TN464C Jumper Settings
If the TN464C or later is used , two jump ers on the b oard  must b e installed  
c orrec tly. These jump ers are on the lower left quad rant of the b oard  as you look 
at the b oard  with the front p anel in your rig ht hand . One jump er c ontrols the b it 
rate and  the other c ontrols the imp edanc e. The 75-Ohm op tion is for use with 
c oaxial c ab le. The following  fig ure illustrates these jump ers:

DS1/CEPT1 Board Cable to CSU
A stand ard  c ab le is p rovid ed  with the DS1/CEPT1 b oard  for c onnec ting  to a CSU 
or other network terminating  eq uip ment, suc h as a T1 multip lexer or a T1 
mic rowave. This c ab le is 50 feet in leng th and c omes eq uip ped  with a 25-p in 
c onnec tor at the G3V2 end  and  a 15-p in c onnec tor at the CSU end . Extend er 
c ab les c an also b e ord ered  if the CSU is more than 50 feet from the DS1/CEPT1 
board.
75 Ohm DS1/CEPT1-to CSU Cable
If the TN464 (C or later) b oard  is used  and  is op tioned for 75 Ohms, a c oaxial 
c ab le with a 75 Ohm c onnec tor is req uired . Presently, the d istrib utor makes this 
c ab le using  c oaxial c ab le and  a c oax-to-25 p in ad ap tor c onforming  to the CCITT 
G703 stand ard  for 75 Ohm interfac e.
ESF T1 Channel Service Unit
A c hannel servic e unit is req uired  if the ap p lic ation req uires c onnec tion to the 
p ublic  network with c opp er wire. AT&T p resently sells the ESF T1 CSU for these 
ap plic ations. The DS1 c ab le from the DS1 b oard  on the switc h c onnec ts to the 
CSU at one end . The CSU then c onnec ts to the network interfac e, whic h is 
usually a smart jac k, at the other end. Thus, the CSU is an interface between the 
c ustomer p remises eq uip ment and the network T1 fac ility. The p rimary p urp ose 
of the CSU is as follows:
nThe CSU ac ts as a line rep eater so that the network interfac e c an b e 
loc ated  at varying distanc es from the nearest rep eater in the network and  
still maintain the correct sig nal level.
nThe CSU p rovid es loop b ac k test c ap ab ilities b oth from the c ustomer sid e 
and  from the network sid e.
nThe CSU isolates the c ustomer premises eq uipment from the network, 
providing network equipment protection against electric al damage from 
the c ustomer eq uip ment. This func tion is not req uired  anymore b ec ause of 
c hanges in the network equip ment.
nThe CSU p rovid es automatic  1s d ensity req uirement to the network in the 
event that the c ustomer premises eq uip ment is d isc onnec ted .
User op tionab le switc h setting s on the CSU p rovide these func tions.

ESF T1 CSU Switch Settings
The ESF T1 CSU should  b e optioned  to ag ree with the switc h administration. 
Thus, if the system is op tioned  for ESF framing  format, for examp le, so should  the 
CSU. The ESF T1 CSU should  also b e set to pass ESF and  CRC-6 information 
transparently throug h the CSU to and  from the system.
ESF T1 CSU DIP Switch Settings
Following  are the typ ic al DIP switc h setting s for the ESF CSU when c onnec ted  to 
a T1 fac ility. Note that these setting s are assuming  ESF framing  and zero c od e 
sup p ression (ZCS) line c od ing  format in the switc h.

SW4 SW2 This switc h is unused . All eig ht switc hes are fac tory set 
to op en.
SW5-1 SW1-8 op en This setting  ind ic ates that the switc h is ESF framed . ESF 
framing  must also b e set in the DS1 c irc uit p ac k 
ad ministration form. If the switc h is c losed , D4 framing  is 
selected.
SW5-2 SW1-7 c losed This setting  ind ic ates that the network line c od ing  format 
is AMI (ZCS in DEFINITY terminolog y). At p resent, the 
network d oes not sup p ort B8ZS end -to-end. Thus, AMI 
(ZCS) is usually the c orrec t op tion for c onnec tions to the 
p ub lic  network. Note that if you are using  unrestric ted  
fac ilities, you must use B8ZS. The op en p osition selec ts 
B8ZS.
SW5-3 SW1-6 c losed This setting  ind ic ates that the switc h is ad ministered  for 
ZCS line c oding  format (AMI in network terminolog y). 
Sinc e the network d oes not in g eneral sup p ort B8ZS 
end -to-end , ZCS should  normally be ad ministered  in the 
DS1 c irc uit p ac k ad ministration form for c onnec tions to 
the p ub lic  network. This switc h setting  must ag ree with 
the SW5-2 setting . For examp le, if one is AMI (ZCS) then 
the other must also be AMI (ZCS), and  similarly for 
B8ZS. The op en p osition selec ts B8ZS.
SW5-4 SW1-5 c losed This setting  allows the CRC-6 error c orrec tion c od e from 
the network to b e p assed throug h unaltered  to the 
switc h. If the switc h is optioned  for ESF, this is the 
c orrec t setting . If the switc h is op tioned for D4, this 
switc h is ig nored . The op en p osition terminates the 
CRC-6 from the network.

AMI (ZCS) line c od ing  from the switc h. If set to c losed , 
the CSU d ec od es B8ZS. The switc h should  normally b e

op tion must b e set the same as for the switc h, for 
examp le, if one is set to AMI (ZCS), so must the other.
SW6-3 SW7-3 op en This is the d efault setting . This setting  is for d ec od ing  
AMI (ZCS) from the network sid e. It should  b e set the
