The Cisco 5300 provides support for 48 DoV calls, 48 modem calls, and 96 data calls. The first two PRIs are configured to handle voice calls as data and the last two are configured to handle voice calls as modem calls. http://www.cisco.com/warp/customer/793/access_dial/4.html (available to registered users) --------------------------------------------------- Sample Configuration: This sample configuration shows how to use DOV with a BRI-to-BRI connection.

These PCs are typically configured to get all IP-related information (IP address, Domain Name System [DNS] server, and so on) from the NAS. Users frequently find that their MS Windows PCs do not show the desired subnet mask and gateway for a PPP connection established using dialup networking. That information is obtained when running the Windows IP Configuration program (winipcfg) on Windows 95 and 98 machines, or running the Windows NT Configuration program (ipconfig)on Windows NT machines. http://www.cisco.com/warp/customer/74/161.html (available to registered users) --------------------------------------------------- Tech Tip: This document describes how to log in to a Cisco (IDS) sensor through the COM port. http://www.cisco.com/warp/customer/707/23.html (available to registered users) --------------------------------------------------- Configuration Cookbook: This is a great source of configurations for Cisco routers from the Cisco 700 series up to the Cisco AS5200 and AS5300 access routers. http://www.cisco.com/warp/customer/793/access_dial/ (available to registered users) --------------------------------------------------- Sample Configuration: This sample configuration shows a stack of access servers that rely on an off-load server to terminate all PPP connections (multilink [MP] and non-MP). The off-load server is in charge of all PPP (MLP and non-MLP) connections and the access servers handle all call processing (ISDN and modem). http://www.cisco.com/warp/customer/793/access_dial/6.html (available to registered users) CISCO 3600 Tech Tip: How async lines are numbered in Cisco 3600 series routers Async lines are not numbered linearly on the Cisco 3600 platform. Because of the modular design of these routers, there are fixed line ranges for each slot, and each slot is allocated 32 line numbers. Therefore, the configuration does not change when async lines are added or removed from other slots. http://www.cisco.com/warp/customer/471/108.html (available to registered users) CISCO 7200 Field Notice: End of life of some components necessitated replacement with new components. Some of the new components, in turn, necessitated the relayout of the print circuit board (PCB), changes affecting the cosmetic appearance of the front panel. There are no functional, form, or mechanical fit changes. http://www.cisco.com/warp/customer/770/fn9431.html (available to registered users) CATALYST 5000 Tech Tip: http://www.cisco.com/warp/customer/473/8.html (available to registered users) --------------------------------------------------- Tech Tip: There are three methods for connecting management terminals to Supervisor Engines, depending on the engine you have installed. Each method is described in this document. http://www.cisco.com/warp/customer/473/9.html (available to registered users) --------------------------------------------------- Tech Tip: The Catalyst 5000 switch allows you to configure several descriptive system parameters to ease in the administration of internetworking equipment. http://www.cisco.com/warp/customer/473/6.html (available to registered users) IGX Switch Tech Tip: This tech tip explains the functional differences that exist between Models A, B, and C of the channelized voice module (CVM) on an IGX switch. http://www.cisco.com/warp/customer/74/163.html (available to registered users) MGX-8850 Tech Tip: This tech tip briefly explains the importance of proper impedance control within the backplane of the MGX8850 and how the backplane provides that control. http://www.cisco.com/warp/customer/74/162.html (available to registered users) WS-X5012 LINE CARDS Field Notice: Some WS-X5012 cards have failed in the field because of internal shorting of the printed circuit board assembly (PCBA) fabrication after several months of operation. When a failure occurs, the card will cease to function and will likely disrupt the operation of the switch in which it is installed. The failure may also cause damage to the backplane, rendering the switch inoperable. http://www.cisco.com/warp/customer/770/fn9151_12081999.shtml (available to registered users) --------------------------------------------------- SOFTWARE PRODUCTS (Not Cisco IOS software) ___________________________________________________ White paper: The Cisco ICM system is a network-based application that relies heavily on the customer's network to provide connectivity between the different parts of the system.
