Arcatech is one of the UK's most respected telecommunications design and development companies, with numerous prestigious awards for innovation and export achievement. Having earned a reputation for the most extensive range of ISDN BRI and PRI simulators, Arcatech has used this platform to launch the Arcaplex|Horizon ISDN multiplexer series.

arcaplex|Horizon is a simple device for concentrating PRI, BRI and PSTN traffic onto a single PRI line to the central office. Up to 1 PRI, 16 BRI and 32 PSTN connections are possible on the arcaplex|Horizon. Two arcaplex|Horizon units may be daisy chained to give higher levels of concentration. arcaplex|Horizon is a modular device which allows you to select the interface types best suited to your application.

• Mains and -48Vdc versions available

arcaplex|HorizonPrimary to Basic Rate ISDN Multiplexer is a standalone unit that breaks a primary rate ISDN line (E1 or T1) and breaks it into multiple basic rate ISDN lines (S or U), analogue lines, and a sub-equipped primary rate ISDN line.

Each basic rate interface uses two B channels of the primary rate line. Hence an E1 PRI (30 B channels) allows up to 15 BRIs using 2 B channels and a T1 PRI (23 B channels) allows up to 11 BRIs using 2 B channels. Once the BRI channels are enabled the remaining available B channels on the PRI are provided on a downstream sub-equipped PRI for PBX or other use.

The analogue interfaces work independently of the BRIs and a single PRI B channel is used for each analogue interface enabled. The analogue interfaces work like regular Telco lines and provide -48-V feeding, ringing, and CLI functionality.

Each BRI can support up to eight terminals. The data links are handled locally and point-to-point and point-to-multipoint links are selectable. Calls are mapped from the PRI to BRI/analogue interfaces using an MSN numbering scheme.

Basic rate interfaces (BRI) and analogue (POTS) interfaces are provided by line cards. Up to 2 line cards can be fitted to the arcaplex|Horizon. There are 2 BRI line cards - a card with 8 S0 interfaces (I.430 compatible) and a card with 8 U interfaces (ANSI T1.601 compatible). The POTS card has 16 interfaces. The Primary rate interfaces (PRI) can be configured as S2m interfaces (i.e. E.1 G.703 compatible) or T.1 interfaces.
