The following instruc tions are typ ic al for most installations. But follow the 
instructions supplied with the printer.
1. Unp ac k and  set up  the p rinter ac c ord ing  to the instruc tions sup p lied  with 
the p rinter.
2. Be sure that the p rinter has p ap er, the rib b on is p rop erly installed , and  the 
cover is closed.
3. Connec t one end  of the printer c ab le to either the serial or p arallel p ort on 
the PC (d ep end ing  on the PC and p rinter). Sec ure the c onnec tor with the

DS1/T1 CPE Loopback Jack
This c hap ter provid es information on how to install and  use a DS1 loop b ac k jac k 
to test the DS1 sp an b etween the DEFINITY and  the network interfac e p oint. The 
loop b ac k jac k is req uired  when DC p ower is at the interfac e to the ICSU. 
NOTE:
Do not remove the loop b ac k jac k after installation. It should  always b e 
availab le for remote tests of the DS1 sp an.
The loop b ac k jac k isolates the ICSU from the DC power and  p rop erly loops the 
DC sp an power.
NOTE:
The loop b ac k jac k op erates with DS1 c irc uit p ac ks and  R7 or later 
software. The loop b ac k jac k op erates with the 120 integ rated  c hannel 
servic e unit (ICSU) only. It d oes not sup p ort 3100-series c hannel servic e 
units or other external CSUs or older ICSUs.
Installing Loopback Jacks 
You c an install a loop b ac k jac k with or without a smart jac k.
With a Smart Jack
Install the loopb ac k jac k at the interfac e to the smart jac k, if p ossib le. This 
p osition p rovid es maximum c overag e of CPE wiring  when remote loop b ac k tests 
are run. 
If the smart jac k is not ac c essib le, install the loop b ac k jac k at the extend ed  
demarcation point.

If there is no extend ed  demarc ation p oint, install the loop b ac k jac k direc tly at the 
network interfac e p oint as shown in Fi g u re  3 4
.
If there is an extended  d emarc ation p oint and  the smart jac k is not ac c essib le, 
install the loop b ac k jac k as shown in Fi g u re  3 5
.
If there is an extend ed  d emarc ation p oint, b ut the smart jac k is ac c essib le, install 
the loop b ac k jac k as shown in Fi g u re  3 6
.
1. To install the loop b ac k jac k, simp ly d isc onnec t the RJ-48 (8-wide) 
c onnec tor (typ ic ally an H600-383 c ab le) at the app rop riate interfac e p oint 
and  c onnec t the loop bac k jac k in series with the DS1 sp an. 
See Fig ure 34
 throug h Fi g u re  3 8.
2. Plug  the H600-383 c ab le from the ICSU into the female c onnec tor on the 
loopback jack.
3. Plug  the male c onnec tor on the loop b ac k jac k c ab le into the network 
interfac e point.
NOTE:
Do not remove the loop b ac k jac k after installation. This is not a test 
tool and  should  always b e availab le to remotely test a DS1 sp an.
Without a Smart Jack
Install the loopb ac k jac k at the p oint where the c ab ling  from the ICSU p lug s into 
the d umb  b loc k. If there is more than one d umb  b loc k, c hoose the one that is 
c losest to the Interfac e Termination feed  or the fib er MUX to p rovid e maximum 
c overag e for loop b ac k jac k tests. Refer to Fig ure 37
 and  Fi g u re  3 8.

Administering the Loopback Jack
1. At the management terminal, enter change DS1 location. 
Location is the DS1 interfac e c irc uit p ac k c orresp ond ing  to the loop bac k 
jac k.
2. Be sure the near-end CSU
 typ e is set to integrated
.
3. On p ag e 2 of the form, c hang e the supply CPE loopback jack power 
field
 to y
. 
Setting  this field  to y
 informs the tec hnic ian that a loop b ac k jac k is p resent 
on the fac ility and  allows the tec hnic ian to d etermine that the fac ility is 
availab le for remote testing .
4. Enter save translation
 to save the new information.
Loopback Testing with a Smart Jack
The loop b ac k jac k and  smart jac k isolate faults b y d ivid ing the DS1 sp an into 3  
sec tions (see Fig ure  34
, Fi g u re  3 5, and  Fi g u re  3 6):
n
From the 120A2 (or later) ICSU to the loop b ac k jac k
n
From the loop b ac k jac k to the smart jac k (network interfac e
point)
n
From the smart jac k to the CO
The first 2 sec tions are your resp onsib ility. The last is the resp onsib ility of the DS1 
service p rovid er. 
Testing the DS1 Span from the ICSU to the 
Loopback Jack
The DS1 sp an test has 2 p arts. 
n
Chec king  for c irc uit c onnec tivity
The first p art of the test p owers-up  the loop b ac k jac k and  send s a sig nal 
from the DS1 c irc uit p ac k, throug h the wiring , to the loop b ac k jac k. The 
test allows ab out 10 sec onds for the sig nal to loop around  the loop b ac k 
jac k and  return to the DS1 c irc uit pac k. Then it send s the results to the 
management terminal and proceeds to the second part of the test.
n
The sec ond p art of the test send s the standard , 3-in-24 DS1 stress-testing  
p attern from the DS1 b oard , throug h the loop bac k jac k, and bac k to a b it 
error d etec tor and  c ounter on the DS1 b oard . A b it-error rate c ounter 
d isp lays the results on the manag ement terminal until you  terminates the 
test.
Always p erform b oth p arts of the test. Proc eed  as follows.

Checking the integrity of local equipment
Before you g o any further, make sure that the the p roblem is ac tually on the DS1 
sp an b y testing  the eq uip ment that c onnec ts to the sp an at the near end . 
1. Test the DS1 c irc uit p ac k, and  p erform any need ed  maintenanc e or 
rep airs. 
2. Test the ICSU, and  p erform any need ed maintenanc e or rep airs. 
Busying out the DS1 circuit pack
Now take the DS1 c irc uit out of servic e. 
1. Onc e you are sure that the DS1 c irc uit p ac k and  ICSU are func tioning  
c orrec tly, g o to the manag ement terminal, and  b usy out the DS1 c irc uit 
pack by entering 
busyout board 
UUCSS 
where 
UU is the c abinet numb er, C is the  c arrier number, and  SS is the 
slot number of the DS1 b oard .
Administering the DS1 for the test
1. At the manag ement terminal, op en the DS1 ad ministration form. Enter 
change DS1 
UUCSS
where UU is the c abinet numb er, C is the  c arrier number, and  SS is the 
slot number of the DS1 b oard .
2. Make sure that the near-end csu type
 field  is set to integrated
.
3. Chang e to p ag e 2 of the DS1 ad ministration form, and  c onfirm that the 
value of the TX LBO
 field is 0dB
. 
4. If the value of the TX LBO
 field  is not 0dB
, rec ord  the c urrent value. Then  
set the TX LBO
 field  to 0dB
 for testing. 
5. Press 
EN TER to make the c hang es, CANCEL to q uit without c hang es.
Testing the integrity of the loopback circuit
Now perform the first p art of the ac tual loop b ac k test.
1. At the management terminal, enter 
test DS1-loop 
UUCSS cpe-loopback-jack
 
where 
UU is the c abinet numb er, C is the  c arrier number, and  SS is the 
slot number of the DS1 b oard .
The loop b ac k jac k p owers up.  Ac tive, DS1 fac ility alarms (if any) c lear.   
After ab out 20 sec ond s, the first set of results ap p ears on the terminal.

b etween the ICSU and  the loop b ac k jac k or the loop b ac k jac k may itself 
be faulty. Isolate the problem by replacing the loopback jack and 
repeating step 1
. 
3. If FAIL

test, c hec king  the integ rity of transmitted  d ata.
Testing the integrity of data sent over the loop
Now perform the sec ond  p art of the test, c hec king for d ata errors. 
NOTE:
The loss of sig nal (LOS) alarm (demand  test #138) is not p roc essed  
d uring  this test while the 3-in-24 p attern is ac tive.
