STM-1 Add-Drop Multiplexer (32 E1 or T1 add/drop capacity per unit)
SDH01A-ADM is an SDH based, STM-1 Fiber Add-Drop Multiplexer with a total bandwidth capacity of 155Mbps (63E1).
The Add-Drop Fiber 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 Add-Drop version has two fiber links for ring integration.
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.
