Chapter 4 Edit Interface/Connection

Connection: ISDN BRI

Some service providers use SPIDs to define the services subscribed to by the

ISDN device that is accessing the ISDN service provider. The service provider

assigns the ISDN device one or more SPIDs when you first subscribe to the

service. If you are using a service provider that requires SPIDs, your ISDN device

cannot place or receive calls until it sends a valid, assigned SPID to the service

provider when accessing the switch to initialize the connection.

Currently, only the DMS-100 and NI switch types require SPIDs. The AT&T

5ESS switch type may support a SPID, but we recommend that you set up that

ISDN service without SPIDs. In addition, SPIDs have significance at the local

access ISDN interface only. Remote routers never receive the SPID.

A SPID is usually a seven-digit telephone number with some optional numbers.

However, service providers may use different numbering schemes. For the

DMS-100 switch type, two SPIDs are assigned, one for each B channel.

Remote Phone Number

Enter the phone number of the destination of the ISDN connection.

Options

Click this button if you need to associate ACLs with a dialer list to identify

interesting traffic, enter timer settings, or enable or disable multilink PPP.

Identifying interesting traffic will cause the router to dial out and create an active

connection only when the router detects interesting traffic.

Timer settings will cause the router to automatically disconnect a call after the

line is idle for the specified amount of time.

Multilink PPP can be configured to provide load balancing between ISDN B

channels.

IP Address

Select either Static IP address, IP Unnumbered or IP Negotiated. If you select

Specify an IP address, complete the fields below.

IP Address

Enter the IP address for this point-to-point subinterface. Obtain this value from

your network administrator or service provider. For more information, refer to IP

Addresses and Subnet Masks.
