Alcatel - Lucent MDR-8000 CommPak Low Profile Shelf 
The
MDR-8000 CommPak is a reduced-size package for non-standby radio
configurations. It is applicable to the entire product line,
covering all frequency bands and all capacities of the MDR-8000
family. In addition to its greater space efficiency, the CommPak
offers solutions for both indoor and outdoor installations.
Many network architectures do not require the built-in 1+1 equipment
redundancy of the standard MDR-8000 shelf. Low-density microwave
routes with less than 8 T1 are commonly equipped with 1+0 protection.
Also, when radio is used for back up to other wireline facilities,
redundancy of the radio electronics is not required. Even highly
secure networks that utilize ring protection switching don't require
redundant radio electronics since the circuit multiplexers, not
the radio link, provide the service protection. The low profile,
MDR-8000 CommPak is ideal for these applications.
Additionally, network operators are increasingly finding the need
to locate radio equipment at sites that lack space for traditional
indoor installations. The MDR-8000 offers an ideal solution for
such situations with a pole mountable outdoor enclosure.
