ISDN commands
This feature is supported only on routers with E1 interface modules installed.
Before you can use a CE1/PRI interface to provide ISDN PRI services, you must use the pri-set command to bundle timeslots into channel sets on the interface. For each PRI set, the system creates a serial interface automatically. To configure ISDN settings for a PRI set, you must enter the view of this serial interface.
For more information about timeslot bundling, see WAN interface configuration in Interface Configuration Guide.

isdn bch-local-manage
Use isdn bch-local-manage to enable an ISDN interface to select ISDN B-channels for calls.
Use undo isdn bch-local-manage to restore the default.
Syntax
isdn bch-local-manage [ exclusive ]
undo isdn bch-local-manage
Default
B-channel selection is disabled on ISDN interfaces. The service provider switch selects B-channels for calls.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
exclusive: Specifies exclusive B-channel selection. If you do not specify this keyword, the command enables non-exclusive B-channel selection.
Usage guidelines
Typically, B-channel selection is done by the service provider switch. To improve call establishment efficiency and reduce call losses on ISDN lines, you can enable the ISDN interface to select B-channels for calls. This is particularly true for PRI ISDN lines.
· If non-exclusive B-channel selection is enabled, the interface selects a preferred B-channel for a call. However, it will use the B-channel selected by the peer end when a selection conflict occurs.
· If exclusive B-channel selection is enabled, the interface selects a preferred B-channel for a call. It does not accept the B-channel selected by the peer end when a selection conflict occurs.
|
|
IMPORTANT: Configure exclusive B-channel selection only when the interface is in network mode. In user mode, exclusive B-channel selection will cause a call establishment failure when a B-channel selection conflict occurs. |
Examples
# Enable non-exclusive B-channel selection on Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn bch-local-manage
isdn bch-select-way
Use isdn bch-select-way to set a B-channel selection method.
Use undo isdn bch-select-way to restore the default.
Syntax
isdn bch-select-way { ascending | descending }
undo isdn bch-select-way
Default
The device selects B channels in ascending order of channel IDs.

Predefined user roles
network-admin
Parameters
caller-number: Specifies an acceptable calling number, a case-sensitive string of 1 to 24 characters.
Usage guidelines
Calling number verification enables an ISDN interface to accept calls only from a specific calling party.
Call setup will fail in the following situations:
· The calling number in the incoming SETUP message is not configured on the ISDN interface.
· The incoming SETUP message does not include a calling number.
Examples
# Configure Serial 2/3/0:15 to accept incoming calls only from the calling number 400.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn caller-number 400
Related commands
isdn calling
isdn calling
Use isdn calling to configure ISDN calling number identification.
Use undo isdn calling to restore the default.
Syntax
isdn calling calling-number
undo isdn calling
Default
ISDN interfaces do not send a calling number in outgoing SETUP messages for any services except voice services.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
calling-number: Specifies a calling number, a case-sensitive string of 1 to 24 characters.
Usage guidelines
ISDN calling number identification enables an ISDN interface to include the call number of a calling party in the outgoing call SETUP messages. The calling number information can be used for different purposes. For example, the service provider can use this information to identify the pricing scheme for the calling party. The called party can use this information to verify the origin of calls.
For the called party to receive the calling number, the connected service provider switch must support transmitting calling numbers.
As a best practice, do not configure the calling number to be sent for voice services.
Examples
# Configure Serial 2/3/0:15 to include 8060170 as the calling number in outgoing SETUP messages.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial 2/3/0:15] isdn calling 8060170

Predefined user roles
network-admin
Parameters
check-index: Specifies a called-number verification index in the range of 1 to 3.
called-party-number: Specifies an acceptable called number. You can include a colon-separated subaddress when you specify the called number, for example, 66668888:13525. The value must be a case-sensitive string of 1 to 40 characters.
Usage guidelines
Called-number verification enables an ISDN interface to accept only calls placed to specific called numbers. You can configure the ISDN interface to verify only the called number or both the called number and the called subaddress. The ISDN interface will accept a call only if the called-number information matches one entry in the list of acceptable called numbers.
Examples
# Add 66668888:13525 to the list of acceptable called-numbers on Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15

network-admin
Parameters
call-reference-length: Specifies an ISDN call reference length, in bytes. Available values include 1 and 2.
Usage guidelines
Call reference is a sequence number that identifies a call. A call reference can be reused after it is released when its associated call is released.
When the router is connected to a peer device that cannot recognize the call reference length, you must configure the router with the same call reference length as the peer device.
You can configure the command only when no calls are present on the ISDN interface.
Examples
# Set the call reference length to 1 byte on PRI interface Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn crlength 1
isdn ignore connect-ack
Use isdn ignore connect-ack to enable ISDN to enter the ACTIVE state without an acknowledgment after it sends or receives a CONNECT request.
Use undo isdn ignore connect-ack to disable ISDN from entering the ACTIVE state without an acknowledgment after it sends or receives a CONNECT request.
Syntax
isdn ignore connect-ack [ incoming | outgoing ]
undo isdn ignore connect-ack [ incoming | outgoing ]
Default
After sending a CONNECT request, ISDN waits for a CONNECT ACK before it changes to the ACTIVE state for traffic transmission.
After receiving a CONNECT request, ISDN sends a CONNECT ACK and changes to the ACTIVE state.
Views

Predefined user roles
network-admin
Parameters
incoming: Specifies the incoming CONNECT ACK.
outgoing: Specifies the outgoing CONNECT ACK.
Usage guidelines
The setting for the command must be consistent with the setting on the service provider switch.
· If the service provider switch does not send CONNECT ACK, configure the isdn ignore connect-ack incoming command. After sending a CONNECT message, ISDN changes to the ACTIVE state without waiting for an acknowledgment.
· If the service provider switch does not receive CONNECT ACK, configure the isdn ignore connect-ack outgoing command. After receiving a CONNECT message, ISDN changes to the ACTIVE state without sending an acknowledgment.
You can configure the command only when no calls are present on the ISDN interface.
Examples
# On Serial 2/3/0:15, enable ISDN to change to the ACTIVE state after it sends a CONNECT request without waiting for a CONNECT ACK.

[Sysname-Serial2/3/0:15] isdn number-property 0 called out
isdn overlap-sending
Use isdn overlap-sending to enable overlap sending on an ISDN interface for called numbers.
Use undo isdn overlap-sending to restore the default.
Syntax
isdn overlap-sending [ digits ]
undo isdn overlap-sending
Default
En-bloc sending is enabled for called numbers. In the SETUP message, ISDN includes all information required by the network to process the call.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
digits: Specifies the maximum number of digits that can be sent in each SETUP message. The value range is 1 to 15, and the default is 10.
Usage guidelines
In overlap mode, called number information is absent or incomplete in each outgoing SETUP message.
Overlap sending is not available in ANSI, DSS1, ETSI, NI, or QSIG.
You can execute the command only when no call is present on the ISDN interface.
Examples
# Enable overlap sending on Serial 2/3/0:15, and configure the interface to send a maximum of 12 called-number digits in each SETUP message.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn overlap-sending 12
isdn pri-slipwnd-size
Use isdn pri-slipwnd-size to set the sliding window size on an ISDN PRI interface.
Use undo isdn pri-slipwnd-size to restore the default.
Syntax
isdn pri-slipwnd-size window-size
undo isdn pri-slipwnd-size
Default
The sliding window size is 7 on ISDN PRI interfaces.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
window-size: Specifies a sliding window size in the range of 5 to 64.
Usage guidelines
Q.921 sends frames in order of their sequence numbers and requires an acknowledgment of each transmitted frame. To improve transmission efficiency, Q.921 does not wait for a transmitted frame to be acknowledged before it sends the next frame. Instead, it uses a sliding window mechanism for transmission.
The sliding window mechanism enables Q.921 to send multiple continuous frames without waiting for the acknowledgment of the previous frame. The sliding window size sets the maximum number of unacknowledged frames. You can tune the size depending on the link status to maximize the throughput.
When sending a frame, Q.921 checks the number of unacknowledged frames. Suppose V(A) is the sequence number of the previous acknowledged frame, V(S) is the sequence number of the frame to be sent, and k is the sliding window size. If V(A) + k = V(S), the system stops sending frames.
Examples
# Set the sliding window size to 10 on ISDN PRI interface Serial 2/3/0:15.
<Sysname> system-view
[Sysname] controller e1 2/3/0
[Sysname-E1 2/3/0] using ce1

[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn pri-slipwnd-size 10
isdn progress-indicator
Use isdn progress-indicator to set the progress description in the progress indicator information element of ISDN signaling messages.
Use undo isdn progress-indicator to restore the default.
Syntax
isdn progress-indicator indicator
undo isdn progress-indicator
Default
ISDN uses the progress description assigned by the upper-layer voice service.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
indicator: Specifies one of the progress descriptions in Table 12.
Table 12 Progress descriptions
|
Value |
Description |
|
1 |
Call is not an end-to-end ISDN call. Further call progress information might be available in-band. |
|
2 |
Destination address is non-ISDN. |
|
3 |
Origination address is non-ISDN. |
|
4 |
Call has returned to the ISDN network. |
|
5 |
Interworking has occurred and has resulted in a telecommunication service change. For example, the ISDN network changes to the VoIP network. |
|
8 |
Signals of other protocols than ISDN are present on the D channel. |
Usage guidelines
The progress indicator information element describes an event that has occurred during the life of the call.
You only need to set the progress description manually only if you are required by the service provider to do so for compatibility.
Examples
# Set the progress description code to 8 on Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn progress-indicator 8
isdn progress-to-alerting enable
Use isdn progress-to-alerting enable to enable an ISDN interface to interpret the PROGRESS message as the ALERTING message.
Use undo isdn progress-to-alerting enable to disable an ISDN interface from interpreting the PROGRESS message as the ALERTING message.
Syntax
isdn progress-to-alerting enable
undo isdn progress-to-alerting enable
Default
The progress message is not interpreted as the ALERTING message.
Views
ISDN interface view
Predefined user roles
network-admin
Usage guidelines
Typically, ISDN devices use the ALERTING message to indicate that called user alerting has been initiated. To work with third-party ISDN devices that use the PROGRESS message to convey this information, you must execute the command.
Examples
# Interpret the PROGRESS message as the ALERTING message on ISDN PRI interface Serial 2/3/0:15.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn progress-to-alerting enable
isdn protocol-mode
Use isdn protocol-mode to configure the ISDN functionality of an ISDN interface.
Use undo isdn protocol-mode to restore the default.
Syntax
isdn protocol-mode { network | user }
undo isdn protocol-mode
Default
An ISDN interface provides the ISDN user-side functionality.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
network: Specifies the network-side functionality.
user: Specifies the user-side functionality.
Usage guidelines
An ISDN interface can provide the ISDN user-side or network-side functionality. For two ISDN devices to communicate with each other, you must configure one end as the network side and configure the other end as the user side.
You must configure the ISDN interface as the user side when ANSI, AT&T, ETSI, NI, or NTT is configured.
You cannot configure the command when a call is present on the ISDN interface.
Examples
# Configure Serial 2/3/0:15 as the network side.
<Sysname> system-view
[Sysname] interface serial 2/3/0:15
[Sysname-Serial2/3/0:15] isdn protocol-mode network
isdn protocol-type
Use isdn protocol-type to configure the ISDN switch type on an ISDN interface.
Use undo isdn protocol-type to restore the default.
Syntax
isdn protocol-type protocol
undo isdn protocol-type
Default
The ISDN switch type is DSS1 for PRI.
Views
ISDN interface view
Predefined user roles
network-admin
Parameters
protocol: Specifies an ISDN switch type. Available options include 5ess, ansi, at&t, dss1, etsi, ni, ni2, ntt, and qsig. To specify ANSI, AT&T, ETSI, NI, or NTT, make sure the interface is operating on the user side.
Usage guidelines
You can configure the command only when no call is present on the ISDN interface.
ISDN service providers in different countries implement variants of ISDN to provide varied ISDN services. When you configure an ISDN interface, you must set the switch type on the interface to be the same as the service provider switch type.
Table 13 shows the ISDN switch types available on an ISDN interface.
