# ACL Entries
#
# The 'action' May be PERMIT|DENY
# Each entry may be a single radio id, a hypenated range (e.g. 1-2999), or the string 'ALL'.
# if "ALL" is used, you may not include any other ranges or individual IDs.
# Format:
# ACL = 'action:id|start-end|,id|start-end,....'
#
# Sections exist for both TGIDs and Subscriber IDs.
# Sections exist for glboal actions, and per-system actions.
# ***FIRST MATCH EXITS***
# SID - Subscriber ID section.
# TGID - Talkgroup ID section.
#
# "GLOBAL" affects ALL systems
# "SYSTEM NAME" affects the system in quetion
# ACLs are applied both ingress AND egress
# If you omit GLOBAL or SYSTEM level ACLs, they will be initilzied
# automatically as "PERMIT:ALL"
# Each system (or global) has two sections 1 and 2, which correspond
# to timeslots 1 and 2 respectively
#
# EXAMPLE:
#ACL = {
# 'SID': {
# 'GLOBAL': {
# 1: 'PERMIT:ALL',
# 2: 'PERMIT:ALL'
# },
# 'LINK': {
# 1: 'DENY:3120121',
# 2: 'PERMIT:ALL'
# }
# },
# 'TGID': {
# 'GLOBAL': {
# 1: 'PERMIT:ALL',
# 2: 'PERMIT:ALL'
# },
# 'LINK': {
# 1: 'DENY:1-5,1616',

# of the Brandmeister team as a way to legitimately connect HBlink to the
# Brandemiester network.
# It is recommended to name the system the ID of the Brandmeister server that
# it connects to, but is not necessary. TARGET_IP and TARGET_PORT are of the
# Brandmeister or IPSC2 server you are connecting to. PASSPHRASE is the password
# that must be agreed upon between you and the operator of the server you are

# will be sent to the other server to identify this connection.
# other parameters follow the other system types.
