This product is a T1 Single-Chip Transceiver, which can be used for DS-1 long haul or DSX-1 short haul lines. It has complete DS1/ISDN-PRI transceiver functionality, and the line interface can handle long-haul and short-haul trunks.
The DS2151Q T1 Single-Chip Transceiver (SCT) contains all necessary functions for connecting to T1 lines, whether they be DS-1 long haul or DSX-1 short haul. The device includes a clock recovery circuitry that automatically adjusts to T1 lines from 0 feet to over 6000 feet in length and can generate both DSX-1 line build outs as well as CSU build outs of -7.5 dB, -15 dB, and -22.5 dB.
The onboard jitter attenuator is selectable to either 32 bits or 128 bits and can be placed in either the transmit or receive data paths. The framer locates frame and multiframe boundaries and monitors the data stream for alarms. It also extracts and inserts Robbed-Bit signaling data and FDL data. The device contains a set of 64 8-bit internal registers accessible via an 8-bit parallel control port.
