1 / 4 page  Fully-Featured T1/E1/J1 Framers The highly integrated T1/E1/J1 framers from Mindspeed Technologies™ drive down per-port framer costs, support a scalable system roadmap, and provide a single 3.3 V chip for T1, E1 and J1 applications. They support current ANSI, ETSI, ITU-T, TTC-JT and Bellcore standards. Physical-layer support is provided for alarm generation and detection, error monitoring, per-channel trunk conditioning, and Facility Data Link (FDL) maintenance. Data link layer support is provided for signaling channels (LAPD/SS7) as well as robbed bit (T1) and time slot 16 (E1) Channel Associated Signaling buffers. A serial Time Division Multiplex (TDM) system bus interface allows the backplane Pulse Code Modulation (PCM) data highway to operate at rates from 1.536 to 8.192 Mbps, with separate TDM buses or combinations of up to four ports multiplexed onto a single TDM bus. Provision of both transmit and receive slip buffers means that the system interface may be connected to a common backplane for both T1 and E1 services. An additional benefit of this flexibility is that a gapped system interface may be used, at clock rates up to 8.192 MHz. The parallel eight-bit microprocessor port supports Intel- or Motorola-style interfaces. Control and status registers may be memory-mapped and all interrupts from real-time events may be separately masked and latched. An embedded serial port is included in the CN8394 and CN8398 as an extension of the parallel microprocessor interface and may be used to control external line interface units (LIUs) and other peripheral devices. The framers may be connected directly to most LIUs for non-multiplexed T1 or E1 connections, or to an external mux for higher-rate connections, such as DS3 and E3. Both unipolar (single-rail) non-return to zero (NRZ) and bipolar encoded line interface formats are supported.
