Cause codes for SS7 ASGCP calls to the TAOS unit
The TAOS unit reports cause codes to the signaling gateway via ASGCP when it initiates a call
clearing. The following ASGCP messages carry cause code information.
• Disconnect
• Release
• Release Complete
• Restart Acknowledgement (cause optional)
• Status
The TAOS unit currently reports the cause codes defined by ITU-T Recommendation Q.850.
For definitions of the individual cause values, refer to Q.850. Note the following:
• The TAOS unit reports Normal call clearing (16) if a TAOS unit modem times out on a
modem call.
Output field Description
Number of memory
allocation failures
Number of times the TAOS unit could not allocate
memory for packets traveling between call control and
layer 3.
These errors might occur if the TAOS unit does not have
a 32-MB DRAM card installed.
Number of errors in
profile operations
Number of times the TAOS unit could not register the
SS7-Gateway profile or read or update a T1 profile.
Number of invalid memory
pointers
Number of empty packets received by IPDC layer 3.
Used for IPDC only.
Number of internal errors
Number of internal errors.
Number of errors in
initialization
Number of errors that occurred during the initialization
of the SS7 ASG interface.
Memory pools
Number of buffer pool allocations that failed.
Mailboxes
Number of failures that occurred during the creation or
operation of the mailboxes used for interlayer
messaging.
