 That would then start the `rts-module@h1lsc.service` to load the kernel module, the `rts-epics@h1lsc.service` to start the EPICS IOC process, and the `rts-awgtpman@h1lsc.service` to start the awgtpman process.

 ### distributed front ends
 
 The various distributed front end transport mechanisms (available in separate `advligorts-transport-*` packages) also include service units.  The same package holds both the 'xmit' and 'recv' services and would be installed on both the front end and the data concentrator.  On the front end, to enable and start the 'cps' transport sender:
 ```shell
-# systemctl enable --now rts-cps_xmit.service

 On the data concentrator run:
