Speed of
(Mbps)
The guaranteed total bit rate of the channel (622.080 Mbps) is lower than the aggregate port rate (780 MHz). This is an
example of a TSBUS application where stuffing would guarantee the bit rate to be within the maximum tolerated by the
CX28560.

Configuration
The CX28560’s configuration options are extremely flexible. Each logical channel
can be assigned to a physical stream ranging from a DS-0 (64 Kbps) to 52 Mbps. The
CX28560’s serial ports can interface to a standard PCM highway or TSBUS.
Examples of configurations are listed in
The send and receive data can be formatted in the HDLC messages or left
unformatted (transparent mode) over any combination of bits within a selected time
slot. The CX28560’s protocol message type is specified on a per-channel basis.
