Just see if I can get an idea of what Erik is aiming at:
ISO SEQUENCE FOR DIALLING A TELEPHONE LINE                   HAYES EQUIVALENT
                                                            

N-Connect(CldNsap=NSAP indicating telephone number 1234567)
   <processing inside network layer>
   <skip the data-link layer>
   Ph-Activate(connection to modem)                      -> ATDT
   Ph-Send(1234567)                                      -> 1234567\n
   Ph-Deactivate(connection to modem)                    <- CONNECT 2400\n
   Ph-Activate(connection THROUGH modem)                    (was done by modem)
   Ph-Data(Link layer construct with N-Connect)             Send data
N-Disconnect
   Ph-Deactivate(connection THROUGH modem)                  +++
   Ph-Activate(connection to modem)                         OK\n (from modem)

Surprise! It nearly fits!
If the standard okays both ends of a line doing things to it, that is....
