Installing and testing the splitter

The splitter must be installed and tested before the upgrade and cutover. The purpose of testing the splitter is to

■Prove that there is enough signal level for the cable length to the ATM switch:

—up to 130 ft. (39.65 m) for 400A

—within the standard 6 dB allowable loss for 401A, 402A, and 403A (see Table 3-3)

■Ensure that the DS1 circuit pack functions properly while receiving the DS1 signal level output from the splitter (Ports J1 and J2 unterminated).

Table 3-7 shows the configurations of the test cable and ports on the sync splitter.

Table 3-7. Cable and port configurations for splitter tests

To test	Description
Port J1	Insert an opening plug into port J2
Port J2	Insert an opening plug into port J1
Maximum output of the splitter	Insert an opening plug into both ports J1 and J2
to the DS1 circuit pack

Splitter port tests (401A/401A only)

NOTE:

The standard RJ45-to-Bantam test cable does not work with the 403A.

To test the splitter ports J1 or J2, use the procedures in Table 3-8, using the RJ45 to Bantam Test cable from the 1541CC cable kit.
