ISDN Commands

ISDN Commands

This chapter describes the commands you use to configure Integrated Services Digital Network (ISDN) calling, such as on-demand dialing and security.

Note The command syntax includes a combination of bold and regular uppercase and lowercase alphanumeric characters. You can enter commands in full or you can enter abbreviated forms of many commands. The abbreviated form consists of the first characters in each word of the syntax that appear in bold uppercase type in command syntax in this chapter. These characters represent the minimum you must enter for the command to be recognized and executed.


call

To make a manual ISDN call on a specified link to a specified phone number, use the call command. If no link number is specified, the call will be placed on both links. If no destination phone number is specified, the unit will use the number configured for the current profile.

CAll [object] [<number>]


Syntax Description

object Can consist of a link or a channel.
number (Optional) The telephone number of the remote ISDN device. If no telephone number is entered, the router will call the number configured in the current profile with the set number command. If no number is entered and the current profile has not been configured with a number, this command has no effect.


Default

None


Command Mode

Profile mode


Usage Guidelines

The object parameter can take one of three forms, described below.

  1. Connection
    A logical data stream that connects the unit to the remote device. A connection can have multiple links associated with it. The syntax format for connection is as follows: 
C#

  1. Link
    A logical 64/56kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links. The two syntax formats for link are as follows: 
L# or #
The # parameter can be either 1 or 2.
The three syntax formats for a connection and an associated link are as follows: 
C#/L# or C#/# or #/#

  1. Channel
    Channels provide a physical data path over the WAN network. Channels are one or more time slots kept in sequence through the WAN network that do not require any kind of inverse multiplexing. The unit can support 64K channels or (in INS release only) 128K channels. The syntax format for a channel is as follows: 
CH#
The # parameter can be 1 or 2.


Example

The following example makes a manual call on the second link to 408 555-1212 while in profile mode for profile 2503: 

Host:2503> call 2 4085551212


Related Command

set number


demand

To specify when an on-demand ISDN call will be made, use the demand command.

DEmand [<link>] [THreshold =kb/s] [DUration= <seconds>] [SOurce =WAN | LAn | BOth]]


Syntax Description

link Specifies the link with which all the following parameters are associated.
threshold kb/s (Optional) Minimum data rate (in kbps) that must exist on the channel before the call will be made. The range is 0 to 128.1
Inband negotiation traffic (traffic that terminates at the router) is not taken into account for the threshold level.
duration seconds (Optional) Length of time (in seconds) that the traffic is to be above the data threshold before the call is made. The range is 1 to 255.
source (Optional) Source of traffic that is counted.
wan Traffic received from the ISDN line.
lan Traffic received from the LAN.
both The value of LAN or the ISDN traffic, whichever is higher.

1 The data rate measured is the data that the router intends to forward across the ISDN line, so the data rate may actually exceed the physical capacity of the line.


Default

Channel 1---threshold 0 duration 1 source lan
Channel 2---threshold 48 duration 1 source both


Command Mode

System level or profile mode


Usage Guidelines

On-demand dialing must be enabled with the set auto command for these setting to take effect.


Example

The following example determines when on-demand dialing will take place for profile 2503's connection: 

Host:2503> demand 1 threshold 10 duration 2 source lan

This specifies the first demand call.


Related Command

set auto


disconnect

To manually terminate an ISDN call, use the disconnect command.

DIsconnect [object | ALl]


Syntax Description

object (Optional) ISDN B channel or link. Can be either 1 or 2. If no channel or link is entered, any connected calls are terminated.


Default

None


Command Mode

Profile mode


Usage Guidelines

The object parameter can take one of three forms, described below.

  1. Connection
    A logical data stream that connects the unit to the remote device. A connection can have multiple links associated with it. The syntax format for connection is as follows: 
C#

  1. Link
    A logical 64/56 kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links. The two syntax formats for link are as follows: 
L# or #
The # parameter can be either 1 or 2.

The three syntax formats for a connection and an associated link are as follows: 
C#/L# or C#/# or #/#

  1. Channel
    Channels provide a physical data path over the WAN network. Channels are one or more time slots kept in sequence through the WAN network that do not require any kind of inverse multiplexing. The unit can support 64K channels or (in INS release only) 128K channels. The syntax format for a channel is as follows: 
CH#
The # parameter can be 1 or 2.


Example

The following example disconnects a call on the first link: 

Host> disconnect 1

The following example disconnects any calls on both links of the current connection: 

Host> disconnect

Note The router may automatically reconnect the call after using the disconnect command. This can occur if on-demand dialing is enabled and a telephone number has been entered with the set number command. If the router receives enough packets to meet the demand threshold parameters, a new call will be made.


establish

To reassign a released service profile identifier (SPID ID) to the Cisco 750 or and Cisco 60 series router use the establish command.

EStablish [<spid id>]


Syntax Description

spid id Specify the number of the SPID you are establishing (1 or 2) as set by the set spid command.


Default

None


Command Mode

System level


Usage Guidelines

This command is used to reassign one of the Cisco router's SPIDs after it has been released to a device other than the Cisco router. This command is applicable only in the United States.


Example

The following example releases and reassigns the SPID ID2 to the Cisco router following a previous release.

ES tablish 2

The following outlines a typical sequence of events:

  1. A unit has two calls established.

  2. The user disconnects a call to free the B-channel.

  3. The user releases the second SPID by entering: REL 2.

  4. The message "Terminal Identifier Unassigned" is displayed.

  5. The user activate the same SPID in another ISDN TE on the same DSL.

  6. The user completes use of the other TE and frees the SPID.

  7. The user reactivates the SPID in the unit by entering: ES 2.

  8. The user makes a second channel call on the unit.


Related Command

release


release

The release command allows you to release the Layer 2 link and Terminal Identifier (TEI) Unassigned associated with a SPID. When released, the SPID will still reside in configuration memory so you will not have to reenter the SPID.

RElease [<spid id>]


Syntax Description

spid id Specify the number of the SPID you are releasing (1 or 2) as set by the set spid command.


Default

None


Command Mode

System level


Usage Guidelines

This command is used to release a SPID being used by the Cisco 750 series or Cisco 760 series routers, so that it can be used by another device on the same ISDN line (S-Bus). Use this command when your ISDN line only supports two SPIDs and 1 B channel per SPID (DMS-100). To reassign the SPID back to the Cisco 750 series or Cisco 760 series router, use the establish command. This command is applicable to US switches only.


Example

The following example releases the Channel 1 SPID from the Cisco router so that it can be used by another device on the same ISDN line: 

Host> release 1


Related Command

Usage Guidelines

The delay time applies to all ISDN demand call attempts.


Example

The following example sets the first channel to retry demand calls at most every 15 seconds: 

Host> set 1 delay 15

Note If the Cisco routers at both ends of an ISDN connection are configured with on-demand dialing enabled and the same delay time, unsuccessful calls can lead to a nonterminating error condition. This occurs when each router repeatedly tries to call the other at exactly the same delay time. Neither call will be successful, and both routers will repeat the call attempt at the same delay interval.


set directory number

To enter the router's directory number, use the set directory number command.

SEt [<spid id>] DIrectorynumber =<number> [.subaddress]


Syntax Description

spid id The SPID ID can be 1 or 2. Depending on your ISDN service provider, your line may be assigned one or two SPIDs. Must be used if the switch has SPIDS, otherwise ignore this field.
If no SPID ID is specified, the directory number will be associated with SPID1 in the case of switches with SPIDs.

set power source detect

To set the router to detect Power Source 1, use the set powersource detect command.

SEt PS1 ON | OFf

Note This command only applies to routers with analog phone support.


Syntax Description

on Sets the router to detect Power Source 1.
off Use in areas that do not support Power Source 1.


Default

on


Command Mode

System level


Usage Guidelines

This command only applies outside of the United States.


Example

The following example enables the router to use Power Source 1: 

Host> set ps1 on


set ringback number

To set the router's ringback number, use the set ringback number command. The ringback number is used by the remote router to make a callback to the router.

SEt [link] RIngback =[<number> [.subaddress>]]


Syntax Description

link (Optional) The ISDN B channel to which the ringback number applies. Can be 1 or 2. If no channel is specified, the ringback number applies to both channels.
number The number used by the remote router to make a callback to the Cisco router. Can be 1 to 32 digits. This number must include all the digits necessary for the remote router to complete a call to the Cisco router, for example, area and access codes.
.subaddress (Optional) Specifies a particular device on a multipoint ISDN line. Can be 1 to 10 digits.


Default

No ringback number is configured.


Command Mode

Profile level


Usage Guidelines

If remote routers are calling in from different area codes, or different access codes, it may be necessary to specify the ringback number in each router's profile. For example, the ringback number for a remote router in the same area code might be 555-1234 while the ringback number for a remote router outside the area code might be 1 408-555-1234, and the ringback number for a remote router on a PBX might be 9-555-1234.

In addition to being the remote router's callback number, the ringback number has another function. To make a second-channel call, the Cisco router uses a combination of the number it used to make the first-channel call and the remote router's second-channel ringback number.

For example, the Cisco router calls 555-1234 to reach the first channel of the remote router. If the second channel phone number is 555-5678, set the remote router's second-channel ringback number to 5678. The local router will use the prefix of the first number it called (555) plus the second channel's ringback number (5678) to make the second call.


Example

The following example sets the number that a remote router uses when making a callback to the Cisco router on the first ISDN B Channel: 

Host> set 1 ringback 14155551234


set speed

To set the speed of data calls, use the set speed command.

SEt SPeed 56 | 64 | AUto | VOice

timeout

To configure the parameters that specify when the ISDN line will be disconnected, use the timeout command. This is an expanded version of the set timeout command, which only allows you to specify duration.

TImeout <link> [THreshold =<kbps>] [DUration= <seconds>] [SOurce= WAn | LAn | BOth]


Syntax Description

link (Optional) The link to which the timeout parameters apply.
threshold (Optional) Data rate in kbps. If the data rate falls below the specified threshold for the specified duration, the ISDN line disconnects.
duration (Optional) Length of time, in seconds, that the traffic must be below the threshold before the ISDN line is disconnected.
source (Optional) Source of the traffic in reference to the threshold.
lan Timeout parameters apply to packets received from the LAN.
wan Timeout parameters apply to packets received from the ISDN line.
both Timeout parameters apply to packets received from the interface that has the most traffic, LAN or ISDN.


Default

Channel 1---threshold 0, duration off, source lan
Channel 2---threshold 48, duration off, source both


Command Mode

Profile mode


Usage Guidelines

If the set timeout command is configured to off, this command does not apply.


Example

The following example configures the router to disconnect the second channel if the data rate from either the LAN or the ISDN line falls below 64 kbps for 60 seconds: 

Host:2503> timeout 2 threshold 48 duration 60 source both
