The type8helper utility is only useful at sites that support System Release 2.2 or 3.2 
(SR 2.2/3.2) software. With the development of SR 2.5 and higher, the system assigns 
type-8 EMMs to a device automatically whenever the device is enabled for 
encrypted sessions. 

 

When it runs, the type8helper utility creates the following three working files: 

 

macRecent—Contains the MAC addresses of all recently staged, in-service, two-
way devices 

 

mac8—Contains the MAC addresses of all devices that already have type-8 
EMMs 

 

need_T8.txt—Generated by comparing the previous two files; contains the MAC 
addresses of devices for which type-8 EMMs were just generated 

 

The type8helper utility is designed to run from the crontab (cron) file on the DNCS. 
Programs that run from cron run automatically on a pre-defined schedule, without 
user intervention. When run from cron, the system regularly assigns type-8 EMMs to 
newly staged devices that lack type-8 EMMs. 

Our engineers recommend, however, that system operators run the type8helper 
utility manually the first time. The first time the utility runs, the system may have an 
inordinately large number of devices without type-8 EMMs. The utility is designed 
to seek user confirmation whenever it encounters more than 500 devices that lack 
type-8 EMMs, a condition the utility is unlikely to encounter when it is subsequently 
run from cron.
