CDM-625A Advanced Satellite Modem
Introduction
1.3.2

Modem Compatibility

The CDM-625A is fully backwards-compatible with the Comtech EF Data CDM-625, CDM-500,
CDM-550, and CDM-550T modems. As an Open Network Modem, the CDM-625A is fully
compatible with modems from other manufacturers that are compliant with the IESS-
308/309/310/314 specifications. Note, however, that IESS-315 (VSAT Turbo) defines closed
network operation, and this therefore requires modems from the same manufacturer at both
ends of the link.
The unit is also fully backwards-compatible with the CDM-600 and CDM-600L modems (with the
exception of a lower data rate range of 18 kbps). The modem includes software emulation of
CDM-600 and CDM-600L.
