VB262 CABLE QAM ITU.T J-83 ANNEX A/B/C RF INPUT

The VB262 DUAL QAM/8VSB input option offers monitoring of cable TV signals as found in ITU-T J.83 Annex A/B/C QAM networks and DTT signals found in 8VSB networks. A chassis can be equipped with a VB120 or VB220 PROBE controller that has one or two VB262 RF input cards under its control.

Figure - The 1RU Enhanced Chassis populated with one VB120 controller module and two
VB262 QAM/8VSB input modules.


A complete configuration with a fully licensed VB120 provides real-time monitoring and alarming for four QAM or VSB RF inputs, 50 IP MPTS/SPTS multicasts, upgradeable in steps of 10 from an initial 10 streams, and a ASI TS input and output.

ETSI TR 101 290 analysis is performed in parallel for the QAM/8VSB inputs, the ASI input and the IP input. If the VB220 is used as master card the IP monitoring capacity is increased to impressive 260 MPTS/SPTS multicasts in addition to the RF inputs.

The combined unit is ideal for hybrid networks where IP is used as a carrier from head-end to the regional edge multiplexer/ modulator/ transmitter. The built-in round-robin functionality allows sequential analysis of multiple QAM or VSB multiplexes, making it possible to monitor the total broadcast contents of a cable transmission system using a single VB262.

Each RF input port can be programmed to scan through 50 individual frequencies in a round-robin fashion.
