+
+=== channel assignment FSM
+
+* have a FSM for a channel assignment
+** started by BSSAP ASSGN REQ from MSC
+** RF channel allocation
+** RSL channel activation 
+** MGCP for A side (AoIP)
+** MGCP for Abis side to bsc-mgcp
+** IPA RSL xxCX (Abis/IP)
+** queueing?
+
+* should this simply be a 'lchan fsm'?
+* should lchan be separate sub-fsm?
+* each MGCP operation sub-fsm?
+
+=== MGCP CallAgent Endpoint FSM
+
+* Transmit + Retransmit CRCX, MDCX, DLCX
+* Receive ACK/NACKs
+* user API to create/modify/delete
+
+=== IPA xxCX CallAgent Endpoint FSM
+
+* Transmit + Retransmit CRCX, MDCX, DLCX
+* Receive ACK/NACKs
+* user API to create/modify/delete
+** share that API/SAP with MGCP CA
+
+=== lchan FSM
+
+* Transmit RSL CHAN ACT 
+* Receive RSL CHAN ACT ACK/NACK
+* SAPI handling?

+== MGW Design Notes
+
+=== Functionality
+
+* use libosmo-abis to open traffic E1/T1 slots
+* subch_demux for 16k sub-slots
+* TRAU frame parsing/generation for all codecs
+* fully controlled by MGCP
+* different endpoint classes
+** endpoints to PCM ports
+** endpoints attached to 'RTP packet bridge'
+** osMUX endpoints
+* transcoding between codecs
+* de-jitter
