Assembly and Installation

Connecting the Handset and Headset

1. Using the provided 9-foot coiled handset cord, insert one end into the jack in the bottom of the

handset. Insert the other end into the jack on the back of the phone console labeled with the

handset icon as shown in Figure 3. Place the handset on the handset cradle once installed.

2. Optional. Connect your headset to the jack in the back of the phone console labeled with the

headset icon as shown in Figure 3. There are many types of headsets that can be used with the

IP 706 or IP 712 phone. For a list of compatible headsets for the IP phones, refer to the ADTRAN

website at www.adtran.com/phones. Once the headset is connected, the headset feature is ready to

use.

The pinout for the optional headset is available in Table 1 below. Refer to ADTRAN's Knowledgebase at

http://kb.adtran.com/article.asp?article=3059&p=2 for a list of wireless headsets that have been approved

for use with ADTRAN IP 700 Series phones.

Off-hook detection is achieved by providing battery across the TX+ and TX- pair and monitoring for loop

current. You can simulate off-hook by connecting a 1.5 k resistor across these pins.
