Interface Control

Use the following procedure to set or change the interface control value.

NOTE: The 4601, 4602, and 4690 Telephones do not have Ethernet PC interfaces, so this procedure does not apply to those phones.

1. While the telephone is on-hook and idle, press the following sequence of keys on the faceplate of the telephone:

Mute 4 6 8 # (Mute I N T #)

NOTE: Press the Mute button momentarily. Do not press this button while pressing other keys/buttons. The 4630 and 4630SW IP Telephones do not have a dedicated Hold button. For all other 4600 Series IP Telephones, pressing the Hold button instead of the Mute button also works.

2. For telephones that support an Infrared (IR) interface (4620 and 4620SW only), proceed directly to Step 7. If the telephones have an internal Ethernet switch, proceed to Step 3.

After entry of the command sequence, telephones with an internal Ethernet switch display the following text, depending on the current interface control value:

where status is the value of PHY1STAT, defined as:

• Status is auto when PHY1STAT = 1
• Status is 10Mbps HDX when PHY1STAT = 2
• Status is 10Mbps FDX when PHY1STAT = 3
• Status is 100Mbps HDX when PHY1STAT = 4
• Status is 100Mbps FDX when PHY1STAT = 5
3. To change the PHY1 value, press *.

Depending on the current value, the next sequential valid PHY1 value is selected and displayed as the status. For example, if the current value is 10Mbps HDX (2), pressing * changes the value to 3 (10Mbps FDX). If the current value is 100Mbps FDX (5), pressing * changes the value to 1 (auto).

If a value different from the current PHY1STAT value is entered, the following text displays left-justified at the top of the display:

4. Press the * button to terminate the procedure, or the # button to save the new value. If you press the # button, the following text displays:

where status is the value of PHY2STAT, defined as:

• Status is disabled when PHY2STAT = 0
• Status is auto when PHY2STAT = 1
• Status is 10Mbps HDX when PHY2STAT = 2
• Status is 10Mbps FDX when PHY2STAT = 3
• Status is 100Mbps HDX when PHY2STAT = 4
• Status is 100Mbps FDX when PHY2STAT = 5
5. To change the PHY2 value, press *.

Depending on the current value, the next sequential valid PHY2 value is selected and displayed as the status. For example, if the current value is 10Mbps HDX (2), pressing * changes the value to 3 (10Mbps FDX). If the current value is 100Mbps FDX (5), pressing * changes the value to 0 (disabled).

The following text displays left-justified at the top of the display:

6. Press the * button to terminate the procedure, or the # button to save the new values.
   If you press the # button, the following text displays.

The new values are saved and a restart occurs automatically. The user interface is restored to its previous state.

7. For telephones with an IR interface, after entry of the command sequence, one of the following texts displays, depending on the current value of the IRSTAT:

8. Press the 1 or 0 button to enable or disable the IR interface respectively, or press the # button to leave the current value. The following text displays left-justified at the top of the display:

9. Press the * button to terminate the procedure, or the # button to save the new values.

If you press the # button, the following text displays.

The new values are saved, and a restart occurs automatically. The user interface is restored to its previous state.
