2. PASOLINK NEO/a is a smart, new solution for the evolving market toward triple play and all-IP
networks in all segments.
Its advanced design provides reliable digital access links that fully exploit the potential of
end-to-end advanced networks. The system meets increasing demand for digital transmission
services satisfying the needs for common carrier access links, private links, urban area networks,
rural area networks, temporary networks or emergency links for voice and data transmissions.
The field-proven PASOLINK equipment offers very high performance reliability, high system
flexibility, and easy installation.
The PASOLINK NEO/a system provides several interface types of PDH, SDH and LAN with
transmission signal of 5 to 48 x E1, 63 x E1, STM-1, 10/100 Base-T and GbE per rack.
Resembling the PASOLINK series, this system consists of antennas, outdoor unit (ODU) and
indoor unit (IDU). Each radio channel is connected through a coaxial cable.
Available configurations are non-protected type (1+0), protected type (1+1) and one- to six-way
Digital Cross Connect. The protected type is available as twin-path type or hot-standby type.
