介绍了DS2154这一第二代E1线路接口单元，它与前代产品在引脚和软件上兼容，具备前代功能并新增无晶体抖动衰减等特性。该产品符合E1规范，用户可通过并行端口快速访问内部寄存器，在处理器控制下为应用配置DS2154。

The DS2154 is a second-generation line interface unit for E1 lines. It is pin- and software-compatible with the first-generation DS2153Q and function- and pin-compatible with the DS2152, its T1 counterpart. The DS2154 retains all features of the DS2153Q adding crystalless jitter attenuation, additional hardware signaling, a full HDLC controller for the FDL layer with 16-byte buffers, and the option for nonmultiplexed bus operation.

The DS2154 meets E1 specifications, including ETS 300 011, 300 233, 300 166, TBR 12, and TBR 13 and ITU G.703, G.704, G.706, G.823, and I.431.

Through the parallel port, the user can quickly access the 8-bit internal registers and configure the DS2154 to the application under processor control.
