We have MA5600T MSAN which is connect to Ericsson TSS through Cisco router. MA5600T MSAN have version V800R06C02SPC100, while ericsson TSS have version 4.0.
Customer start with integration Huawei MA560OT MSAN with Ericsson TSS in order to start with big installation of MA5600T MSAN. One of test case was to test old telephons with pulse dialing. When they perform testing we conclude that we can not establish neither the one call.
After I check with customer on TSS it's look that everything is OK. Also we test same service on UA5000 PVMB R17 and everything work fine. So we conclude that problem is on MA5600T MSAN.
After I check oversea parameters 1 and 0 configuration I saw that seting of this two parameters is wrong. Oversea parameters 0 was set with value 300ms and oversea parameters 1 was set on 500ms.
Seting of this paramaters lead to problem that MA5600T MSAN can not recognize when it's somming digits.
After I set oversea parameters 0 to be value 800ms and oversea paramaters 1 to be 100ms problem solve
Possible reason of fault can be:
1. Problem with MA5600T MSAN
2. Problem with old telephons
3. Problem with TSS
