Features of ISDN:
1) Uses Digital Signal
2) Uses Existing telephone wiring
3) Charges are generally based on the duration of call (How)
long the WAN link was used)
4) Alternate to using leased lines
5) Can transport many types of Network traffic (Voice, Data,
Video, Text, Graphics etc)
6) Faster Data transfer rate than modems
7) Faster Call setup than Modems
ISDN Components:
Terminal Equipment type 1 (TE1)
*ISDN compatible device (Router with ISDN Interface)
*TE1s connect to the ISDN network through a four-wire,
twisted-pair digital link
Terminal Equipment type 2 (TE2)
*ISDN Non-compatible devices.
*Will require a terminal adapter.
Terminal Adapter (TA)
*Converts standard electrical signals into the form
used by ISDN
*Needed for connection with TE2 devices
*The ISDN TA can be either a standalone device or a
board inside the TE2
Network termination type 1 (NT1)
*Network-termination devices that connect the four-
wire Subscriber wiring to the conventional two-wire local
loop
*Is a customer premises equipment (CPE) device
(North America)
Network termination type 2 (NT2)
*Intelligent device that performs switching &
concentrating.
*Provides multiple ISDN interfaces on an ISDN line.
The NT2 may be as simple as a bridging device
connected to an NT1 unit or it may be as complicated
as a PBX (Private Branch exchanges)
