60 4600 Series IP Telephone Release 2.2 Installation Guide
All IP telephones except the 4601 display the following text left-justified at the top of the
display:
where ddd is the value of NVCHADDR, the system variable for the DHCP Client Hardware
Address.
Because it does not have a display, the 4601 IP Telephone’s Call Appearance Line a’s
indicator winks out the current NVCHADDR value 600 milliseconds on, 200 milliseconds off.
If the current value is zero, Call Appearance Line a’s indicator flutters five times 50
milliseconds on, 50 milliseconds off instead of winking.
After the 4601 “displays” the current value, the Message Waiting indicator at the top of the
phone and the Message button LED on the faceplate flash 500 milliseconds on, 500
milliseconds off to indicate an entry is expected.
2. To change the Client Hardware Address value, enter a valid client hardware address. This
value is usually the MAC address, which DHCP then converts to an integer preceded by
zeroes.
The 4601 provides feedback for each digit as you enter it using both Call Appearance Line
indicators. The indicators alternate winking the number of times represented by the digit you
press 200 milliseconds on, 50 milliseconds off. For example, if the first digit of the address is
“2,” pressing the number 2 on the dial pad causes Call Appearance Line a’s indicator to
wink two times. If the second digit you press is “4,” after an 1800 millisecond pause, Call
Appearance Line b’s indicator winks four times. Pressing “0” (zero) on the dial pad causes
the appropriate indicator to flutter three five 50 milliseconds on, 50 milliseconds off.
Then the 4601 flashes both Message Waiting indicators 500 milliseconds on, 500
milliseconds off to indicate an entry is expected.
For all IP telephones except the 4601, if a value different from the current value of
NVCHADDR is entered, the following text displays left-justified at the top of the display:
3. Press the * button to terminate the procedure, or the # button to save the new value. If you
press the # button, all IP telephones except the 4601 display the following text:
All phones save the new value.
chaddr=ddd
