The Cisco 2505, 2507, and 2516 are hub/routers that enable remote offices to provide both LAN and internetwork connectivity. These hub/routers combine the functions of a stand alone hub and router in one chassis to provide simpler setup, improved service ability and reliability, and integrated remote Simple Network Management Protocol (SNMP) network management.
Another note, through the BRI port, dial-up access is provided for backup or for low-cost, high-speed connectivity to private or public inter-networks. The two high-speed, synchronous serial WAN interfaces on each Cisco model deliver unprecedented flexibility, enabling access to leased lines, packet- and circuit-switched services, as well as -support of legacy systems such as IBM Synchronous Data Link Control (SDLC) devices.
All models use low-cost, unshielded twisted-pair cable wired in a star configuration for easy installation and offer from 8 (Cisco 2505), 14 (Cisco 2516), or 16 (Cisco 2507) Ethernet 10BaseT hub ports. No hub-to-router cabling is require. Everything is neatly contained in one compact desktop, rack-, or wall-mounted chassis.
Next, the Cisco 2516 includes an Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) port, allowing dial-up, high-speed access up to 128 kilobits per second (kbps). Cisco 2516 allows easy expansion by enabling additional units to be daisy-chained together using one of the 10BaseT ports.
Cisco 2500 Router hub/routers can be ordered with any of seven Cisco IOS feature sets. They range from low-cost, IP-specific feature sets to Enterprise (EN) sets that contain the full Cisco IOS. Each set includes Cisco’s unique AutoInstall capability, the “plug-and-play” router feature that allows rapid, economical router installation with -minimal expertise at remote sites.
Cisco 2500 Router access server series enables users to connect asynchronous devices such as dumb terminals, modems, router consoles, slot machines, and Integrated Services Digital Network (ISDN) terminal adapters (TAs) into a routed network. Running the same Cisco IOS software that runs the backbone of the Internet on a high-performance router engine, this product family also gives users integrated synchronous serial ports to backhaul routed traffic through high-speed T1/E1 lines.
