Product Overview

E3, 34Mbps Multiplexer is a third order skip multiplexer / demultiplexer unit, based on PDH (Plesiochronous Digital Hierarchy) technology. It multiplexes sixteen 2.048Mbps (hereafter referred to as 2Mbps) E1 tributaries into a single 34.368Mbps (hereafter referred to as 34Mbps) E3 tributary. The multiplexer / demultiplexer also does the reverse processing i.e. demultiplexing a received 34Mbps stream into sixteen 2Mbps E1 tributaries.

Available with TCP-IP option for remote access through TCP-IP remote access and monitoring solution

E3, 2/34 Mbps Multiplexer system consists of two E3, 2/34 Mbps terminals one each at the local and remote ends, connected through a 34Mbps stream, providing end to end services for sixteen, 2Mbps streams. Both local and remote terminals can be monitored and controlled by a Network Management System (NMS) connected to the local terminal.

The E3, 2/34 MBit/Sec. Digital PDH Multiplexer provides 16, 2Mbps E1 electrical interfaces which are multiplexed to 1, ITU-T compliant E3, 34MBits/Sec. G.703 electrical interface.

Features	Highlights
Single - card implementation Plug and Play Multiplexer Modular 2Mbps transmission units Standard CCITT (ITU-T) compliant interfaces Capable of synchronizing on any of the 34368 kHz clock sources - internal, external or extracted Remote and local terminal monitoring and control by Network Management System Optional TCP/IP Remote Access for monitoring alarms and management	Extensive alarms and status indication facility Service bit monitoring and insertion Operates on nominal -48V DC input Distributed on-board power supply Microprocessor controlled with powerful diagnostic facilities for both remote and local systems Local and remote loopback facility for 34Mbps stream Stored program controlled Highly reliable and compact

The system may be deployed independently (with an industry standard OLTE) or in conjunction with Optical Line Terminating Equipment (OLTE) in the following applications:

To provide inter-connectivity between two small switches (central offices).
To provide connectivity between the Central Office and the Remote Site in "Fiber In The Local Loop" application.
To connect ISP's (Internet Service Providers) to the "telco".
To provide an intermediate connecting link at 34MBits/Sec. in mixed PDH/SDH networks.

External Interfaces:

E3 unit provides the following interfaces to the external world:

16, primary rate, 2Mbps, 120 ohm balanced interface
1, third order, 34Mbps, 75 ohm unbalanced interface
-48V input for E3, 2/34 on-board power supply
RS232 interface for connection to Network Management System, used for configuration and monitoring of the E3, 2/34 multiplexer.
2 alarm extensions for visual and audible alarms.

PROGRAMMING AND MONITORING

E3, 2/34 Mbps Multiplexer offers programming via an RS232 port for control and monitoring of the terminals. Both local and remote multiplexer can be monitored and controlled using a PC loaded with the NMS software connected to the local terminal.

Programming Features	Status Monitoring
Setting master / slave identity for each E3, 2/34Mbps Multiplexer system Setting local / remote identity for each E3, 2/34Mbps Multiplexer system Specifying the priority sequence for clock selection. Setting local or remote loopbacks on 2Mbps or 34Mbps Enabling or disabling 2Mbps channels Initiating self tests Alarm acknowledgment option	Presence or absence of remote terminal Priority sequence of clock selection and current clock on which the system is working Status of alarm Presence or absence of loop-back on 34Mbps and 2Mbps streams Enabled / disabled status of 2Mbps channels Master / Slave status Monitoring healthy / unhealthy state of microcontroller and 2Mbps line interface units
