Step 4 Router(config-voicecard)# codec complexity Specify the compression complexity for the voice {high |medium} card.One complexity type is allowed per router. Step 5 Router(config-voicecard)# exit Exit back to global configuration mode. Step 6 Router(config)# Ctrl-z Return to Step 3 if your router has more than one voice card that you need to configure. When you finish configuring interfaces, return to enable mode. Configuring T1 (FT1) WAN Interface Cards The 1-port T1 and fractional (FT1) WAN interface card includes an integrated data service unit/channel service unit (DSU/CSU) and can be configured either for full T1 service at 1.544 Mbps or for fractionalized T1 service. You can configure the interfaces on your T1 WAN interface card manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility. Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN connection on both ends and the router does not have a valid configuration file stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host. Before you begin configuring the BRI interface, make sure you: • Connect a console to the router. • Power on the router. Default Configuration The Cisco IOS software provides the following default configuration for CSU/DSU- and T1-specific parameters: service-module t1 clock source line service-module t1 data-coding normal service-module t1 timeslots all speed 64 service-module t1 framing esf 3-18 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
