Regarding the combination of PBI DMM1000 and Cisco 3750G

May 6, 2014   Author: Ma Hailong

1. Question:

In the actual project, we encountered the PBI DMM1000P chassis, which is internally configured with QAM demodulation cards and encoding cards. The QAM demodulation cards and encoding cards output IP multicast to the Cisco switch 3750. After the DMM1000P chassis loses power and restarts, there is no output from the QAM demodulation cards and encoding cards.

2. Solution:

The Harley bNSG 9000 IPQAM supports a maximum of 54 RF outputs. Configuration of the device is done via a web browser. Before configuring, it is necessary to confirm the device's management IP address, which will be displayed on the device's LCD screen. You can also query or change the device's IP address. Once the IP is set, you can manage it through a web browser.

CCAP and the full IP NSGPro provide a simple and flexible path as a converged wired access platform (CCAP), offering high-density universal edge QAM capabilities and a straightforward upgrade path for future integrated CMTS functionality. The 9-RU NSGPro boasts industry-leading density, integrating broadcast video, video on demand, and data into a single system, minimizing costs; whether today or as operators expand their IP infrastructure.

Harley NSG9000 Board 36R1G

NSG 36R1GThis is a QAM RF module used in the high-density Harley Company NSG™9000 universal edge QAM platform. The module has two RF ports, each capable of outputting 36 QAMs (ITU-T J.83 ANEX B / C) or 27 QAMs (ITU-T J.83 ANEX A). The configuration of the RF output ports is highly flexible, allowing for the maximum number of QAMs, with the frequency positions of the QAMs set within a 384MHz block for each port.

Harley NSG9000 RF Module 8R1G

The NSG 8R1G is a QAM RF module used in the high-density Harmonic NSG™9000 universal edge QAM platform. This module features two RF ports, each capable of outputting 1 to 8 QAMs (ITU-T J.83 ANNEX B / C) or 6 QAMs (ITU-T J.83 ANNEX A). The configuration of the RF output ports is highly flexible, allowing for the maximum number of QAMs, with the frequency positions of the QAMs set within a 48MHz block for each port.
