Configuring ISDN Physical Interfaces with Quick Configuration

Physical Interface Description

(Optional) Adds supplemental information about the ISDN physical interface on the router.

Type a text description of the physical ISDN interface in the box to clearly identify it in monitoring displays.

Clocking

Enables internal or external clocking sources for the interface on the router.

• internal—Services Router's own system clock (the default)
• external—Clock received from the T1 interface

Select internal or external from the list.

Dialer Pools

Displays the list of configured ISDN dialer pools on the router.

• To add a dialer pool to the interface, click Add.
• To edit a dialer pool, select the name from the list. You can change the priority, but not the name.
• To delete a dialer pool, select the check box and click Delete.

Dialer Pool Name (required)

Specifies the group of physical interfaces to be used by the dialer interface.

Type the dialer pool name—for example, isdn-dialer-pool.

Priority

Specifies the priority of this interface within the dialer pool. Interfaces with a higher priority are the first to interact with the dialer interface.

1. Type a priority value from 0 (lowest) to 255 (highest). The default is 0.
2. Click OK to return to the Quick Configuration page.

Calling Number

Configures the dialing number used to connect with the service provider.

Type the outgoing calling number for the service provider.

ISDN Switch Type

Specifies the type of ISDN switch used by the service provider.

Select one of the following switch types:

• 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

Service Profile Identifier

Service Profile Identifier 2

Configures the service profile identifier (SPID) provided by your ISDN service.

Type the SPID in the box. If you have a NTDMS-100 or NI1 switch, an additional SPID field is provided.

Static TEI Value

Configures the static terminal endpoint identifier (TEI) value from your service provider.

The TEI number identifies a terminal endpoint, an ISDN-capable device attached to an ISDN network through an ISDN interface on the Services Router. The TEI is a number between 0 and 127. The numbers 0–63 are used for static TEI assignment, 64–126 are used for dynamic assignment, and 127 is used for group assignment.

Type a value between 0 and 63. If this value is not supplied, the router dynamically acquires a TEI.

If you configured more than one SPID, the TEI must be acquired dynamically.

TEI Option

Configures when the TEI negotiates with the ISDN provider.

• Select first-call to activate the connection when the call setup is sent to the ISDN provider.
• Select power-up (the default) to activate the connection when the router is powered on.

Timer T310 Value

Sets the Q.931 timer value in seconds.

Type a value between 1 and 65536. The default value is 10 seconds.
