Chapter 1
Overview
The Digium TE130 Series cards are a T1/E1 capable card series created
for voice. They support industry standard protocols, including Robbed Bit
Signaling (also known as CAS or Channel Associated Signaling), CCS
(Common Channel Signaling), E&M, and Primary Rate ISDN (PRI). The
TE130 Series cards are capable of running in E1, T1, or J1 modes. The
TE133 and TE134 models include onboard DSPbased G.168complaint
echo cancellation. The TE131 and TE132 models rely on softwarebased
echo cancellation and (unlike many other Digium card products) cannot
be upgraded with any modular echo cancellation.
Designed to be fully compatible with existing software applications and
integrate fully with the Asterisk platform, the TE130 Series cards allow
many advanced call features.
