Dissector handles operation 61 wrongly.
It expects field (OPID) between LNPI and RES1 but according to UCP
specification 4.6 there is no field in between.
Dissector code snippet:
...
UcpHandleByte(hf_ucp_parm_LNPI);
UcpHandleInt(hf_ucp_parm_OPID); /* <-- Wrong in my opinion. */
UcpHandleData(hf_ucp_parm_RES1);
if (OT == 61) {
UcpHandleData(hf_ucp_parm_RES2);
}
