Hello,
so far I have never been involved with using SHDSL between routers.
I must now test SHDSL routers with a connection between them over a (telephone quality) wire pair.
Before performing a field test, I would like to do an in-house test.
After inserting some basic configuration in the routers (CISCO1841), the status of the WIC-1SHDSL module indicators is the following:
OK : green
LP : no light
CD : no light
How do I connect directly between the SHDSL modules :
Is a straight RJ11 to RJ11 cable sufficient, or is a kind of a cross-cable needed ?
w.r.t. configuration, I found the SHDSL interfaces to be known in the software as "interface atm0/0/0".
For this interface I defined the dsl linerate "auto", the encapsulation as "shdsl symmetric annex A", and the dsl role as "co (central office)" for one of the routers and "dce" for the other router.
In an example I found further configurations about pvc 0/NN as aal5-something, and pvc 0/MM as aal5mux, with reference to a dialer group or pool.
So I copied this part of the configuration (from Cisco document on web regarding "shdsl back-to-back"). This document uses Cisco 825 and 2600 routers, but I suppose the configuration on 1841 is similar.It is the same WIC anyway.
Can anyone confirm (or deny) that such complex configuration, with dialers, dialer pools etc... is necessary for the configuration ?
I would appreciate a configuration example that has proven to be functioning in your network.
So far, I have not yet tested with a DSL cross cable (crossing between pins 3 and 4 on the RJ11 connectors), but that is the next thing on the agenda.
Can anyone confirm (or deny) that for local tests a cross cable is needed ?
Thank you for any help.
