Built-in ISDN control firmware supports all the

 

 

 

functions necessary for setup and configuration of

 

 

 

the terminal adapter and the ISDN line. Configur-

Unlike RS-232, these pins have TTL level re-

command set, a menu-driven setup utility, or

Flash Memory is designed to support custom

 

 

 

control program downloading. By changing a

 

 

 

configuration pin, the XEISDNU5 can boot-up

 

 

 

from the ISDN Monitor or a user developed

 

 

 

program as well as the built-in ISDN control

 

 

 

program.
