Modem Over IP

2 Ch. or 4 Ch. FXS or FXO over Ethernet (TC3848-3 and -4)

The TC3848-3/4 Modem-over-IP Gateway (MoIP) links or extends up to four channels of 2-wire telephone/dial-up across Layer 2/3 Ethernet, IP or MPLS networks. It is compatible with CCITT and Bell data modem standards. It is easy to configure, offers extremely low latency and supports point-to-point and point-to-multipoint topologies.

Available as a standalone product or JumboSwitch interface card, the TC3848-3/4 is specifically designed to extend dial-up devices like data modems, meters, fax machines and credit card machines over Ethernet/IP connections because VoIP is designed for voice and usually doesn’t support dial-up connections.

The TC3848-3/4 provides Toll Quality sound and supports voice frequencies from 300Hz to 3.4KHz. It achieves minimal end-to-end processing delay (latency) by using high performance buffering and forwarding technology. Analog signals are transported on a 64Kbps channel without compression.

VLAN and QoS for packet prioritization ensure reliable communications. Other key features include Traffic Monitoring and Statistics, Network Time Server (NTP Server), Remote Firmware Upgrade and Temperature and Power Consumption Monitoring. Diagnostics include LED indicators.

The TC3848-3/4 is available in industrial hardened versions (-40°C to +80°C) and exceeds all pertinent industry and environmental standards including IEC 61850-3, IEEE 1613 & NEMA TS-2.

Setup, diagnostics, and management are accessed via Web, SNMP, Serial Console, and Telnet. The TC3848-3/4 fits any JumboSwitch chassis option including 2S Standalone chassis and 1U/2U/4U card cages. Power supply options are 12VDC, 24VDC, -48VDC, 125VDC (available on 1U/2U/4U card cages only) or 115/230VAC.

Applications

The TC3848-3/4 MoIP Gateway is used to link analog telephones or legacy dial-up devices including data modems, fax machines, meters, ATM machines and Credit Card machines over Ethernet/IP or MPLS networks.

It can also be a critical connectivity product for completing migration from a legacy network to a fully integrated voice and data over Ethernet/IP network.

Typical applications include:
  • Connecting a TC3848-3 FXS interface to a 2-wire analog phone station and a TC3848-4 FXO interface to PSTN for outside telephone service
    Phone Link Extender
  • Connecting a TC3848-3 FXS interface to a dial-up meter in the field and a TC3848-4 to a PBX to enable a PC with a built-in dial-up modem to collect information and communicate with a central office.
    Remote Meters on Dial-Up Applications
  • Connecting ATM or Credit Card Machines to a central processing center.
    ATM and Credit Card Machines on Dial-Up
  • Extend Analog Phones or Legacy Dial-up Devices over Ethernet / IP Networks
