+## Specification
+D2Sphere SFAL TCP connector incommig message
+```
+$<sfal.data key1='value1' key2='value2' keyX='valueX'>" CRLF
+$ .... CRLF
+$<end> CRLF
+```
+additional key value will be handeled as well for following SFAL data frames
+```
+$<sfal.data key1='value1' key2='value2' keyX='valueX'>" CRLF
+...
+$<sfal.pos key1='value1' key2='value2' keyX='valueX'>" CRLF
+...
+$<sfal.event key1='value1' key2='value2' keyX='valueX'>" CRLF
+...
+$<sfal.*** key1='value1' key2='value2' keyX='valueX'>" CRLF
+```
+
+PFAL to send key value to server
+```
+$pfal,Tcp.Client.send,0,"<sfal.data key1='value1' key2='value2' keyX='valueX'>"
+```

+## Idea
+
+- Service type (4G LTE/UMTS...)
+
+- Received Bytes
+
+- SignalLevel (RSSI)
+
+- Sent Bytes
+
+- SNMP Contact
+
+- SNMP Description
+
+- SNMP Location
+
+- SNMP Router name
+
+- Uptime
+
+- SNMP interface details for all interfaces: 
+
+    - Up/down status(admin/operational),
+
+    - interface description,
+
+    - incoming traffic & errors
+
+    - outgoing traffic & errors
+- Packet loss through 5 ping tests
+
+- Simple Ping availability through 5 retries
+
+- Avg response time over 5 pings
+
+- CPU Load
+
+- RAM
+

+- Network interface details for all interfaces: 
+
+    - Up/down status(admin/operational),
+
+    - interface description,
