Although the definition for narrowband has become somewhat fuzzy, traditionally bandwidth at 1.544 Mbps or less has been the norm. Since most carriers move information over large infrastructure pipes, getting to narrow bandwidths may take a series of multiplexing equipment.
ADTRAN's Narrowband Access products provide the functionality to break down high level bandwidth signals into DS1, FT1, and DS0. Our product platforms combine the features sought by carriers to ease muxing requirements yet deliver the services demanded by customers. Providing multiple functions from one platform enhances network synergy and helps control capital expenses.
