Multilet access system MAS-64

SystemMAS-64MIO-04ConnectionAttenuation3 MASUPSBandwithReturn Amp.QoSMIO-04System lossSpeedDownstreamUpstreamDefaultPreparationsCalculationsRanagerConfig IO

  • Access switch, CMTS, for up to 64 users.
  • Extra outlet for every connected user.
  • Not connected users are not affected
  • Frequency 5 – 36 MHz for upstream
  • Frequency 64 – 76 MHz for downstream
  • Use existing coax installation, no upgrade to network required.
  • Build VLAN between users
  • Range up to 5 km between MAS and MIO

Don´t use ch.4 and down-stream lower then 70 Mhz

Bandwith of the upstream is 3.8 MHz as default

Bandwith of the downstream is 3,5 MHz as default

You will loose ~ 1dB in forward and ~ 1dB

in return by using 2 diplex-filter.

QoS

SystemMAS-64MIO-04ConnectionAttenuation3 MASUPSBandwithReturn Amp.QoSMIO-04System lossSpeedDownstreamUpstreamDefaultPreparationsCalculationsRanagerConfig IO

  • With Macab MTR-serie (traffic-shaper) you will be able to:
  • Control the bandwith to each user from 128 Kb/s up to 10 Mbit/s
  • Login- / User authentification System
  • VoIP (priority)
  • Advanced logg-functions

Transfer Speed

  • Download speed (3 Msymb. & QAM64) 7 Mbps
  • Upload speed (3 Msymb. & QPSK) 3 Mbps
  • Data rate MAS System Downstream 18* Mbps
  • Data rate MAS System Upstream 6* Mbps

Notice! 8 bit = 1 byte

240 kB/s in downloadspeed is equal to a Internetspeed of 2 Mbit/s

preparations
Measure the forward and return path frequency response

Chose forward and return path that gives the best performance regarding loss, noise and interference

Measure the TV channels levels to check the system performance before Multilet installation

If you need to upgrade the system do this before Multilet installation

Preparations

SystemMAS-64MIO-04ConnectionAttenuation3 MASUPSBandwithReturn Amp.QoSMIO-04System lossSpeedDownstreamUpstreamDefaultPreparationsCalculationsRanagerConfig IO

system calculations
Keep same level of downstream signal as the TV channels. Min level to MIO 63 dBuV.

Calculate the return attenuation as a normal TV channel. Max transmission level of MIO is 108 dBuV. Min input level to MAS is 63 dBuV.

Do not FORGET to include a margin.
