changes to a - sign.

3. Select Scope->Create.

4. Define the range of IP addresses used by the IP telephones listed in Line 7 of Table 4-2.

The Start Address should be the first IP address to be used for the IP telephones.

The End Address should be the last IP address to be used for the IP telephones.

Subnet Mask should be set to the value as recorded in Table4-2.

Perform the following steps to exclude any IP addresses that you do not want to be assigned

to IP telephones within the range specified by the Start and End Addresses.

field under Exclusion Range.

■135.254.76.7 to 135.254.76.80

■135.254.76.90 to 135.254.76.200

■135.254.76.225 to 135.254.76.230

Your start address and end address should then be 135.254.76.7 and 135.254.76.230

respectively.
