ISDN Commands

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

demand

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

DEmand [link] [THreshold = kbps] [DUration= seconds] [SOurce =WAN | LAn | BOth]

Syntax Description

link	Specifies the link with which all the following parameters are associated.
threshold	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	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	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 or profile mode

Usage Guidelines

On-demand dialing must be enabled with the set auto command.

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 link 1 will dial if 10 kbps is exceeded continuously for two seconds.

Related Commands

set auto
set delay
set ppp callback
set ppp negotiation retry
set ppp negotiation count
set ppp bacp
set ringback
set timeout
timeout
show negotiation

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 is made.

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

Related Command

set number

establish

To reassign a released service profile identifier (SPID) to the router, use the establish command.

EStablish [spid id]

Note This command is applicable to US switches only.

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 mode

Usage Guidelines

This command is applicable only in the United States. It reassigns one of the SPIDs after it has been released to a device other than the router. For example, if you have two SPIDs and the router is using both of them for data. One of the SPIDs has to be released if an ISDN phone is to be used.

Example

The following example reassigns the SPID ID2 to the router following a release:

establish 2

The following is a typical sequence of events:

A unit has two calls established.
A call is disconnected by the user to free the B channel.
User releases the second SPID by entering: REL 2. The message "Terminal Identifier Unassigned" displays.
The same SPID is activated by the user in another ISDN TE on the same DSL.
Use of the other TE is finished and the user frees the SPID.
User reactivates the SPID in the unit by entering: ES 2.
A second channel call is made by the user of the unit.

Related Command

release

release

To release the Layer 2 link and Terminal Identifier (TEI) Unassigned associated with a SPID, use the release command.

RElease [spid id]

Note This command is applicable only to switches used in the United States.

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 mode

Usage Guidelines

This command is used to release a SPID being used by the router, so that it can be used by another device on the same ISDN line (SBus). Use this command when your ISDN line only supports two SPIDs and one B channel per SPID (DMS-100). When released, the SPID still resides in memory, so you do not have to reenter the SPID. To reassign the SPID back to the router, use the establish command.

Example

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

Host> release 1

Related Command

establish

reset directory number

To delete one or all of the directory numbers, use the reset directory number command.

set autodetection

To enable or disable automatic service profile identifiers (SPID) detection, use the set autodetection command.

SEt AUTODetection ON | OFf

Note This command is available only in the US image.

Syntax Description

on	Specifies a US and Canada switch with auto detection enabled. You must enter the directory number, including the area code.
off	Disables the auto detection feature. You must enter the SPID numbers and switch type.

Default

Off

Command Mode

System mode

Usage Guidelines

The auto-SPID and auto-switch detection features simplify the use of ISDN terminal equipment, because there are fewer parameters to enter. Before the feature is enabled, the user only enters the local directory numbers and area code. No SPID number or switch type is required. This reduces the possibility of mistakes made by the user or the carrier. It also allows less sophisticated users to operate ISDN equipment.

During the detection process, the control software tries to register SPIDs with the switch based on the local directory numbers and area code. After a successful registration, the control software stores the detected SPIDs and switch type in NVRAM, as if they were entered by the user.

If auto detection fails to register SPIDs with the ISDN switch, the system prompts the user with an error message. The user will be required to manually enter SPID number(s) and switch type.

The auto detection feature only applies to USA and Canada ISDN switches which are most likely a 5ESS Custom, DMS100 Custom, NI-1, or NI-2 switch. The auto detection mechanism might not work with any other switch, such as Siemens switch.

The user can enter up to six directory numbers in software Release 4.0(1) and higher, three for each interface. Including the area code helps the auto detection software speed up the registration process.

The following limitations are inherit in SPID autodetection.

If the service provider has assigned SPIDs that cannot be generated by the search table, the feature does not work.
The test call does not work if other router features are attempting to make calls while detection is in progress. It is recommended that the LAN not be connected to the router while detection is in progress.
You must not attempt to make a voice call while SPID detection is in progress.
An incoming call can cause the feature to fail or to incorrectly determine that the test call was successful.
The detection procedure requires approximately 30 seconds for each table entry. The current table size suggests a maximum time of approximately 12 minutes to complete the SPID detection process.
The SPID detection procedure places a burden on the switch connected to a Cisco 700 series router. Therefore, the feature disables itself after it has finished the process. It is recommended that the feature is used only during installation and that it be invoked sparingly.

Example

The following example disables on-demand dialing for the second channel:

Host> set 1 directorynumber 4085551234
Host> set 2 directorynumber 4085552345
Host> set autodetection on

link	A logical 64/56 kbps data path assigned to users, numbered sequentially beginning with one. The unit is limited to two links.
backupnumber	A 1 to 20 digit telephone number of a device.
.subaddress	Subaddress of a device on a multipoint ISDN line. Can consist of 1 to 10 digits.

Related Commands

set delay

To set the time between unsuccessful demand call attempts, use the set delay command.
SEt [link] DElay seconds
Syntax Description

link Link to which the delay time applies. If no link is entered, the delay time is set for both links.
delay Time in seconds between unsuccessful call attempts. This value can be between 10 and 32767 seconds. Another call is attempted when the delay time has expired only if the parameters set by the demand command are met.

Default

Link 1--30
Link 2--30

Command Mode

System mode

Usage Guidelines

The delay time applies to all ISDN demand call attempts.

If the 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.

Example

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

Host> set 1 delay 15

Default

Normal

Command Mode

Profile mode

Usage Guidelines

The numbering plan is the type of telephone numbering plan the router uses when making calls. Numbering plans are predefined settings that configure calls so that they conform to telephone system requirements.

Example

The following example sets the router to use the international numbering plan when making calls:

Host> set plan international

set ringback

To set the router's ringback number, use the set ringback command.
SEt [link] RIngback [number [.subaddress]]
Syntax Description

link 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 sent to the remote router to make a callback to the Cisco router. (Your local router phone number.) 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 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

The ringback number is the number string used by the remote router to make a callback to your router. If a remote router is calling in from a different area code, requires a different access codes or a country code, it might be necessary to specify that ringback number in each 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 1408555-1234, and the ringback number for a remote router on a PBX might be 95551234.

If BACP or BAP is used, the ringback number has another function; to make a second-channel call, the 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 telephone number is 555-5678, set the remote router's second-channel ringback number to 5678. The Cisco router uses 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

56	Outgoing calls are made and connected at 56 kbps. Incoming calls are connected at 56 kbps.
64	Outgoing calls are made and connected at 64 kbps. Incoming calls are connected at 64 kbps, unless Bearer Capability (BC) indicates the call is at 56 kbps. In this case, calls are connected at 56 kbps.

Default

The switch type depends on which image of the Cisco 700 software is loaded. For example, if your image is c760-in.b-US.41-1, the default is 5ESS.

Command Mode

System mode

Usage Guidelines

Not all switch settings are available to all users. The switch type available depends on the type of software loaded into the unit.

Example

The following example configures the ISDN switch type as DMS:

Host> set switch dms

set timeout

To configure the amount of time the ISDN line remains idle before disconnecting, use the set timeout command. This command sets the same parameter as the timeout duration command.
SEt [link] TIMEout [seconds | OFf]
Syntax Description

link The ISDN link to which the timeout parameters apply.
seconds Time (in seconds) that the ISDN line will remain idle before disconnecting. Can be between 1 and 32767 seconds.
off The ISDN line will not disconnect automatically.

Default

Off

set voicepriority

The set voicepriority command sets the voice priority mode. It determines if the system will disconnect a B channel assigned to a data call to allow a voice call.
SEt VOicepriority [INcoming | OUtgoing] [INterface=PHONE1
| PHONE2] ALways | COnditional | NEver
Syntax Description

incoming outgoing Indicates the direction of the call for which the priorities are being set. The default, when nothing is specified, is incoming.
interface Takes the values of PHONE1 or PHONE2. When neither is specified, it will apply to both PHONE1 and PHONE2.
always Sets voicepriority to be active under all circumstances. Data calls are always bumped for voice calls.
conditional Sets voicepriority to disconnect data calls only if the network connection can be guaranteed (that is only if there are two data calls to the same destination).
never Disables voicepriority; data calls are never bumped for voice calls.

Default

Always

Command Mode

System mode

Usage Guidelines

Voice priority can be set in a variety of ways. Table 5-3 lists the settings and the modes for inbound calls.

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 The link to which the timeout parameters apply.
threshold Data rate in kbps. If the data rate falls below the specified threshold for the specified duration, the ISDN line disconnects.
duration Length of time, in seconds, that the traffic must be below the threshold before the ISDN line is disconnected.
source 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

Related Command

set timeout

object	Can consist of a link or a channel.
number	The telephone number of the remote ISDN device. If no telephone number is entered, the router calls 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.

object	ISDN B channel or link. Can be 1 or 2. If no channel or link is entered, any connected calls are terminated.
All	Disconnects all calls.

standard	Used if no selection was made (the Standard profile telephone number is used). If you make more than one choice, the last one will be effective.
off	To disable the button, set it to OFF.

PHONE1 \| PHONE2	Sets the call waiting feature for each specified telephone interface.
on	Enables the call waiting feature.
off	Disables the call waiting feature.

link	Link to which the delay time applies. If no link is entered, the delay time is set for both links.
delay	Time in seconds between unsuccessful call attempts. This value can be between 10 and 32767 seconds. Another call is attempted when the delay time has expired only if the parameters set by the demand command are met.

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 is associated with SPID1 in the case of switches with SPIDs.
number	The directory number assigned by the telephone company. Can have 2 to 20 digits. For Cisco 760 and Cisco 770 series routers, a maximum of six directory numbers are allowed. For Cisco 750 series routers, a maximum of two directory numbers are allowed.
.subaddress	Subaddress of a device on a multipoint ISDN line. Can have 1 to 10 digits.

None	All tones are provided by the switch.
Dialtone	Dialtone is generated locally. All the other tones are provided by the switch.
All	All the tones are provided locally.

on	Enables multidestination dialing. The router, through the use of profiles, is able to connect to multiple remote locations over ISDN.
off	Disables multidestination dialing. If the router attempts to connect with two different remote routers, the connection to the second router is refused.

PHONE1 \| PHONE2	The telephone interface to which the voice calls will be routed. If no interface has been associated with an incoming voice call, the default routing will be to PHONE1.
DOV	(Data Over Voice) If a directory number is associated with the DOV interface, all incoming voice calls to that number will be treated as data over voice calls and routed to the Ethernet interface.
number	The directory number associated with that interface. There is one directory number per telephone interface. Two directory numbers can be assigned to be data over voice.
.subaddress	Subaddress of a device on a multipoint ISDN line. This number can have 1 to 10 digits.
ring 1	Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 1 signals DRM to route the incoming call to output port 1.
ring 2	Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 2 signals DRM to route the incoming call to output port 2.
ring3	Specifies the ringing cadence. If the ringing cadence is not specified, the original country's tone is generated. Ring 3 signals DRM to route the incoming call to output port 3.

normal	Unknown numbering type with unknown numbering plan (most common case).
international	The international numbering type with ISDN numbering plan.
national	The national numbering type with ISDN numbering plan.
