Configuring an SS7 signaling gateway
APX 8000/MAX TNT/DSLTNT Physical Interface Configuration Guide Preliminary May 9, 2000 18-17
Number of CONNECT to ASG
Total number of active connections to the signaling
gateway since it was last reset.
Number of CONNECT_ACK
from ASG
Number of connection acknowledgements the TAOS
unit has received from the signaling gateway.
Number of SETUP rejected
from:
Number of setup requests rejected by layer 3 and the
signaling gateway call control.
• Setups rejected by L3 indicate a packet decode error
on the incoming setup request.
• Setups rejected by CC can mean that no route or
resource exists, or that authentication failed for the
incoming call.
Number of DISCONNECT
requests from:
Number of disconnection requests from layer 2 and the
signaling gateway call control.
• Disconnection requests from layer 2 are initiated by
the signaling gateway.
• Disconnection requests from CC are initiated by the
TAOS unit.
Number of REGISTRATION to
ASG
Number of registration requests the TAOS unit has sent
to the signaling gateway.
Number of
REGISTRATION_ACK from ASG
Number of registration acknowledgments the TAOS unit
has received from the signaling gateway.
Number of DL_REL_IND from
L2
Number of Data Link Release Indication messages
received from layer 2. Layer 2 sends these messages to
layer 3 to inform it about the status of the link. Data Link
Release Indication messages mean that the link between
the TAOS unit and the signaling gateway is down and
communication is not possible.
Number of DL_EST_IND from
L2
Number of Data Link Establish Indication messages
received from layer 2.
Layer 2 sends these messages to layer 3 to inform it
about the status of the link. Data Link Establish
Indication messages mean that the link between the
TAOS unit and the signaling gateway has been
reestablished and communication is possible.
Number of T303 expiry
events
Number of times the T303 timer expired.
Number of T305 expiry
events
Number of times the T305 timer expired.
Number of T308 expiry
events
Number of times the T308 timer expired.
Last L3 counters reset
timestamp
Time the signaling layer timers were last reset using the
ss7asg -r command.
