this default customer profile.
