Serial Device Concentration
The Cisco 2600 provides a cost-effective, flexible solution for
concentrating serial devices in remote locations. Async/sync ports
provide connections to serial devices such as SDLC concentration
devices, alarm systems, ATMs, debit/credit terminals and cash
registers. With full Cisco IOS protocol support including SDLC,
BSC, BTSUN, STUN, X.25, Frame Relay, and polled async, the
Cisco 2600 consolidates traffic from a wide variety of serial
devices over a single connection, eliminating costly dial-up BSC
links. Remote management is improved since only one network
management tool is needed. Network reliability for mission
critical devices is enhanced via dynamic routing capabilities.
In figure 10, a Cisco 2613 deployed in a bank branch office
connects the existing Token Ring LAN and up to 8 serial devices
to the corporate network. The Cisco 2612 in a retail store provides
an integrated solution for connecting Ethernet and Token Ring
LANs in addition to multiple point-of-sale devices. Whether the
application requires the two port async/sync WIC or the high
density async/sync network modules, each port can be
individually configured for synchronous or asynchronous
operation. Stacking the Cisco 2600 Series with Cisco LAN
switches such as the Catalyst 1900, 2820, and 2900XL Series
enables network administrators to manage remote branch office
environments efficiently using CiscoWorks and CiscoView
network management solutions.
