Overview
The Digium TE400 Series cards are a T1/E1 capable card series created
for voice and data. They support industry standard protocols, including
Robbed Bit Signaling (also known as CAS or Channel Associated
Signaling), CCS (Common Channel Signaling), E&M, Primary Rate
ISDN (PRI), and several data modes (PPP, HDLC, Cisco HDLC, and
frame relay). The TE400 Series cards are capable of running in E1, T1, or
J1 modes. They are also capable of DACSing channels from one span to
another. The TE400 Series are ideal for connecting phones to a channel
bank, connecting to your T1/E1 switch, or connecting to a legacy PBX.
This manual is for use with the TE420/TE420B PCI Express card, as well
as the 5 volt TE405P/407P and the 3.3 volt TE410P/412P Quad T1/E1
PCI cards. These cards are identified collectively as the TE400 Series
cards throughout this manual.
Designed to be fully compatible with existing software applications and
integrate fully with the Asterisk platform, the TE400 Series cards allow
many advanced call features.
