Syntax of DHCP option 148

I have an omniswitch os9907 that is DHCP server for some networks.
The client has APs Huawei that need the following parameters:

network 10.150.209.0/24
default-router 10.150.209.254
domain-name ipn.mx
dns-server 148.204.103.2
option 148 hex 6167.696c.656d.6f64.653d.6167.696c.652d.636c.6f75.643b.6167.696c.656d.616e.6167.652d.6d6f.6465.3d69.703b.6167.696c.656d.616e.6167.652d.646f.6d61.696e.3d31.302e.3230.342e.3137.392e.363b.6167.696c.656d.616e.6167.652d.706f.7274.3d31.3030.3230.3b61.702d.6167.696c.656d.6f64.653d.6167.696c.652d.636c.6f75.643b

Can you help me to show me the syntax for option 148 in the dhcpd.conf file???

Thank you for your advise.
