i learn, from my book,
that 3C2W coaxial cables can support 45MB leased line up to 90meters of length
but i learn, from other's experience,
that 3C2W coaxial cables, will start giving errors after 80meters of length
i learn, from the internet and books,
that when router shows serial is up, line protocol is down
the physical line is definitely down.
but i learn, from my own experience,
that sometimes, it can be router's fault, reset it.

i learn, from the courses and training sessions,
test gears test result is almost accurate,
if it shows no error, there's no error then, confirm.
if it shows no error, there's no error then, confirm.
but i learn, from my mistakes,
that test gears are also a tool,
it may and may not detect whatever it suppose to detect.
I guess i've learn,
that books, courses, trainings are good references.
But experience and mistakes,
is the best reference.
The best teacher.
To myself, good luck!

hang jangan tak tau, aku ada suruh customer aku tarik 130m 3C2W internal wiring. seb baik circuit up. sebab memang tadak choice. dia nak diversity, so aku kena pakai node jauh sket. so far, tadak complaint lagi. node TEllab lah tapi. so aku rasa mebe signal level from tellab higher than marconi.
