1. An information transmission apparatus comprising:
a first line card;
a second line card;
a third line card; and
a bus connected to a first bidirectional buffer of the first line card, a second bidirectional buffer of the second line card, and a third bidirectional buffer of the third line card, the first bidirectional buffer, the second bidirectional buffer, and the third bidirectional buffer each configured to limit asymmetry in communication over the bus the third line card configured to send a first pulse per time interval signal over the bus to the first line card during a first time slot of a plurality of time slots that form a frame on the bus and to send a second pulse per time interval signal over the bus to the second line card during a second time slot of the plurality of time slots, the first pulse per time interval signal being a timing signal that is interleaved with control data, the first line card configured to send first information to the third line card over the bus during a third time slot of the plurality of time slots, the second line card configured to send second information to the third line card over the bus during a fourth time slot of the plurality of time slots, the third time slot assigned to a first location in the frame based on a first line card identification associated with the first line card and the fourth time slot assigned to a second location in the frame based on a second line card identification associated with the second line card.
