Title: Speedcast After Upgrade ??? Help Post by ninjaturtle on Apr 29th, 2007 at 3:43am
Hallo,
At 21 April 2007, Speedcast KU-Band (PAS12) had upgraded the RCST (Linkstar) to the new version like below: lmep 0xXXXXX SW rcst4-1.0.8.16p8.term.exe () rcst4s-2.2.0011.term.exe (PE) 0xXXXXX FW rcst4.16100106L.xilinx.dat () rcst4.15250706L.xilinx.dat (PE) After upgrade done, my RxPower decreased about 4 value (before -46 and after -50). Also, my upload speed decreased 30-50%. Please confirm if there are other people have same problem like me. FYI, here my TCMP result after upgrade: tcmp RSCorrectedErrorCount 0 RSUncorrectedErrorCount 0 QPSKBER 0.00005333591 I2CErrorCount 0 LostSyncCount 0 TimeSynced 4347 MaxTimeSynced 4347 Synced 1 TimeUnSynced 54 NCODeviation 0 CarrDeviation 0.002660821 VCOLocked 0 CodeRate 3/4 CarrierPhase LOCKED RSVit LOCKED UCActive NOT ACTIVE Rs 4.073489 Fs 60 frequency 1416 UCLoaded 1 RxPower -50.14016 RSFrameLength 700168018 BER 0.00005333591 Thanks. |

Anybody ??
Please give me information for this issue. After upgrade, my BER never got 0. Anybody have same issue ? |

Raw BER rates like 0.00005 are excellent. The QPSK BER is that BEFORE FEC is applied so the after FEC bit error rate is virtually nil.
Look for increases in the uncorrected errors in the output date , if you ever see them. A few bits per day perhaps out of hundreds of millions - what is your carrier downlink bit rate: 20 Mbit/s perhaps ? If your data throughput has dropped down it will be due to factors other than your dish pointing, which is clearly excellent. I would suspect congestion, configuration, routing problems etc, as you may now be on a different outlink carrier or have different hub configuration feeding out to the new type modem. Tell the hub all about your situation and ask for help. They can check your terminal, verify traffic routings and help with speed tests. Best regards, Eric. |
