A Trustworthy Maintenance and Administration System

A Trustworthy Maintenance and Administration System

Every circuit of the HSD is monitored, so if damage occurs in the terminal sections between NTT EAST and the customer, we can provide prompt restoration service.

Optional Service

Multi-Line Access Service

Several digital leased circuits (HSD) in a single facility are handled by one circuit connection device (DSU). This makes multiple access possible with only one user or net interface, so Multi-Line Access Service subscribers do not need to pay any installation costs other than for the first line. Also, fewer DSU devices are necessary, which keeps down your DSU usage costs and saves space.

  • *The amount of money without a mention of "Including tax" is a price of tax excluded.
  • *The total amount calculated based on the price of tax excluded would be the amount claimed.
  • *The actual amount claimed has the case that it differs from the amount of money at the time of being calculated based on a price including tax.
