Leased Line Modems
RayTel Motorola 202T Bell 202T Analog Modem 2-wire Half Duplex or 4-wire Full Duplex for Leased/Private Lines.

The Raymar-Telenetics MOT202T is the original and iconic Motorola 202T modem that has been ruggedized to be industrial grade including hardened for extended temperature operation from -40C to +85C.

• Lease Line Operation - 2-wire half duplex or 4-wire full duplex leased line or private line operation.
• Bell 202T Compliant - 0 to 1200 bps data rate over unconditioned lines and 1800 over high quality lines.
• Anti-Streaming - Anti-streaming feature prevents a modem from remaining in the transmit mode when the modem is not actively transmitting data.
• Robust FSK Modulation - Phase coherent, frequency shift keyed (FSK) modulation provides reliable data transmission on noisy lines delivering solid performance despite interference or limited signal quality.
• Clear LED indicators - The modem has clearly visible LED indicators for RTS, CTS, DCD, RD, TD, TM (Test Mode) and PWR.
• Front Rotary Mode Controls - The modem employs a rotary switch to selects test options including Data Mode, Self-Test, Analog Loopback, Digital Loopback, and Test Pattern Transmit.
• Flexible Power Options - AC Power from 115VAC, 60Hz to 220/240VAC 50 Hz Power. DC Power including 12, 24, 48, 125 VDC.

DESIGNED ENHANCED FOR INDUSTRIAL USE-CASES

The Raymar-Telenetics MOT202T is the original and iconic Motorola 202T modem that has been ruggedized to be industrial grade including hardened for extended temperature operation from -40C to +85C. 

The unit features built-in diagnostics, anti-streaming, and multi-power inputs (110VAC, 220VAC, 12-48VDC or 125VDC).

The modem operates over leased or dedicated, loaded or unloaded lines equal to or better than the ITU

(formerly CCITT) M.1020/1025 or the Bell 3002 leased line services. It operates over point-to-point or multi-point polled systems and operates in full or half-duplex over 4-wire or 2-wire circuits.

SUPERIOR ERROR DETECTION CAPABILITIES

The MOT202T’s anti-streaming capability prevents a modem from remaining in the transmit mode when the modem is not actively transmitting data. In addition, the MOT202T allows users to verify transmitted and received data via the diagnostic feature.

DEPLOYMENT VERSATILITY

The MOT202T’s interchangeable design between the RM16M series universal multiple modem rack and the standalone modem enclosure, enables the modem to be directly rack mounted when the optional front panel is attached. Thus, the data-communications facility can easily upgrade from front multiple standalone enclosures to a centralized rack without the expense and trouble of purchasing new modems.
