Chapter 1 Overview
Chapter 1: Overview
The 2400 Series cards are versatile devices used for connecting your
phone network to the PSTN (Publi c Swit ched Tele phone Networ k) world.
This is accompli shed through phone lin es connected to the FXO (Foreign
Exchange Office) po rts and phones connected via the FXS (Foreign
Exchange Station) ports. The cards allow Asterisk to connect to your
phone network, creating an office type telephony environment.
There are a variety o f applications where the 2400 Series cards can prove
useful. Some examples are provided in the following figures.

located inside of the same building to mi nimize lightning exposure.

Echo-Cancellation
Chapter 1: Overview
Users connecting the ir 2400 Serie s cards to t he PSTN or other devices ar e
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 nearend echo to the calling party. Elimination of this ech o is the responsibility
of echo cancellation.
The 2400 Series cards, unless other wise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk mainta ins a number
of open source echo c ancelers. These open sou rce echo cancelers provide
a moderate level of echo cancellation, but are not capabl e of dealing with
higher levels of, or more advanced, echoes.
Digium recommends that those users concerned about echo cancellation
purchase the VPMOCT032 hardware echo cancellation module. The
VPMOCT032 may be combined with both the TDM2400P and
AEX2400.
The VPMOCT032 is designed t o handle up to 128ms of echo ca ncell ation
across all channels and provides a G.168 echo cancellation solution.

Chapter 1: Overview
What is Asterisk®?
Asterisk is th e world’ s leading open source telephony engine and tool kit.
Offering fle xibility unheard of in the world of proprietary

for download free of charge. Asterisk is the most popular open source
software avai lable, with the Asterisk Community being the top influencer
in VoIP.
Asterisk as a Switch (PBX)
Asterisk can be configured as th e core of an IP or hybrid PBX, switching
calls, managing routes, enabling features, and connecting callers with the
outside world over IP, analog (POTS), and digital (T1/E1) connections.
Asterisk runs on a wide variety of opera ting systems including Linux,
Mac OS X, OpenBSD, FreeBSD, and Sun Solaris. It provides all of the
features you would exp ect from a PBX inclu ding many advanced f eatu res
that are often associate d with high end (and high cost) proprietary PBXs.
Asterisk's archi tecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-base d telephony equipment using relatively inexpensive
hardware.
Asterisk as a Gateway
It can also be built out as the heart of a media gateway, bridging the
legacy PSTN to the expanding world of IP telephony. Asterisk’s modular
architecture a llows it to co nvert betwee n a wide ran ge of communicat ions
protocols and media codecs.
Digium, Inc. Page 18
Chapter 1: Overview
Asterisk as a Feature/Media Server
