A managed, end-to-end wholesale IP transport service which does not require the wholesale end-user to install its own active electronics.
|
|
Broadband
|
A term applied to telecommunications systems capable of simultaneously supporting multiple information formats at relatively high speeds such as voice, high-speed date services and video services on demand. Overall transmission speeds are typically thousands of times faster than those of Narrowband systems.
