10.9: Transmit Segmentation Throttle Counter
This register is loaded with the value in the Transmit Segmentation Throttle Register after each cell is
accepted for transmission and counts down until it reaches ’0’. A new cell transmission will not be requested
until this counter reaches ’0’.

10.10: MPEG Conversion Register
This register is used to convert MPEG time units into timeslot time units. If MPEG traffic is configured in the
LCD, the data stream will be monitored for PCRs. If a PCR is detected, it will be scheduled at the time speci-
fied in the PCR. A conversion factor needs to be written into this register to convert the MPEG time units into
timeslot units. It will be initialized to a value that converts the MPEG time units (90 KHz) into the timeslot units
(353.2 KHz, assuming one timeslot is the time it takes to send one cell over a SONET connection). The lower
12 bits of this register contain the fractional portion of this conversion factor.
