During testing AR18-33 and Metro1000 equipment we met following problem:
Networking: AR18-33 (SHDSL interface) --- Metro1000 (SHDSL interface).
Using such interconnection, SHDSL link always in DOWN state.
On router SHDSL interface we tried several work mode.
We use following board on AR router: QuidwayR3680E,RTJM11SHA,1-Port G.SHDSL(ATM Mode) Interface Module MIM interface, BOM:02312004.
1.We check all the confiuation( Router and M1000) according to the R&D suggestion, but the interconnection can not successful.
2.Relpace the router, still can not solve.
3.So we ask R&D make experient and find the reason:In fact, Metro1000 and AR1833 are designed for different applications, the Metro1000 transports STM (Synchronous transfer mode) stream by inserting STM data into a G.SHDSL frame, the AR1833 transports ATM (Asynchronous transfer mode) data by carrying ATM cells on the G.SDHSL bearer channel. The implementation depends on the hardware, so we can not change the framer type of CO and CPE by setting software. We suggest that using a modem as a converter bridge the metro1000 and router.
4.So in theroy, the router can not interconnection with M1000 SHDSL board, if you want interconnect, it must use Modem connect with router and then the connect with M1000.
