The transition to the backup

SCE 1000

platform is transparent. Once the routers/switches detected

that traffic has been cut, they start sending traffic through the redundant link. After this occurs, the
failed

SCE 1000

can be fixed/replaced with no downtime, since the box is effectively

disconnected from the network. After fixing/replacing the failed

SCE 1000

, you must copy the

configuration of the current active

SCE 1000

to the fixed/replaced

SCE 1000

The backup and restore procedures used for copying policies and Service Configurations from
one

SCE 1000

to the next are detailed in the

Service Control Application Suite for Broadband

User Guide

Failure and Recovery

It is important to decide how the system should behave in case of the failure of the

SCE 1000

both during the time that the unit is down and after recovery. This decision is influenced by
several factors:

•

Physical installation (connection mode)

•

Redundancy

•

Relative importance of maintaining connectivity vs. the continuity of the value-added services
that the

SCE 1000

enables.

Physical Installation

In a link connection via an external optical splitter,

SCE 1000

failure does not affect traffic flow,

which continues through the external optical splitter. When the

SCE 1000

detects a failure that

requires a recover by reboot, it immediately switches to Cutoff mode, stopping all traffic flow
over the link until the

SCE 1000

unit is restored to operation.

When operation resumes, the defined operational bypass mode is automatically resumed.

The configuration of a bump-in-the-wire installation depends on the remaining two factors.

Redundancy

Redundancy requires two platforms on parallel links, one active and one standby, in inline
topology. When the active

SCE 1000

platform detects a failure situation, it will immediately

switch to Cutoff mode, causing the routers/switches on both ends to switch the traffic to the
standby link and thus activate the standby

SCE 1000

platform.

There are two options when the failed

SCE 1000

platform is finished reloading:

•

It may either actually resume operation in the defined operational bypass mode, returning to
its status as the active

SCE 1000

platform.

•

It may remain inactive in the failure bypass mode.
