Narrative:
At FL370; smoke was observed emanating from the forward center console. Followed SOP related to phase 1 event and initiating diversion to ETOPS alternate; notified ATC via cpdlc obtaining clearance; briefed and coordinated with cabin crew; briefed passengers; coordinated diversion with dispatch via HF phone patch. Smoke ceased and was clear within 2 minutes following circuit breaker E-12 automatically opening. Normal precautionary landing executed.of note related to operational challenges were:1) faulty cockpit/cabin interphone system causing difficulty in communicating with cabin crew at all stations. Cabin crew could hear and understand statements from the cockpit crew but the cabin crew statements were broken (suspect faulty jacks at flight attendant handsets).2) failure of voice communications to make or receive calls to/from dispatch.3) failure of ACARS printer related to receiving fully useable re-release and landing data. This information as presented on the mcdu is all but unusable.4) first flight attendant reported that initial PA made by captain was difficult to hear by passengers. She made a subsequent PA announcement generally repeating the information that had been provided. Suspect electrical short related to TCAS display unit located in forward center console.
