Abstract
A process for testing a wrapped segment of a dual token ring transmits idle signals on the segment and monitors the received signals. If either an Active Monitor, Standby Monitor or Beacon frame is received the process loops. If a Ring Purge frame is received the process exits successfully and the segment is unwrapped. If a timer expires prior to the above, transmission shifts to a Claim Token frame. The process loops if a Beacon frame is received or if one of two timers expires. The process exits and the segment is unwrapped if a Ring purge frame is received or if n Claim Token frames are received having the hub source address.
