Inbound SDU Failures
Potential SDU inbound failure codes are described below. The list
identifies all likely SDU failure responses. The remaining SDU
responses that appear in the NCL 1.2 reference manual are not
expected to occur within the DataTAC wireless modem.
Inbound SDU failure, no response from network
The SDU was transmitted, but not acknowledged by the network. The
SDU may have been delivered; the acknowledgment might have been
the element that could not be successfully returned to the originating
device.
Inbound SDU failure, host down
This failure indicates that the internal network connection to the
application host computer is currently unavailable. Because DataTAC
networks are designed with very high reliability, this failure is
extremely rare.
Inbound SDU failure, low battery
The SDU could not be delivered due to a low battery condition. When
a low battery condition is reached, the radio network connection is
dropped until the low battery condition is corrected. (This can be
addressed by replacing the battery or, if trickle charging is enabled,
waiting for a sufficient charge level to be reached.)
Inbound SDU failure, inbound queue full
This response indicates that the maximum number (2) of SDUs are
already queued within the wireless modem. Another SDU can be
submitted when the NCL response for one of the pending SDUs has
been returned.
Inbound SDU failure, out of range
The wireless modem has either lost network coverage or is in the
process of re-establishing network contact. See “Loss of Network
Contact” on the following page.
Inbound SDU failure, transmitter disabled
This SDU failure code indicates that the radio transmitter has been
disabled, under application control, within the wireless modem. The
transmitter must be enabled prior to submitting an SDU.
Note: This could be the result of transmitting a Receiver Disable
command to the wireless modem. This command requires both
Receiver Enable and Transmitter Enable commands to recover two-
way communications.
