About this Manual


This manual provides installation and operation information for the Comtech EF Data
CDM-570 and CDM-570L satellite modems with optional IP Module. These two

70/140MHz IF band, whereas the CDM-570L operates at L-band, and includes support
for externally connected BUCs and LNBs. This is a technical document intended for
earth station engineers, technicians, and operators responsible for the operation and
maintenance of the CDM-570/570L with optional IP Module.
