PROMAX-27 is an analyzer for the installation and maintenance of
video and high speed data interactive services over TV networks based on the
EuroDOCSIS and DOCSIS 2.0 standard. It allows the qualification of VoIP and IPTV
services and it includes several test modes such as the TILT function that
allows equalization of the line. |
|
|
VoIP VoIP (voice over IP) or IP Telephony, is a group of resources that make it possible for the voice signal to travelover the Internet using IP (Internet Protocol). The PROMAX-27VoIPfunction performs an analysis of the network based on the quality of service parameters, named UGS, according to the standards DOCSIS / EuroDOCSIS. The PROMAX-27analyses the most important factors that may affect the quality of communication, including latency, jitter, lost packets, MOS and R value. This comprehensive analysis will ensure the achievement of an excellent quality of call. |

IPTV Service Analysis Internet Protocol Television (IPTV) has become the most common denomination for the distribution systems of television and / or video signals using IP on a network infrastructurePROMAX-27analyses parameters than can affect quality signal, like latency, jitter, lost packets and trace route, which trace the route of sent packets on a graph. This will be useful to detect possible bottlenecks |

TILT function The TILT test is an utility to equalize the line. For that, it is used two pilot signals that are transmitted normally at the beginning and end of the CAT network band. These two pilots are the ones that can be tuned simultaneously on the screen. By this way you can evaluate the losses slope and therefore readjust equalizers of amplifiers in order to compensate these losses and ensure a flat response across the band. |

Packet Loss Ratio When the PROMAX-27operates in registered mode, it can communicate in the network and can show useful data related to the IP addresses allocation and the form in which the packets flow throughout the network. The instrument calculates the ratio of packages received (PLR) which represents a statistical measurement about the traffic effectiveness through the network, as well as the maximum and minimum times for those receptions. This will allow to evaluate the network capability to support certain transport services (e.g. voice on IP) and to determine the global performance of the overall system. |
|
|
Upstream and Downstream The PROMAX-27communicates with the CMTS and shows the most important information related to the transmission: frequencies assigned in the upstream and downstream, signal quality in the downstream (power, BER, MER), power transmitted by the modem and attenuation in the return band. The upstream attenuation is a very important parameter and the installer must verify if this parameter is within the specified range. |

MER and Constellation These measurements are decisive for the early detection of excessive noise in the system or intermodulation problems in the downstream. In general, a lower MER can mean system operating problems, as well as a slow speed due to the packets loss and interruptions. The display of the constellation diagram and the bit error rate (BER) are other key measurements to evaluate the performance of the downstream. |

Spectrum Analysis When in Scan mode all the carriers or a portion of them are displayed in the screen. When the tuned channel is zoomed, it shows in one screen the channel under test, both adjacent channels and the level measurement. It is extremely useful to view interference's at a glance. |
