MA1200 Add-on
The MobileAccess1200 Add-On module is used to provide support for an additional service to an
MA 2000 RU. The host MA2000 RU and the MA1200 Add-On are interconnected and either
housed in a MA2000 Cabinet or connected externally to a MA2000-Lite ‘enclosure’.
MA1200 Add-On provides the following functions:
•
Single service – either low-band or high-band
•
Installed only as an addition to a MA2000 RU
NOTE: MA1200 add-on does NOT interface directly to the fiber optic infrastructure, does not perform the
optic to RF conversion and does not interface to the antennas. All these functions are provided by the host
MA2000 RU unit.
