I designed & implement swap of NSN old ADM (hiT 7060) by Huawei ADM OSN7500, OSN3500 & OSN2500 in our optical backbone sites (about 40 sites) during 2007/08. It was great time for me. Flexibility option of Huwaei ADM helped me to design & implement properly & also enable me to complete my project in due time. This project was highly appreciated by my management.

Thanks a lot Huawei Team... 

we were very happy with Huawei ADM performance in our network...
