The following sections are provided for these new and changed commands:
The Cisco 2600 series routers is a new family of cost-effective, modular access routers designed to enable customers to easily adopt future technologies and scale to accommodate network expansion, thereby protecting technology investments. The Cisco 2600 series routers offer a broad range of packet telephony gateway solutions in one device, providing great flexibility, including data/voice integration, secure Internet and intranet access, and integrated LAN-to-LAN routing solutions.
The Cisco 2600 series is a key component of Cisco's data/voice/video integration strategy, enabling corporate customers to consolidate data, voice, and video traffic to reduce costs, deploy new business applications, and improve network performance. Cisco 2600 series routers use voice/fax modules, first introduced in the Cisco 3600 series routers, to take advantage of new applications, including Internet telephony, Web-based call centers, and desktop video.
This feature module describes the new and changed Show Commands for the Cisco 2600 series routers, including a command reference section that lists alphabetically the new and changed Show Commands with examples and sample output. Command syntax, parameters, and data types are explained and illustrated so that the new and changed Show Commands can be readily used and understood.
By deploying the Cisco 2600 series as customer premises equipment (CPE), service providers can offer broader managed service options including integrated voice and data, virtual private networks (VPNs), and outsourced dial access services. With support for multimedia, IP, serial and SNA traffic, the Cisco 2600 series routers promote large cost savings by eliminating the need for duplicate networks.
The Cisco 2600 series routers share modular interfaces with Cisco 1600 and Cisco 3600 series products, enabling customers and service providers to leverage and protect their investments in modular components that can be used in small, midsize, and regional branch offices. Components are field-upgradable, enabling customers to easily change network interfaces in the future as new services are deployed without performing "forklift upgrades" of their entire remote branch office solutions.
The Cisco 2600 series routers new Advanced Integration Module (AIM) slot further protects the customer's investment by offering an upgrade path to hardware-assisted data compression, data encryption, and other advanced services in the future. The Cisco 2600 series routers lower the cost of ownership by integrating the functions of CSU/DSUs, ISDN Network Termination 1 (NT1) devices, and other equipment found in remote branch office wiring closets into a single, compact unit.
Modular in design, interface configurations for the Cisco 2600 series are easily customized to accommodate a wide variety of network applications including secure extranet or VPN access and departmental dial services. When used in conjunction with the recently announced Cisco AS5800 carrier-class access concentrator, the Cisco 2600 series provides cost-effective termination of outsourced dial access services on the customer premises.
Cisco Voice Manager is a Java-based application that simplifies the process of deploying and managing end-to-end voice-enabled networks. It works with the Cisco 2600 series routers to provide unique capabilities for monitoring and managing end-to-end multiservice networks. Cisco Voice Manager takes the complexity out of large voice-over-IP networks by simplifying the process of configuring voice and fax interfaces and administering the voice dial plan. Cisco Voice Manager provides Call Detail Records, Call Volume Reports, and Active Call Reports, and measures quality of service (QoS) parameters such as delay, packet loss, and type of service.
The Cisco 2600 series also can be managed remotely using network management applications such as CiscoWorks and CiscoView. The Cisco Voice Manager also supports the voice-enabled Cisco 3600 series routers.
Advanced Integration Module (AIM)---The Cisco 2600 series routers new Advanced Integration Module (AIM) slot provides an upgrade path to hardware-assisted data compression, data encryption, and other advanced services in the future.
Asynchronous Transfer Mode (ATM)---International standard for cell relay in which multiple service types are conveyed in fixed-length (53-byte) cells. The fixed-length cells require lower processing overhead and allow higher transmission speeds than traditional packet switching methods.
Frame Relay---Standard switched data link layer protocol that handles multiple virtual circuits using HDLC encapsulation between connected devices. Frame Relay is generally considered to be a replacement for X.25.
Point-to-Point Protocol (PPP)---Protocol that provides router-to-router and host-to-network connections over synchronous and asynchronous circuits.
Switched Multi-Megabit Data Service (SMDS)---A high-speed, connectionless data transmission service that provides wide area connectivity through the public telephone network.
T3---Digital WAN carrier facility. T3 transmits DS-3 formatted data at 44.736 Mbps through the telephone switching network.

EXEC and Privileged EXEC
This command first appeared in Cisco IOS Release 10.3.
Context information for the c2600 is different than other router types because the c2600 runs with an M860 processor. Context information is processor- and architecture-specific. Software version and uptime information are not architecture specific.
The display from the show context command includes the following information:
This information is of use only to your technical support representative in analyzing crashes in the field. It is included here in case you need to read the displayed statistics to an engineer over the phone.
The following is sample output from the show context command following a system failure on a Cisco 2600 series router. See Table 2 for a description of the output display fields.
