The DS2151Q is a first-generation line interface unit for T1 lines that that pioneered single-chip integration of multiple functions, combining long- and short-haul and framing functionality with dual elastic stores and an 8-bit parallel control port. It continues to provide an adaptable interface unit at both network and central office interfaces.
The DS2151Q meets T1 specifications, including ANSI T1 403-199X, AT&T TR 6241 (12-90), and ITU G.703, G.704 G.706, G.823, and 1.431. Under processor control, the user can access the 64 8-bit internal registers to configure the DS2152 to suit the application.
