call progress tone country

To specify the country code for retrieving the call progress tone parameters from the call progress tone database, use the call progress tone country command in configuration mode. Use the no version of this command to cancel the previous setting and to generate the call progress tones according to modem settings.

call progress tone country country-name

no call progress tone country country-name

Syntax Description

country-name

Selects default call progress tones (ring and cadence settings) for the specified country. Valid entries are: argentina, australia, austria, belgium, brazil, canada, china, colombia, cyprus, czech-republic, denmark, finland, france, germany, greece, hongkong, hungary, iceland, india, indonesia, ireland, israel, italy, japan, korea, luxembourg, malaysia, mexico, netherlands, peru, philippines, poland, portugal, russia, singapore, slovakia, slovenia, south-africa, spain, sweden, switzerland, taiwan, thailand, turkey, unitedkingdom, usa, and venezuela.

Defaults

Modem default settings. (The country-name keyword northamerica was the default in Cisco IOS Release versions earlier than release 12.0(3)XG; usa is the default country keyword for Cisco IOS Release 12.0(3)XG and later releases.)

Command Modes

Configuration mode

Command History

Release	Modification
12.0(3)XG	This command was introduced.
12.0(4)XI	This command was enhanced with additional and different country keywords.

Usage Guidelines

Use the call progress tone configuration to specify the country for call progress tone generation. While in many cases the country is chosen automatically based on the modem setting, automatic selection won't work for all users because many modems do not support all countries and many users choose the "us" or "default-t1" or "default-e1" setting on their modem.

This command affects the tones generated at the local interface and does not affect any information passed to the remote end of a connection or any tones generated at the remote end of a connection.

For dial platforms (AS5200, AS5300, and AS5800), call progress tones are used only for the resource pool management application. Resource pool management assumes that the call progress tone selection is global. Select only one call progress tone set for the whole box, and it will globally override country settings on all ports.

Examples

The following example shows the call progress tone set for Japan tone parameters:

call progress tone country japan

Related Commands

Command	Description
show call progress	Displays the contents of the internal CP tone database for a specific country.

callback forced-wait

To force the Cisco IOS software to wait before initiating a callback to a requesting client, use the callback forced-wait command in global configuration mode. Use the no form of this command to disable the forced waiting period.

callback forced-wait

no callback forced-wait

Syntax Description

This command has no arguments or keywords.

Defaults

The forced waiting period is not set.

Command Modes

Global configuration

Command History

Release	Modification
11.1	This command was introduced.

Usage Guidelines

Use this command when the router is calling back a modem that initiated a call, then dropped the connection, but requires a rest period before subsequent input is accepted.

Examples

The following example sets a waiting period during which a callback chat script is delayed from being sent on an outgoing target line:

callback-forced-wait 

Related Commands

Command	Description
arap callback	Enables an ARA client to request a callback from an ARA client.
chat-script	Places calls over a modem and logs in to remote systems.
debug callback	Displays callback events when the router is using a modem and a chat script to call back on a terminal line.
ppp callback (DDR)	Enables a dialer interface that is not a DTR interface to function either as a callback client that requests callback or as a callback server that accepts callback requests.
server (RLM)	Enables the Cisco IOS software to call back clients that request a callback from the EXEC level.
virtual-profile aaa	Enables virtual profiles by AAA configuration.

callback nodsr-wait

To set the time period for which an asynchronous callback waits to see the DSR signal go low after the router signals a hang-up request on the incoming call, use the callback nodsr-wait command in line configuration mode. To negate or change the line setting, use the no form of this command.

callback nodsr-wait milliseconds

no callback nodsr-wait

Syntax Description

milliseconds

The timeout value in a range from 5000 to 30,000 milliseconds (ms). Default is 5000 ms.

Defaults

5000 ms

Command Modes

Line configuration

Command History

Release	Modification
11.2(6.1)P	This command was introduced.

Usage Guidelines

Use the callback nodsr-wait command when the dial-out modem takes longer than 5000 ms to drop a carrier after the router signals a hang-up on the incoming call.

Increase the duration of the callback if the debug callback command displays the following failed callback attempt message:

callback process fail - timeout with DSR up

Examples

The following example sets the callback duration to 10 seconds for lines 1/0 to 1/107:

line 1/0 1/107 

callback nodsr-wait 10000

Related Commands

Command	Description
callback forced-wait	Sets a waiting period when DSR signals decrease after a callback, before the router attempts another callback.
debug callback	Displays callback events when the router is using a modem and a chat script to call back on a terminal line.

called-number

To assign a called party number to a pool of modems, use the called-number command in modem pool configuration mode. Use the no form of this command to remove a number from a modem pool.

called-number number [max-conn number]

no called-number number [max-conn number]

Syntax Description

number	Called number for a modem pool.
max-conn number	(Optional) Maximum number of simultaneous connections allowed for the called party number.

Defaults

Disabled

Command Modes

Modem pool configuration

Command History

Release	Modification
11.2P	This command was introduced.

Usage Guidelines

A called party number is a telephone number that is used to reach a remote destination. For example, a mobile laptop dials a called party number to reach an ISP's POP. Some ISPs set up several called party numbers to enable remote clients to dial in, but to the end user, it appears and functions as one unified service.

Cisco's implementation of a called party number is based on the dialed number identification service (DNIS). You can configure multiple DNIS numbers in a single modem pool. However, the same DNIS number cannot be used in multiple modem pools. Each modem pool must be assigned different DNIS numbers.

Use the max-conn option to provide overflow protection, which specifies a maximum number of simultaneous connections that a called party number can consume. For example, if you create one modem pool to serve two or more services or customers, this option guarantees how many modems each service or customer can have access to at any given time.

The Cisco IOS software also includes a feature that simplifies the called number configuration. By using an x variable as the last digit in a called telephone number (for example, issuing the called-number 408555121x command), clients dialing different called numbers such as 4085551214 or 4085551215 will automatically be sent to the same modem pool. The x variable is a floating place holder for digits 1 through 9.

---

Note Modem pools using MICA technologies or Microcom modems support incoming analog calls over ISDN PRI. However, only MICA modems support modem pooling for CT1 and CE1 configurations with channel associated signalling.

---

Examples

In the following example, the modem pool called v90service is virtually partitioned between two customers using different DNIS numbers. The pool-range command assigns modems 1 to 110 to the shared modem pool. The called-number 5551212 max-conn 55 command assigns the DNIS number 5551212 to the v90service modem pool. The total number of simultaneous connections is limited to 55. The called-number 4441212 max-conn 55 command assigns the DNIS number 4441212, which is for a different customer, to the same v90service modem pool. The total number of simultaneous connections is also set to 55.

modem-pool v90service

 pool-range 1-110

 called-number 5551212 max-conn 55

 called-number 4441212 max-conn 55

The following configuration rejects the pool-range 30 command because modem TTY line 30 is already a member of the modem pool v90service, which was configured in the previous example. Each modem in the access server is automatically assigned to a unique TTY line. TTY line numbers are assigned according to your shelf, slot, or port hardware configuration.

modem-pool v34service

# pool-range 30

Related Commands

Command	Description
clear modempool-counters	Clears active or running counters associated with one or more modem pools.
modem-pool	Creates a new modem pool or specifies an existing modem pool, which allows you to physically or virtually partition your access server for dial-in and dial-out access.
pool-member	Assigns a range of modems to a modem pool.
show modem-pool	Displays the configuration and connection status for one or more modem pools.

call-type

To reject particular types of calls, use the call-type command in call discriminator profile configuration mode, use the no form of this command to disable this feature.

call-type {all | digital | speech | v110 | v120}

no call-type {all | digital | speech | v110 | v120}

Syntax Description

all	Rejects all calls.
digital	Rejects digital calls.
speech	Rejects speech calls.
v110	Rejects V.110 calls.
v120	Rejects V.120 calls.

Defaults

All calls are accepted by the network access server.

Command Modes

Call discriminator profile configuration

Command History

Release	Modification
12.0(4)XI	This command was introduced.

Usage Guidelines

Use the call-type call discriminator command to reject particular types of calls. Call type "all" is mutually exclusive for all other call types. If call type "all" is set in the discriminator, no other call types are allowed. Also, once a DNIS is associated with a call type in a discriminator, it cannot be used in any other discriminator.

Examples

The following example shows the call discriminator being configured to reject speech calls for the call discriminator profile named userd3:

resource-pool profile discriminator userd3

 call-type speech

call-type cas

To statically set the call-type override for incoming channel-associated signalling (CAS) calls, use the call-type cas command in DNIS group configuration mode. Use the no form of this command to disable this service.

call-type cas {digital | speech}

no call-type cas {digital | speech}

Syntax Description

digital	Override call type to digital. The incoming call with the DNIS in the called group is treated as a digital call type.
speech	Override call-type to speech. The incoming call with the DNIS in the called group is treated as a speech call type.

Defaults

No default behavior or values.

Command Modes

DNIS group configuration

Command History

Release	Modification
12.0(4)XI	This command was introduced.

Usage Guidelines

Use the call-type cas DNIS group configuration command to set the call-type override. From the resource pooling call-type perspective, use CT1 (CAS) to support either analog calls (speech) or digital calls (switched 56K).

Switched 56K calls are digital calls that connect to HDLC framers. Unlike ISDN, it is impossible to communicate the call type in CT1. Therefore, switched 56K services in CT1 can be differentiated by the DNIS numbers. This command identifies that the call arriving with the DNIS in the DNIS group is assigned to the call type specified in the command.

Examples

The following example shows the DNIS group configuration mode being accessed to use the call-type cas command to set the call type override for CAS to speech:

dialer dnis group modem-group1

 call-type cas speech

cas-custom

To customize E1 R2 signalling parameters for a particular E1 channel group on a channelized E1 line, use the cas-custom command in controller configuration mode. Use the no form of this command to disable the signalling customization.

cas-custom channel

no cas-custom channel

Syntax Description

channel

Specifies a single channel group number, which can be from 0 to 30. This channel group number must match the channel number specified in the cas-group command.

Defaults

No customized signalling parameters are set. If you do not specify a country name using the country name command, which is described in Table 4, ITU is the selected default signal.

Command Modes

Controller configuration

Command History

Release	Modification
11.2P	This command was introduced.
12.0(1)T	This command was introduced for the Cisco 3600 series routers.

Usage Guidelines

The customization parameters set by the cas-custom channel command are applied to the same channel group number used in the cas-group channel timeslots range type signal command. These channel group numbers must match. Otherwise, the customized features specified by the cas-custom command will not be applied to the cas-group command's configuration. The signalling customization will not take effect. See Example 1.

However, you will not need to configure or set more than one channel group number per E1 line in most cases. Though rarely used, it is possible to split a single E1 (time slots 1 to 31) into two groups (for example, 1 to 15 on group 1 and time slots 17 to 31 in group 2).

Cisco strongly recommends that you use the optional use-defaults keyword when specifying a particular country type; see the country name command in Table 4. This additional keyword ensures that all the local country settings are correctly enabled. For example, issue the country greece use-defaults command. If the use-defaults option is not specified, generic ITU will be the default setting for all countries. See Example 2.

You can configure the system to deviate from a country's default settings as defined by Cisco. To do this, choose from the following list of commands described in Table 4: ani-digits min number max number, answer-signal {group-a | group-b} number, caller-digits number, category number, dnis-digits min number max number, invert-abcd, ka number, kd number, metering, nc-congestion, and unused-abcd value. To return a country back to its country specific default settings, issue the country name use-defaults command. To return a country back to the ITU standard, issue the default country name use-defaults command. See Example 3 and Example 4.

---

Note Only integrated MICA technologies modems support E1 R2 signalling on Cisco 5000 series access servers and Cisco 3600 series routers.

Command	Description
cas-group (E1 controller )	Configures channel associated signalling on an E1 controller.

cas-group (E1 controller)

To configure channel-associated signalling (CAS) on an E1 controller, use the cas-group command in controller configuration mode. Use the no form of this command to disable CAS for one or more time slots.

cas-group channel timeslots range type signal

no cas-group channel timeslots range type signal

Syntax Description

channel	Specifies a single channel group number. Replace the channel variable with a number between 0 and 30.
timeslots range	Specifies a time slot range, which can be from 1 to 31. You can specify a time slot range (for example, 1-29), individual time slots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-14, 15, 17-31). The 16th time slot is reserved for out-of-band signalling.
type signal	Specifies the type of channel associated signalling. Configure the signal type that your central office uses. For a Cisco 5800 series access servers, replace the signal variable with one of the following signal types: •e&m-fgb [dtmf [dnis] | mf [dnis]]—Specifies ear and mouth channel signalling with feature group B support, which includes the wink start protocol. The optional signal tones are DTMF and MF with the option of provisioning DNIS. •e&m-fgd—Specifies ear and mouth channel signalling with feature group D support, which includes the wink start protocol. •e&m-immediate-start—Specifies ear and mouth channel signalling with immediate start support. •fxs-ground-start—Specifies Foreign Exchange Station ground start signalling support. •fxs-loop-start—Specifies Foreign Exchange Station loopstart signalling support. •p7—Specifies the P7 switch type. •sas-ground-start—Specifies Special Access Station ground start signalling support. •sas-loop-start—Specifies Special Access Station loopstart signalling support.
	•r2-analog [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]] •r2-digital [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]] •r2-pulse [dtmf | r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]] For the Cisco 3600 series access servers, replace the signal variable with one of the following signal types: •r2-analog {r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]} •r2-digital {r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]} •r2-pulse {r2-compelled [ani] | r2-non-compelled [ani] | r2-semi-compelled [ani]}
	The following descriptions are provided for the previous R2 syntax bullets: r2-analog—Specifies R2 ITU Q411 analog line signalling, which reflects the on/off switching of a tone in frequency-division multiplexing circuits (before TDM circuits were created). The tone is used for line signalling. r2-digital—Specifies R2 ITU Q421 digital line signalling, which is the most common signalling configuration. The A and B bits are used for line signalling. r2-pulse—Specifies R2 ITU supplement 7 pulse line signalling, which is a transmitted pulse that indicates a change in the line state. dtmf—Specifies the DTMF tone signalling (Cisco 5800 series access server only). r2-compelled [ani]—Specifies R2 compelled register signalling. You can also specify provisioning the ANI address option. r2-non-compelled [ani]—Specifies R2 noncompelled register signalling. r2-semi-compelled [ani]—Specifies R2 semicompelled register signalling.

Defaults

No CAS is configured on the controller. All R2 signalling types have DNIS turned on by default.

Command Modes

Controller configuration

Command History

Release	Modification
11.2P	This command was introduced.
12.0(1)T	This command was introduced for the Cisco 3600 series router.

Usage Guidelines

Use this command to configure support for incoming and outgoing call signals (such as on-hook and off-hook) on each E1 controller.

If you specify the time slot range 1-31, the system software automatically uses the 16th time slot to transmit the channel associated signalling.

The signalling you configure on the access server must match the signalling used by the central office. For example if the central office switch is forwarding R2 analog signalling to a Cisco AS5800, then the access server's E1 controller must also be configured for R2 analog signalling (r2-analog).

All R2 signalling options have DNIS support turned on by default. If you enable the ani option, the collection of DNIS information is still performed. Specifying the ani option does not disable DNIS. DNIS is the number being called. ANI is the caller's number. For example, if you are configuring router A to call router B, then the DNIS number is router B, the ANI number is router A. ANI is very similar to Caller ID.

To customize the R2 signalling parameters, refer to the cas-custom controller configuration command. When you enable the cas-group command, the cas-custom command is automatically setup to be polled for configuration information. However, unless you enable or turn on specific features with the cas-custom command, the cas-custom feature has an empty set of signalling parameters.

---

Note Only integrated MICA modems support E1 R2 signalling on Cisco access servers.

---

DNIS is automatically collected for modem pools and R2 tone signalling. You do not need to specify the collection of DNIS information with the cas-group command. However, if you are using non-R2 tone signalling, the system must be manually configured to collect DNIS information. For non-R2 cas signalling, DNIS collection is done only for E&M-fgb.

Examples

In most cases, you will configure the same channel-associated signalling on each E1 controller. The following examples configure signalling and customized parameters on controller E1 2 using the cas-group and cas-custom controller configuration commands.

The following example configures the E1 controller on a Cisco 5800 series access server.

To configure a Cisco 3600 series access server, replace the command:

controller e1 2/1/0

with the command:

controller e1 2

---

Note The actual channel associated signalling is configured on the 16th time slot, which is the reason why this time slot does not come up in the following output.

Syntax Description

channel	Specifies a single channel group number. Replace the channel variable with a number between 0 and 30.
timeslots range	Specifies a time slot range, which can be from 1 to 24 for T1, and from 1 to 31 for E1. You can specify a time slot range (for example, 1-31), individual time slots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-7, 8, 17-31). The 16th time slot is reserved for out-of-band signalling.
type signal	Specifies a type of robbed-bit signalling. Replace the signal variable with one of the following signal types. The keywords service, data, and voice are used for switched 56K configuration. These keywords are described at the end of this syntax description table. •e&m-fgb [dtmf [dnis] | [service {data | voice}]] | [service {data | voice}] | [mf [dnis] | [service {data | voice}]]—Specifies ear and mouth channel signalling with feature group B support, which includes the wink start protocol. Use the options dtmf [dnis] to configure DTMF tone signalling with optional DNIS provisioning. Use the options mf [dnis] to configure MF tone signalling with optional DNIS provisioning. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information about these switched 56K keywords.)
	•e&m-fgd [service {data | voice}]—Specifies ear and mouth channel signalling with feature group D support, which includes the wink start protocol. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.)
	•e&m-immediate-start [service {data | voice}]—Specifies ear and mouth channel signalling with immediate start support. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.)e&m-immediate-start [service {data | voice}]—Specifies ear and mouth channel signalling with immediate start support. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.)
	•fxs-ground-start [service {data | voice}]—Specifies Foreign Exchange Station ground start signalling support. Use the options [service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.) •fxs-loop-start [service {data | voice}]— Specifies Foreign Exchange Station loopstart signalling support. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.) •r1-modified ani-dnis—Indicates R1 signalling will collect ani and dnis information. •r1-modified dnis—Indicates R1 signalling will collect only dnis information. •sas-ground-start [service {data | voice}]—Specifies Special Access Station ground start signalling support. Use the options service {data | voice} for switched 56K configurations. (See the end of this syntax description table for more information.) •sas-loop-start [service {data | voice}]—Specifies Special Access Station loopstart signalling support. Use the options service {data | voice} for switched 56K configurations. •service—(Optional) Specifies the type of services provided for scenarios involving switched 56K connections. Do not include this option in the cas-group command statement if you are not using the access server to provide switched 56K connections. •data—Enables switched 56K digital data services on the specified range of time slots. The data is directly read from the time slot or channel. Time slots configured with this option will not accept analog modem calls. •voice—Enables analog modem services on the specified range of time slots. The call is forwarded to the modems for demodulation. Time slots configured with this option will not accept switched 56K digital calls.

Defaults

For ISDN PRI, the cas-group command is disabled.

If the channelized T1 is not configured as a PRI, the default value for line signalling is e&m-fgb and the default value for tone signalling is DTMF.

The R1 signalling default value is ani-dnis.

Command History

Release	Modification
11.2	This command was introduced.
11.3T	The following signalling options were added: •service •data •voice The R1 keyword was added.

Usage Guidelines

Use the cas-group command to configure T1 controllers with different types of robbed-bit signalling, such as on-hook and off-hook for E&M feature group B (e&m-fgb).

If you want to collect DNIS information on a T1 controller, you must manually configure it on the access server. DNIS collection is performed only for E&M-fgb. To collect DTMF DNIS for E&M-fgb under a controller T1 configuration, enter the cas-group 0 timeslots 1-24 type e&m-fgb dtmf dnis command. To collect MF DNIS for E&M-fgb, enter the cas-group 0 timeslots 1-24 type e&m-fgb mf dnis command.

Examples

The following example configures all 24 channels with ear and mouth robbed-bit signalling with feature group B support:

# controller T1 0
