map-class dialer
To define a class of shared configuration parameters associated with the dialer map command for outgoing calls from an ISDN interface and for PPP callback, use the map-class dialer command in global configuration mode.
map-class dialer class-name
no map-class dialer class-name
Syntax Description
class-name |
Unique class identifier. |
Command Default
Command is disabled; no class name is provided.
Command Modes

11.0 |
This command was introduced. |
Usage Guidelines
The class-name argument in the map-class dialer command used to specify the class must be the same as a class-name argument used in a dialer map command.
This command is used on the PPP callback server, not on the callback client.
This command is used to define classes of calls for PPP callback for dial-on-demand routing (DDR), for ISDN Advice of Charge, and for Network Specific Facilities (NSF) call-by-call dialing plans.
For NSF call-by-call support on ISDN Primary-4ESS switches only, use one of the dialing-plan keywords listed in Table 1 .

Examples
The following example configures the PPP callback server on an ISDN BRI interface on a router. The callback server requires an enable timeout and a map class to be defined.
ip address 10.1.1.7 255.255.255.0
dialer map ip 10.1.1.8 name mymap class dial1 81012345678901
dialer callback-server username
The following example configures the ISDN switch type to Primary-4ESS and configures ISDN PRI on T1 controller 1/0, and sets the D channel for dialer map classes that reference the NSF dialing plans. Finally, the map-class dialer command uses a dialing plan keyword and the dialer outgoing command refers to the same plan.
isdn switch-type primary-4ess
description This is the DMS D-channel 415-886-9503
ip address 10.1.1.3 255.255.255.0

dialer map ip 10.1.1.4 name hismap class accuplan 14155773778
map-class dialer megaplan
map-class dialer accuplan
The following partial example configures BRI interface 0 to function as the callback server on the shared network. The callback server requires an enable timeout and a map class to be defined.
ip address 10.2.1.7 255.255.255.0
dialer map ip 10.2.1.8 name mymap class dial1 81012345678901

Usage Guidelines
If you mark a modem as inoperable, it appears as Bad—without the asterisk (*)—in the Status column of the show modem command output. A modem marked inoperable by the modem startup-test command appears as Bad* in the show modem command output. Use the no modem bad command to unmark a modem as Bad* or Bad and restore it for dialup connection services.
Note
Only idle modems can be marked bad by the modem bad command. If you want to mark a modem bad that is actively supporting a call, first issue the modem shutdown command then issue the modem bad command.
Examples
The first part of the following example shows a successful connection between modem 2/1 and modem 2/0, which verifies normal operating conditions between these two modems. However, when modem 2/1 is tested against modem 2/3, the back-to-back modem test fails. Therefore, modem 2/3 is suspected or proven to be inoperable. Modem 2/3 is removed from dialup services through the use of the modem bad command on line 28.

Command History
|
|
11.3(2)AA |
This command was introduced. |
Usage Guidelines
The modem busyout-threshold command functionality is also often termed autobusyout. This command applies to all DS0 lines coming into the router and counts all free modems in all pools.
The modem busyout-threshold command periodically checks to determine if the number of free modems is less than the user specified threshold and if it is it ensures that the number of free DS0 channels is less than or equal to the number of modems.
This command should be used only where excess calls to one router are forwarded by the exchange to an additional router on the same exchange group number.
Because the modem busyout-threshold command checks only periodically, the threshold should be greater than the number of calls the user expects to receive in 1 minute plus a safety margin. For example, if the user receives an average of 10 calls per minute, then a threshold of 20 would be advised. Very small thresholds should be avoided because they do not allow sufficient time for the exchange to respond to out-of-service notifications from the router, and callers may receive busy signals when free modems are all used.
Caution
The number of DS0 lines in normal operating conditions should be approximately equal to the number of modems (for example, within 30). If this is not the case, it will cause a lot of messaging traffic to the exchange and may cause active calls to be dropped. This caution is not a concern for short periods, that is, when modem cards are replaced.
On T3 controllers, any contained T1 controllers that are not in use should be undeclared to remove them from the autobusyout list.
Note
On T3 controllers, any contained T1 controllers that are not in use should be undeclared to remove them from the autobusyout list.This command is the same as the ds0 busyout-threshold command for the Cisco AS5300 and AS5800 access servers.
Examples
The following example shows how you might configure the modem busyout-threshold command:
modem busyout-threshold 30

Command History
|
|
10.0 |
This command was introduced. |
Usage Guidelines
In response to the RING signal, the router raises the DTR signal, which indicates to the modem that it should answer the call. At the end of the session, the Cisco IOS software lowers the DTR signal, which disconnects the modem. This command is useful for older modems that do not support autoanswer.
This command uses clear to send (CTS), whereas other modem commands in the Cisco IOS software use data set ready (DSR).
Only use the modem callin command on the ASM terminal server, where hardware flow control is not possible. If you have a Cisco 2500 or 3600 series router, use the modem dialin command instead.
Examples
The following example configures lines 10 through 16 for dial-in modems that can run at speeds from 300 to 19,200 bits per second:
line 10 16

This command was introduced. |
Usage Guidelines
This command supports ports connected to computers that would normally be connected to modems. It causes the access server to act somewhat like a modem.
This command uses the clear to send (CTS) signal and should be used only on access servers that do not support hardware flow control. If you have an access server that is newer than the ASM terminal server (such as a Cisco 2500 or Cisco 3600 series routers, or a Cisco AS5100 or Cisco AS5200 access servers), use the modem host command instead. The modem callout command uses CTS, whereas the modem host command uses data set ready/ data carrier detect (DSR/DCD.) If CTS is used for modem control instead of DSR/DCD, it prevents CTS from being used by hardware flow control.
Examples
The following example configures lines 17 through 32 in reverse connection mode to a large terminal switch. By using Telnet to connect to a TCP port on this host, the user gets the next free line in the rotary group.

Usage Guidelines
The modem management subsytem provides event logs for each modem at each major event during usage of the modems. The volume of event logs being generated makes the monitoring of modem calls for debugging purposes difficult. The MCR log, activated using the modem call-record command, will log a summary of a modem call to syslog upon termination of the call. If a call fails to establish a connection, the call will be summarized in a Modem Call Failed Record.
The MCR is written to the syslog and can be displayed using the terminal monitor or show logging command, or by examining files on a syslog server.
The modem call-record command is supported on Cisco AS5200, AS5300, AS5800, 2600, and 3600 routers with integrated MICA technologies and Microcom modems. For systems with NextPort modems, use the spe call-record modem command.
The information provided in the MCR log and the Modem Call Failed Record log varies depending on the type of modem being used. Table 2 describes the significant fields in the display for MICA technologies and Microcom modems.

12.2(4)T |
The delay keyword was added to support the Cisco modem user interface. |
Usage Guidelines
This command supports modems that can automatically handle telephone line activity, such as answering the telephone after a certain number of rings.
The delay keyword is useful when using the modemui EXEC command with software that requires a signal assertion to recognize that a connection has been established. It may be necessary to reroute the router DTR signal to an alternate EIA-232 pin such as Carrier Detect (CD) for the delay to work properly.
Examples
The following example configures a line for a high-speed modem:
The following example shows how to set up a delay in a line configured for the Cisco modem user interface feature:

|
12.2(8)YN |
This command was introduced. |
12.2(13)ZG |
The optional autodetect keyword was added to this command for Cisco 831, 836, and 837, and Cisco SOHO 91 and 97 routers. |
12.3(2)T |
This command was integrated into Cisco IOS Release 12.3(2)T. |
Usage Guidelines
On the Cisco 831, 836, and 837, and SOHO 91 and 97 routers, the console port and the auxiliary port share the same physical RJ-45 port. The console port must be changed to act as a virtual auxiliary port using the modem enable [ autodetect ] command before the dial backup and remote management capabilities can be enabled.
Use the show line autodetect EXEC command to determine when a modem or a console has been detected. This command displays the following messages to indicate the type or state of connection on the console line:
- Detection State: Console Attached—A DTE console or terminal device is attached.
- Detection State: Modem Attached—A DCE asynchronous modem device is attached.
- Detection State: Nothing Attached—No cable is attached to the EIA/TIA--232 port on the router.
- Detection State: Init State—Autodetection has been enabled, but no changes have been detected.
- Detection State: Feature not enabled—No device connection is detected.
Note
The auto detection capability on the Cisco 831, 836, and 837 routers that detects whether a modem or console is attached to its RJ-45 console port will not work when the router is booting up. The routers use the data set ready (DSR) and clear to send (CTS) pin statuses to detect whether a modem or console is attached.
Examples
The following example enables the line autodetect option:
Router(config-line)# modem enable autodetect
Use the show line autodetect command to determine when a modem or a console has been detected:
Router# show line autodetect
Detection State: Nothing Attached
Router# show line autodetect
Detection State: Console Attached

This command was introduced. |
Usage Guidelines
The modem hold-reset command for the V.110 port module resets the processor on board the module only if the command is executed on all 12 ports. If the modem hold-reset command is issued on only a portion of the V.110 ports, the processor will not reset.
This command is also used to reset a modem that is frozen in a suspended state. Disable the suspended modem with the modem hold-reset command, and then restart initialization with the no modem hold-reset command.
Examples
The following example disables the suspended modem using tty line 4 and resets the modem’s initialization:
The following examples resets a 12-port V.110 port module. You must specify the entire tty line range for the entire bank of ports.

Usage Guidelines
This command supports ports connected to computers that would normally be connected to modems. This command causes the access server to act like a modem.
The modem host command is identical in operation to the modem callout command except that data set ready/data carrier detect (DSR/DCD) is used for modem control instead of clear to send (CTS). This frees CTS for use by hardware flow control.
Examples
The following example configures a line to send a DSR/DCD active signal to the modem for data switches and hosts:
