Asymmetrical Frames
When Using the Protected Paths feature with the Asymmetrical frames,
you will be able to protect half the outputs but those protected outputs
cannot be greater than half the number of inputs. For example, the 128x256
router:
• Outputs 0 – 127 (1-128) could protect outputs 128 - 255 (129-256) but
only 64 of these outputs.
That means:
• Outputs 0 – 63 (1-64) could protect outputs 128 – 191 (129 – 192)
• or Outputs 64 – 127 (65 – 128) could protect outputs 192 – 255 (193 –
256).
