V.92 Modem on Hold for Cisco AS5350, Cisco AS5400, and Cisco AS5850 Universal Gateways and Cisco AS5800 Universal Access Servers
Feature History
This feature module introduces the V.92 International Telecommunication Union Telecommunication Standardization Sector (ITU-T) standard Modem on Hold (MOH) feature on NextPort/DFC-108NP-bearing platforms for use with Cisco IOS Releases 12.2(2)XB1 and 12.2(11)T.

Feature Overview
V.92
To remain current with industry needs, the ITU-T V.90 modem standard recommendations have been enhanced. The new standard, V.92, meets the need for a digital modem and analog modem pair on the Public Switched Telephone Network (PSTN). V.92 improves the upstream data signaling rate and adds new features that enhance modem usability. These new modem protocols and standards are implemented at the modem level.
This feature module introduces the V.92 Modem on Hold feature on Cisco AS5350, Cisco AS5400, and Cisco AS5850 universal gateways and Cisco AS5800 universal access servers.
Note
NextPort firmware provides V.92 capabilities bundled with existing NextPort features. The NextPort Dial Feature Card (DFC-108NP) is responsible for the ITU implementation of V.92 and the collection of statistics related to the new features, including the new Modem States that occur with the additional negotiations for V.92. The statistics are collected by the dial feature card (DFC) but are passed to and stored in Cisco IOS software. Cisco IOS software is responsible for controlling the features and displaying the new statistics.
The Cisco AS5800 uses the NextPort high density dial termination card to implement this feature. Both voice and dial technologies are supported when used in a Cisco 5850 universal gateway.
Note
Modem on Hold
V.92 Modem on Hold allows a dial-in customer to suspend a modem session to answer an incoming voice call or to place an outgoing call while engaged in a modem session. When the dial-in customer uses Modem on Hold to suspend an active modem session to engage in an incoming voice call, the Internet service provider (ISP) modem listens to the original modem connection and waits for the dial-in customer's modem to resume the connection. When the voice call ends, the modem signals the telephone system to end the second call and return to the original modem connection, then the modem signals the ISP modem that it is ready to resume the modem call. Both modems renegotiate the connection, and the original exchange of data continues.
Note
Use of the V.92 Modem on Hold feature for Cisco NextPort firmware can be controlled globally using AT commands (modemcaps) or can be controlled on a per-caller basis using the RADIUS distributed client/server system.
Note
The following sections contain information about controlling the V.92 Modem on Hold feature:
•
AT Commands (Modemcaps) and S-Registers
V.92 Modem on Hold is disabled by default and is controlled with standard AT commands and S-registers. V.92 is enabled and disabled with the S29 S-register (S29 = 12), and Modem on Hold is controlled with the S62 S-register (S62 must be set to enable Modem on Hold). AT commands download the configuration to the modem at the end of every call. The ATSn=v and ATSn? AT commands are used to configure V.92 Modem on Hold on NextPort platforms. Table 1 lists additional S-register parameters used to enable and disable the feature.
To disable V.92 Modem on Hold, you can use a modemcap (for example, s62=0s63=3s21=15s29=12) or set the S29 register to any number other than 12. You can also use the RADIUS vendor-specific attribute (VSA) to disable Modem on Hold if the feature was initially enabled by the default value (modemcap).
Note
For detailed information about the AT commands and S-registers used to control V.92 on NextPort platforms, refer to the AT Command Set and Register Summary for NextPort Platforms.
RADIUS Authorization
Per-user control of Modem on Hold can be configured for caller authorization using a RADIUS server. RADIUS servers use the vendor-specific attribute (VSA) capability to configure Modem on Hold for individual users. The current attribute=value protocol syntax has been extended with the new
Modem on Hold attribute. You can enter the following value for this attribute:•
Note
Alternatively, you can enter the inf keyword, which allows the modem to remain on hold indefinitely.
If the Modem on Hold configuration is not present, or if it is not syntactically correct, the modem uses its default configuration for Modem on Hold. The default operation can be modified by using a modemcap string. Following authentication of a dial-in user, an additional control command is sent to the modem if the dial-in user does not have a default Modem on Hold configuration.
Note
V.92 Modem on Hold running on systems using RADIUS authorization increases the length of RADIUS response packets by approximately 20 bytes. RADIUS databases increase in size by approximately the same amount for each dial-in user with a nondefault Modem on Hold attribute value.
With RADIUS, authentication and authorization occur as part of the same process. When a caller connects to the access server, the caller enters a user ID and password in response to prompts from the access server. This information is formatted as a RADIUS request packet and is sent to the appropriate RADIUS server. If the user ID is valid and the password matches, the RADIUS server responds with a packet containing authorization data for the connection. This authorization data contains the Modem on Hold configuration if it is present in the RADIUS database.
The access server interprets the response from the RADIUS server and performs any actions associated with the authorization data. For Modem on Hold, a command is sent from the Cisco IOS host to the NextPort channel to set the Modem on Hold parameters. No confirmation from the channel is required.
When the client modem requests a Modem on Hold operation, the modem switches to an on-hold state, which prevents further data from being queued to the connection. When the Cisco IOS software receives the request to go on hold, any transmit packets queued to local Cisco IOS queues (packets not already posted to the queues shared between the Cisco IOS software and the modem) are discarded. This mechanism reduces the possibility that stale data will be transmitted to the modem when the connection is reactivated. It also reduces the number of buffer resources that are tied up while a modem is on hold.
Note
The value of the attribute is the number of seconds allowed for the on-hold state. This value is rounded by the Cisco IOS software to one of the permissible values. The number can be replaced with the inf command, which allows unlimited on-hold time. Case is significant for both attribute names and values.
Note
Configuring V.92 Modem on Hold with RADIUS
If you use RADIUS to configure the Modem on Hold feature, use the modem-on-hold attribute, where the VALUE attribute is a nonnegative integer in seconds for maximum time on hold allowed. VALUE can be one of the following:
•
•
The following example shows RADIUS enabled where Modem on Hold is optional:
vendor-specific=9:1:modem-on-hold*VALUE
Note
# This user can use MOH without time limits. (inf)# MOH capability is not required for the connection (*)testi Auth-Type = Local, Password = "test"Service-Type = Login-User,Cisco-AVPair = "modem-on-hold*inf"# This user can use MOH for 30 seconds.# MOH capability is not required for the connection.test30 Auth-Type = Local, Password = "test"Service-Type = Login-User,Cisco-AVPair = "modem-on-hold*30"# This user can not use MOH.# MOH capability is not required for the connection.test0 Auth-Type = Local, Password = "test"Service-Type = Login-User,Cisco-AVPair = "modem-on-hold*0"# This user can not use MOH.# But MOH capability IS required for the connection.# If the user logs on to a device that does not support# MOH (eg the console), he will be disconnected after# authentication.testr Auth-Type = Local, Password = "test"Service-Type = Login-User,Cisco-AVPair = "modem-on-hold=0"# This user gets the default MOH setting.# The default setting is disabled, unless overridden# by a modemcap entry.testx Auth-Type = Local, Password = "test"Service-Type = Login-User# This user can go on hold for 60 seconds# in a PPP link. The service type determines# which calls get the MOH setting.lucy Auth-Type = Local, Password = "test"Service-Type = Framed-User,Cisco-AVPair = "modem-on-hold*60"
Note
For more information about using RADIUS, refer to the Configuring RADIUS documentation.
Modem Enhancements for V.92 Modem On Hold
The following modem enhancements have been made for the implementation of the
V.92 Modem on Hold feature:•
Disconnect Reasons
V.92 Modem on Hold Disconnect Reasons is the method by which a modem tells the Cisco IOS software (host) why it has terminated its session with a client through the Modem on Hold cleardown by modem and the Modem on Hold timeout values. Table 2 lists the new Modem on Hold Disconnect Reasons.
Table 2 Modem On Hold Disconnect Reasons
DR_MOH_CLRD
Modem On Hold cleardown by modem
DR_MOH_TIMEOUT
Modem On Hold timeout value reached
Duration Limit Timer
The Modem on Hold duration limit timer is supported within dialed number ID service (DNIS), calling line ID (CLID), RADIUS (but not TACACS+), and global resource pool manager server (RPMS) virtual groups. This support permits ISPs to associate the Modem on Hold feature and its timer limit according to customer needs. When the Modem on Hold timer is active (a modem is on hold), it must take precedence over the idle timer. For example, if the idle value is five minutes and the Modem on Hold duration limit is ten minutes, the customer is permitted to be on another call for up to ten minutes without being disconnected after five minutes by the idle timer. The Modem on Hold timer value resets at the end of each on-hold session.
Modem on Hold Link Information Parameters
Modem States
This feature supports modem states, which are discrete states that a modem transitions through, during, and after negotiation with a client modem. These states include the Modem on Hold input state, the Steady input state, and the Steady, Steady Retrain, and Terminate output states.
New and Modified MIBs
Existing MIBs that show the status of modem settings have been extended to show V.92 Modem on Hold configuration status. New MIBs have been created to report the incidence of V.92 Modem on Hold request calls coming into the server and to monitor on-hold status.
Supported Module Firmware and Cisco IOS Software
V.92 Modem on Hold is supported on the following firmware and software:
•
•
Benefits
Allows Voice Calls Without Interruption of Existing Modem Connection
V.92 Modem on Hold allows the origination and reception of voice calls without disturbing preexisting modem sessions. With Modem on Hold, calls can ring through to the dial-in user without requiring the expense of a second telephone line.
Per-Use Enabling
Service providers can enable Modem on Hold on a per-user basis for premium service opportunities.
Standard Modem Feature
V.92 is a standard modem feature that is offered as a no-cost upgrade to the installed system.
V.92 Compatibility
Modems that support V.92 are fully compatible with modems that do not support it. If a modem that supports Modem on Hold connects with a modem that does not support it, the modems will connect normally. However, the Modem on Hold function is not available for that call.
