Synchronization Installation and Testing	3-26

To install a 400A sync splitter between a CSU or DSU/CSU and a DS1 circuit pack, follow the procedures listed in Table 3-13.

	9.	Test the splitter		Use the procedure in ‘‘Splitter port tests
				(401A/401A only)’’ on page 3-19.
				■ Before testing the splitter, insert a modular
				RJ45 plug into jack J1 and jack J2.

NOTE:

Do not connect port J1 to port J2. Leave the other end of both cords free, because the modular RJ45 plug acts as a opening plug and removes the 100-Ωtermination from J1 and J2 ports.

		■ After testing is complete, remove the
		opening plugs from J1 and J2.
10.	Check	After about 20 s, all the alarm LEDs on the 316X
