Utility Commands

The following table describes the Utility Commands.

AT$C P=n Enable / disable compression.

AT$E X View Internal ExPrintf log buffer.
AT$In O n Demand SPID Testing (North America only). Lets you test SPIDs on demand.
n=<SPID Number>
Tests the specified SPID. To perform this test you must be connected to National ISDN
or AT&T 5ESS Custom interface. The test is only supported if neither logical channel is
initialized (either with a SPID or in NIT mode). If required, clear the SPID and disable NIT
mode for both channels, then reset the device. You can then run two SPID tests (further
tests will be rejected).
n=<blank>
Retrieves any AutoSPID data downloaded during location detection. Note that this
command does not initiate the AutoSPID procedure; it simply retrieves historical data.
The following string of information is displayed:
[SPID number, Directory Number, call type, error code]
Call type is indicted by the following codes: v=voice, d=data, p=packet.
Note: If AutoSPID cannot detect Directory Numbers and call types, these fields will be
empty. If an AutoSPID download has not been performed, no information will be
retrieved.
AT$IG SP ID guessing (North America only). Specifies that the DIVAT/A should attempt SPID
guessing. When the command is entered, the DIVAT/A will attempt to guess the SPID
for each B-channel. If SPID initialization is successful, the SPID number is displayed and
saved automatic ally.
If a datalink problem is encountered during SPID guessing, the guessing is aborted and
the message “No Carrier” is displayed.
