Set Up Redundancy
Redundant hardware can enable your modem connection to remain operational even if one part of the
physical links fails. Two pairs of 2345 modems provide full redundancy or a pair of modems with
dual-path OLIMs provide optical redundancy. To ensure redundant operation in all circumstances,
also enable Switchover on bad SQL.
