Whats's this cable?

What is this NBN wire? cable & conduit has recently been unearthed as rain has washed away the surrounding dirt. It seems someone has kicked/stomped it. I think its a Telstra pit, cover is unbranded. Another pit labelled Telstra is on the opposite side of the pavement. Theres a funky 3-way join too. Maybe the old original phone cable to the house that was here before it was knocked down and replaced by units? (circa 2000) Phone lines and FTTC boxes serving this apartment building are in another pit about 10m further down
