The TM2 fiber optic multiplexer is designed to transmit up to two (2) T1 (DSX-1) or two (2) E1 (G.703) or two (2) V.35 Nx64 circuits via one single mode fiber optic cable. With an embedded micro-controller, each channel of the TM2 can easily be configured and monitored through the Network Management Software (NMS). Configuration control includes LBO Settings, Line Code Selection, and AIS Enabling.

The standalone TM2 front panel provides LED status indicators, including local and remote alarms, audio disable push button controls, and NMS ports. The rear panel provides AC/DC power input, E1/T1 or V.35 Nx64 channel modules, fiber optic connection, and relay contacts.

The rack mount TM2 module is a 3 RU plug-in card of the VK2300 chassis system. The VK2300 chassis system can accommodate up to ten (10) TM2 modules, up to two (2) AC/DC power supply modules and one (1)NMS module. The NMS module provides PC connection via RS-232 interface, SNMP interface via 10Base Ethernet connection (option) and DELMONS test ability (option). The front panel provides power and link LED indicators, E1/T1 connections and fiber optic connection.

The management port provides complete system function access with a graphical user interface menu for channel configuration, test, alarm reporting, and status display. System performance monitoring including code violation per each individual data channel, and the system optical composite signal. In addition, the TM2 ‘s internal memory provides and updates historical data performance for every 15 minutes, 24 hours and 7 days intervals.

The TM2 is ideal for implementing simple trunking systems for premise, metropolitan, and industrial environments. Applications for the TM2 include PCS trunking, SCADA, ITS, railway networks, electrical utility networks, and cellular networks.
