This is Ms. Choi from Thailand. I'm working with Sub ISP in thailand and using TCH 1000 (used ㅜ.ㅜ) for internet service. TCH is quite good so far but I got a little problem about software version. Actually, I bought used TCH and no management contract with 3com so cannot get any update version of each ARC, DSP, NMC etc. Buying new TCH is still heavy for me. If you can give me those software version, it would be highly appreciated. ㅜ.ㅜ I've heard that these are the latest code (is it correct??) 3COM DSP 3.7.4 3COM Access Router Card 5.7.2 3COM Network Management Card 10.2.5 I'm looking forward to your reply soon. Thank you. ** Please help me !!! Best Regards Choi Thai System Integration Co.Ltd.
