Cisco 5814 Dial Shelf

On the DSC card, only one common logic is active at any one time, which is identified by the CLK (clock) LED on the DSC card front panel. The active common logic is user selectable and is independent from each dial shelf controller card. This assures that if a DSC card needs replacing or if the slave DSC card becomes the master, clocking remains stable. The selected common logic should not be changed during normal operation, unless related hardware failure is suspected or diagnosed.

The Cisco 7206 router shelf supports call signaling for PRI interfaces; packet processing, and routing; and all commonly used high-speed LAN and WAN interfaces including Fast Ethernet (FE), Asynchronous Transfer Mode (ATM), High-Speed Serial Interface (HSSI), and Fiber Distributed Data Interface (FDDI). These interfaces are supported by common port adapters that are configured on the Cisco 7206 router shelf.

You can install and upgrade software remotely, without affecting current system operation. You can also upload and download configuration files remotely, without affecting current system operation. Remote access is enabled by use of SNMP, by a Telnet session to a console port on the router shelf, through the World Wide Web (WWW) interface, or through use of the optional system controller network management system.

The Cisco AS5800 can dynamically adjust any port to support any user configuration. Individual users can be authenticated as they connect to the system by use of one or more authentication servers using RADIUS and TACACS+ authentication protocols. Primary and backup authentication servers can define user authentication parameters using user domain and the number called. User profile information can also be configured to include time of day, number of simultaneous sessions, and number of B channels used.

When a remote user connects to the access server using a modem or an ISDN line, the user is authenticated, and establishes a session. Dynamic address assignment from an authentication server or static address assignment connects the user and has virtually no impact on service provider routing tables.

A remote LAN user can connect to the access server using an ISDN line or asynchronous serial connection, be authenticated, and establish a session. In addition to dynamic or static address assignment, this connection requires the traditional Cisco IOS software support for different routing protocols on different ports simultaneously, with virtually no impact on service provider routing tables.

A dial wholesale customer can connect to a Cisco AS5800, then tunnel PPP packet information to a retail service provider using dial virtual private network (dial VPN).

Cisco 5814 Dial Shelf

The Cisco 5814 dial shelf contains 14 slots (numbered 0 to 13 on the backplane) and can support as many as 10 modem cards, 2 T3 or 4 T1 trunk cards, and 2 dial shelf controllers (DSCs). Slots 12 and 13 in the dial shelf are dedicated slots for the DSCs. Metal guard pins on the backplane module prevent you from installing any other type of card in these two slots. The modular chassis supports online insertion and removal (OIR) and redundant power and includes environmental monitoring and feedback control.

The dial shelf contains CT1/CE1 or CT3 Primary Rate Interfaces (PRIs) that terminate ISDN and modem calls and break out individual calls from the appropriate telco services. Digital signal level 0 (DS0) or ISDN calls are terminated on the trunk card High-Level Data Link Control (HDLC) controllers, and analog calls are sent to modem resources on the modem cards. As a result, any DS0
