6.1.2 What You Need to Know About Servers

FXO Channel
An FXO channel is a connection from the X6004 to a traditional PBX (for example a PSTN
connection) via one of the FXO ports installed on the X6004. After you install the FXO
interface card on the X6004 (see the Quick Start Guide), you must configure how the X6004
adjusts the signal volume sent to and received from a traditional PBX.
FXS Channel
An FXS channel is a connection from the X6004 to an analog phone via one of the FXS ports
installed on the X6004. After you install the FXS interface card on the X6004 (see the Quick
Start Guide), you can configure how the X6004 adjusts the signal volume sent to and received
from a connected device such as an analog phone or a PBX.
BRI/PRI
BRI (Basic Rate Interface) and PRI (Primary Rate Interface) are Integrated Services Digital
Network (ISDN) physical layer standard and used to transmit voice and user data. BRI is used
in homes or small companies providing data rates up to 128 kbps. PRI is used in larger
enterprises providing data rates more than 1.5 Mbps.
T1/E1
T1 and E1 are ISDN PRI line types. Both are telecommunication standards widely used in
North America and Japan (T1) or outside of them (E1) to transmit voice and data between
devices. T1 provides up to 1.544 Mbps and E1 provides up to 2.048 Mbps of connectivity.
NT/TE
TE (Terminal Equipment) refers to an ISDN user device such as an ISDN telephone, video
telephone, digital fax machine (also known as G4 fax machine). The NT (Network Terminal)
is the termination device between TEs and ISDN central office (CO). The NT is responsible
for performance, monitoring, power transfer, and multiplexing of the channels. You must
connect a TE device (configured as TE mode) to a NT device (configured as NT mode) to
access an ISDN network.
