Cisco AS5850 Product Overview
The Cisco AS5850 is a high-density, ISDN and modem WAN aggregation system that provides both
digital and analog call termination. It is intended to be used in service provider dial point-of-presence
(POP) or centralized enterprise dial environments.
The gateway components include hybrid trunk and port-handling cards (both functions are handled by
different components in the same slot), dedicated port-handling cards, dedicated trunk cards, route
swit

You can install multiple ingress interface cards of like types and configure the Cisco AS5850 for card or port level redundancy, depending on your needs. Trunk and port handling cards are tied together using several time-division multiplexing (TDM) buses on the backplane. Each line card is also connected, through point-to-point packet buses, to a central switch

Chapter 1 Cisco AS5850 Product Overview Field-Replaceable Units In systems with two RSCs, the way the RSC uses the backplane buses will depend on the mode the system is operating in. Sometimes one RSC will control all the backplane DS0s and sometimes their use will be divided between the RSCs. Environmental Monitoring Environmental monitoring for the full chassis is carried out by both RSCs. This means that warnings about overheating cards go to both RSCs, regardless of which one owns

The active common logic is user-selectable and is independent from each RSC card. This assures that if you need to replace an RSC, or if the slave RSC becomes the master, clocking remains stable. The selected common logic should not be changed during normal operation unless a hardware failure is suspected or diagnosed in the
