Document describing frames used in
TDMA NOKIA 5120 / 5160 / 6120 / 6160

TDMA phones support simultaneously both MBUS protocols
(see nokia.txt for protocol details)
the old one (version1) and the new (version2). Both protocols can be used
at the same time on the MBUS. The phone will decode both and react accordingly.

Correct format is MBUS version 1:

 List:

0x17:
    s Release key           {+0x00, keynum }
    s Press key             {+0x01, keynum }
0xe9:
    s Start connection      {+0x01 0x01 0x1c 0x01 0x1c}
      (3Com cell modem card)Note: this is message with SrcDEV = 0xf8 !
                            ACK frame for it is (DestDEV = 0xf8 too) 0x1c, 0x01, 0x1c
    s Start connection      {+0x00 0x02 0x1d 0x00 0x1d}
                            Note: this is message with SrcDEV = 0xf8 !

Other frames from 3Com cell modem card (MBUS version 1):
   unknown purpose : 00 E0 00 1D SQ CS
       probably request 
       Alive response from cellmodem 
   UC_RESERVE_REQ:   00 E0 05 19 00 00 01 01 00 SQ CS
       register system state info presentation 
   UC_RESERVE_REQ:   E0 00 01 CD 01 SQ CS
       phone tries to register some info from cellmodem 

   Dialing as cellmodem forces the phone into analoge AMPS mode,
   answering a call as cellmodem answers in AMPS mode 
   This allows transparent transmission of the analoge modem tones since
   digital TDMA won't transmit them transparently. 
   It also switches audio to the XEAR , XMIC pins automatically. 

   LN_ALIVE_REQ:     E0 00 00 1E SQ CS
       checks if cellmodem is still present (sent 1 /sec.) 
   SYS_STATE_IND:    FF 02 07 CA 1C Con 02 01 0E 0F 00 SQ CS
       sytems state information 
       Con holds the connection state 
         00 = idle 
         01 = ringing 
         02 = connecting 
         03 = talk 
         04 = ringing / alternating with 01
       the destignation is the Global object and the source
       is subaddress 02 of the Nokia phone. 

Correct format is MBUS version 2:

                                             0x04: reset (PIN is requested)
                                                   In 5110 makes reset without PIN
