AEFR : Assignment of EPN Facility Restriction Data
AEFR: Assignment of EPN Facility Restriction Data
1. General
This command assigns the allowable connections among the RSC1 (Calling Party’s Restriction Class) and
RSC2 (Called Party’s Restriction Class).
2. Precautions
1. Data can be entered on a Day/Night basis, if specified in ASYD command, SYS1, INDEX75, Bit 4=1.
2. The applicable tenant number (TN) range is designated by the ASYD command, SYS1, INDEX8. If data
for this command is common for all tenants (ASYD command, SYS1, INDEX94, bit1=1), assign the TN
parameter as data “1” for all tenants.
3. The RSC1 (Calling Party’s Restriction Class) and RSC2 (Called Party’s Restriction Class) of each station
is assigned by the RSC parameter of the ASDT command.
4. The RSC1 (Calling Party’s Restriction Class) and RSC2 (Called Party’s Restriction Class) of each trunk
route (RT) is assigned by the trunk restriction class (TRSC) parameter of the ARTD command.
5. Before this command is assigned, connections for RSC1 (Calling Party’s Restriction Class) and RSC2
(Called Party’s Restriction Class) are not restricted.
6. Enter data “1 (Connection is allowed)” at the allowable connection of RES parameter. Once data has been
assigned on this command, the rest of connections become “0 (Restricted).”
7. If you want to recover the RSC1 (Calling Party’s Restriction Class) and RSC2 (Called Party’s Restriction
Class) connections, enter data “0 (Restricted)” for all connections.
8. The DNU = 3 (Urgent Mode) is used for LCR - Controlled Alternate PRSC service which works with the
ASYD command SYS1, INDEX59, bit1=1. The RSC2 of this command is referred to as the Priority
Restriction Class (PRSC) which is assigned by the AOPR command, or the TRSC parameter of the ARTD
command, depending on the system mode. When the urgent mode is launched by either the FRL key of an
Attendant Console or the CPRS command, the PRSC parameter of the AOPR command is carried out as
the outgoing call restriction matrix assigned by the AEFR command. When the urgent mode has
terminated (meaning that either the Day or Night mode has resumed), the outgoing call restriction is
referred to by the TRSC parameter of the ARTD command.
