Product Overview

E1 WAN Access E1-WAN Access Multiplexer provides an efficient and cost-effective platform to convert 30, dial-up, analog voice circuits to a digital E1 interface. E1, WAN Access Multiplexer may be used to connect fully digital Corporate LANs and ISP Equipment and Networks with E1 interfaces to analog PSTN circuits, or analog equipment. The E1, WAN Access Multiplexer bridges the gap between the analog and the digital E1 world by providing an intelligent interface to interconnect the Analog and the Digital.

E1, WAN Access Multiplexer is an ideal choice for Corporate and ISP customers who wish to connect their equipment with E1 digital interfaces to either analog equipment, or to analog PSTN lines. The E1, WAN Access Multiplexer offers all types of analog interfaces (FXO / FXS / 2W/4W E&M) that may be required to connect to E1 digital networks.

E1, WAN Access Multiplexer shall interface to the E1 port of any Switch / Server / PBX using Channel Associated Signaling (CAS, R2 digital signaling) as per ITU-T Rec. Q.421 / Q.422, to interconnect up to 30, analog interfaces to the E1 port.

E1, WAN ACCESS , E1 Network Access Multiplexer is especially useful for providing an analog interface to the latest servers from the following companies:

Cisco AS5300 VoIP servers
Quintum VoIP servers
Patton VoIP servers

Nuera 200 VoIP servers
Lucent ITS-SP, VoIP servers
Mockingbird VoIP servers

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.

E1 multiplexer application, E1, WAN ACCESS, E1 Network Access 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.

E1, WAN Access 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).

E1 channel banks are available in two versions:

E1, Voice & Data Multiplexer, can be used with PSTN lines that shall support "battery reversal / polarity reversal" (answer supervision).
E1, Voice & Data 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 E1, WAN ACCESS systems can provide multiple E1 Interfaces. The E1, WAN ACCESS supports V.34, download data transmission rates of 33.6Kbps and upload transmission rate of 31.2kbps.
