Boasting Reliability and Comprehensive Maintenance
The Standard for Leased Circuit Services
Whether for LANs or voice and image communications, Digital Leased Circuit Service can provide you with high speed, quality and reliability. HSD is your best choice as the standard for leased circuit services, boasting high quality digital transmission circuits and superior maintenance and monitoring systems.
HSD can give you an optimal communications environment as your company's communications backbone.
If your company transmits large amounts of information, the high-grade digital leased circuit service HSD is an excellent choice as your trunk line. You can choose from 12 different transmission speeds from 64kbit/s to 6Mbit/s to create a network matching your needs.
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.
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.
Lines are backed up with branch lines to improve reliability in terminal sections.
If damage occurs in the terminal section, trans-mission is automatically switched to the branch (spare) line.
Make your network simpler and more economical by combining circuits for different uses, such as phone and data transmissions.
