This object specifies the actual largest service
frame size (in octets) that can be transmitted
through this SDP to the far-end ESR, without
requiring the packet to be fragmented. In order
to be able to bind this SDP to a given service,
the value of this object minus the control word
size (if applicable) must be equal to or
larger than the MTU of the service, as defined
by its svcMtu.
