User InterfacesDMD15/DMD15L IBS/IDR Satellite Modem

Remote AUPC (menu):

The 'REMOTE AUPC CONFIGURATION' menu contains

 

the remote configuration parameters for the AUPC

 

Function.

AUPC Enable:

{OFF, ON}

 

Allows the user to enable or disable the AUPC Function

 

of the remote modem. The remote AUPC Function is

 

the response of the local modem to commands for an

 

increase or decrease of the Transmit Power in 0.5 dB

 

steps and the command to change to the setting

 

indicated in the 'REMOTE CL ACTION' menu of the

 

remote modem upon receiver loss of lock.

Loopback:

Allows the user to enable or disable the Baseband

 

 

Loopback Test Mode of the remote modem.

TX 2047 Pattern:

Allows the user to enable or disable the Transmit 2047

 

 

Pattern Test Mode of the remote modem.

Remote AUPC Monitor:

The ‘REMOTE AUPC MONITOR’ Menu contains the

 

remote monitor status for the AUPC Function.

Remote 2047 BER:

Reports the BER measurement of the receiver 2047

 

Pattern Test Mode of the remote modem. BER is

 

reported from the 1x10-5to 1x10-7in tenth decade steps.

 

If the pattern does not synchronize or is out of range,

 

‘NO DATA’ will be displayed.

4.3.6 Monitor Menu Options and Parameters

Level:

Displays the estimated receive signal level as seen by

 

the Demodulator.

Eb/No:

Displays the estimated Eb/No as seen by the

 

demodulator.

SER:

Displays the estimated channel error rate (before

 

decoding) measured by the modem.

CBER:

Displays the estimated corrected bit error rate (after

 

decoding).

Error Count:

Displays the current error count from the Viterbi

 

Decoder.

Offset Freq:

Displays the received carrier frequency offset as

 

measured by the modem.

DMD15, DMD15L specifications

The Paradyne DMD15L and DMD15 are advanced digital modems designed to enhance communication in a variety of networking environments. As part of Paradyne's robust portfolio of networking solutions, these devices are engineered to deliver reliable and efficient data transmission over both copper and fiber optic connections.

One of the main features of the DMD15L and DMD15 is their capability to support Multiple Protocol Data Units (MPDUs), which enables them to handle a diverse range of network protocols seamlessly. This flexibility makes them suitable for different applications, from industrial automation to telecommunications.

These modems utilize advanced modulation techniques, such as Quadrature Amplitude Modulation (QAM), to maximize data throughput while maintaining signal integrity. This ensures that users benefit from high-speed connections, even in challenging signal environments. Furthermore, the DMD15 series incorporates Error Correction Codes (ECC) that enhance data reliability, effectively reducing packet loss and ensuring data coherence during transmission.

The DMD15L is particularly notable for its long-range capabilities, making it a go-to solution for users requiring extended distances without compromising data quality. It features built-in Adaptive Equalization, which automatically adjusts signal levels to optimize performance over varying transmission distances. This technology is crucial in maintaining consistent high-speed connectivity, especially in environments with variable conditions.

Both models are equipped with user-friendly interfaces that facilitate configuration and management. They support SNMP (Simple Network Management Protocol) for real-time network monitoring, allowing administrators to track performance metrics and identify potential issues before they impact users. The devices also include LED indicators for quick status checks, ensuring that users have immediate visibility of operational conditions.

In terms of physical characteristics, the DMD15 and DMD15L are designed for durability and ease of installation. They come in a compact form factor, making them suitable for deployment in constrained spaces. Additionally, their robust casing is built to withstand harsh environmental conditions, making them suitable for both indoor and outdoor installations.

Overall, the Paradyne DMD15L and DMD15 are high-performance modems that combine versatile technologies, reliability, and user-friendly features. They are excellent choices for organizations looking to enhance their communication capabilities and ensure robust data transmission across diverse networks. With their advanced functionalities and adaptability, these modems stand out as key components in modern network infrastructure.
