2.4.10.6 ISDN STIB (Basic Rate Interface Board: switch-able S/T interface)
The S or T interfaces are based on the existing interface described in ETSI 300 012, which is based on
ITU_T Recommendations I.430 and provides modification and further requirements.
This is applied at the S or T reference points for the basic interface structure defined in ITU_T I.412.
Layer 1 of the interface requires a balanced metallic transmission medium, for each direction of
transmission capable of supporting 192Kbps(2B+D). Data & bit clock are transmitted by the NT master
and extracted by TE slave. ARIA-130 can be positioned at reference point Ia (T) or Ib (S) on ETS 300 012
that is TE-slave without power feeding or NT-master with power feeding. By selecting the jumper position
on each line interface, STIB supports S-interface (Line card function) or T-interface (Trunk function).
For physical layer interface function, SIEMENS’s PEB2084, Quadruple Transceiver for S/T interface
which implements four wire S/T interface used to link voice/data digital transmission to ISDN BRI is
applied. It can handle up to 4 S/T interfaces simultaneously according to ITU-T I.430, ETSI 300.012, and
ANSI T1.605 standards.
For data link layer interface function, SIEMENS’s PEB2075 ISDN D-channel exchange controller, which is
a serial HDLC data communication circuit with four independent channels is used. Each channel is fully
independent and programmable by its own register set.
For power feeding control, PEB2025(Power feeding device from SIEMENS) is occupied. It can handle up
to 4 channels with current limiting and short circuit protection.
STIB can be installed in the universal slot of slot No. 1-6 in any KSU.
The maximum 5 STIBs can be installed in ARIA-130 system.
2.4.11 VOIB (Voice Over Internet Protocol Interface Board)
This board for the ARIA-130 Digital Key Telephone systems provides VoIP(Voice over Internet Protocol)
feature, which allows Toll-Free communication between two systems via LAN(local area network) that
supports Internet Protocol (IP).
The board transmits and receives voice and data in an IP format to and from the network.
This board supports Voice over IP (VoIP) and Fax over IP (FoIP).
The purpose of the board is to take advantage of the applications offered utilizing IP protocol while
retaining the reliability of traditional telephone PBX. It requires a unique address, known as an IP or
TCP/IP address.
This address must be compliant with IANA (Internet Assigned Number Authority) standards for IP
addressing to insure its individuality. Until the IP address is entered in programming, the VOIB is inactive.
VOIB board complies VoIP Protocol Stack standard, H.323 Revision 2, and in case of connecting to a
system from other vendor, it is strongly recommended to check interoperability before installation and
purchase decision.
To avoid the interoperability problem with other system, it is recommended to use between ARIA-130 and
ARIA-130 or ARIA-130 and ARIA-300.
