Modules

Chassis

SpiderMUX chassis provides bus communication and synchronization for the rest of modules. It is in 1U form factor that fits all 19" and ETSI racks. Powered by 220/110V AC or 48V DC it integrates seamlessly in all environments.

Every chassis could accomodate up to 32 phone lines in up to 8 modules each contains 4 ports - either FXS or FXO.

Management controller

Management controller is based on the industry proven line of Atmel AVR processors. For monitoring and initial configuration there is RS232 port compatible with VT100 console. There is large (16x2) LCD for monitoring statuses.

Ethernet controller

Ethernet controller is based on Silabs SI2200 chip. It is fully compatible with all 10/100/1000 Base-T networks and supports half/full duplex negotation, automatic polarity detection and correction.

Communication modules

SpiderMUX have two variants of the communication modules:

• FXO (Foreign Exchange Office) - an interface that connects to the PSTN
• FXS (Foreign Exchange Subscriber) - an interface that connects to a standard phone set

Each communication module have four analog interfaces.
