Description of procedure

The basic LAPB procedures must be implemented to satisfy the following:

•standard use of the poll/final bit (for more information, see ISO-4375-1979-[E])

•exception condition reporting and recovery implemented in accordance with BX.25 and ADCCP specifications

•link set-up and disconnect implemented according to BX.25 specifications
