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.
