Packet Mode Questions
#1
The section of the specification documentation on packet-mode say puncturing uses a 7/8 matrix (1, 1, 1, 1, 1, 1, 1, 0) but the Physical Layer section discusses 2 different puncturing matrices that are much longer. (P1 for the LSF and P2 for all other frames) Which is actually used for packet-mode frames? I assume a packet-mode LSF uses P1 as described.

The specs also say a packet-mode super-frame has 798 bytes of payload, but I can't figure out how regular frames fit into this evenly or if subsequent frames include LICH chunks like with stream-mode.

Finally, I gather that LICH refers to the data in the LSF, but what does LICH actually stand for?
