24 Operating manual Pocket ISDN-TA
Call number display:
< rn > = call number of remote site
In AT command mode, call number display (does not belong to the AT command
standard) can be turned on by issuing the command ATV2 or ATV3. If turned on,
the call number of the caller is shown with the Connect- or Ring-message (in
pointed brackets), depending on the signaling in D-channel.
If the POCKET ISDN-TA is used at the public network then the call number of the
remote site (including area code) is displayed.
Example: CONNECT 64000 <040890880>
Error cause display:
< xx > = ISDN release (error) cause, hexadecimal
Example: NO CARRIER <#34F0>
In AT command mode, error cause display (does not belong to the AT command
standard) can be turned on by issuing the command ATV2 or ATV3. The shown
error causes use the coding defined by the CAPI definition. ISDN error causes from
the ISDN network are always coded as 34xxH, where xx represents the
hexadecimal version of the ISDN error cause (see page 30). All other causes are
CAPI error causes (see page 32).
4.2 ISDN access control
Using these commands you can setup a table, to allow only dedicated callers to
get a connection to the POCKET ISDN-TA.
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 beginning
at the last digit and is stopped when the shorter number is completely compared.
acctab
x nn/ss set entry number x to ISDN number nn and subaddress ss
acctab x - clear entry number x
acctab x * allows all incoming calls to be accepted
acctab x shows entry number x
acctab shows 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
