CONNECTIONS 

2.01 

These  sets  are  factory-wired  for  use  with 

lAl,  1A2,  or  6A  KTS  line  circuits.  They 

may  also  be  used  with  lA  KTS  line  circuits  by 

modifying  the  set  as  shown  in  Table  A.  Line 

circuits  for lA, lAl,  or 1A2  KTS  may be  connected 
to  the  same  set  under  the  following  conditions: 

(a)  lAl  or  1A2  KTS  lines  must  be  connected 

to  the first key units with lA Jines connected 

to supplementary key  modules. 

(b)  lA,  lAl,  or  1A2  KTS  lines  should  not  be 

connected to  the  same 6  line  key module. 

(c)  lA,  1A1,  or  1A2  KTS  lines appearing behind 

a  m a n u a l   s w i t c h b o a r d   s h o u ld  n o t   be 

intermixed  at  a  CALL  DIRECTOR  telephone  set 

due  to  the  different  time  out  intervals  provided 
by  the  associated  KTU's. 

2.02 

These  636- and  637-type  (MD)  rotary  dial 

telephone  sets are  equipped  with 517A  jacks 

for  the  plugs  of  a  G3L  handset  or  a  head  telephone 
set.  The  internal  wiring  is  arranged  to  electrically 
connect  either  the  line  switch  or  the  headset  jacks 
to  the  line. 

2.03 

Replacement  or  substitution  of  the  key  in 

the  first  module  may  require  wiring  changes 

as  shown  in  the  notes  for  Fig.  3  and  4. 

Some  spade-tipped  conductors  or 
mounting  cord  leads  are  insulated 

with  tubing  which  should  be  cut  off 
with  electrician  scissors  or  diagonal 

pliers.  Other conductors 

are 

insulated 

with  stiff plastic pockets.  Pinch  open 
the  pocket  to  release  the  spade  tips. 

2.04 

When  station  busy  lamp  feature  is  required 

with  these  sets  having  1A1  or  1A2  KTS  line 

circuits, a P-90D033 Printed Wiring Board Assembly 

must  be  ordered  separately  and  installed  in  the 
636- or  637-type  telephone  set.  With  this  option, 
the  busy  lamp  will  light  whenever  a  line  pickup 
button  is  depressed  and  the  handset  is  off-hook  or 
the  headset  is  plugged  into  the  jack.  See  Fig.  6 

for connections and Section 502-600-100 for installation 

procedures. 

2.05 

Sets  equipped  with  a  D120C  mounting  cord 

manufactured  prior to  III-68  must use circuit 

per  Fig.  6  to  provide  station  busy  lamp  feature. 

2.06 

tThe  tip  and  ring  leads  of  lines  wired  for 

supplementary  hold  feature  must  be  run 

directly  between  the  key  telephone  equipment  and 

key  telephone  set.  The  A  and  lamp  leads  can  be 
routed  p e r   SD-6 9 530-0 1  a n d   D ivision  5 1 8
