-1) 
+1) '''Process Map''' : The BS decides the allocation of slots for the uplink and the downlink to the various SS. Each slot consists of the number
+of burst units allowed. For our TDM system we have assumed a equal slots for all the subscribers. Also, new Connection ID`s are allocated during
+this stage.
 
-2)
+2) '''Send Map''' : The Base Station broadcasts the map created in the above stage, using a special '''Connection ID''' 0, meant for all the 
+Subscriber nodes already in the system.
 
-3)
+3)'''DL Burst''' : The BS emits on the DownLink as specified by Map transmitted in the previous stage. To distinguish between each of the SS
+it uses a Connection ID, which corresponds to its own queues. This can be heard by all the nodes and they too distinguish it by their
+Connection ID.
+
+4) '''Contention Time''' : This stage is for future reserve. Any new SS wishing to join the system and already synchronized with BS would send in a Request 
+during this stage. For the time being we make the BS and the SS sleep during this period. 
+
+5) '''UL Burst''' : The BS receives on the UpLink as specified by Map transmitted in the previous stage. Again it distinguishes between various SS`s
+by the use of Connection ID.
+
+6) '''Map Sending''' : If the BS does not receive from any SS for a long time, it enters this special stage. After coming to this state, the BS
+emits MAPS Periodically and simply waits for the rest of the frame.
