Bypassing Configurations
Dual-link configurations also enable direct transfer of channel between the two
links (this is called
bypassing
). This function requires the presence of a KDI module
in MX-2100.
shows the operation of the basic bypassing configuration. In
some of the users at location A are connected to users at location B,
and other users at location A are connected, using the bypassing function of the
KDI module, to users at location C (the connection is full duplex). As explained
above, with respect to bypassing, the multidrop channel is handled either as a
bypassed channel, or as a dropped channel, depending on the state of the RTS
line.
The KDI module supports the bypassing of one contiguous block of bits from one
link to the other. The bypassed block is specified by three parameters:
•
The position of the first bit (the starting bit) of the block to be bypassed in the
multiplexed frame of main link A
•
The number of bits to be bypassed (the block size)
•
The position of the first bit (the starting bit) of the block in the frame of main
link B. This may differ from the starting bit on main link A.
