Gaithersburg, Maryland-headquartered Penril Datability Networks has announced three additions to its BRX range of bridge-routers, all based on Advanced Micro Devices Inc’s Am29000 series of RISC. The BRX5711 is a stand-alone bridge-router incorporating one Ethernet port and one 7Mbps serial wide area network port, while the BRX5712 adds a second 7Mbps port, and the BRX5722 features two Ethernet and two 7Mbps wide area network ports. All three support concurrent multiprotocol bridging and routing, with Flash program memory for local or remote network download, dial back-up and AUI-based Simple Network Management Protocol support, said the company. In addition, all the 5700 series include the company’s Constellation software that is capable of routing TCP/IP, Novell SPX/IPX, Xerox XNS, DECnet Phase V and AppleTalk.

The offerings also incorporate Simple Network Management Protocol Management Information Base II and Telnet support, enabling access remotely or locally via an async terminal. Password protection is provided with two levels of user privileges. Delivered with either 10Ba se-5 or with both 10Base-2 and 10Base-T local area network Ethernet connections with auto-sensing, the wide area network interfaces are switch-selectable between V.35 and non-V.35, with RS-232, RS-530 and RS-449 support.
