# 5560 IPT Master/Slave Association

## Purpose

This form allows you to associate the DN of the master phone with the DN of the slave phone.

5560 IPTs are typically used in financial institutions by stock traders and allow users to handle two calls at the same time. From a user's perspective, the 5560 IPT is a single console with two handsets that allows the user to have two simultaneous calls in progress. The user presses the Left and Right keys on the 5560 IPT to switch the set operation between the left and right calls. While the lamp of the Left key is on, key presses affect the call on the left side; while lamp of the Right key is on, key presses affect the call that is on the right side.

From a programming perspective, the 5560 IPT consists of two separate phones in a single console -- one phone is designated as the master and the other as the slave. Any feature key programming or application settings that the user configures on the master phone are automatically copied to the slave phone, ensuring that the phones function identically. Any programming key changes that the administrator makes to the master directory number (DN) through the Multiline IP Sets form are synchronized with the slave DN by the 5560 IPT application.

Use this form to perform the following tasks:

- Program 5560 IPTs

## Conditions

- Before you can save a DN in this form, you must assign the "5560 IPT" device type to the DN in the Multiline IP Sets form.

- A DN can only appear once in this form.

- This form only associates the master DN with the slave DN. When you add or delete a directory number in this form, the system does not apply the updates to any other forms.
