Service Profile Identifications (SPIDs)

SPIDs identify the services and features that the switch provides to the

ISDN device.  Commonly implemented in the U.S. and Canada, the

SPID is often derived from the directory number, concatenated with other

digits.

Note:  SPIDs are not implemented outside North America.

Refer to Chapter 1, ISDN and Ordering Issues, for further information.

TCP/IP Routing Entries

You will need to obtain the following network addresses:

For the Ethernet Interface

Ethernet IP Address (Local LAN)

An Ethernet LAN IP address and subnet mask are required for the

router’s local Ethernet LAN connection.

TCP/IP Ethernet Routes

You normally do not need to define an Ethernet IP route. An Ethernet IP

route consists of an IP address, a mask, a metric, and a gateway. An

Ethernet route is usually defined when there are multiple routers on the

Ethernet, which cannot exchange routing information between them.

Ethernet Default Gateway

One default route should be designated in the routing table for all traffic

that cannot be directed to other specific routes.

You will need to define the default route to a remote router or define an

Ethernet gateway. There can be only one default route specified for all

the remote database entries.

For the ISDN WAN Interface

Source (Target/Local) WAN Port Address

You may need to specify a source WAN IP address for the WAN

connection to the remote router depending on IP address negotiation

under PPP.

Check with your system administrator for details on whether the router

must communicate in numbered or unnumbered mode and what

addresses are required.  The router is set to unnumbered mode by default.

This enables numbered mode on the WAN interface.
