Description
ARG 1900 1945-EQTW1-BOM T3/DS3 ASI Media Combiner Transmitter Dual 44.736Mb/s
The ARG 1900 is a 1U rackmount T3/DS3 media combiner and transmitter designed for broadcast and telecom distribution applications. It accepts up to eight ASI (Asynchronous Serial Interface) copper inputs and combines them for output over dual T3/DS3 telecom ports at 44.736 Mb/s using B3ZS encoding in both framed and unframed modes. This unit is equipped with the web option, enabling remote monitoring and configuration via a 10 Base-T Ethernet connection.

Applications
The ARG 1900 series was designed for professional broadcast and satellite uplink environments where multiple ASI transport streams must be combined and transmitted over a T3/DS3 telecom infrastructure. It was commonly used in broadcast headend facilities, cable and satellite distribution centers, and telecom carrier installations requiring multiplexed MPEG transport stream delivery at DS3 rates. The dual T3 output with B3ZS framing makes it compatible with standard North American DS3 telecom interfaces, while the integrated web management option enabled remote supervision in distributed plant environments. This type of equipment is typically sought by broadcast engineers, systems integrators, and technicians working with legacy ASI/T3 distribution infrastructure.
This ARG 1900 T3/DS3 ASI Media Combiner Transmitter (factory code 1945-EQTW1-BOM) is being sold as-is for parts or repair. The unit appears to power on, but the LCD display is faulty and does not function correctly. Because of this known fault, the unit is listed as-is with no functionality guarantee. Cosmetically, the top cover shows significant discoloration and residue staining as visible in the photos; the rear BNC connectors, RJ-45, DB9, and dual IEC power ports appear physically intact. The unit is not guaranteed functional and is intended for buyers seeking a parts source, a repair project, or component harvesting. Please view our photo set and contact us if you have any questions.
