Methods and apparatus for enabling communication between network elements that operate at different bit rates

A method for enabling communication between a network element (NE) operating at a bit rate R1 and a NE operating at a bit rate R2, wherein a ratio of R2 to R1 is represented by a ratio M:N, where M and N are positive integers and M>N, the method comprising:

• receiving information, wherein the information is associated with distribution of electrical lanes of at least one of a number of M×K NEs operating at bit rate R1, wherein each electrical lane operates at a lane bit rate R0;
• determining a distribution of the electrical lanes of the at least one M×K NE based on the received information;
• interconnecting the electrical lanes of the at least one M×K NE with lane ports of at least one M:N electrical interface of N×K transceivers based on the determined distribution, wherein the at least one M:N electrical interface operates at a bit rate R2, and wherein each lane port of the at least one M:N electrical interface operates at a lane bit rate R0;
• and
• transmitting an indication identifying the distribution to the at least one M×K NE.
