Voice/WAN Interface Cards Chapter 1 Overview of the Cisco MWR 1941-DC Router Each card also features protection switch solid state relays on the line interfaces, which together with redundancy logic and relay control added to the base Cisco IOS feature set on the MWR 1941-DC, provides T1/E1 Protection Switching between redundant routers. The MWR 1941-DC router provides three WAN interface slots. Additional information is contained in separate publications. • For information on the VWIC-2MFT-T1/E1-DIR VWICs, see the publication VWIC-2MFT-T1DIR, VWIC-2MFT-E1DIR Installation Instructions. • For software configuration information, see the publication Cisco MWR 1941-DC Software Configuration Guide. These manuals are on Cisco.com. See "Obtaining Documentation" section on page xi for more information. WIC-2A/S The dual-serial port WAN Interface Card (WIC-2A/S) provides higher levels of serial port density for a single WIC on the MWR 1941-DC router in a Cell Site DCN implementation. The low serial speed WIC-2A/S supports up to 128 Kbps synchronous or 115.2 Kbps asynchronous serial links. Each port on a WIC is a different physical interface and can support different protocols such as Point-to-Point Protocol (PPP) or Frame Relay and Data Terminal Equipment/Data Communications Equipment (DTE/DCE). This WIC supports mixed asynchronous and synchronous operation on a single card as well. These dual-serial port WICs feature Cisco's new, compact, Smart Serial connectors to support a wide variety of electrical interfaces when used with the appropriate transition cable. This includes: V.35, RS-232, RS-449, RS-530, RS-530A in male and female versions for both DTE and DCE devices. This feature provides easy configuration and reconfiguration as network requirements change, without the need of purchasing a different serial interface card. The WIC-2A/S provides two serial ports using the Smart Serial connector. • Asynchronous support with a maximum speed of 115.2 Kbps, and a minimum of 600 bps. If you need to run at speeds lower than 600 bps, use the AUX port instead. • Synchronous support with a maximum speed of 128 Kbps. Additional information is contained in separate publications. • For instructions on installing the WIC-2A/S and detailed information about the WIC-2A/S, see the Cisco Interface Cards Installation Guide. • For software configuration information, see the publication Cisco MWR 1941-DC Software Configuration Guide. These manuals are on Cisco.com. See "Obtaining Documentation" section on page xi for more information. Cisco MWR 1941-DC Mobile Wireless Edge Router Hardware Installation Guide 1-6 78-15827-06B0
