[asterisk-r2] E1/R2 on TE121B Digium Card

[Rayan (m0wKz) Pepito]

Hi Alex,

good morning and thanks for your reply.
we talked with our telco and said they will give the details today.
we don't know much about the line and the modem they provide.
they just said that it is an E1/R2 CAT5 cable (RJ45), they also said that it is already up.

will inform you more about the details later.
again, thank you.

Hi Rayan, good morning,

I think you are using a Balun to convert ballanced/unballanced (or you
telco give you a RJ48C interface?). Did you checked if you Balun RX
cable is connected to modem TX and Balun TX connected to modem RX?
                                                RX      Coax       TX
+-------------+        CAT5e
+--------------------------+-------------+  Telco CCI
| Asterisk +[E1]---------------[Balun]                            |
Modem  +----------------|
+-------------+         Cable
+---------------------------+-------------+
                                                TX      Cables     RX

(if gmail blows up thing, copy and past to a text editor)

If this setup is correct, check with your telco provider...
