Testing Wiring Without a Digital Port Tester

If you do not have a digital port tester, you can partially test the wiring at the equipment room wiring block. To this purpose, complete one of the following procedures:

1.Set the meter at 200v direct current (DC), and measure receive to transmit. A measurement of -48v indicates a normal reading; a measurement of +48v indicates that the power is reversed. If the reading is normal, go to the next step.

NOTE:

A reading of +5v indicates that the RC is busied out.

2.Busy out the RC, back it out, and then test for continuity. Measure the receive tip and ring; then measure the transmit tip and ring. If receive is 0.5 ohms greater than transmit, the pairs are polled properly.

Measuring Auxiliary Power

You cannot measure power at the WFB from the equipment room. To measure this, go to the WFB and measure punchings 7 and 8 at the 103 connector block. Consider the white/brown pair going to the WFB.

IROB WFBs

An in-range out-of-building (IROB) WFB requires that you extend the Category 3 twisted pair cable between buildings on a customer’s campus or premises. To do so, follow these guidlines.

■If the local electrical code in the area of the customer’s premises allows out-of-building, in-conduit telephone cable to be installed without protection, the technician can install the cabling without any protection.

■If the local electrical code for the customer’s premises requires protection on out-of-building, in-conduit telephone cable, the cabling must be installed with both primary and secondary protection.

Primary protection is defined as carbon blocks, gas tube protection, or a combination of both as prescribed by the local electrical code in the customer’s area.

Secondary protection is defined as a 146E IROB protection device. Two devices per circuit are required, one in each building. A circuit is the connection between one WFB and one port of the RC.

These devices must be ordered and provisioned locally by the wiring team. The local wiring team will be consulted to determine the local or national electrical code cable protection rules that apply at their customer’s premises.

■The 48-volt power supply must be located in the same building as the WFB. The 48-volt power cannot be sent over the out-of-building span.
