Paradyne DMD15L Turbo Codec, Drop and Insert D&I, 5 8PSK Modulation, Oqpsk Modulation

Introduction DMD15/DMD15L IBS/IDR Satellite Modem

1.1.3 Turbo Codec

The DMD15/DMD15L can be equipped with an optional Turbo Codec Outer Code. This option must be installed at the factory.

1.1.4 Drop and Insert (D&I)

The DMD15/DMD15L can be equipped with a D&I Interface as an add-on enhancement. This option can be added in the field by installing one IC into an existing socket. The D&I Functions are completely independent and can be programmed for n x 64 blocks for either a T1 or E1 Data Stream.

1.1.5 8PSK Modulation

The DMD15/DMD15L can be equipped with 8PSK Modulation/Demodulation capability as an add- on option. The 8PSK Option can be added by installing 2 ICs into existing sockets.

1.1.6 OQPSK Modulation

The DMD15/DMD15L can be equipped with an OQPSK modulation/demodulation capability as an add-on option. The option can be added in the field by installing one IC into an existing socket.

1.1.7 16QAM Modulation

The DMD15/DMD15L can be equipped with a 16QAM Modulation/Demodulation capability as an add-on option. The 16QAM option can be added by installing 2 ICs into existing sockets.

1.1.8 Sequential Decoding

The DMD15/DMD15L can be equipped with a sequential decoding option that can be installed as an add-on option. The DMD15/DMD15L must be prepped for this option in the factory. Once prepped, the option can be added by installing 3 ICs into existing sockets. Sequential Encoding/Decoding can operate with 1/2, 3/4, and 7/8 Rates, up to data rates of 2.048 Mbps.

1.1.9 Earth Station-to-Earth Station (ES-ES) Communications

The DMD15/DMD15L can be equipped with an asynchronous overhead channel capability as an add-on option. The option can be added in the field by installing 2 ICs into existing sockets. The overhead channel is proportional to the data rate (2,400 baud per 64 KB) up to a maximum of 19.2 Kbaud.

1.1.10 Analog AGC Voltage

The DMD15/DMD15L can be equipped at the factory to produce an analog voltage equivalent to its AGC for use in antenna controllers.

1.1.11 Internal Engineering Service Channel (ESC)

The DMD15/DMD15L can be equipped with an internal ESC. This unit is a card on the Universal Interface Module (UIM). The DMD15/DMD15L can be updated with an ESC capable UIM in the field with no other changes required.

1.1.12 OM73 Compatible
