 On  January  31,  2001,  applications  filed  by  TMI  Communications  and  Company,  Limited  Partnership  were  placed  on  Public  Notice. 
 (See  File  Nos.  SES-  ASG-  20010116-  00099;  SES-  MOD-  20010116-  00097;  SES-  MOD-  20010116-  00098;  Report  No.  SES-  00357  (January 
 31,  2001)).  Pursuant  to  Section  25.154  of  the  Commission's  rules,  the  deadline  for  filing  pleadings  concerning  TMI's  application  was 
 March  2,  2001.  On  March  2,  2001,  we  suspended  the  deadline  for  filing  pleadings  concerning  TMI's  applications  so  that  a  common 
 deadline  for  all  pleadings  concerning  the  above-  referenced  applications  could  be  established.  (See  Comment  Deadline  Suspended 
 Concerning  TMI  Communications  and  Company,  Limited  Partnership,  Report  No.  SPB-  163,  March  2,  2001).  By  this  public  notice,  we 
 are  extending  the  comment  dates  for  the  TMI  applications  to  coincide  with  the  pleading  cycle  established  in  this  Public  Notice.

 Motient  concurrently  filed  an  amendment  (File  No.  SAT-  AMD-  20010302-  00019)  to  its  application  for  a  next-  generation  system. 
 (File  Nos.  SAT-  LOA-  19980702-  00066;  SAT-  AMD-  20001214-  00171)  The  amendment  includes  a  request  to  deploy  terrestrial  base 
 stations  in  the  1626.5-  1660.5/  1525-  1559  MHz  bands,  to  be  used  with  user  terminals  in  high-  traffic  areas  and  where  the  satellite  signal 
 is  blocked.  Motient  seeks  a  waiver  of  any  Commission  rules  that  prevent  use  of  these  bands  for  this  purpose.  We  are  not  accepting  the 
 amendment  for  filing  insofar  as  it  seeks  authority  for  terrestrial  base  stations,  but  are  instead  seeking  comment  on  Motient's  request. 
 Thus,  with  respect  to  the  terrestrial  base  station  portion  of  Motient's  application,  petitioners  to  deny  need  not  file  by  the  deadlines 
 established  by  this  public  notice.  With  this  exception,  we  are  accepting  for  filing  Motient's  request  for  a  second  generation  satellite 
 system  to  provide  replacement  capacity  for  its  currently  authorized  satellites. 


 Ccomments  and/  or  petitions  to  deny,  as  appropriate  for  the  issues  described  above,  must  be  filed  on  or  before  April  18,  2001.  Replies 
 or  oppositions  may  be  filed  on  or  before  April  30,  2001.  Responses  may  be  filed  on  or  before  May  7,  2001.  All  pleadings  filed  in  this 
 proceeding  should  reference,  at  a  minimum,  the  lead  File  Number  SAT-  ASG-  20010302-  00017. 


 We  will  coordinate  action  on  Motient's  application  for  a  second  generation  system  with  the  National  Telecommunications  and 
 Information  Administration  since  the  proposed  system  would  operate  in  spectrum  shared  with  the  Federal  Government. 


 For  further  information  concerning  the  assignment  and  transfer  of  control  applications,  and  second  generation  system  applications, 
 contact  Terrence  E.  Reideler  at  202-  418-  2165.  For  information  concerning  the  Motient's  proposed  terrestrial  base  stations,  contact 
 Mr.  Reideler  in  the  International  Bureau,  or  Herbert  Zeiler  (WTB)  at  202-  418-  0686.
