The V5 Envelope Function Sublayer exchanges information between the AN and the LE. The format of the frame is as follows:


Function Octet
Flag: 0 1 1 1 1 1 1 0 1
Envelope function address 2
none 3
Information 4 ... n
FCS n-2, n-1
Flag: 01111110 n


The envelope function address field consists of two octets. The format of the envelope function address field is shown here:
3 - 8 2 1
EFaddr 0 EA 0
EFaddr (cont.) EA 1

The envelope function address is a 13 bit number.


The envelope information field of a frame follows the envelope address field and precedes the frame check sequence field. The contents of the envelope information field shall consist of an integral number of octets. The default value for the maximum number of octets in the envelope information field is 533 octets. The minimum envelope information field size is 3 octets
