Redundancy / Mute - PEAK COMMUNICATIONS DBUH Series Installation And Operating Handbook

REDUNDANCY / MUTE

The redundancy option allows the user to select which tray is online, either A or B. Alternatively,
Auto mode can be selected, allowing the automatic switching in/out of faulty trays.
If the unit also has the mute option fitted, then the output of the redundancy system can be
muted via one of the unit's user interfaces e.g. menu.
Where the DBUH/ DLAH/ DTLH is purchased as a redundant system with two identical MBUH/
MBDH/ MLAH/ MTLH modules, the rear panel cabling configuration is shown below.
The customer is required to supply the system input and output cables. Peak Communications
will supply the interconnecting cables unless instructed otherwise.
