Product Overview

PRI ISDN Multiplexer PRI ISDN (Primary Rate Interface) ISDN Multiplexer provides an efficient and cost effective platform to convert 30 dial-up, analog voice circuits to a digital E1, PRI ISDN interface, as per ITU-T Rec. Q.931.

The PRI ISDN (Euro ISDN) Multiplexer may be used to connect fully digital corporate LAN's and ISP equipment and networks with an E1, PRI ISDN interfaces to analog PSTN circuits, or analog equipment. The PRI ISDN Multiplexer bridges the gap between the analog and the digital E1 world, by providing an intelligent interface to inter-connect the Analog to the Digital.

The PRI ISDN (Euro ISDN) Multiplexer is an ideal choice for corporate and ISP customers who wish to connect their equipment with an E1, PRI ISDN digital interface, to either analog equipment or to analog PSTN lines.

The PRI ISDN (Euro ISDN) Multiplexer offers all types of analog interfaces (FXO / FXS / 2W/4W E&M) that may be required to connect to an E1, PRI ISDN digital network. The PRI ISDN Multiplexer shall interface to the E1, PRI ISDN port of any Switch / PBX using PRI ISDN (Euro ISDN) signaling as per ITU-T Rec. Q.931 to inter-connect up to 30, analog interfaces to the E1, PRI ISDN port.

The PRI ISDN (Euro ISDN) Multiplexer is especially useful for providing an analog interface to the latest servers from the following companies:

Cisco AS5300 VoIP servers
Lucent ITS-SP, VoIP server
Ericsson Webswitch, VoIP server

Nuera 200 VoIP servers
Lucent ITS-SP, VoIP server
Lucent PortMaster 3

Usually, the cable plant of most telecom service providers is not designed to deliver E1 services to connect the fully digital corporate LAN and ISP networks, which in such cases can only be accessed by dial-up, 2 wire analog lines - the only available links for connecting the Exchange (Central Office) to the corporate / ISP networks.

PRI ISDN (Euro ISDN) Multiplexer is especially useful in countries where the cable plant is not equipped to deliver E1 or T1 services to the customers, who are using the next generation network access equipment which can only connect to an E1 or a T1 interface.

The PRI ISDN (Euro ISDN) Multiplexer may be used for terminating long distance traffic with PSTN lines that shall support, or, Shall not support "battery reversal/polarity reversal" (answer supervision).

PRI ISDN (Euro ISDN) Multiplexers are available in two versions:
PRI ISDN (Euro ISDN) Multiplexer, can be used with PSTN lines that shall support "battery reversal / polarity reversal" (answer supervision).	PRI ISDN (Euro ISDN) Multiplexer "spoofs" battery reversal / polarity reversal (answer supervision), and can be used with PSTN lines even if they shall not support "battery reversal / polarity reversal" (answer supervision)

Usually, inter-connectivity problems arise if only 2 wire, analog lines are being provided by the telephone company to the subscriber premises to connect the next generation, digital corporate, LAN and ISP networks which can only connect, directly, to an E1 or a T1 interface. Most of the next generation network access servers, available today, can only connect to the PSTN through digital E1 or T1 interfaces.

Installing multiple PRI ISDN (Euro ISDN) Multiplexer systems can provide multiple E1 Interfaces. The equipment supports V.34, download data transmission rates of 33.6Kbps and upload transmission rate of 31.2kbps.
