Functional Description
2.1
Switching Configuration
The device supports five switching configurations. (1) Backplane-to-Local, (2) Local-to-Backplane, (3) Backplane-
to-Backplane, (4) Local-to-Local, and (5) Uni-directional switch. The following sections describe the switching paths
in detail. Configurations (1) - (4) enable a non-blocking switch with 8192 input channels and 8192 output channels
at Backplane stream data-rates of 16.384Mb/s or 32.768 Mb/s, and Local stream data-rates of 16.384Mb/s. The
switch paths of Configurations (1) to (4) may be operated simultaneously.
2.1.1
Backplane-to-Local path
The device can provide data switching between the Backplane input port and the Local output port. The Local
Connection Memory determines the switching configurations.
2.1.2
Local-to-Backplane path
The device can provide data switching between the Local input port and the Backplane output port. The Backplane
Connection Memory determines the switching configurations.
2.1.3
Backplane-to-Backplane path
The device can provide data switching between the Backplane input and output ports. The Backplane Connection
Memory determines the switching configurations.
2.1.4
Local-to-Local path
The device can provide data switching between the Local input and output ports. The Local Connection Memory
determines the switching configurations.
2.1.5
Uni-directional Switch
The device may be optionally configured to provide a 16,384 x 16,384 uni-directional switch by grouping together
all input and all output streams. All streams may be operated at a data-rate of 16.384Mb/s, or a combination of
16.384Mb/s and 32.768 Mb/s. Lower data-rates may be employed with a corresponding reduction in switch
capacity.
2.2
Port Data Rate Modes and Selection
The selection of individual stream data-rates is summarized in Table 1.
2.2.1
Local Port Rate Selection
The local port has 32 input (LSTi0-31) and 32 output (LSTo0-31) data streams. All input and output streams may
be individually selected for operation at a data rate of either 2.048Mb/s, 4.096Mb/s, 8.192Mb/s or 16.384Mb/s. The
timing of the input and output clocks and frame pulses are shown in Figure 6, Local Port Timing Diagram for 2,4,8
and 16Mb/s stream rates.
2.2.1.1
Local Input Port
The bit rate for each input stream is selected by writing to a dedicated Local Input Bit Rate Register (LIBRR0-31).
Refer to Table 41, Local Input Bit Rate Register (LIBRRn) Bits.
