PRI to BRI Multiplexer

Talk to us about this

Description

Arcaplex Horizon is a simple device for concentrating PRI, BRI and PSTN traffic onto a single PRI line to the central office.

Arcaplex Horizon is a modular device which allows you to select the interface types best suited to your application.

Reduce your network costs, why rent many expensive BRI lines when a single Primary rate ISDN (PRI) line offers lower rental and installation costs per channel. In most countries it is possible to have a part-enabled PRI interface which will only incur rental charges for the number of channels required.

Why start adding more BRI lines to your network when a PRI or part-enabled PRI line will give you additional growth potential with lower cost per channel than adding more costly BRI lines.

Key Features

Arcaplex Horizon Primary to Basic Rate ISDN Multiplexer is a standalone unit that breaks a primary rate ISDN line (E1 or T1) and 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.

Arcaplex Horizon is configured using a V24 interface connection to a PC. Using this connection all of the functions are controlled. Alternatively, the unit can be accessed via Telnet across a LAN or WAN using the built in ethernet port. An internal modem option is also available for management.

Converting PRI to BRI or ANALOG

Video conferencing equipment frequently requires BRI lines for operation. In many cases with the only communications available in a large building being PRI lines the Arcaplex Horizon offers the opportunity to ‘tap off’ some BRI lines from a PRI line coming into a building for use in this type of equipment and allow the remainder of the channels to be fed out again to a PBX upstream.

Likewise if there is a requirment to have analog lines available it is possible to convert - split these out when only a PRI line is available.
