STM-1 Terminal Multiplexer (32 E1 or T1 point-to-point capacity per unit)

CTC Union Part No.: SDH01A-TM

  • $ 1,000.00 or


Product description
SDH01A-TM is an SDH based, STM-1 Fiber Terminal Multiplexer with a total bandwidth capacity of 155Mbps (63E1).

The Terminal Node Multiplexer provides a full Cross-Connect platform for the 63 E1 channels. A modular structure with 4 slots allows up to 32 E1 interfaces to be extracted in a single unit.

Several data interfaces, like Ethernet and synchronous V.35 serial ports are also available to be mapped on the STM-1 channels.

The SDH01A-TM (Terminal Multiplexer) has only one fiber port and can accept a special 8T1 module, so that the SDH01A-TM can be used as a point to point 32 T1 interface fiber multiplexer.

Product Features

  • Up to 32 E1 or T1 per chassis
