CC Microcontroller ISDN TA Reference Design Manual
B-3
R -Interface - Reference point between non-ISDN devices and terminal adapters.
SBP - Serial Bus Port. The simple PCM highway used by the Am79C32A device.
SS7 - Signal System 7. High-speed, common channel interoffice signaling system
necessary for ISDN implementation.
S/T-interface - The reference point comprising the 4 wire interface between the
network termination device (NT1) and the terminal equipment (TE1) or terminal
adapter (TA). If an NT2 is used for on-site switching, the S and T reference points
are considered to be separated at the NT2 device. The T reference point is between
the NT1 and NT2, and the S reference point is between the NT2 and the TE1 or TA.
TA - Terminal Adapter. Converts analog information from a TE2 device to digital
format which can be used for ISDN.
TDM - Time Division Multiplexing.
TE - Terminal Equipment. Equipment that may be placed on ISDN (directly or
indirectly).
TE1 - Terminal Equipment Type 1. ISDN compatible terminal equipment.
TE2 - Terminal Equipment Type 2. Non-ISDN compatible terminal equipment,
which requires a terminal adapter.
U-interface - Reference point comprising the two-wire interface between the LE
and NT device.
USB - Universal serial bus. Intel standard; used for PC-to-peripheral
communication.
