Function
Outgoing Connection Memory Page. The outgoing connection
memory page select signal, OCMP, controls the selection of the
connection memory page in the Outgoing Memory Switch Unit,
OMSU. When OCMP is set high, connection memory page 1 is
selected. When OCMP is set low, connection memory page 0 is
selected.
The byte location during which OCMP is sampled is dependant on
the mode of operation.
4-Frame SBI336 mode:
OCMP is sampled at the C1 byte position of the receive bus on the
first frame of the 4-frame multiframe (marked by RC1FP).
Changes to the connection memory page selection is synchronized
to the frame boundary of the next four frame multiframe.
48-Frame SBI336 mode:
OCMP is sampled at the C1 byte position of the receive bus on the
first frame of the 48-frame multiframe (marked by RC1FP).
Changes to the connection memory page selection is synchronized
to the frame boundary of the next 48-frame multiframe.
TelecomBus mode:
OCMP is sampled at the C1 byte position of every frame on the
receive bus (marked by RC1FP). Changes to the connection
memory pate selection are synchronized to the frame boundary of
the next frame.
OCMP is sampled on the rising edge of SYSCLK.
Receive Working Serial Data Select. The receive working serial
data select signal, RWSEL, selects between sourcing outgoing
data, ODATA[7:0], from the receive working serial data link,
RPWRK/RNWRK, or the receive protect serial data link,
RPPROT/RNPROT. When RWSEL is set high, the working serial
bus is selected. When RWSEL is set low, the protect serial bus is
selected. RWSEL is sampled at the C1 byte location as defined by
the receive serial interface frame pulse signal, RC1FP. Changes
to the selection of the working and protect serial streams are
synchronized to the SBI frame boundary of the next frame.
RWSEL is sampled on the rising edge of SYSCLK.
Input In-band Link User Signal. The input in-band link user
signal, IUSER2, provides external control over one of the bits in the
in-band link. The USER[2] bit in the header of the in-band
signaling channel of both the working and protection serial links will
reflect the state of this input.
IUSER2 an asynchronous signal and is internally synchronized to
SYSCLK.
Output In-Band Link User Signal. The output in-band link user
signal, OUSER2, reflects the state of the USER[2] bit in the header
of the in-band signaling channel of either the working or the
protection serial link, whichever is active.
OUSER2 is an asynchronous output.
Reset Enable Bar. The active low reset signal, RSTB, provides an
asynchronous SBSLITE reset. RSTB is a Schmitt triggered input
with an integral pull-up resistor.
