Redundancy Features Overview
The CTP series provides the following
redundancy features:
- Ethernet interface failover—If the default Ethernet
interface fails, the CTP device fails over to the next unconfigured
Ethernet interface.
- Route management redundancy—If the next-hop gateway
(the router) becomes unreachable, the CTP device uses configured static
routes to a next-hop gateway on a different network.
- Bundle failover between CTP devices at alternate sites—If
a bundle circuit fails and the CTP device becomes unreachable, the
CTP device fails over to a CTP device at an alternate site.
- Bundle failover between CTP devices at the same site—If
a bundle circuit fails and the CTP device becomes unreachable, the
CTP device fails over to a redundant CTP device that is connected
to the failed device by a Y cable.
- Bundle failover between CTP devices at both the local
and remote sites—If a bundle circuit fails and a CTP device
at either the local or remote site becomes unreachable, the CTP devices
fail over to bundles configured on the redundant CTP devices. At each
site, two CTP devices are connected to the customer equipment with
a Y cable.
- Packet redundancy—If packets are lost because of
transmission errors, the packet protector feature can enable a possible
recovery scenario.
