# Referencing the CDI manager for Natural Access

For the CDI manager component to be available to the Natural Access server when it boots, the CDI manager must be referenced in the Natural Access configuration file, cta.cfg, as shown below:

[ctasys]
Service = ncc, adimgr
Service = adi, adimgr
Service = cdi, cdimgr
Service = ais, aismgr
Service = dtm, adimgr
Service = ppx, ppxmgr
Service = swi, swimgr
Service = vce, vcemgr
Service = oam, oammgr

For more information about cta.cfg and its contents, refer to the Natural Access Developer's Reference Manual.
