Integrated Services Digital Network User Adaptation Layer can not Go
Active—Signaling (159)
The Integrated Services Digital Network User Adaptation Layer can not Go Active event serves as a
warning that no ACTIVE acknowledgement messages are being received from any signaling gateway.
This indicates that the ISDN signaling gateway or the SCTP associations are probably down. To correct
the cause of the event, investigate other alarms to see if the signaling gateways are down or to see if the
SCTP associations are down. Take corrective action according to the alarm indications.
Integrated Services Digital Network User Adaptation Layer can not Go
Standby—Signaling (160)
The Integrated Services Digital Network User Adaptation Layer can not Go Standby event serves as a
warning that no ACTIVE acknowledgement messages are being received from any signaling gateway.
This indicates that the ISDN signaling gateway or the SCTP associations are probably down. To correct
the cause of the event, investigate other alarms to see if the signaling gateways are down or to see if the
SCTP associations are down. Take corrective action according to the alarm indications.
Session Initiation Protocol Update not Allowed for Operator Service Position
System Calls—Signaling (161)
The Session Initiation Protocol Update not Allowed for Operator Service Position System Calls event
serves as a warning that the remote switch is not allowing the BTS 10200 to send SIP UPDATE
messages. The UPDATE messages are mandatory in the CMSS and are used exclusively by the BTS
10200 for operator service calls over SIP including BLV, emergency interrupt, and 911 ringback calls.
To correct the cause of the event, upgrade or re-provision the remote switch so it can process incoming
SIP UPDATE messages.

Service—Signaling (162)
The Session Initiation Protocol Server Group Element Operationally Out of Service alarm (critical)
indicates that the BTS 10200 is unable to communicate with a remote SIP party (call-agent or proxy)
over a SIP server group element. To troubleshoot and correct the cause of the Session Initiation Protocol
Server Group Element Operationally Out of Service alarm, refer to the
Server Group Element Operationally Out of Service—Signaling (162)" section on page
Routing Key Inactive—Signaling (163)
The Routing Key Inactive alarm (major) indicates that INACTIVE acknowledgement messages were
received from a Signaling Gateway. The SG or SCTP associations are probably down. To troubleshoot
and correct the primary cause of the Routing Key Inactive alarm, refer to the
Inactive—Signaling (163)" section on page
