OMNIPLEXER

E1/T1 Multiplexer

   The OMNIPlexer is a versatile and cost effective voice/data T1 multiplexer or E1 multiplexer designed to be highly reliable and easy to use. Many of the OMNIPlexer features have been tailored to optimize thin route and polling applications.

• Terminal, drop/insert and branching configurations in a single unit
• Supports point-to-point and point-to-multipoint circuits
• High efficiency sub-rate data transmission, drop/insert individual sub-rate channels
• Unique ability to support virtually all types of telephone exchange signaling protocols
• Long reach capability of the FXS/FXO modules means the telephone can be located several kilometers away from the multiplexer.


 

     FEATURES

• Strict adherence to published industry standards
• Channel bank terminal, drop/insert multiplexer and branching configurations.
• Balanced and unbalanced interfaces for connection to microwave radio and fibre-optic systems
• Interface to copper pairs, using High Bit-Rate Digital Subscriber Line (HDSL) interface enabling E1 transmission over distances to 5 km.
• Fibre optic interface, using an integrated E1 or T1 fibre optic modem for transmission up to 25 km.

 


    MODULES

• 4-wire and 2-wire E&M for voice trunking
• 2-wire loop/ground start (FXO/FXS) supporting subscriber lines and telephone extensions
• Conferenced Omnibus voice for party-line and orderwire channels, featuring integrated DTMF decoding that provides selective call functions
• Low speed data (0-64 Kbps) with built-in sub-rate multiplexing and sub-rate drop/insert for efficient and flexible data transmission
• High speed data (Nx56/64Kbps) for super-rate data transmission, including all intermediate rates
• Point-to-multipoint data for polling and data distribution applications
• 10BaseT ethernet bridge, LAN extensions

 OVERVIEW

  Today's customers require low-cost network solutions that deliver high speed connections to the Internet and Corporate Intranets while supporting videoconferencing and many other wide-area services. The NetLink Model 2707 E1 NTUs satisfies those needs.

  The NTUs terminate G.703 and connect to the customer's router, FRAD, CODEC, and switches with a V.35, X.21, or 10Base-T Ethernet interface.

 


 

ETHERNET VERSION

   Our Ethernet version, the Model 2707/I offers 10Base-T bridging and supports PPP and 802.1q VLAN tagging, passing VLAN-tagged packets of up to 1522 bytes.

  These features enable customers to extend a router's serial interface and connect to a remote 10Base-T Ethernet LAN (see diagram below). The 2707/I uses MAC learning and forwarding to provide seamless LAN-to-LAN connectivity.
