Cabling the Stratum 3 clock
Figure 38 shows typical connections to a Stratum 3 clock cabinet. Connections
are made through the yellow field cross-connect. A custom Y-cable (H600-274)
connects the CSU to the DS1 circuit pack and taps off the input for the Stratum 3
clock. A resistor built into the cable to provides the necessary isolation between
the system and the clock. The Y-cable plugs directly into the CSU and connects to
standard cables for interface to the system and the yellow field on the MDF.
The H600-307 cable connects the system end of the Y-cable to a DS1 circuit pack
(shown as TN464F or TN767E). The B25A cable connects the clock end of the
Y-cable to the yellow field on the MDF.
