Configuring Backup WAN Connections
Configuring a Persistent Backup Connection
For example, you might enter:
ProCurve(config-bri 1/2)# isdn ldn1 5555551111
You can also set a secondary LDN using the isdn ldn2 command:
ProCurve(config-bri 1/1)# isdn ldn2 5555552222
If you are configuring an ISDN line in North America, you may also need to
define a SPID. As described in the next section, you can set the SPID at the
same time that you set the LDN.
Setting the SPID and LDN (North America). Some North American tel-
cos, principally those that use the DMS-100 and National ISDN-1 switches,
issue SPIDs. A SPID is typically a 14-digit number that includes the BRI
interface's 10-digit phone number and several identifiers. These identifiers
specify the type of service on the line, indicating that the interface accepts
data rather than voice.
Even though the SPID typically includes the LDN, you must specify the LDN
separately after the SPID if you want the interface to answer calls. Enter the
following command:
Syntax: isdn spid1 <SPID> <LDN>
Enter the LDN that your public carrier provides. For example:
ProCurve(config-bri 1/3)# isdn spid1 70455511110101 5555551111
Some telcos assign two SPIDs to ISDN connections that use both channels.
You must set the second SPID and LDN in order for the second B channel to
properly receive data. You set the SPID and LDN using the isdn spid2
command:
Syntax: isdn spid2 <SPID2> <LDN2>
Activating the Interface. The BRI interface must be manually activated.
From the BRI interface configuration mode context, enter:
Syntax: no shutdown
You can check the status of the interface by entering:
Syntax: do show int bri <slot>/<port>
The status should be "ready." The report will also show you the settings you
have entered for signaling, SPID, and LDN. (See Figure 3-13.)
