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.

The TE400 Series cards can be used to connect your Asterisk machine to
the PSTN world, your channel bank, or even another PBX. This is
accomplished via a T1/E1 interface. The cards allow Asterisk software to
connect to your network, creating a professional telephony environment.
Figure 2 shows an example of the card’s primary application.

Chapter 1: Overview
Echo-Cancellation
Users connecting their TE400 Series cards to the PSTN or other devices
are likely to be placing calls that will result, at some point, in an
unbalanced 4-wire/2-wire hybrid. The result of this hybrid is the
reflection of a near-end echo to the calling party. Elimination of this echo
is the responsibility of echo cancellation.
The TE400 Series cards, unless otherwise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk maintains a number
of open source echo cancelers. These open source echo cancelers provide
a moderate level of echo cancellation, but are not capable of dealing with
higher levels of, or more advanced, echoes.
Digium recommends that those users concerned about echo cancellation
purchase the VPMOCT128 hardware echo cancellation module. The
VPMOCT128 may be combined with either the TE405P (as TE407P),
TE410P (as TE412P), or TE420 (as TE420B) cards.
The VPMOCT128 is designed to handle up to 128ms of echo cancellation
across all channels and provides a G.168 compliant echo cancellation
solution.
If equipped and not explicitly disabled in chan_dahdi.conf, the
VPMOCT128 will automatically operate and cancel all network echo
within its tail range (1024 taps). Users may also purchase Digium's
commercial HPEC software:
