ODS2 DISTRIBUTION SYSTEM AND QFLC/QLX CHASSIS END-TO-END TESTS
Summary:
This procedure provides instructions for performing end-to-end system tests on the
equipment in a Soneplex ODS2 distribution system to an QFLC or QLX chassis. Two telephone
technicians may be required to perform this test, one at the near end and one at the far end of the
system. The installation must be complete and the equipment operating properly. If you are
unfamiliar with the Craft Interface system, refer to the Task Index List (IXL-001) found earlier
in this manual.
Caution:
Modules can be damaged by electrostatic discharge (ESD). Before handling
any modules, ESD protection must always be used. Ensure that all modules removed
from the chassis or not installed are properly stored in anti-static packing material.
When working with modules, always place the module on an electrically-grounded,
approved, anti-static mat.
1. The following tools and equipment are required to perform this test:
• Anti-static wrist strap
• DS3 digital transmission test set with DS1 option
• DS1 digital transmission test set
• Patch cords to connect test sets and patch panel
2. At the chassis location, connect a DS3 test set, with DS1 option to the DSX-3 cross-connect
or to the DS3 RX and TX connections at the rear of the chassis. See Figure 510-
1.
3. Identify the ODS2 working and protect pair corresponding to the DS1 circuit to be tested.
4. Identify the remote QFLC or QLX working and protect pair corresponding to the DS1
circuit to be tested.
5. At the QFLC or QLX location, connect DS1 test set to the DS1 circuit to be tested at the
QFLC or QLX DS1 input and output connections, the DS1 patch panel, or at the DSX-1.
See Figure 510-1.
6. At both ends of the circuit to be tested, make necessary cross-connects so that both ends of
the circuits are connected end-to-end.
7. Using the Craft Interface, verify that the DS3 MUX is EQUIPPED and IN SERVICE.

8. Using the Craft Interface, verify that the ODS2 module to be tested is EQUIPPED and is IN
SERVICE and the DS1 to be tested is PROVISIONED and IN SERVICE.
