TIMING CHARACTERISTICS
Detailed timing diagrams for the MRT are illustrated in Figures 3 through 9. All output times are measured with
maximum load capacitance appropriate for the pin type. Timing parameters are measured at (V

Line Side Timing Characteristics
The line side timing characteristics of the MRT are designed so that the line output mask at the transformer
output meets the wave shapes specified in CCITT recommendation G.703 for 34 and 8 Mbit/s operation and
the NTT Technical Reference for High Speed Digital Leased Circuit Service for 6 Mbit/s operation. The pulse
masks for each of the three modes of operation are shown in Figures 3, 4, and 5. Refer to the corresponding
standard cited in each case for further details regarding the interface.
