Why the maximum number of links per link set in SS7 is limited to 16

The SLS field or Signaling Link Selection field is 4 bit length. Thus the range of the field is from 0 to 15 or 16. This imposes a restriction that at a maximum 16 links can be defined in a link set. If additional links are needed, then a new point code has to he created to support the additional links.
