Communication Link Initiation Method and Apparatus

A method implemented by a second node, wherein the method comprises:

• receiving, from a first node, a ninth information frame comprising fifth synchronization information and a fifth training information frame,
• wherein the fifth training information frame is a forward training information frame or a reverse training information frame,
• wherein the reverse training information frame comprises one or more of a reverse training information frame type, a first pre-emphasis gear, or a first swing gear, and
• wherein the forward training information frame comprises one or more of a first count of remaining forward training information frames, a forward training information frame type, or a second swing gear.

An apparatus comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to cause the apparatus to:
• receive, from a first node, a ninth information frame comprising fifth synchronization information and a fifth training information frame,
• wherein the fifth training information frame is a forward training information frame or a reverse training information frame,
• wherein the reverse training information frame comprises one or more of a reverse training information frame type, a first pre-emphasis gear, or a first swing gear, and
• wherein the forward training information frame comprises one or more of a first count of remaining forward training information frames, a forward training information frame type, or a second swing gear.
