128tcm

Hallo
I am interested to receive a link in 4GHz band 155Mb/s 128TCM 29MHz band.
I see that some manufacturer made these items:it is impossible to buy for a student or amateur ,not for money(no problem) but for the reason I am not a broadcaster.This items should be very useful for my studies and I need only one piece or two.
Someone can help me?(e.g Siemens srt1 or Nera)

SDH equipment like one you want are under strict control of government organisations in all countries. If you realy have enough money to spend on such peace of equipment you can try to find if some distributor of following companies in your neighbourhood: Ericsson, Alcatel, NEC, Harris, DMC, some old BOSCH, Teletra or Marconi. They all manufacture or have manufactured devices with TCM schemes (64-512) im MW bands.
On the other hand, cheaper and more efficient way of learning would be to try to find a job in a telecom company with large point-to-point network.
