Our Role in TDM over Ethernet/IP
Time Division Multiplexing (TDM) over IP is the optimal transition from analog and legacy devices to an IP/Ethernet network. By acting as a pseudowire, TDM over IP technology allows legacy interfaces to maintain critical performance requirements while taking advantage of the flexibility of a packet-based network.
TC Communications specializes in these interfaces including serial data RS-232/RS-422/RS-485, 600ohm Analog Radio, Dry Contact, T1/E1, T3/E3 and data modems.
Many industrial and critical applications rely on minimal latency and high availability standards to operate properly. Here are popular applications.
Specializations and Applications
Serial over IP
Transporting serial data is one of our most common requests. Serial over IP on the JumboSwitch is most commonly used in SCADA, Traffic Control, Rail Signaling, and Teleprotection applications.
Individuals or multiple users can access serial devices such as IEDs and older RTUs.

SCADA Telnet Application
600 ohm Analog over IP
Most often used in Radio over IP solutions, 2 and 4-wire Analog over IP provide stable, high quality voice audio, and maximum system reliability in critical network connectivity applications. TC Communications specializes in (maintaining? keeping up?) reliable networks for critical communications including Public Safety and other emergency networks for Utilities, Rail and Oil.

Modem over IP
Modem over IP 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.

A History of Helping
Multi-County Public Safety Agency Upgrades Microwave Radio Network
A public safety communications network in Iowa required a system-wide replacement to keep police, fire and emergency first-responders connected. Reliability of equipment had degraded and vendor support uncertain. Using a multi-service Ethernet platform (MSEP), STARCOMM was able to improve audio quality and network management. After searching for a compatible option, they decided on the JumboSwitch. With it they were able to enjoy Ethernet port limiting, management and self-healing redundancy.

ESRN Eliminates Leased Line Costs
East Shore Radio Network (ESRN) needed a replacement solution to eliminate their leased line costs. Support for leased lines had also lessened in recent years. Finding a cost-effective and future proof solution was critical. ESRN was able to fully integrate existing equipment while improving audio quality.

Paraguay Power Company Deploys JumboSwitch
South American Power Utilities have traditionally used SDH/SONET systems for their substation communications networks.
However, when the National Power Company of Paraguay (ANDE) received a budget-busting six-figure price quote for each SDH/SONET node for a proposed substation network expansion and upgrade, they immediately began researching lower cost Ethernet/IP alternatives.
