Technically Speaking

Light-emitting diodes (LEDs) display the status of certain operating functions and will indicate if malfunctions are occurring.

Keep these guidelines in mind when observing the NTU-1’s LEDs:

If a disruption occurs between the U interface and the ISDN switch, the ACT LED flickers.

If a disruption occurs between the S or T interface and the TE, the ACT LED blinks once per second.

If a disconnect occurs on both interfaces, the ACT LED goes out.

The NTU-1’s six LEDs are:

LP (Local Power)—ON indicates the wallmount transformer is plugged in, and 120 VAC is present.

RB (Remote Power)—ON indicates the remote power source is connected and functional.

RPR (Remote Power Reversed)—ON indicates the remote power source is connected, but polarity is reversed. This must be corrected by site facilities.

LB (Loopback)—ON indicates that the telephone company’s ISDN switch has sent a 2B+D loopback command to the NTU-1.

SC (Sealing Current)—ON indicates a presence of metallic termination test voltage from the ISDN switch.

ACT (Activity)—ON indicates that a link-up between the TE and ISDN Central Office via the NTU-1 has been achieved, and transmission can take place.

Why Buy From Black Box? Exceptional Value. Exceptional Tech Support. Period.

Recognize any of these situations?

You wait more than 30 minutes to get through to a vendor’s tech support.

The so-called “tech” can’t help you or gives you the wrong answer.

You don’t have a purchase order number and the tech refuses to help you.

It’s 9 p. m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—and certainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the

best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.

Don’t waste time and money—call Black Box today.
