ISDN Calling Commands
This chapter describes the commands used to configure Integrated Services Digital Network (ISDN) calling, such as on-demand dialing and security.
Configuring Directory Numbers
This section describes the association between the ISDN directory numbers, the service profile identification numbers (SPIDs) and the analog telephone port(s) of the router.
Note
Detailed information regarding the commands discussed in this chapter are provided in the Cisco 700 Series Router Command Reference.
SPIDs and Directory Numbers
SPIDS are in common use only in North America. If you are using ISDN Basic Rate Interface (BRI) service in North America, your telephone service provider might assign zero, one, or two SPIDs to your BRI line, depending on what kind of switch the service provider uses. For 5ESS Custom switches, no SPID is assigned if the service provider is using a point-to-point switch, and one SPID is usually assigned for a multipoint switch. For DMS-100, NI1 and NI1-compliant switches, two SPIDs are usually assigned. All other switch types usually do not use SPIDs.
If your BRI line is assigned two SPIDs, it is suggested that you use the first SPID directory number for data calls and the second SPID directory number for the incoming voice calls to reduce the chances a data call will be disconnected when the router receives incoming voice calls.
SPIDs define the services available to the router. SPID numbers are determined by your service provider. For example, a directory number is considered a service and is associated with a SPID. A SPID can have more than one directory number associated with it. Cisco 700 series routers support up to three directory numbers for each SPID and up to two SPIDs, for a total of six directory numbers.
Analog Telephone Ports
The analog telephone ports are basic telephone service (POTS) ports, as opposed to an ISDN telephone port, such as the S/T port. The POTS ports are mapped to the directory numbers.
Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers have two analog telephone ports. The phone numbers for the ports are assigned using the set phone command. However, if your BRI line is assigned zero or one SPID, only one analog telephone port can be used at one time. If your BRI line is assigned two SPIDs, both analog telephone ports can be used simultaneously.
If no directory numbers are associated (mapped) to the POTS ports, the default function of analog telephones is dependent on the number of SPIDs assigned to the ISDN BRI line. Table 5-1 describes the default behavior of the POTS ports if your SPIDs and directory numbers are defined and you do not use the set phone command to configure the POTS ports.

Data Over Voice Bearer Service
This section applies only to North American analog telephone services.
The router recognizes the difference between a data call and a voice call. In some tariff areas, voice calls are less expensive than data calls. Cisco 700 series routers support incoming and outgoing DOV calls. DOV calls are data calls made over the BRI (voice) line using Voice Bearer Capability (VBC).
If a directory number has been configured for DOV, incoming data calls with VBC are routed to the LAN through the Ethernet port, as shown in Figure 5-1. Incoming voice calls are forwarded to the analog (voice) device over the analog telephone port, as shown in Figure 5-2.
Figure 5-1 Data Call with VBC
Figure 5-2 Voice Call over VBC Line
The set dov command instructs the router to treat incoming calls to a specified directory number as data calls. (Before using the set phone command to configure DOV, you must set the directory number with the correct SPID, as described in the section "Configuring Directory Numbers," in this chapter.)
Any call received on the port that has been associated with this directory number is treated as DOV and is forwarded to the LAN. One or two directory numbers can be configured for DOV with the set phone command.
The set speed command with the voice keyword sets VBC on for outgoing DOV calls, enabling the features of VBC and DOV.
Automatic Data Call Disconnect
You can automatically disconnect a data call when a voice call is made or received and two data calls are in progress. The set voicepriority command determines if a data call will be disconnected when the router makes or receives a voice call.
If the priority is set to always, data calls are always bumped in favor of voice calls.
If the priority is set to conditional, the data call is disconnected from one channel if the data call can continue over another channel.
If the priority is set to never, data calls are never bumped in favor of voice calls.
If the priority is set to disable, data calls are handled as indicated by the set phone DOV command.
The voice priority mode is dependent on several factors, including the following:
•
•
Distinctive Ringing
Cisco 700 series routers have a Distinctive Ring Manager (DRM) that can support distinctive ringing cadences for up to six external devices using the set phone command. These external devices can be a telephone or fax machine. Each POTS interface can support up to three devices.
call
To make a manual ISDN call on a specified link to a specified telephone number, use the call command.
CAll [object] [number]
Syntax Description
Default
None
Command Mode
System or profile mode
Usage Guidelines
The object parameter can take one of these forms:
1
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#2
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 #/#3
Channels provide a physical data path over the WAN. Channels are one or more time slots kept in sequence through the WAN that do not require any kind of inverse multiplexing. The unit can support 64-kbps channels or (in INS release only) 128-kbps channels. The syntax format for a channel is as follows:
CH#The # parameter can be 1 or 2.
If no link number is specified, the call is placed on both links. If no destination telephone number is specified, the unit uses the number configured for the current profile.
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 4085551212Related Commands
set button
set numberdemand
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 might actually exceed the physical capacity of the line.
Default
Channel 1—threshold 0 duration 1 source lan
Channel 2—threshold 48 duration 1 source bothCommand 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:
Host:2503> demand 1 threshold 10 duration 2 source lanThis specifies that link 1 will dial if 10 kbps is continuously exceeded for 2 seconds.

To manually terminate an ISDN call, use the disconnect command.
DIsconnect [object | ALl]
Syntax Description
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.
Default
None
Command Mode
Profile mode
Usage Guidelines
The object parameter can take one of these forms:
1
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 a connection is as follows:
C#2
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 #/#3
Channels provide a physical data path over the WAN. Channels are one or more time slots kept in sequence through the WAN that do not require any kind of inverse multiplexing. The unit can support 64-kbps channels or (in INS release only) 128-kbps channels. The syntax format for a channel is as follows:
CH#The # parameter can be 1 or 2.
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.
Examples
The following example disconnects a call on the first link:
Host> disconnect 1The following example disconnects any calls on both links of the current connection:
Host> disconnectRelated Command
set number
establish
To reassign a released service profile identifier (SPID) to the router, use the establish command.
EStablish [spidid]
Note
Syntax Description
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:

release
release
To release the Layer 2 link and Terminal Identifier (TEI) Unassigned associated with a SPID so that it can be used by another device on the same ISDN line (SBus), use the release command.
RElease [spidid]
Syntax Description
spidid
Specify the number of the SPID you are releasing (1 or 2) as set by the set spid command. (North America only.)
Default
None
Command Mode
System mode
Usage Guidelines
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 1Related Command
establish
reset directory number
To delete one or all of the directory numbers, use the reset directory number command.
REset DIrectorynumber ALl | number [.subaddress]

set aoctimeout
To extend the connection (after the idle time out has expired) based on the frequency of the Advise of Charge During Call (AOC-D), use the set aoctimeout command. The feature is also known as the fee pulse mode.
SEt AOctimeout ON [seconds] | OFf
Note
Syntax Description
Default
4 seconds
Command Mode
Profile mode
Usage Guidelines
The aoctimeout command can only be used in conjunction with the set timeout command. Before using this command, configure the set timeout command parameters, threshold kbps and duration seconds.
Example
The following example enables the use of AOC-D supplemental service:
Host: set aoctimeout on
Related Command
set timeout
set alawvoice
To set voice encoding, use the set alawvoice command.
SEt ALawvoice ON | OFf
Note
Syntax Description
Default
On
Command Mode
System mode
Usage Guidelines
For the NET3 switch type, the set alawvoice command changes the voice encoding to micro-law for countries such as Taiwan. Most countries that use the NET3 switch type use A-law voice encoding. This command is needed for countries (such as Taiwan) that require micro-law.
Example
The following example sets voice encoding to A-law:
Host> set alawvoice onset auto
To enable or disable on-demand dialing, use the set auto command.
SEt [link] AUto ON | OFf
Syntax Description
Default
channel 1—enabled (on)

Profile mode
Example
The following example disables on-demand dialing for the second channel:
Host> set 2 auto offRelated Commands
demand
set ppp callback
set ppp negotiation retry
set ppp negotiation count
set ppp bacp
set ringback
set timeout
show negotiationset autodetection
To enable or disable automatic service profile identifiers (SPID) detection, use the set autodetection command.
SEt AUTODetection ON | OFf
Note
Syntax Description
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.
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 North American ISDN switches, usually a 5ESS Custom, DMS-100 Custom, NI1, or NI2 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 auto detection.

To set a backup number, use the set backupnumber command.
SEt [link] BackupNUmber = [subaddress]
Syntax Description
Command Mode
Profile mode
Usage Guidelines
Cisco 700 series routers can place a call to a backup telephone number when an outgoing call is made. The call might not be successful because the receiving side is busy or does not answer. Cisco 700 series routers support second number fail-over for manual and auto data calls. Both the called number and the backup numbers must be configured.
Example
The following example sets up a backup number:
Host> set backupnumber 18885551212Related Command

set delay
To set the time between unsuccessful demand call attempts, use the set delay command.
SEt [link] DElay seconds
Syntax Description
Default
Link 1—30 seconds
Link 2—30 secondsCommand 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 condition 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 15Related Command
demand
set backup numberset directorynumber
To enter the router directory number, use the set directorynumber command.
SEt [spidid] DIrectorynumber = number [.subaddress]

PErmanent
Specifies permanent mode of operation.
ON
Enables permanent mode.
OFf
Disables permanent mode.
Default
Off
Command Mode
Profile mode
Usage Guidelines
Customers and Internet service providers (ISPs) in areas served by carriers providing flat-rate ISDN can have their lines connected permanently. This overrides any timeout and threshold parameters. It also allows the flexibility of having one or more channels permanently up.
This feature is not dependent on the switch for permanent connections and can work on any switch type.
On power up, the router tries to bring up all permanent connections. If for any reason a connection gets disconnected, the router attempts to reconnect.
If permanent mode is specified for more than one link on a single profile, all links come up only if Multilink PPP is configured. If the D channel is configured for permanent mode, it comes up only if no other B channels are active.
If the idling D channel configured for permanent mode is disconnected, it will not come up if any B channel is already connected, until the B channel call is discontinued. Permanent mode can be configured for three links only, two B channels and the D channel, across all profiles. If you enter this command after having configured it for two B channels and the D channel, an error message displays on the console screen.
The permanent mode setting overrides only timeout and threshold parameters and not other events such as
•
•
•
These events cause the line to be disconnected, but in permanent mode the router attempts to restore the line immediately.
