The 2Mbps E1, Drop-Insert (Add-Drop) Multiplexer provides full range of POTS (voice) and digital data services to subscribers located at different locations, requiring to interconnect and establish a voice and data network over an E1 link.

The E1, Voice & Data multiplexer is a simple, and yet a powerful channel bank for connecting and integrating analog communication equipment with digital E1 services.

E1, Drop-Insert Multiplexer provides voice telephony and digital data services which include:

• Voice Telephony (FXO, FXS, E&M).
• Data Communication (V.35, V.24, 64Kbps Co-directional)
• Wireless (Cellular, Microwave Radio) Communication
• Interconnecting computer terminals.
• Interconnecting LAN (Local Area Networks).
• Providing leased data lines and real-time video links to subscribers at speeds ranging from 64Kbps up to 1.024Mbps, using the "N"x64, V.35 data interface card.

E1 Interface operates at a primary rate of 2.048 MBits/Sec and provides a host of features including, channel drop and insert facility, high-speed data ports for digital communication links - including internet access, wide area networking, over a network of E1 multiplexers, for voice and data applications. The E1, Drop-Insert Multiplexer has an effective, Windows based "Network Management System", which may be used for configuring the system and subsequent remote monitoring, management and control of the inter-connected systems in the network. An extensive set of alarms, for easy maintenance are provided in the system. The system supports low speed synchronous / asynchronous V.24 interface and high speed synchronous V.35, G.703 data interfaces. The equipment also supports FXO, FXS and inter-exchange E&M interface used for inter-connecting telephone exchanges ("junction mux application").

E1, Drop-Insert Multiplexer offers an excellent flexibility on the choice of transmission medium over which it may be deployed. The transmission medium may be either twisted copper cable pairs, optical fiber cable, or wireless.

Highlights

• Field upgrade possible to provide voice, data or both services.
• Flexibility on use of transmission medium - copper, fiber, or wireless.
• Choice of Interfaces for Data Applications.
• RS-232, PC Interface "Network Control And Management Software".
• Channel assignment independent of slot position in the subrack.
• Extensive set of alarms.
• Synchronization to different user selectable clock sources (User Selectable Priority Assignment).
