说明

The DS2153Q is a first-generation line interface unit for E1 lines 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 is pin- and function-compatible with the DS2151Q, its T1 counterpart. It continues to provide an adaptable, single-chip interface unit at both central office and local E1 network interfaces.

The DS2153Q meets all E1 specifications, including ITU G.703, G.704, G.706, G.823, and I.431 as well as ETSI 300 011, 300 233, TBR 12, and TBR 13. Under processor control, the user can access the 71 8-bit internal registers to configure the DS2153Q to suit the application.
