Telephony Multiplexers

(Showing headlines 1 - 12)   

Multiplexer Appliance supports OC-3 and STM-1 standards.

Sangoma Technologies Corp.    Markham, ON L3R 9R6  Canada
Sep 05, 2012 Providing up to 84 T1 spans or 63 E1 spans, Model STM1-Mux offers capacity to connect 2,016 simultaneous calls. Unit supports direct cable connection with A116 high density digital telephony board, eliminating cross-connect wiring for each group of 16 E1/T1 spans terminated in high-density deployments. Combined with other Sangoma solutions supporting SS7 and SIP signaling and multiple transmissions standards, STM1-Mux can form complete platform to support many business applications.

Inverse Multiplexer uses TDM lines for networks.

Patton Electronics Co.    Gaithersburg, MD 20879
Aug 24, 2007 Featuring dual Gigabit Ethernet ports that support jumbo frames, IPLink(TM) Model 2888 bonds up to 4 T1/E1s for protocol-transparent channel up to 8 Mbps. Unit leverages existing TDM circuits to seamlessly interconnect MPLS/VPLS next-generation networks, while avoiding security issues associated with MPLS. It also transparently backhauls broadband traffic from remote POPs and network peering points, and delivers high-speed network access for bandwidth-hungry subscriber applications.

T1/E1 Extenders triple reach of of TDM circuits.

Patton Electronics Co.    Gaithersburg, MD 20879
Feb 05, 2007 Designed for plug-and-play, back-to-back operation, CopperLink(TM) Models 2113 and 2115 can connect remote PBXs over existing dry copper. They operate in clear-channel mode to transparently extend data and voice bearing circuits. Service providers can extend T1/E1 TDM circuits without repeaters to more than 3.5 miles over single twisted pair. Model 2115 T1 extender comes with RJ-48C connector, while Model 2113 E1 extender includes dual BNC and RJ-48C connectors.

Multiplexer works over STM-1/OC-3 telecom circuits.

A.R.G ElectroDesign Ltd.    Gloucestershire GL7 1RT  United Kingdom
May 08, 2006 Operating at 155.52 Mbps, 1915 Media Combiner allows up to 8 different tributary signals (MPEG, data, or G.703) to be combined into single interface for transparent transport. Available tributary cards include dual DVB/ASI, dual LVDS(SPI), and dual T1/E1 telephony interfaces; up to 4 tributary cards can be installed. Along with variable-rate multiplexing, features include menu-based front panel display, optional internal web server, and dual-redundant internal power supplies.

Multiplexer solves clock recovery and synch problems.

MemoryLink, Corp.    Neenah, WI 54957
May 08, 2006 Supporting 1-8 T1/E1 connections per link, Flanger Backhaul(TM) units enable point-to-point multiplexing of T1/E1 traffic across wired and wireless Ethernet devices. They provide last mile T1/E1 transport across distances limited only by capabilities of selected radio and can also connect PBX systems in remote office environments. Units also allow multiplexing of LAN traffic along with T1/E1 payload, where LAN traffic utilizes available bandwidth in connection.

T1/E1 LIU/Framer suits optical transport applications.

Exar    Fremont, CA 94538
Oct 25, 2005 Voyager XRT86SH328 integrates 28-channel T1/E1 LIU/framer with VT/VU Mapper/DeMapper and M13 multiplexer. Each LIU channel supports R3 Technology, making unit reconfigurable, with integrated termination supporting all T1/E1/J1 line impedances. Architecture supports SONET/SDH compliant T1/E1 de-synchronizers in drop direction in addition to jitter attenuator functionality in add direction. Unit can mix T1s or E1s on any of LIU interfaces without requiring additional timing devices.

Multiplexers enable upgrade to next generation services.

Adtran Inc.    Huntsville, AL 35806 2807
Jun 27, 2005 Model MX3112 enables Ethernet migration from traditional TDM voice circuits to EVDO or HSDPA data services. Drop-and-insert Model MX3208/3216 permits single DS3 to be shared among multiple cell sites. Available in 8 and 16 drop port DS1 models, unit features bandwidth managed IP/Ethernet and terminal server ports. Model MX410 allows DS1 to be cross-connected into separate fractional T1 facilities supporting multiple radios or management filters.

Integrated Access Devices help carriers migrate to VoIP.

Adtran Inc.    Huntsville, AL 35806 2807
Jun 27, 2005 SIP-based Total Access 900 Series allows Incumbent Local Exchange Carriers and Competitive Local Exchange Carriers to implement IP network architecture for VoIP deployment, while supporting customers’ legacy equipment. Units are suited for hosted PBX or IP Centrex applications, and can be used as SIP gateway to overlay additional services to customers. Supporting up to 24 analog voice connections, devices offer T1 port for WAN connectivity, 10/100Base-T Ethernet port, and DSX-1 port.

Multiplexer Chassis provides up to 12 slots.

Multiplexer Chassis provides up to 12 slots.

Beijing Fibridge    Beijing,   China
Apr 19, 2005 Model E1 PDH can combine up to 16 E1 and 4-port Ethernet signals in one fiber channel. With 6U height and up to 24 optical channels, unit is suitable for low capacity, point-to-point remote transmission applications. It includes 48 Vdc power supply, complete alarm functions, one RS232 asynchronous interface, and remote loop back functions.

Media Converter can be remotely managed.

Transition Networks, Inc    Minneapolis, MN 55344
Jan 27, 2005 Suited for point-to-point implementations, Transport MUX can transport multiple T1/E1 lines, 10/100 Ethernet, and RS232 Data Channel over single pair of fiber or single fiber strand. It provides copper connections compatible with G.703, AMI/B8ZS/HDB3, 10/100BASE-TX, as well as RS232 channel; while optical channel will run at 155 Mbps. If fault condition occurs, Automatic Link Restoration ensures that no user intervention is required to bring link back up again.

T1/E1 Multiplexer supports distances to 20 km.

Metrobility Optical Systems Inc.    Merrimack, NH 03054
Mar 09, 2004 Combining T1/E1 single-strand, bi-directional wavelength (BWDM) multiplexer with Ethernet BWDM allows TDM voice and high-speed data traffic to co-exist on fiber pair, without intermixing traffic types. Where fiber is installed between buildings, system can eliminate point-to-point T1 or E1 lines for each location by creating single, private, voice/data network. Optical transmission is immune to EMI emissions.

Access Platform enables economical TDM/Ethernet services.

Larscom, Inc.    Milpitas, CA 95035
May 29, 2003 Plug-and-play Orion 7400 SONET access platform enables carriers to deliver flexible, incremental-level Ethernet-based bandwidth services as well as TDM services on mass-market basis. Product leverages Generic Framing Procedure (GFP)-based Ethernet over SONET (EoS) standards, including Low- (VT 1.5) and High- (STS-1) order Virtual Concatenation. Interoperable with existing SONET infrastructure, it includes up to 16 Fast Ethernet ports in single 1.75 in. high device.
