The Bay Networks BayStack Access Node (AN) and Access Node Hub (ANH) routers cost-effectively connect small remote offices and ensure network availability while minimizing network operating costs.
Typical connectivity requirements of remote offices are supported by the AN's LAN interfaces (Ethernet and Token Ring) and serial interfaces (Synchronous and ISDN BRI interface). The fully managed BayStack ANH supports either 8 or 12 10BASE-T repeater ports, as well as Synchronous and ISDN BRI interfaces, reducing equipment and management complexity.
In all AN and ANH configurations the serial interfaces provide remote office network design flexibility. For mission-critical applications, they facilitate Dial Back-up and Bandwidth-on-Demand support. In addition, Dial-on-Demand functionality enables ANs to extend network availability on an as-needed basis to small remote sites, minimizing WAN service costs. Optionally, Synchronous interfaces can be used for SDLC, allowing both IBM SNA and multiprotocol LAN traffic over one consolidated WAN link to the internetwork backbone.
The AN and ANH easily integrate with the enterprise internetwork, supporting Bay Networks Routing Services (BayRS), which provides support for all major LAN and WAN protocols. The Motorola 68360 processor, used in the AN/ANH's highly integrated design, easily maintains high forwarding and filtering rates regardless of the number of protocols and network interfaces used - even when processing SNMP management inquiries.
The AN and ANH are easily configured and monitored via Bay Networks UNIX-based Optivity Internetwork or Windows-based EZ Internetwork, which provides comprehensive node configuration, monitoring, and control. Bay Networks Optivity Design & Analysis enhances these solutions by providing standards-based RMON tools that ease problem resolution, enhance interoperability, and protect investment. The AN/ANH's comprehensive Ethernet RMON support allows remote networks to be monitored from a central location.
The AN and ANH are critical parts of the BayStack product family. Combined with the BayStack 10BASE-T Stackable Hubs, 100BASE-T hubs, and the Ethernet Workgroup Switch, the AN and ANH deliver a robust, scalable solution for remote offices and Internet access.
Benefits and Features
- Flexible Network Design: The BayStack AN and ANH meet the connectivity needs of remote offices while providing an extra level of availability. Additionally, the AN/ANH support SNA/SDLC integration. Multiple network design options are available.
- Minimizes Network Operating Costs: BayStack ANH configurations integrate the function of both a router and a hub into one platform, simplifying equipment and management requirements. The EZ-Install feature reduces installation time and expense by enabling the AN/ANH to get its IP address and configuration from a central site. Remote site software maintenance time and expense are also minimized by the AN/ANH's EZ-Update feature, which allows software updates to be downloaded from a central site. Problems at remote sites can also be solved from a remote site via the AN/ANH's standards-based Ethernet RMON (RFC 1271) support.
Data Compression support also minimizes costs by enabling lower cost links to achieve the throughput rates of higher cost links. Small remote offices can also connect to the internetwork on an as-needed basis via the AN/ANH's Dial-on-Demand support.
- Maintains Network Availability: Uninterrupted remote office network operation is ensured by the AN/ANH's Dial Back-up feature, which provides a backup link to the backbone if the primary link fails. The AN/ANH's dynamic reconfiguration support allows on-line software changes to be made without disrupting network operation. Data Compression, Traffic Prioritization, and Uniform Traffic Filters increase available bandwidth and optimize network efficiency. Bandwidth-on-Demand support maintains routing performance by establishing supplemental dial connections if the primary link becomes congested. The AN/ANH's support of RMON's remote network monitoring and analysis capabilities enables malfunctions to be viewed and corrected before they cause major problems.
- Extends Remote Office Connectivity: Bay Networks Routing Services' (BayRS) support of all major routing and bridging protocols maximizes connectivity and interoperability in multivendor, multiprotocol environments. Additionally, the AN and ANH consolidate SNA and NetBIOS traffic across the multiprotocol internetwork by supporting DLSw (RFC 1434), the industry-standard IBM transport protocol, and APPN. Furthermore, enterprise-wide connectivity is extended to small remote sites through Dial-on-Demand support.
- Integrates WAN transmission device options including 56K or T1/E1/ FT1/FE1 DSU/CSUs, ISDN BRI with or without NT1, and V.34 modems
- Scales to match changing requirements, by means of a modular architecture with mix-and-match interface modules, processors, and redundancy options
- Offers value-added adjunct features, such as an integral V.34 modem for analogue dial service routing or out-of-band console interface access, redundant power, removable PCMCIA flash memory, an RMON hardware probe, or E1 CSU/DSU support
- Enables small sites to configure two "communities" as separate LANs, providing network security via LAN "firewall" techniques
