This attribute gives the total number of path setup requests that
resulted in an LCh/n or Vcc/x.y clash. A large value for this number
is an indicator of poor performance by the PathAdmin in its
allocation of LCh/n or Vcc/x.y components. In general the channels
will be allocated in opposite orders at each end of the Trunk but this
may not always be the case. Note that as the PathAdmin runs out of
LCh/n or Vcc/x.y components the number of clashes will increase.
