Check the Network LEDs. Is the Sig (signal) LED on, and are the OOF (out of
frame), and ALM (alarm) LEDs off?
– If yes, the network interface is set up correctly and is ready to pass data.
– If no, check that both ends of the network cable are properly seated, then verify
that the network physical options are configured correctly.

Setting Up the ISDN DBM
FrameSaver 9126 and 9128 units may be equipped with an ISDN DBM.
An ISDN BRI DBM may be installed in a FrameSaver 9126, supporting up to
2 B-channels.
An ISDN PRI DBM may be installed in a FrameSaver 9128, supporting up to
23 B-channels.
The following guidelines apply.
Central site configuration guidelines:
– Configure a Link Profile for each remote site.
– Configure the unit to answer calls from the remote sites.
– Leave Automatic Backup Configuration disabled.
– Manually create alternate DLCIs on the ISDN Backup Link.
– Manually specify ISDN DLCIs as alternate DLCIs for the PVC Connection after
the primary DLCIs have been automatically discovered from the primary network
Link LMI or manually configured.
Remote site configuration guidelines:
– Configure a Link Profile for the central site in the first link profile, called HQ_Site.
This ensures that a backup DLCI will be created automatically on the backup
link for each DLCI discovered on the network interface using the central site’s
link profile.
– Configure the unit to originate calls to the central site if it is a FrameSaver 9128.
A FrameSaver 9126 is already configured to originate calls.
– Enable the Automatic Backup Configuration feature if the unit is a
FrameSaver 9128. A FrameSaver 9126 already has this feature enabled.
