The codes defined for the sub-options are:
Opt Description of sub-option
01 Call server or 1 address PBX
02 Call server or 2-address PBX
03 Downloading server
10 Vlan 8021P
Note : Some DHCP servers in Windows 2003 Server no longer accept option code "01" which had
been defined for the Call Server or PBX's main address. To solve this problem, the options
are processed as "modulo 64" by the sets.
The "Call server or 1 address PBX" and Vlan 8021P sub options must be declared to start i7xx range
sets.
The "Call server or 2-address PBX and "Downloading server" sub-options are optional.
Sub options are encoded in ASCII.
Procedure:
In the main screen of the DHCP Server application:
• Right-click the line that corresponds to the DHCP server,
• Select Predefined options in the pop-up menu,
• In the next screen, Set Predefined options, select the option class required.
