Hi there,

we are setting up a Elastix with a Digium TE200 card.
The system is in a data center, we manage it remotly.

Problem is that we think that the jumper is on T1 mode because:
- we see 24 channels + 24 channels in hardware detection.
- all the modification to the system.conf working with 1-15, 16-31 failed

Are there any way to know if the card is on T1 or E1 mode?.

Thanks !!!!

Thanks Fernando !!!!

Does the software solution works to change the type from T1 to E1?

3.1.2 Software solution

The second solution is to override the jumper settings. Two ways : linux command modprobe + parameter or small software hack ;)

modprobe
In case you have no access to the server you could still override the setting with a parameter to modprobe.
The driver accepts parameter t1e1override and decimal value between 0 and 15 wich corespond to binary from 0000 to 1111 where each bit corespond to a span. 0 is T1 and 1 is E1.

Decimal | Binary
0 | 0000
1 | 0001
2 | 0010
3 | 0011
4 | 0100
5 | 0101
6 | 0110
7 | 0111
8 | 1000
9 | 1001
10 | 1010
11 | 1011
12 | 1100
13 | 1101
14 | 1110
15 | 1111


But how to know which port is configured for T1 or E1? Take a look at the picture below.

Binary 0 0 0 0
Spans 4 3 2 1



To load a driver with all spans set to E1 do:
modprobe wct4xxp t1e1override=15

There is also a debug parameter. To enable debuging via syslog do:
modprobe wct4xxp debug=1

Hack
If the modprobe solution is not working, then edit wct4xxp.c and change 'static int t1e1override = -1;' to 'static int t1e1override = 15;'
