Hardware Overview

Note 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.

Each backup module can be used to back up any WAN connection on the

router, no matter where the backup module is housed.

Wide-Slot Option Modules

The ProCurve Secure Router 7203dl includes a third, wide-module slot.

ProCurve offers an eight-port E1/T1 module and an eight-port serial module.

(See Figure 1-14 and Figure 1-15.) The E1/T1 module supports both E1 and T1

formats and can be toggled between the two. The toggle switch is located on

the top of the module. Set the switch to ON for E1 format; set the switch to 1

for T1 format. Figure 1-13 shows the location of the toggle switch on the

module.
