CDM-710G High-Speed Satellite Modem
Introduction
control, although it can be fully remote-controlled via its RS-485 bus or 10/100 Base-T Ethernet
Interface.
1.1.1

Standard and Optional Features

The CDM-710G operates in DVB-S2 (QPSK, 8PSK, 16APSK, and 32APSK) mode only. The
CDM-710G is operated from the front panel using the keypad and display or remote controlled
via an RS-232 / RS-485 2/4 Wire bus or 10/100 Base-T Ethernet port located on the base unit.
The CDM-710G is available for either 70/140 MHz or L-Band applications. The standard 70/140
MHz Tx-IF port has a BNC female connector that is programmable for either with 50Ω or 75Ω
impedance operations. Spectral rolloffs of 20, 25, and 35% are available.
1.1.2

Applications

The CDM-710G's bandwidth and power-efficient operation is ideal for:
Transmission of non-transport stream data (referred to as Generic Data in DVB-S2)
Business enterprise data distribution
Broadband Interactive and Internet services
Any networking application relying on
o Point-to-point transmission
o Point-to-multipoint transmission
o Arbitrary topology
With a Gigabit Ethernet (GigE) data interface and either a 70/140 MHz (CDM-710G) or L-Band
(CDM-710GL) IF, the CDM-710G is equipped with the configuration most frequently requested
by users. This is ideal for data transmission formats that take advantage of the Ethernet packets
for digital one-way, two-way and any network applications. The HSSI interface enables IP or
other data formats via a serial interface, and telecom applications are supported with the G.703
interface.
performance. Whether a link is point-to-point or point-to-multipoint, there is a format available to
suit each application.
