CDM-710G High-Speed Satellite Modem Single G.703 (E3/T3/STS-1) Interface (CDI-10-1) Revision 1 MN-CDM710G For a table of the applicable interfaces and installable combinations, refer to Sect. 1.3.5 Allowable Data Interface Combinations. 12.2 Physical Description Figure 12-2 depicts the block diagram of the interface; Figure 12-3 shows the rear panel of the interface. The data interfaces provided here are as follows (left to right): • External Clock Input Port (J1) • The CDI-10-1 module provides a Single G.703 Interface Port – Rx / J2 (top) and Tx / J3 (bottom) – that is operable/selectable as E3, T3, STS-1 or OFF. Additionally, a Light-Emitting Diode (LED) labeled Active lights when G.703 data activity is sensed. Refer to the next section for connector information.
