Digium’s new TE131, TE132, TE133 and TE134 single span digital cards are the latest additions to the Telephony Card family. The TE13x design utilizes state of the art technologies to support T1/E1/PRI environments that require a high-performance, cost effective digital telephony interface card. The TE13x family of cards have the ability to create a seamless network, interconnecting traditional telephony systems with Voice over IP technologies.
The Main difference between the old and new digium cards is that , the new digium cards wont have E1/T1 jumpers , which can be defined via software and conf files.
The following Blog will instruct you on how to install Digium TE133 and TE134 in you asterisk as T1 or E1
The new digium cards requires latest dahdi and libpri driver min: 2.9 are above version.

Configuring in E1 mode
******************************
Step 1:
Go to : /etc/modprobe.d/dahdi.conf (ie: vi /etc/modprobe.d/dahdi.conf)
And enter below line at last ,save and exit
options wcte13xp default_linemode=e1
Step 2:
Run the below command as root
# modprobe wcte13xp default_linemode=e1
#dahdi_genconf -v
#dahdi_cfg -v (make sure the ouput should show 31 channels)
Note: dahdi_genconf will generate default configs for digium cards, if your pri CRC4 is disabled, then do the changes in /etc/dahdi/system.conf
Step 3
Now open /etc/asterisk/chan_dahdi.conf and add the below line at the last line (use shift+g to go to last line in putty)
#include dahdi-channels.conf
Step 4
Dialplan to dial via PRI
vi /etc/asterisk/extension.conf
[default] ; the default will already exists in most asterisk installation if not create a new
exten => _9X.,1,Dial(DAHDI/g0/${EXTEN:1},30)
exten => _9X.,2,Hangup()
Note: 9 is just a prefix, and it will be discarded while dialling out
Note: for vicidial /goautodial use below dialplan in dialplan entry or extensions.conf
exten => _9X.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _9X.,2,Dial(DAHDI/g0/${EXTEN:1},,Tto)
exten => _9X.,3,Hangup

Troubleshooting PRI issue
******************************
* make sure pri is up by typing below command in asterisk cli
dahdi show status
pri show spans
* enabling or disabling the crc
If the dahdi show status show ok but still pri show spans shows down, try disabling the crc4 from the below conf file
vi /etc/dahdi/system.conf
* if the line is up and still not dialling then do the following changes in chan_dahdi.conf
pridialplan=unknown
prilocaldialplan=unknown
* incomming calls will land in from-pstn context ,
* to change the incomming context go to /etc/asterisk/dahdi-channels.conf and change from-pstn to what ever you want
* for vicidial put trunkinbound as inbound context.
