Well first the all MSTP products of ZTE can use OSPF protocol to route the monitoring management data to and from EMS. In doing so Agent (the software running in the NCP board, you can say this is the brain of the NE) assigns IP addresses to some of the opticals boards of the NE in order for OSPF protocol to be able to work propperly (please refer to some documents to learn about OSPF in ZTE equipments, you can find them by looking for ECC documents) so additionaly of the IP address you assign to the NCP, ergo the NE, also the NE will use IP addresses the will be in the same IP segment of the NCP address, in other words, if you assign contiguos IP addresses to different NEs their optical boards IP addresses might confilct with each other, so you can use the following formula for the IP address:
Area ID.NE number.NE number:18
Example: first 188.8.131.52, next NE 184.108.40.206, 220.127.116.11 and so on but never repeat the third octect of the IP address in any NE
For the routers I am afraid I cannot help you, you can configure them as you please but you need to make sure the IPs addresses of MSTP and datacomm equipments NEVER repeat or else you will have problems, you also need to make sure the access NEs monitoring packets (the data of QX port) can get to the server without problems, for this you can use whatever protocol or scheme you want as long as the EMS server and the access NEs can communicate to each other. SORRY FOR NOT HELP YOU IN THIS PART OF YOUR PROBLEM
Also when the Access NEs and the EMS server are on different networks (physically) you need to make static routes to the EMS server and also to the NEs, to the server you can run the command route add of windows (if it is solaris you need to get help from people that know how to do this because I don´t) and to the NEs you can go to the menu Device Management > SDH Management > Static Route Config to configure the static route to the server being the target IP the IP address of the server and the gateway the IP address of the router or switch directly connected to the QX of the NE
If this words do not help you at all, you can request for help formally to our office in Venezuela or maybe the chinese at HQ (the chinese of your country should supply you with the propper documentation)
My skype is amedin4 but I will not be in the office this week I will be on site.
And again please forgive me if with this you cannot solve your problems if it was on me I personally would go there and help you, but you can look for documentation on ECC and Gateway configuration on the support page, the DMS or the gold book, if you don´t know these things please contact you chinese staff they should know them.
