Stratum 3 Clock 
The Stratum 3 c loc k is an op tional feature for dig ital frame timing  that c oup les the 
c loc k outp ut to loc al c loc ks. This c hap ter p rovid e information on setting  the 
op tion switc hes on the c loc k. For installation information refer to the ap p rop riate 
installation or up g rad e b ook for your system.
Set Clock Options
There are four sets of op tion switc hes on the c loc k. Proc eed  as follows.
1. Set the options on the c loc k inp ut b oard  (CI) p er Ta b l e  1 7
.
 
2. Set the options on the Stratum 3 Clock board (ST3) per Tab le 18.

The H600-307 c ab le c onnec ts the system end of the Y-c ab le to a DS1 c irc uit 
p ac k (shown as TN464 or TN767E). The B25A c ab le c onnec ts the c loc k end  of 
the Y-c ab le to the yellow field  c ross-c onnec t.
Stratum 3 Clock Wiring Installation Procedure
1. Connec t the B25A c ab les from the TN780 c onnec tor panel slot on the 
system c ab inet and  the Stratum 3 Cloc k to the c ross-c onnec t mod ule in 
the yellow field .
2. Connec t the CSU p lug  end  of the H-600-274 Y-c ab le to the p rimary CSU. 
Route an H600-307 c ab le from the DS1 c onnec tor panel slot on the 
system c ab inet to the c onnec tor on the SYSTEM  e n d  o f  t h e  Y- c a b l e .
3. Route a B25A c able from the CLOCK end of the Y-c ab le to the c ross-
c onnec t mod ule in the yellow field .
4. Rep eat steps 2 and  3 for the sec ond ary CSU. The maximum allowab le 
c ab ling d istanc e b etween the Stratum 3 c loc k and  the CSU is shown in the 
table below.
5. For stand ard  reliab ility systems, refer to Y-c ab le to c ross-c onnec t the 
TN780 and  “ CLOCK”  end  c onnec tions to the Stratum 3 c loc k c onnec tions 
on the c ross-c onnec t mod ule.
6. For hig h or c ritic al reliab ility systems, refer to  tab le b elow to c ross-
c onnec t the TN780 and  “ CLOCK”  end c onnec tions to the Stratum 3 c loc k 
c onnec tions on the c ross-c onnec t mod ule.
