RATE[1:0]:
plane bit rate, the multiplexed bus will be enabled for the chip. When the RATE[1:0] select the 8.192 Mbit/s, the TSCKSLV (b5, E1-018H) must be set
to ‘1’.

Bit No.
Type
= 0: Transmit Clock Master mode is enabled.
= 1: Transmit Clock Slave mode or Transmit Multiplexed mode is enabled.
= 0: The data on the TSDn/MTSD and TSSIGn/MTSSIG pins is sampled on the falling edge of TSCCKB/MTSCCKB or LTCKn.
= 1: The data on the TSDn/MTSD and TSSIGn/MTSSIG pins is sampled on the rising edge of TSCCKB/MTSCCKB or LTCKn.
In Transmit Multiplexed mode, the DE of the eight framers should be set to the same value.
Valid in Transmit Clock Slave mode and Transmit Multiplexed mode.
= 0: The data on the TSCFS/MTSCFS pin is sampled on the falling edge of TSCCKB/MTSCCKB.
= 1: the data on the TSCFS/MTSCFS pin is sampled on the rising edge of TSCCKB/MTSCCKB.
In Transmit Multiplexed mode, the FE of the eight framers should be set to the same value.
= 0: The clock rate of TSCCKB/MTSCCKB is the same as that of the backplane.
= 1: The clock rate of TSCCKB/MTSCCKB is double that of the backplane.
The CMS of the eight framers should be set to the same value.
These bits determine the bit rate of the transmit data stream on the backplane. Note that if any of the eight framers selects the 8.192 Mbit/s back-
