Table 66 show modem Field Descriptions 

Field
Description

Mdm

Slot and modem port number. Also, the following modem states can appear to the left of a slot/modem port number:

•b—Modem was removed from service with the modem shutdown command or the modem busyout command.

•B—Modem is suspected to be inoperable or bad. No calls can be made with this modem. The letter B can also mean that a modem firmware download failed for the specified modem. In this case, try unmarking the modem as bad with the no modem bad command and upgrading the modem firmware again.

•d—The RAM-based Digital Signal Processor (DSP) code, which supports K56flex, is not configured. The modem will revert to transmitting at 33.6 kbps.

•D—Modem is downloading firmware.

•p—Firmware download is pending, typically because one or more modems is active.

•R—Modem is held and isolated in a suspended state by the modem hold-reset command.

•T—Modem is conducting a back-to-back test with another modem.

•*—Modem is connected or dialing.

Usage

Percentage of the total system uptime that all modems are in use.

Inc calls

Number of incoming calls that successfully and unsuccessfully connected to a modem.

Out calls

Number of outgoing calls that successfully and unsuccessfully dialed out from an available modem.

Busied Out

Number of modems that have been manually removed from service.

Failed Dial

Number of modems that attempted to dial in to the network but failed to make a connection.

No Answer

Number of modems that detected an incoming ring but failed to answer the call.

Succ Pct.

Successful connection percentage of total available modems.

The type of display output generated from the show modem slot/port command depends on the version of Cisco IOS software running on the router or access server. For example, the following shows example output for a 56K modem card, which carries digital modems that transmit at 56 kbps. (In truth, 56K modems do not modulate or demodulate data. A pure digital-to-digital connection is made.) See Table 67 for a description of the fields displayed by this modem card.

Connection Speeds
# of connections

A complete summary of possible connection speeds and the actual number of connections that occurred at those speeds. Depending on which modem port module and version of software you are running, possible connection speeds range from 75 to 56000 bits per second (bps). The number of successful connections is displayed directly beneath the connection speed identifier. For example, the following output shows that three connections were made at 56 kbps:

Connection Speeds 56000
# of connections 3


The following example shows the output for modem group 1, which comprises modem 1/0 through modem 1/23. The report is self explanatory.

Modification

11.3

This command was introduced.

12.2(11)YT

This command was enhanced to display information about digital modems on the Cisco 3600 and 3700 series routers that support the V.92 and V.44 standards.

12.2(15)T

This enhanced command was integrated into Cisco IOS Release 12.2(15)T.


Usage Guidelines

Use this command to find out why a modem ended its connection or why a modem is not operating at peak performance.

Local disconnect reasons for a particular modem are listed across the top of the screen display. For example, see lostCarr, dtrDrop, rmtLink, wdogTimr, compress, retrain, inacTout, and linkFail in the following output: 

Router# show modem call-stats


  dial-in/dial-out call statistics


       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail

  Mdm 

* 0/0 

* 0/1

In the body of the screen display, the number of times an error occurred on a specific modem is displayed (see the # column). The % column shows the total running percent that a modem was logged for the specified disconnect reason with respect to the entire modem pool. For example, out of all the times that the lostCarr error occurred on all the modems in the system, the lostCarr error occurred 2 percent of the time on modem 0/0. 

Router# show modem call-stats


  dial-in/dial-out call statistics


       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail

  Mdm     #   %    #   %    #   %    #   %    #   %    #   %    #   %    #   %

* 0/0     6   2    2   3    1   0    0   0    0   0    0   0    0   0    0   0

* 0/1     5   2    2   3    2   1    0   0    0   0    0   0    0   0    0   0

Bad or malfunctioning modems are detected by an unusually high number of disconnect counters for a particular disconnect reason. For example, if modem 1/0 had a high number of compression errors compared to the remaining modems in system, modem 1/0 would probably be bad or inoperable.

To reset the counters displayed by the show modem call-stats command, use the clear modem counters command.

Note Remote disconnect reasons are not described by this command.

Examples

The following example shows call statistics for the show modem call-stats command. Because of the screen size limitation of most terminal screen displays, all the possible disconnect reasons cannot be displayed at the same time. Only the top eight most frequently experienced disconnect reasons are displayed.

The number of times that a modem is disconnected because Modem on Hold (MOH) terminates. MOH will terminate for two reasons:

•MOH clear down by the modem (MICA_DR_MOH_CLEAR_DOWN)

•MOH time out (MICA_DR_MOH_TIMEOUT)

wdogTimr

Watchdog timeout. An obscure firmware problem occurred. This is a rare disconnect reason.

compress

Compression. An error was detected during decompression, which caused the internal decompression dictionary to overflow. This could be caused by a modem dialing in that is using a slightly different compression algorithm.

retrain

Retrain failure. A connection was lost and not reestablished after three attempts.

inacTout

Inactivity timeout. The time specified in the AT/T command has expired. No modem data transfers were detected during that period.

linkFail

Link failure. The protocol level link failed while using MNP-10 or LAPM (Link Access Procedure for Modems) in reliable mode.

moduFail

Modulation error. An error was detected at the Digital Signal Processor (DSP) chip level, which caused a disconnect.

mnpProto

MNP10 protocol error. An uncorrectable error occurred during an MNP-10 connection.

lapmProt

LAPM protocol error. An uncorrectable error occurred during a LAPM connection.

lostCarr

Lost carrier. The modem firmware detected a carrier drop during a connection. The cause for the carrier drop could be the loss of signal from the remote modem or the result of a error detection.

dtrDrop

DTR drop. The modem disconnected because the DTR signal from the host became inactive.

userHgup

User hang-up. The modem disconnected because a command such as ATH was detected.

rmtlink

Remote link disconnect. If an MNP-10 reliable link is established, the remote modem sends the disconnect reason across the link before disconnecting. The disconnect reason displayed is LOCAL (remote link disconnect) and REMOTE (the reason the remote modem disconnected).

trminate

Terminate. A password security error occurred in the Microcom High Density Management System (HDMS). This error occurs only with Microcom modems.

callBkfa

Callback failed. This error applies to leased line connections only. A switched line connection failed and a connection still cannot be made on the leased line.

dial-out call statistics

This category of disconnect reasons can happen only in a dial-out scenario.

noCarr

No carrier. The called number answered, but no answer tone was detected after the appropriate wait.

noDitone

No dial tone. No dial tone was detected after the modem went off hook.

busy

Busy. A busy signal was detected while the local modem was attempting to dial.

abort

Abort. A character was received from the remote host after the dial command was issued and before a connection was established.

dialStrg

Dial string error. An invalid character was detected in the dial string, which forced the dial attempt to terminate.

autoLgon

Autologon error. An autologon sequence did not successfully complete.

dialTout

Dial timeout. When a semicolon is used as a dial modifier, the modem returns to the command state as indicated by an "OK." This character allows a continuation of the dial string. If a period of time elapses as specified in the S7 register without the dial string completing, the attempt is aborted with dial timeout as the disconnect reason.

rmtHgup

Remote hang-up. The modem disconnected because the remote modem disconnected the call and dropped DTR.

blacklst

Blacklist. In a country that supports blacklisting, an attempt was made to go off hook with a null dial string (ATD).

ccpNssn

CCP not seen. The credit card prompt (also known as Bong) was not detected.

faxClasz

Fax class 2 error. An abnormal termination to a fax transmission was detected.

Total

Total number of times the disconnect reason occurred among all the modems in the system.


show modem calltracker

To display all information stored within the Call Tracker active or history database for the latest call assigned to a specified modem, use the show modem calltracker command in privileged EXEC mode.

show modem calltracker [slot/port]

Syntax Description

slot/port

(Optional) Location of a slot and modem port. Remember to include the slash mark when entering this argument.


Command Modes

Privileged EXEC

Command History

Release
Modification

12.1(3)T

This command was introduced.


Usage Guidelines

This command allows you to display all Call Tracker data for a given modem when you do not have the call handle readily available and do not want to search the Call Tracker database.
