Call 3
Description: The call to Andover is complete. The call to Princeton is still active when the
local bridge/router dials Palo Alto. Because the 28.8 Kbps path is not available, the
bridge/router uses the next available modem path, which is the 19.2 Kbps path. If there had
been a path faster than 19.2 Kbps, the bridge/router would have chosen the faster path.
