Introduction 1-3The principal features of the OfficeConnect Remote are:n Easy to install, configure and support.n ISDN, 2B+D port, supporting Basic Rate interface oftwo 64 Kbps (or two 56 Kbps channels in the USA)and a 16 Kbps control channel.n Optional voice port.n Optional Leased line wide area network (WAN)access port.n Data terminal equipment (DTE) management portn Support for full IP and IPX routing.n Protocol transparent bridging.n Sophisticated data packet filtering to providenetwork security.n Provides NetWare protocol spoofing.n Data compression based on an optimized Lempel Zivalgorithm.n Remote and local management.n Flash erasable programmable read-only memory(EPROM), allowing the remote upgrading of theunits operating system.n Uses simple network management protocol (SNMP)and provides management information base (MIB) IIsupport.Benefits of ISDNISDN is an extension of the national and internationalpublic switched telephone network, which offers adigital end-to-end telecommunication system,providing a better quality service than available usingthe analog telephone network. The principalbenefits of ISDN are:n Fast call setup times, typically taking less than onesecond for national calls.n Greater bandwidth with multiple channels.The basic rate service, often referred to as ISDN 2,carries two 64 Kbps user channels, called B channelsand one 16 Kbps control channel called theD channel. The line service is presented into thecustomers premises through a standard RJ45 socket.A significant aspect of the ISDN service is that it can beprovided over the same wiring that was installed forthe original telephone service. Therefore, ISDN can bemade available relatively cheaply almost anywherethat previously had access to the analog system.The cost of installation and rental of basic rate ISDNlines has dropped to the point where it is extremelyattractive as regards cost and performance.Rc.bk : RC01.FRM Page 3 Thursday, July 10, 1997 9:53 AM
