MPM-1000A Operator Manual

a.  AROW: The assigned ROW slot is used by the NM to communicate back to the 

NC and request network resources. After login, each NM is assigned a time and 
frequency in which it must provide its AROW to the NC. This allocates an AROW 
slot in each frame and the NM is required to send this AROW each frame. If the 
NM fails to provide its AROW for a given number of consecutive frames, the NC 
will log the NM out of the network since it appears not to be responding.  

b.  CROW: The contention ROW slot is used by the NM to communicate to the NC 

to  request initial  log  in  to  the  network.  It  is  labeled  a  “contention”  row  because 
there could be two (2) or more Terminals trying to use the CROW frequency and 
time slot within the frame in order to request a log in. If this contention happens, 
there  are  mechanisms  in  NCW  that  will inform  those  two  (2)  or  more  Terminals 
on how to prioritize use of the CROW. The amount of CROW slots available for 
member  login  is  operator  settable  and  is  usually  dependent  on  the  anticipated 
size  of  the  network.  Any  non-registered  node  can  contend  for  an  available 
CROW slot. The spread factor for the CROW is selectable at the NC only. 

8.2.3  Data Communications Burst (DCOM) 

The  DCOM  slot  or  burst  is  similar  to  an  Orderwire.  The  DCOM  is  assigned  a  specific 
frequency and time within a frame in order to communicate data within the network. The 
DCOM  is  reserved  for  data  (IP)  traffic. The NC  schedules and assigns  DCOM  slots  to 
NMs  based  on  priority  queue  buffer  reports  contained  within  the  AROW.  This  data 
communications  could  be  between  NC  to  NM,  or  NM  to  NM,  or  NM  to  the  NC.  (See 
Figure 8-1)  
 
DCOM  traffic  Quality  of  Service  (QoS)  is  defined  with  a  DiffServ  code  point  (locally 
defined). Code points can be assigned a SATCOM priority level of 0-15 for transmission 
by the Modem. 

8.2.4  NCW Traffic Example  

Figure  8-2  MF-TDMA  Structure,  shows  an  example  of  how  MF-TDMA  frames  may 
contain the various types of Orderwires and DCOM bursts.
