Q: Can I use TN55TTX on General OSN8800 T32 subrack?

A: No, TN55TTX only can be applied to Enhanced 8800 T64, Enhanced 8800 T32 and 8800 T16 Subrack.


Q: Why TN55TTX still cannot work on my enhanced OSN8800 T32?

A: Please check your the cross-connect board type plugged into your device:

1, For enhanced OSN 8800 T64 subrack, TTX must work with cross-connect board TNK2USXH+TNK2UXCT.

2, For enhanced OSN 8800 T32 subrack, TTX must work with the TN52UXCH or TN52UXCM.

3, For OSN 8800 T16 subrack, TTX must work with the TN16UXCM.


Q: What is the initial version that OSN8800 can support TN55TTX?

A: It is V100R009C00SPC100, or later version can support.


Q: Why my U2000 NMS cannot recognize TT55TTX?

A: U2000 NMS and OSN8800 device software version need match with each other. Maybe your U2000 version is old.

  1. Algeria
    Get to know Thunder-link via a friend, a reliable partner, we received TTX very fast with test report.
  2. Cape Verde
    We have two TTX, one is TN54 version ordered from Huawei long time ago; the other is TN55 from you. Do they have difference from port mapping function, why we cannot configure MAC transparent mapping successfully on the port of TN54TTX?
  3. Angola
    100% supplied a TN55TTX for me, it used on OptiX OSN 8800 T32 subrack, is there any requirement for cross-connect board?
