  4. Issues (continued) • Should the use of new the TLVs in Error_Spec be allowed? • Four new TLVs • Reference_count • Severity • Timestamp • Error_string • Code points for well known and standard Alarms • To be carried in Error Values using new Error Codes • Identified ITU and Telecordia specs use strings not values • Options: • Define string to value mappings for some/every spec • Punt, i.e., stay with using strings CCAMP - 58th IETF
