PREFACE
PIntroduction
The Mediatrix 1124 provides IP Telephony service to conventional
analogtelephonesorGroup3 faxmachines.Designed for wiringcloset
installation, it leverages existing building telephone wiring to connect
up to 24 extensions to the corporate LAN via a single 10/100 Ethernet
connector.It canbe used eitherto provideconnectivity toan enterprise
IP PBX or to broadband access equipment for a Service Provider's IP
Telephony offering.
To ensure maximum flexibility, the Mediatrix 1124 can:
dynamically detect the most commonly used IP
Telephony codecs and fax protocols, including T.38
be auto-provisioned and remotely managed and
upgraded
provideaconnectiondirectly totheSCN viaanautomatic
Bypass function in the event of an IP network failure or
power outage.
Intended Audience This manual provides all the information needed to installand manage
the Mediatrix 1124. It is intended for network administrators who install
and set up network equipment; consequently, it assumes a basic
workingknowledgeof LANs.Someinstallationproceduresalsorequire
a qualified telephony technician. See“RJ21X Connector” on page 228
for more details.
From the perspective of the LAN administrator, a Mediatrix 1124
presents itself just like another device that is to be added tothe LAN. It
requires the same kind of TCP/IP addressing. The Mediatrix 1124 can
also use a DHCP server on the LAN to automatically receive its IP
configuration assignment.
SCN vs PSTN In Mediatrix Telecom, Inc.’s and other vendor’s documentation, the
terms SCN and PSTN are used. A SCN (Switched Circuit Network) is
a general term to designate a communication network in which any
user may be connected to any other user through the use of message,

details.

circuit, or packet switching and control devices. The Public Switched
Telephone Network (PSTN) or a Private Branch eXchange (PBX) are
examples of SCNs.
