Held call clearing
No software changes are required to support this functionality on the XDID/
DOD cards.
Unequipped channel notification
To support this functionality, a channel download message is sent to the
XDID pack whenever a trunk on the pack is removed.
Call blocking
Before disabling a trunk, the software requires confirmation that the trunk is
in the idle state. To support this functionality, the software disable sequence
has been modified. The software waits for an idle state message from the
XDID pack before sending a disable message to the trunk. If the idle message
is not received before the disconnect supervision (DSI) timer expires, the
software prints the TRK136 (Release Failure on the Unit) error message. The
trunk is placed in lockout state. If the disable sequence was started from an
overlay, a TRK520 (No Far End Release) error message is printed. The trunk
remains in lockout until a Far End Release message is received on the pack.
Number Reception message
This is a Dutch Central Office (CO) requirement. When sufficient digits are
received at the Dutch CO, the battery is reversed. When the Dutch COT/DID
pack (NTAG04AA) detects this reversal, it sends a Number Reception
message. This functionality is a software enhancement.
Card Reset. When an ENLC command is performed on an XDID/E&M card,
the card is first reset and then messages are downloaded to the firmware to
reflect the software trunk state. This prevents the software database from
being in conflict with the firmware database. If an XDID/E&M card unit is in
busy state, the SSD message H.A004 is printed. If the unit is in barred state,
the SSD message H.A003 is printed.
