MultiFRAD 100-Series User Guide
Introduction
The Multi-Tech Systems MultiFRAD 100-series (Model number FR111A) is a one-port Frame Relay
Access Device (FRAD) with 56K DSU that encapsulates non-packetized data from non-frame relay
devices into frame relay packets. The MultiFRAD enables access to common carrier frame relay
network services and to private frame relay networks. The access device is designed with an internal
56K Data Service Unit (DSU) that allows a single frame relay permanent virtual circuit (PVC) to be
connected to a 56K DDS circuit. On the receiving end of the communication link, the MultiFRAD
serves to strip away the frame relay control information so that the target device is presented with the
data packaged in its original form.
The versatility of the MultiFRAD provides for a smooth integration into frame relay of existing
equipment, e.g., multiplexers, routers, and legacy equipment such as cluster controllers, and for
asynchronous devices such as PCs running remote control software. The non-frame relay device
connects to the data port on the back of the MultiFRAD. The data port is capable of synchronous
data transmission up to 128 Kbps or asynchronous data transmission up to 115.2 Kbps. The network
connection is provided by the trunk port which directly connects to the frame relay network.
