TS 32.422 — Subscriber and equipment trace; Trace control and configuration management⚓︎
Release: Rel 15 · Version assessed: 15.0.0 · Network: 4G · Applies to: MME
Optional capability, configured on request
The network function software implements this specification, and the statement below records that implementation. An Expeto deployment does not configure this capability by default and the acceptance test catalog does not cover it. If your deployment needs any part of it, contact Expeto Product Support: enabling it is configuration work that Expeto scopes and carries out with you.
Mandatory items: 29, of which 29 supported. A further 179 clauses of the specification carry no conformance requirement and are not listed.
