PathBuilder S310 The PathBuilder S310 is a feature-restricted version of the PathBuilder S330 Features providing remote site CPE access. Its physical appearance is the same as that of the

PathBuilder S330 but its software does not enable all the ports. You can upgrade from the PathBuilder S310 to the PathBuilder S330 (multi-mode fiber model) simply by purchasing software.

The PathBuilder S310 base platform offers the following features:

■Single T1/E1 UNI.

■Multiple connections to Ethernet segments over ATM WAN and support of bridging, including learning, aging, and filtering, through the Ethernet module.

■Support of Frame Relay (service and network) interworking, ATM DXI, and SDLC/HDLC pass-through, through the high-performance serial frame data interface.

■Three expansion slots, allowing you to add other advanced features, such as T1-DSX or E1 CBR for voice and video, voice compression, or DS3/E3.
