Hello!
I'm working on the BreezMAX 3500 system. For increasing traffic capacity 3 of 4 AU cards were changed on cards with BW=7 MHz. 4-th card remained unchanged, BW-3.5 MHz. About 6 month it works with no problem. But at last month clients, which connected on 4-th sector, were work very bad. If one of this clients start use his canal - all clients of this sector have very bad ping with 4 and more loses and great time of delay. All of radio params at this moment remain unchanged with good level. Replacement AU card on another with BW 3.5 MHz (AU with 7 I no have)) with change no. of slot, change ODU - doesn't take any effect. Using rules with RT QoS Profile also did not bring a good result. But CG QoS Profile - take "smooth" ping and good quality. But I can't provide to this client's speed over than 2.5 Mbit/s and CG QoS Profile consumes much of radio resources.
Help please. With which it can be connected?
