The here listed additional information should help you with a problem solution. However, an assurance for the correctness or wholeness of the statements doesn´t exist.
facility:
The feature of a Calls as well as within a Registration consists from the Facility-Length (1 byte) and the Facility-Field (0 ..63 bytes). By means of these statements, specific parameters can be arranged in term.

Protocol Identifier:
Broadly ale has User-data-field a length of 0 ..16 bytes the option and serves the transmission of beforehand information at the goal system.
If the bits are 7 and 6 of the first byte ZERO, the only 4 bytes serve as Protocol-Identifier for higher protocol layers, for example 01-00-00-00 for the PAD - followed from 12 bytes of User-Data as Logon-ID or Routing-Information for the PAD. (Numbers in HEX)
