TUP: Message format

The standard routing label has a length of 40 bits and is placed at the beginning of the Signalling Information Field of a MSU:

Octets 1-4: Routing Label
bits 14-1 DPC: Destination Point Code
bits 28-15 OPC: Origine Point Code
bits 40-29 CIC: Circuit Identification Code
Octet 6: Heading
bits 4-1 Heading code H0
bits 8-5 Heading code H1
