Section 3:

   When the Switching Capability field is PSC-1, PSC-2, PSC-3, or PSC-4,
   the Switching Capability specific information field includes Minimum
   LSP Bandwidth and Interface MTU.

   The Minimum LSP Bandwidth is encoded in a 4 octet field in the IEEE
   floating point format.  The units are bytes (not bits!) per second.
   The Interface MTU is encoded as a 2 octet integer.

I don't think this text is that clear. First of all, is the MTU value in octets or bits? I also assume that it is an unsigned integer, rather than a signed which the current language defaults to. 

The I wonder, is it clear on what level the MTU measurement is performed on. I know to little about what is actually represented by PSC-1 to PSC-4 to determine if the point in the stack the measurement is taken is always clear.
