2.4.10.2 ARIA-130 ISDN PRIB(Primary Rate Interface Board)
ARIA-130 PRIB (Primary Rate Interface Board) is capable of connecting to 1 PRI line, which has an
interface circuit for 30 time slots with 2.048Mbps data rate speed. PRIB will be positioned at reference
point la on ETS 300 001, that is TE slave without power feeding. And, Data & bit clock are transmitted by
the NT master and extracted by TE salve.
Compared to GDK-100 PRIB, ARIA-130 PRIB doesn’t have on-board processor and is controlled by main
CPU on MPB.
PRIB can be installed in the universal slot No. 1-6 in any KSU.
Max. 2 PRIBs can be installed in ARIA-130 system.
But, ARIA-130 supports up to max 40 B channels with max 2 PRIBs.
2.4.10.3 GDK-100 ISDN BRIB (Basic Rate Interface Board: T interface only)
BRIB has specified to support four interface circuits that allow interfacing the ISDN BRI. Four interface
circuits are used for the transmission of digital signals. Data & clock are transmitted by the NT master and
extracted by TE salve. BRIB will be positioned at reference point Ia (T) on ETS 300 012, that is TE slave
without power feeding.
BRIB contains reset and watchdog circuit, address decoder, external RAM, program memory (ROM), the
circuitry to control the highway interface (DBID), and the board line’s specific circuitry. The board line’s
specific circuitry is PEB2084 for Physical layer and PEB2075 for data link layer.
BRIB can be installed in the universal slot No. 1-6 in any KSU.
The maximum 5 BRIBs can be installed in ARIA-130 system.
2.4.10.4 ARIA-130 ISDN BRIB
BRIB has specified to support two interface circuits that allow interfacing the ISDN BRI. two interface
circuits are used for the transmission of digital signals. Data & clock are transmitted by the NT master and
extracted by TE salve. BRIB will be positioned at reference point Ia (T) on ETS 300 012, that is TE slave
without power feeding.
Compared to GDK-100 BRIB, ARIA-130 BRIB doesn’t have on-board processor and is controlled by main
CPU on MPB.
BRIB can be installed in the universal slot No. 1-6 in any KSU.
The maximum 3 BRIBs can be installed in ARIA-130 system.
2.4.10.5 ARIA-130 ISDN BRIU
BRIU has specified to support two interface circuits that allow interfacing the ISDN BRI. two interface
circuits are used for the transmission of digital signals. Data & clock are transmitted by the NT master and
extracted by TE salve. BRIU will be positioned at reference point Ia (T) on ETS 300 012, that is TE slave
without power feeding.
ARIA-130 BRIU can be installed on the ARIA-130 BRIB optionally.
