LTE-2X и NTE-2(B+)
Добавлено: 26 янв 2015 15:51
Есть PON дерево из LTE-2X и некоторого количества NTE-2
у одной из ONT наблюдаются стабильные потери пакетов:
заменили клиенту сам терминал, но проблему это не решило, все равно по трассировке уже от ONT до OLT есть потери. со стороны терминала уровень сигнала ~ -23dBm
явных причин проблемы не видим.
