Frequency-divided Addressable Access Controller JT Series

Feature

Aggregative indicator is better than JH series products, adopts the circuit and construction advantage of JH series;

Frequency-divided control, could implement frequency band limited open via port, also called three-state

access-controller.The different frequency-divided methods are as following:

A) JTx8xxxA(B)xlx series: 300MHz high-pass filter (5～250MHz off, 300～860MHz on). The main function is to develop

the value-added service through power off upstream channel and limit the program;

B) JTx8xxxA(B)x2x series: 87MHz high-pass filter (5～65MHz off, 87～860MHz on). By controlling the upstream (on or off),

it can reduce the upstream influx interference greatly in two-way HFC network and improve the network security;

c) JTx8xxxA(B)x3x series: 550MHz low-pass filter (600～860MHz off, 5～550MHz on). The main function is to develop the

increment TV frequency service through power-off upstream channel and limit the program;

D) JTx8xxxA(B)x4x series: 87～550MHz band-pass filter (5～65MHz off, 600～860MHz off, 87～550MHz on). By

controlling the upstream (on or off), it can reduce the upstream influx interference greatly in two-way HFC

network and improve the network security. At the same time, it can develop the value-added service through

power off upstream channel and limit the program

Independent filter is used in each port of a terminal-controller to realize the frequency-divided controlling. Low insertion

loss and good C/CTB、C/CSO;

High port isolation, low interference, which enable more value-added service;

Upgraded online for two-way reserved/network management reserved products without needs to debug, which

can reduce the initial investment

Various network management function (see NE130X access controller network management responder).
