Full availability, nonblocking 2048-channel time/ space switch. 2.048 Mbits/s (32 time slots), 4.096 Mbits/s (64 time slots), or 8.192 Mbits/s (128 time slots) data rates, independently programmable per highway. 64 kbits/s granularity with optional 32 kbits/s (4-bit) and 16 kbits/s (2-bit) subrate switching, selectable per highway. Low-latency mode for voice channels. Frame integrity for wideband data applications. Concentration highway interface (CHI) compatible with the IOM2, GCI, K2, SLD, MVIP *, ST-Bus, SC-Bus, and H.100. Single highway clock and frame synchronization input. Independently programmable bit and byte offsets with 1/4 bit resolution for all highways. Capable of broadcasting data to the transmit highways from a variety of sources including host data. High-impedance control per time slot. Software-compatible family of 1K, 2K, and 4K timeslot interchangers. Thirty-two independent high-impedance indicators (output enables) for transmit highways, allowing external drivers. Direct access to device registers, connection store, and data store via microprocessor interface. IEEE † 1149.1 boundary scan (JTAG).
