Backup Modules

A backup connection protects a company's WAN operations against system
failure. Three types of backup modules are available for the ProCurve Secure
Router:
ISDN BRI S/T backup module for use outside of North America—supports
a 64 Kbps backup call or a bonded 128 Kbps call
ISDN BRI U backup module for use in the US and Canada—supports a 64
Kbps backup call or a bonded 128 Kbps call
VTU V.90 compliant analog modem—provides a connection speed of up
to 56 Kbps
Backup ISDN call bonding is currently a ProCurve proprietary technology. If
you bond your BRI backup call, your router can only place the call to another
ProCurve Secure Router.
With the ProCurve Secure Router, it is not necessary to devote an entire
module slot for a backup connection. Each module includes a backup inter-
face port. To activate the backup interface, you must purchase a separate
backup module and install it on top of the module, as shown in Figure 1-12.
