URC cause identifier.
0 An error has occurred after opening or while using an Internet service.
Error number is presented via <urcInfoId>, optionally additional information
may be supplied via <urcInfoText>.
1 Indicates that an opened Socket listener service is receiving a connection
request from a remote client.
The incoming socket connection is dynamically assigned to the next free Inter-
net service profile. In this case, the parameter <urcInfoId> inside the "^SIS"
URC equals the <srvProfileId> of the dynamically assigned service pro-
file. This ID shall be used to accept the connection request with AT^SISO or to
reject it with AT^SISC.
The connection status may be requested by using the AT^SISO read com-
mand. Among other details, the response indicates the IP address of the
remote client (parameter <remAddr>). This may be helpful to decide whether
to accept or reject the request.
2 Incoming Socket service client connection has failed.
The client request was rejected automatically because no free Internet service
profile was available.
3 HTTP only: Indicates that the message delivered by the "^SIS" URC is pro-
vided for information only, it is not an error. For details refer to Info URCs in
Section 10.7.3, URC Information Elements Related to HTTP Service.
Example: ^SIS: 2, 3, 2200, "HTTP Redirect to:192.168.1.3:800//products/info/"
Information identifier related to <urcCause>.
See Section 10.7, Information Elements Related to Internet Service URCs for further detail.
As stated above, if a Socket connection request from a remote client is received the <urcInfoId> equals the
<srvProfileId> of the dynamically assigned free service profile.
Information text related to <urcCause>.
See Section 10.7, Information Elements Related to Internet Service URCs for further detail.
Note
• In addition to the "^SIS" URC detailed Release Causes can be obtained with AT+CEER. See Section 3.4.1,
Cause Location ID for the extended error report and Section 3.4.15, SIEMENS release cause for IP over AT
