Adding an ISDN Interface (Required)

Task

J-Web Configuration Editor

CLI Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy.

1. In the configuration editor hierarchy, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Configure or Edit.

From the top of the command hierarchy, enter

edit interfaces br-1/0/3

Create the new interface—for example, br-1/0/3.

1. Next to Interface, click Add new entry.
2. In the Interface name box, type the name of the new interface, br-1/0/3.
3. Click OK.

Configure dialer options.

• Name the dialer pool—for example, ISDN-dialer-group.
• Set the dialer pool priority—for example, 25.

Dialer pool priority has a range from 0 to 255 with 0 designating lowest-priority interfaces and 255 designating the highest-priority interfaces.

1. In the Encapsulation column, next to the new interface, click Edit.
2. Next to Dialer options, select Yes, and then click Edit.
3. Next to Pool, click Add new entry.
4. In the Pool identifier box, type isdn-dialer-group.
5. In the Priority box, type 25.
6. Click OK.

From the [edit interfaces br-1/0/3] hierarchy, enter

set dialer-options pool ISDN-dialer-group priority 25

Configure ISDN properties.

• Calling number of your ISDN provider—for example, 18005555555.
• Service provider ID (SPID)—for example, 00108005555555.
• Static TEI between 0 and 63 from your service provider—for example, 23. If the field is left blank, the Services Router dynamically acquires a TEI.

If you have a NTDMS-100 or NI1 switch, an additional box for a service provider ID is provided.

If you are using a service provider that requires SPIDs, you cannot place calls until the interface sends a valid, assigned SPID to the service provider when accessing the ISDN connection.

1. Next to Isdn options, click Configure.
2. In the Calling number box, type 18005555555.
3. In the Spid1 box, type 00108005555555.
4. In the Static tei val box, type 23.

1. To set the ISDN options, enter

   set isdn-options calling-number 18005555555

2. Enter

   set isdn-options spid1 00108005555555

3. Enter

   set isdn-options static-tei-value 23

Select the type of ISDN switch—for example, att5e. The following switches are compatible with Services Routers:

• att5e—AT&T 5ESS
• etsi—NET3 for the UK and Europe
• ni1—National ISDN-1
• ntdms-100—Northern Telecom DMS-100
• ntt—NTT Group switch for Japan

From the Switch type list, select att5e.

To select the switch type, enter

set isdn-options switch-type att5e

Configure Q.931 timers. Q.931 is a Layer 3 protocol for the setup and termination of connections. The default value for each timer is 10 seconds, but can be configured between 1 and 65536 seconds—for example, 15.

1. In the T306 box, type 15.
2. In the T310 box, type 15.

1. Enter

   set isdn-options t306 15

2. Enter

   set isdn-options t310 15

Configure when the TEI negotiates with the ISDN provider.

• first-call—Activation does not occur until a call is sent.
• power-up—Activation occurs when the Services Router is powered on. This is the default value.

1. From the Tei option list, select power-up.
2. Click OK to return to the Interfaces page.

To initiate activation at power-up, enter

set isdn-options tei-option power-up
