during unlocking of FMS or LLI, then all communication relationships remain re-
leased with the exception of the management connection.
Error Type
This parameter contains information on the reason the service failed.
Error CREF
This parameter specifies at which CREF the TerminateLoad-CRL-Loc service was
aborted. The existence of the parameter depends on the Error Type.
4.5.1.3.6 InitiateLoad-CRL-Rem
The remote writing into the CRL is done with a service sequence of InitiateLoad-
CRL-Rem, one or several Load-CRL-Rem and one TerminateLoad-CRL-Rem.

Argument
The argument contains the parameters of the InitiateLoad-CRL-Rem.req primitive
and the InitiateLoad-CRL-Rem.ind primitive.
Communication Reference
This parameter specifies the identifier of the associated management connection
in the CRL.
Result(+)
The Result(+) parameter indicates that the service was executed successfully.
Result(-)
The Result(-) parameter indicates that the service failed.
Error Type
This parameter contains information on the reason the service failed.
4.5.1.3.7 Load-CRL-Rem
The CRL header or the static part of a CRL entry is written remotely with the
Load-CRL-Rem service. The CRL header is written as a CRL entry with the communi-
cation reference 0. For writing the static part of a CRL entry the corresponding
CREF shall be set. The Load-CRL-Rem service shall be used repeatedly to write
the whole CRL.
