FAQ-The manangement of the COA boards which is connected to Metro 1000 through T2000

Publication Date:  2012-07-24 Views:  105 Downloads:  0

Issue Description

We want to use one COA boards to Metro 1000, but because that there's no F&f port on Metro 1000, so we can not connect this COA boards to the equipment.
Then we can not monitor it in T2000.
So, we are trying to find a way to monitor this COA boards as follow:
1. connect this COA board to the serial 1 port on Metro 1000.
2. configure an transparent services between this Metro 1000 and another Metro 3000 equipment to implement that the Serial 1 port can communicate with the
Serial 1 port of Metro 3000.
3. There is another COA board already used by the Metro 3000 equipment which already connected to the F&f port of Metro 3000. There's another port on COA
 board is not used.
4. Then we can use this not used port to connected to the Serial 1 port of Metro 3000, which is configured to communicate with the Metro 1000's serial 1 port.
5. Set the dipswithes of these 2 COA boards, so that we can monitor it all on the T2000
For details, please check the attachment.

Handling Process

We can implement it as below:
1. connect COA board to Metro 1000's "F2" port.
2. create F2 communication between the Metro 3000 and Metro 1000.
3. connect the Metro 3000's COA board's RS232 port 2 to the Metro 3000's Serial 3 ports.
4. Then create COA board on the T2000. 
5. the RND proved that it works.
6 but pay attention to the COA and 2500+ and Metro 1000's serial ports is different definited:
   COA and 2500+: RX / TX / GND = 2/3/5
   Metro 1000:        RX / TX / GND = 6/7/5
R&D has checked this scheme and tested in the lab, it was validated that the scheme is feasible.
Please pay attention to the difference of  the serial port  and make correct connection.
COA and 2500+: RX / TX / GND = 2/3/5
Metro 1000:        RX / TX / GND = 6/7/5
