Verilink PRISM 4101 (34-00230) Product Manual - Manual (Page 14)

2 C HAPTER 1: G ENERAL
The dial backup feature ensures that critical data applications are secure. The
dedicated line service is monitored for trouble conditions. When a line failure is
detected, the unit establishes a dial connection through a backup port. Once the
backup link is up, the unit routes the customer data through the switched service.
When dedicated line service is restored, the unit automatically reverts back. The
dial backup port allows you to use any type of external switched service simply by
choosing a modem or ISDN unit for dial backup. The PRISM 4101 may also be
ordered with an internal 33.6 baud modem.
