3-5 Synchronization Installation and Testing 
3
Installing  and  testing  the sync hronization sp litter involves interrup ting  the DS1 
sig nal p rovid ed  by the servic e p rovid er. Even thoug h the DS1 c irc uit p ac k should  
b e d own less than 5 minutes, b efore removing  a working  T1/E1 sp an, c ontac t the 
servic e p rovid er. Failure to notify the T1/E1 servic e p rovid er may result in:
— The servic e p rovider loop ing  the T1/E1 sp an b ac k to the 
sub sc rib er.
— A sp an alarm b eing  d etec ted  at the c entral offic e and  the sp an 
b eing  taken out of servic e, send ing  an AIS (b lue Alarm) to the 
DEFINITY ECS. The sync hronization sig nal is nec essary for testing 
eq uip ment and  c onnec tions.
Splitter descriptions 
Table 3-2 d esc rib es the 4 sp litter mod els and  their c ap ab ilities. The d rawings 
show the sp litters and their c onnec tion p oints. Figure 3-5
 shows a sc hematic  of 
the 2 jump er sets and  their c onnec tions for 401A, 402A, and  403A sync  sp litters.
