Field	Description
s - static	The channel is in an out-of-service state because of a busyout command.
d - dynamic	The channel is automatically put in an out-of-service state because of a preset and defined threshold. By default, this feature is disabled. This autobusyout function of the modem busyout-threshold global configuration command is used to define a threshold when you want to maintain a balance between the number of DS0s and modems.
p - pending	After you hang up, the established call is terminated because of a busyout command. After the call terminates, the DS0 is busied out.

Related Commands

Command	Description
busyout	Informs the central-office switch that a channel is out of service.
ds0 busyout (channel)	Forces a DS0 time slot on a controller into the busyout state.
modem busyout	Disables a modem from dialing or answering calls whereby the disabling action is not executed until the active modem returns to an idle state.
modem busyout-threshold	Maintains a balance between the number of DS0s and modems.
modem shutdown	Abruptly shuts down an active or idle modem installed in an access server or router.

(Optional) Displays Call Tracker data for a specific type of call. The default is to show all calls, regardless of type. By specifying the category keyword with one of the optional modem type keywords (isdn, modem, other, v110, v120), Call Tracker shows only those calls whose records indicate that category.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.1(3)T	This command was introduced.

Usage Guidelines

This command allows you to display call activity for a single supported call category type, if desired, by using the category keyword with one of the optional keywords.

Examples

The following example shows Call Tracker activity for modem calls:

show call calltracker handle

To display all information stored within the Call Tracker active or history database table for a specified unique call handle identifier, use the show call calltracker handle command in privileged EXEC mode.

show call calltracker handle call-identifier

Syntax Description

call-identifier

Unique call identifier (handle) assigned by Call Tracker from the moment a DS0 B channel is requested. This identifier is a sequential number starting with handle 1.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.1(3)T	This command was introduced.

Usage Guidelines

Each call managed by Call Tracker is assigned a unique call handle that is provided to users using the Simple Network Management Protocol (SNMP), the command line interface, or SYSLOG for all forms of data transfers. Knowing this call handle makes it easier to display the information desired for a given call than to manually search through all Call Tracker database tables for latest updates.

Examples

The following is sample output from the show call calltracker handle command:

Router# show call calltracker handle 30

-------------------------- call handle=0000000030 --------------------------

Table 27 describes the significant fields shown in the display.

Table 27 show show call progress tone Field Descriptions

Field	Description
Cadence number	Call progress tones consist of cadences—periods of sound or silence with certain parameters that do not change during the call. The cadence number shows the number of a particular cadence within the CP tone definitions. Cadence numbers start at 0.
Cadence duration	Cadence duration. "Forever" means that the sound can be heard forever, like in a dialtone.
Cadence type	Silence—No tone is generated. 440Hz—A single frequency is generated. 440x530Hz—Two frequencies are added (mixed).
Amplitudes for corresponding frequency components	Amplitudes for the corresponding frequency components. Different amplitudes are used on different trunk types.

Related Commands

Command	Description
call progress tone country	Specifies the country code for retrieving the call progress tone parameters from the CP tone database.

show caller

To display caller information, enter the show caller command in EXEC mode.

show caller [{full | {interface {Async | Dialer | Serial}} | line {range | line-modem-options} | summary | timeouts | user name [detailed]}]

Syntax Description

full	(Optional) Provides expanded caller information.
interface	(Optional) Displays a summary of caller information for the interface name you provide: Async—Async interface number in the range from 1 to 169. Dialer—Dialer interface number in the range from 0 to 799. Serial—Serial interface number in the range from 0 to 3.
line {range | line-modem-options}	(Optional) Displays a summary of caller information for the lines you specify, in the range from 0 to 54, or by line or modem options, as follows: aux—Auxiliary line. console—Primary terminal line. tty—Terminal controller. v110—V.110 modem standard information. vty—Virtual terminal line. x/y—Internal modem slot/port.
summary	(Optional) Displays total users logged and total ISDN or analog users since the last reload command was entered.
timeouts	(Optional) Displays session and idle limits and disconnect time.
user name	(Optional) Displays a summary of caller information for the username you provide.
detailed	(Optional) Provides expanded information about the username specified.

Defaults

No default behavior or values.

Command Modes

EXEC

Command History

Release	Modification
11.3(5)AA	This command was introduced.
12.1(3)T	The summary keyword was added.

Usage Guidelines

The show caller command is used to:

•Display individual users and consumed resources on the network access server (NAS).

•Inspect active call statistics for large pools of connections. (Debugging commands produce too much output and tax the CPU too heavily.)

•Display the absolute and idle times for each user. The current values for both of these settings are displayed on the TTY line and the asynchronous interface. Users that have been idle for unacceptably long periods of time can be easily identified. By using this information, you can define timeout policies and multiple grades of services for different users.

You can configure output modifiers for each option type of the show caller command.

Examples

The following is sample output from the show caller command:

Router# show caller

  Line      User                  Service       Active   

  con 0     -                     TTY           00:08:21

  BR0:1     hatteras              PPP           00:00:14

  Vi1       hatteras              PPP   Bundle  00:00:13

The following is sample output from the show caller command with the summary keyword:

Router# show caller summary

      933   Analog calls

        0   ISDN calls

      933   Total users logged in

  1305767   Total users since last reload

Each display from the show caller command is self explanatory; see the "Usage Guidelines" section for more information.

show controllers bri

To display information about the ISDN BRI, use the show controllers bri command in privileged EXEC mode.

Cisco MC3810 Routers

show controllers bri [interface-number]

Cisco 7200 Series Routers

show controllers bri slot/port

All Other Routers

show controllers bri number

Syntax Description

interface-number	Interface number. The value is from 0 to 7 if the router has one 8-port BRI network interface module (NIM), or from 0 to 15 if the router has two 8-port BRI NIMs. Interface number values will vary, depending on the hardware platform used. The Cisco 3600 series router, for example, can have up to 48 interfaces. Valid BRI controller numbers for the Cisco MC3810 router are from 1 to 4.
slot/port	Backplane slot number and port number on the interface. See your hardware installation manual for the specific slot and port numbers. The slash mark is required.

Command Modes

Privileged EXEC

Command History

Release	Modification
10.3	This command was introduced.
11.2 P	This command was enhanced to support slot and port syntax for the PA-8B-ST and PA-4B-U port adapters on the Cisco 7200 series.
12.0(3)XG	This command was implemented on the Cisco MC3810 universal access concentrator.

Usage Guidelines

If you use the show controllers bri command in the Cisco MC3810 without the slot-number keywords, information for all of the configured ISDN BRI controllers will be displayed. The BRI controller numbers match the physical ports numbers on the BRI voice module (BVM).

Examples

The following example shows controller statistics for interface BRI 1 on a Cisco MC3810 router:

Command Modes

EXEC

Command History

Release	Modification
10.0	This command was introduced.

Usage Guidelines

If you enter the show dialer interface command for the D channel of an ISDN BRI or PRI, the command output also displays the B channels. That is, the show dialer interface bri 0 command displays information of interfaces bri 0, bri 0:1, and bri 0:2. The show dialer interface serial 0:23 command (for a channelized T1 line configured for ISDN PRI) displays information for serial interfaces 0:23, 0:0, 0:1, and so forth to 0:22.

If you have defined a dialer group that consists of the interfaces serial 0, serial 1, and bri 2, the show dialer interface dialer 1 command displays information for interfaces bri 0, bri 0:1, bri 0:2, serial 1, and serial 0.

Examples

The following is sample output from the show dialer command for a BRI interface when dialer profiles are configured:

Router# show dialer interface bri 0

BRI0 - dialer type = ISDN

Dial String      Successes   Failures    Last called   Last status

0 incoming call(s) have been screened.

BRI0: B-Channel 1

Table 38 describes the significant fields shown in the display.

Table 38 show dialer interface bri Field Descriptions 

Field	Description
BRI0 - dialer type = ISDN	ISDN dialer.
Dial String	Dial strings of logged calls (telephone numbers). On ISDN BRI interfaces, if you have specified a subaddress number in the dialer string, this number is included in the dial string after a colon.
Successes	Successful connections (even if no data is passed).
Failures	Failed connections; call not successfully completed.
Last called	Time that last call occurred to specific dial string.
Last status	Status of last call to specific dial string (successful or failed).
0 incoming call(s) have been screened.	Number of calls subjected to Dialer Profiles screening to determine how the call is to be treated.

Idle timer (120 secs), Fast idle timer (20 secs)	Settings (in seconds) for the idle timer and the fast idle timer.
Wait for carrier (30 secs), Re-enable (15 secs)	Settings (in seconds) for the wait for carrier timer and the reenable timer.
Dialer state is data link layer up	The message "data link layer up" suggests that the dialer came up properly; if it says anything else then dialer did not come up properly. The message "physical layer up" means the Line Control Protocol (LCP) came up, but the Network control Protocol (NCP) did not come up. The show interfaces command also provides similar information.
Dial reason: ip (s=10.1.1.8, d=10.1.1.1)	What initiated the dial, namely an IP packet, plus source and destination address in the packet.
Interface bound to profile Dialer0	Dialer profile that is bound to this interface or B channel.
Time until disconnect	Time, in seconds, until line is configured to disconnect.
Current call connected	Time, in hours: minutes: seconds, at which the current call was connected.
Connected to	Dial string to which the line is currently connected.

The following is sample output from the show dialer command for an asynchronous interface:

Router# show dialer interface async 1

Async1 - dialer type = IN-BAND NO-PARITY

Idle timer (900 secs), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

When the show dialer EXEC command is issued for a synchronous serial interface configured for data terminal ready (DTR) dialing, output similar to the following is displayed:

Router# show dialer interface serial 0

Serial 0 - dialer type = DTR SYNC

Idle timer (120 secs), Fst idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

 Dial String   Successes   Failures    Last called   Last status

Table 40 describes additional fields shown in the display; see Table 39 for information about the other fields in the report.

Table 40 show dialer Field Descriptions for DTR Dialers

Field	Description
DTR SYNC	Indicates that DDR is enabled and that DTR dialing is enabled on this synchronous interface.
Last status: Success	Indicates that the last call was successful and that DTR dialing was used.
DTR dialer	Phrase appended to the Last status entry to indicate that this is a DTR dialer.

If an interface is connected to a destination, a display is provided that indicates the idle time before the line is disconnected. (The value decrements each second.) Then the duration of the current connection is displayed. The following is an example of this display:

Time until disconnect 596 secs

Current call connected 0:00:25

After a call disconnects, the system displays the time remaining before it can be dialed again. The following is an example of this display:

Time until interface enabled 8 secs

If the show dialer command is issued for an interface on which DDR is not enabled, the system displays an error message. The following is a sample error message:

Async 1 - Dialing not enabled on this interface.

If an interface is configured for DDR, the show interfaces command displays the following message:

Async1 is up, line protocol is up (spoofing)

Hardware is Async Serial

The word spoofing indicates that the line really is not up, but the dialer is forcing the line to masquerade as "up" so that upper level protocols will continue to operate as expected. Spoofing is a state added to allow DDR to work. The interface "dials on demand" in response to packets being routed to it. But because no packets are routed to down interfaces, the interface must pretend to be up (spoof) so packets will be routed to it when it is not connected. Spoofing is the normal idle state on a dial-on-demand interface.

If caller ID screening is configured on an ISDN BRI, the show dialer command display includes a line similar to the following:

1 incoming call(s) have been screened.

This line reports the number of calls that have been screened.

show dialer dnis

To see how many calls Dialed Number Information Service (DNIS) groups have had, use the show dialer dnis command in privileged EXEC mode.

show dialer dnis {group [name] | number [number]}

12.0(4)XI	This command was introduced.

Usage Guidelines

If no DNIS groups are configured and resource pooling is enabled, then no calls are accepted. All calls are identified by call type/DNIS combinations.

Use the show dialer dnis EXEC command to display how many calls DNIS groups have had or how many calls a specific DNIS group has had. You can configure each DNIS group with multiple numbers. Using this command displays tables of statistics for each DNIS number received at the network access server.

Examples

The following example shows the show dialer dnis command being used to display DNIS group and DNIS number statistics:

Router# show dialer dnis ?

  group   DNIS group statistics

  number  DNIS number statistics

Router# show dialer dnis group

Command History

Release	Modification
9.21	This command was introduced.

Usage Guidelines

If you enter the show dialer interface bri command for the D channel of an ISDN BRI, the command output also displays the B channels. That is, the show dialer interface bri 0 command displays information of interfaces bri 0, bri 0:1, and bri 0:2. Similarly, use of the related show dialer interface serial 0:23 command (for a channelized T1 line configured for ISDN PRI) displays information for serial interfaces 0:23, 0:0, 0:1, and so forth to 0:22.

If you have defined a dialer group that consists of the interfaces serial 0, serial 1, and bri 2, the show dialer interface dialer 1 command displays information for interfaces bri 0, bri 0:1, bri 0:2, serial 1, and serial 0.

Examples

The following example shows the show dialer interface bri command report for a BRI interface when dialer profiles are configured:

Router# show dialer interface bri 0

BRI0 - dialer type = ISDN

Dial String      Successes   Failures    Last called   Last status

0 incoming call(s) have been screened.

BRI0: B-Channel 1

Idle timer (120 secs), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is data link layer up

Dial reason: ip (s=10.1.1.8, d=10.1.1.1)

Interface bound to profile Dialer0

Time until disconnect 102 secs

Current call connected 00:00:19

Connected to 5551212 (Device1)

BRI0: B-Channel 2

Idle timer (120 secs), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is idle

Table 42 describes the significant fields shown in the display.

Table 42 show dialer interface bri Field Descriptions 

Field	Description
BRI0 - dialer type = ISDN	ISDN dialer.
Dial string	Dial strings of logged calls (telephone numbers). On ISDN BRI interfaces, if you have specified a subaddress number in the dialer string, this number is included in the dial string after a colon.
Successes	Successful connections (even if no data is passed).
Failures	Failed connections; call not successfully completed.
Last called	Time that last call occurred to specific dial string.
Last status	Status of last call to specific dial string (successful or failed).
0 incoming call(s) have been screened.	Number of calls subjected to Dialer Profiles screening to determine how the call is to be treated.
BRI0: B-Channel 1	Header indicating the following data is for B channel 1.
Idle timer (120 secs), Fast idle timer (20 secs)	Settings (in seconds) for the idle timer and the fast idle timer.
Wait for carrier (30 secs), Reenable (15 secs)	Settings (in seconds) for the wait for carrier timer and the reenable timer.
Dialer state is data link layer up	The message "data link layer up" suggests that the dialer came up properly; if it says anything else then dialer did not come up properly. The message "physical layer up" means the line protocol (LCP) came up, but the NCP did not come up. The show interfaces command also provides the similar information.
Dial reason: ip (s=6.1.1.8, d=6.1.1.1)	What initiated the dial, namely an IP packet, plus source and destination address in the packet.
Interface bound to profile Dialer0	Dialer profile that is bound to this interface or B channel.
Time until disconnect	Time until line is configured to disconnect. This field is displayed if the interface is currently connected to a destination.
Current call connected	Time at which the current call was connected.
Connected to	Dial string to which line is currently connected.

If an interface is connected to a destination, a display is provided that indicates the idle time before the line is disconnected. (The value decrements each second.) Then the duration of the current connection is shown. The following shows an example of this display:

Time until disconnect 596 secs

Current call connected 0:00:25

After a call disconnects, the system displays the time remaining before being it can dial again. The following is an example of this display:

Time until interface enabled 8 secs

If caller ID screening is configured on an ISDN BRI, the show dialer interface bri command display includes a line similar to the following:

1 incoming call(s) have been screened.

This line reports the number of calls that have been screened.

show dialer map

To display configured dynamic and static dialer maps and dynamically created PPP Bandwidth Allocation Control Protocol (BACP temporary static dialer maps, use the show dialer map command in EXEC mode.

show dialer map

Syntax Description

This command has no arguments or keywords.

Command Modes

EXEC

Command History

Release	Modification
11.2	This command was introduced.

Examples

The following is sample output from the show dialer map command. The dialer maps are grouped by network address. When multiple dialer maps exist for the same network address, the dialer maps differ only by phone number. In this output, the dialer maps marked "BAP" are temporary dialer maps the PPP BACP creates when a peer calls from a different phone number than is configured or when a peer calls from a number that does not appear in an existing map. The temporary dialer maps allows PPP BACP to make outgoing calls to the peers.

Router# show dialer map

Static dialer map ip 10.1.1.1 name peer_1 on Dialer1

Static dialer map ip 10.1.1.2 name peer_2 on Dialer1

BAP dialer map ip 10.1.1.2 name peer_2 on Dialer1

Dynamic dialer map ip 10.1.1.3 name peer_3 on Dialer1

BAP dialer map ip 10.1.1.3 name peer_3 on Dialer1

Table 43 describes the significant fields shown in the display.

Table 43 show dialer map Field Descriptions 

Field	Description
Static dialer map ip 10.1.1.1	A configured static dialer map to call the specified protocol address.
name peer_1	Name of the remote peer.
on Dialer1	The physical or logical dialer interface on which the static map is configured.
BAP dialer map ip 10.1.1.2	A temporary dialer map that was created by PPP BACP for the particular destination with a different phone number from that of any existing maps. It will be removed when the BACP group is removed or the last remaining map to that destination is removed.
Dynamic dialer map ip 10.1.1.3	Dialer map dynamically created when a peer called.
BAP dialer map ip 10.1.1.3 name peer_3	Temporary static dialer map created by PPP BACP when required. It will be removed when the BACP group is removed or when the dynamic dialer map disappears.

When the router is in dial shelf split mode, the show dial-shelf command indicates that the router shelf is running in split mode and which slots the router shelf owns. The status of any cards in any owned slots will be displayed just as they are in the present command. Thus when in normal mode, this command is unchanged from the original version.

When in split mode, the output will be extended, as in the following example:

Router# show dial-shelf
