IP signalling flow charts…

2. SIP_SPC
SIP_SPC is the Extension Software for DS200 IP. Therefore, all of the IP Phones must register to SIP-SPC to start communicating
Stored in CF Memory in CPU4-MB
ETH0 Port is used to communicate with SIP_SPC
Protocols supported : TCP, UDP, TLS
Instant Messaging
Codec Information required for the call
Signalling bridge between Master and MGW2
KTS Signalling between Master and IP Extensions

15. OFFLINE IM Database Server:
Works with PC (Windows, Linux OS), PPC(CPU4), DS200L systems.
Database server communication is IP based.
Database size, IP address, the storage size limit for message deletion is configured by KNE program on SIP_SPC.

16. MGW1 IS SWITCHED-ON status MGW1 CARD MASTER MGWDAT messages
Card info is sent to MASTER
So, MASTER understands type of card
with that status message

MGWDAT messages can be seen from system log
These MGWDAT messages includes MAC address,
IP address, Gateway, Subnet mask, Codec info and RTP start & end port information of MGW1 card

Loader Service
MGW2 CARD
SIP_SPC
(4)

18. MGW2 IS SWITCHED-ON
MGW2 sends “status” message to MASTER in order to introduce it self.
MASTER determines “id” of DSP chips i.e Module No:1, DSP No:1, SlaveTbl[4].mgw2_dsp[0].id, ID No: Module No:1, DSP No:2, SlaveTbl[4].mgw2_dsp[1].id, ID No:1
MGW2 introduce itself to Loader Service and asks for firmware. Then MGW2 downloads firmware by TFTP server. At last, MGW2 informs MASTER that firmware download operation completed.

19. MGW2 IS SWITCHED-ON
After download operation, “update message” (upcx message) is needed by MASTER in order to start MGW2 card. Update messages between MGW2 & MASTER are transmitted via SIP_SPC i.e. REQ: MGW_UPCX Mgw-Ip: Mgw-Port: 0 BlfDsp-Id: 1 Pcm-Id: 0 Ch-Id: 1 // (MASTER to MGW2) IND: MGW_UPCX 200 => MGW2 Update OK Mgw-Port: 0 BlfDsp-Id: 1 Pcm-Id: 0 Ch-Id: 1 //(MGW2 to MASTER)
After “MGW2 Update OK” message, MGW2 is ready to use.

20. MGW2 IS SWITCHED-ON
LED Status of MGW2 Card from IDEA Configuration Menu;
At first when you first switched-on the card leds of MGW2 will be turned-off from IDEA configuration menu. (1) from diagram / slayt2
After software download operation, LED will be dark green (But it does not mean that MWG2 is ready to use, although the firmware is downloaded. (3) from diagram / slayt2
When SIP_SPC transmits update message to MGW2, LED becomes light green. Thus, MGW2 is ready to use.

21. MGW2 IS SWITCHED-ON LED Status of MGW2 Card on Module (h/w)
At first when you first switched-on the DSP LED blinks red. While blinking red, you can connect the module by KNE in order to adjust network settings if necessary.
Then LED blinks orange while downloading firmware from loader service through tftp server.
If download operation finishes successfully, the LED will blink green. Note:The led can blink green even though SIP_SPC is not working. Proper SIP_SPC is a must for usage of MGW2, since messages between MGW2 and MASTER are transmit over SIP_SPC.

Logs are saved into the PC on which IDEA program runs.
Running IDEA program is mandatory for saving logs .
CPU4 (New)
Logs are saved into CPU4 Card memory. %60 of the flash card can be used for logs.
No need to run IDEA program for saving logs, system automatically saves the logs into the memory of CPU.
