4.4 ISDN access control
Using these commands you can setup a table, to allow only dedicated callers to get a
connection to the IDW-90.
If this list is empty (default) or one entry is set to star (*), any incoming call is allowed.
Every incoming call that does not fit to one of the entries of acctab will be ignored. The
received calling party number is compared to every entry starting at the last digit and is
stopped when the shorter number is completely compared.
acctabx nn/ss set entry number x to ISDN number nn and subaddress ss
acctabx - clear entry number x
acctabx * allow all incoming calls to be accepted
acctabx show entry number x
acctab show all entries
Maximum number of entries = 5; x = 1..5
Maximum length of ISDN number = 20 digits
Maximum length of subaddress = 20 digits
The ISDN number nn can contain wildcards:
* : represents one or more digits
? : represents exactly one digit
Note: If a subaddress is set, the received calling subaddress must be identical to the
subaddress that is set.
Examples:
acctab1 1234567890 accept only specified number
acctab2 *456* accept all numbers with 456 somewhere in the middle
acctab3 ?2345678?? accept all numbers with 2345678 in the middle preceded
by one digit and followed by two digits.
acctab2 *1234/987 accept all numbers that end with 1234 and have the
subaddress 987
acctab3 * accept all incoming calls without subaddresses
acctab3 - clear entry no. 3
Note: If you are not sure in which format the calling number will be presented with an
incoming call, please use the command ATW1 to see the the format of the calling
number in the RING message. This number can be entered into the acctab.
