Overview ABB extends its comprehensive portfolio of Utility Multiplexers by FOX505, a compact Access-Mux with transport capacity up to STM-1. The network element fully supports ring and linear topologies and is ideal to feed higher order SDH-backbones. Its extended operational temperature range and a wide choice of interfaces match the requirements of most utilities. The 19” wide / 4 units high chassis provides 14 front-access slots for: ■ 2 redundant controller modules ■ 2 redundant, hot swappable power supply modules ■ 2 high speed modules (e.g. STM-1) ■ 8 slots for any combination of other interface cards (e.g. E1, voice, LAN, legacy, G.HSDL etc.) The controller boards provide management access (LAN & RS232) as well as external alarm inputs (3) and one output. In addition, a synchronization port is available. Two board options with different cross-connect sizes allow optimizing this rugged network element technically as well as cost-wise. The design of the multiplexer allows continuous operation at temperatures up to 55°C. Whatever supply voltage in the range of 93-250 VAC / 36-72 VDC is applied, it can be handled by the same type of power supply module and redundant load-sharing operation is fully supported. The device can cope with the typical Ethernet / LAN utility requirements in the field of access-services. An Ethernet switch board offers L1 & L2 functionality whereas the IP / PPP board handles all TDM traffic carrying PPP-encapsulated IP-traffic. Like all other FOX-devices, FOX505 is managed by ABB’s network management system.
