• Reporting and controlling of slips
Writing of received data from XDI is controlled by SCLKX and SYPX/XMFS in
conjunction with the programmed offset values for the transmit time slot/clock slot
counters. Reading of stored data is controlled by the clock generated by DCO-X circuitry
and the transmit framer. With the dejittered clock data is read from the transmit elastic
buffer and are forwarded to the transmitter. Reporting and controlling of slips is
automatically done according to the receive direction. Positive/negative slips are
reported in interrupt status bits ISR5.XSP and ISR5.XSN.
A re-initialization of the transmit memory is done by re-programming the transmit time
slot counter XC1 and with the next SYPX pulse. After that, this memory has its optimal
start position.
The frequency of the working clock for the transmit system interface is programmable by
SIC1.SXSC and SIC1.SRSC to be 1.544 or 8.192 MHz.
Generally the data or marker on the system interface are clocked off or latched on the
falling edge of the SCLKX clock.
The following table gives an overview of the transmit buffer operating modes.
