R/W
T1 Signaling channel. A value of 1 disables the use of the channel 24 and reserves it for
signaling. A value of 0 enables the use of the 24 channels to carry the cells. Valid only for
T1 mode.
TX Clock polarity: Rising edge of TXCK is used to output new data on DSTo if bit is 1.
Falling edge of TXCK is used to output new data on DSTo if bit is 0. Valid in Generic PCM
mode only
TX frame pulse polarity. Positive if bit is 1, negative if bit is 0. Valid in Generic PCM mode
only.

R/W
PCM Input port control. Data present at input port is sent to the Cell Delineation block
when the bit is 1. The data at the input port is ignored if the bit is 0.
Link Type: A value of 1 selects the E1 link type and 0 select T1 type.
PCM format: A value of 1 selects the ST-BUS mode and a 0 selects the Generic PCM
mode.
This is the PCM clock rate when the generic mode is selected. A 1 signifies a 2.048 Mhz
clock and a 0 signifies a 1.544 MHz clock. This is valid only for the T1 in Generic PCM
mode.
This bit defines the position of the PCM channels over the PCM in Stream. A value of 1
means that the 24 channels are grouped and are received in the first 24 channels on the
PCM stream. A value of 0 corresponds to 3 channels every 4 channels. Valid only for T1
type link, ST-BUS mode or Generic PCM mode with a bit rate of 2.048 Mbps.
T1 Signaling channel. A value of 1 disables the use of the channel 24 and reserves it for
signaling. A value of 0 enables the use of the 24 channels to carry the cells. Valid only for
T1 mode.
RX Clock polarity: Falling edge is used to sample data at DST if bit is 1. Rising edge of
RXCK is used to sample data at DSTi if bit is 0. Valid in Generic PCM mode only
RX frame pulse polarity. Positive if bit is 1. Negative if bit is 0. Valid in Generic PCM mode
only.
