Regardless of your site’s phone configuration, you’ll need the following
equipment to install the ASD-4:
• One 7-ft. (2.1-m) telephone-line cable with male RJ-11 connectors at both
ends—This is provided with your ASD-4.
• Additional telephone-line cables with RJ-11C or RJ-13C connectors—You
will need additional telephone cables for as many pieces of equipment as
you intend to attach to the ASD-4. These cables are usually supplied by
the equipment manufacturer, or you can purchase them through Black
Box.
• Extension cables (optional)—If the equipment you want to attach to the
ASD-4 is not located near the unit, you might need extension cables.

We recommend that you use surge protection for all telecommunications
devices. The ASD-4’s power supply should be connected to a surge suppressor
and/or a line conditioner. Also attach in-line surge protectors to the
telephone line conected to the ASD-4. If you need surge-protection
equipment, contact Black Box.

conditions apply:

with rotary or pulse-dial extension phones.
• You want to use the ASD-4’s Open Line Notification feature with
extension phones.
