RLX (OR RLXIOR) AND REMOTE SYSTEM END-TO-END TEST PROCEDURES
Summary:
This procedure provides instructions for performing end-to-end tests between the
Version A or Version B RLX modules, or RLXIOR modules, and the remote system. Performing
an end-to-end test includes connecting the cross-connect jumper wires, and then sending a test
signal between the two systems. This procedure assumes that the T1 facility between the central
office and the repeater is functional, and that the RLX modules to be tested have already been
installed. This procedure must be performed before attempting to operate the entire circuit or
system that will be using this equipment.
Warning:
To prevent electrical shock, never install telephone equipment in a wet
location or during a lightning storm. When installing or modifying telephone lines,
disconnect lines on the network side before working with uninsulated lines or terminals
.
Caution:
Electronic modules can be damaged by electrostatic discharge (ESD). Before
handling modules, wear an anti-static discharge wrist strap to prevent damage to
electronic components. Place modules in anti-static packing material when transporting
or storing. When working on modules, always place them on an approved anti-static mat
that is electrically grounded.
Do Items Below in The Order Listed
For Details Go To
1. Obtain the following tools and equipment:
•
Anti-static wrist strap
•
DS3 test set with DS1 option (for central office end of the
circuit)
•
DS1 digital transmission test set (T-Berd 211 or equivalent)
•
VT-100 compatible terminal or computer with terminal
emulation software
2. Coordinate test with a technician located at the remote end of the
circuit and ensure test procedures there have been completed.
3. Open the chassis front cover.
4. Momentarily press the LMPTST switch on the APU front panel
and verify that all indicators light.
5. Connect terminal equipment to Craft port on the front of the MPU.
