Prerequisites Requirements There are no specific requirements for this document. Components Used This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions For more information on document conventions, see the Cisco Technical Tips Conventions. EIA/TIA−449 Speed and Distance Limitations The use of balanced drivers allows EIA/TIA−449 signals to travel greater distances than the EIA/TIA−232 standard. The table below lists the standard relationship between baud rate and maximum distance for EIA/TIA−449 signals. These limits are also valid for V.35 and X.21. Data Rate (Baud) 2400 Distance (Feet) 4,100 Distance (Meters) 1,250 4800 9600 19200 38400 56000 T1 2,050 625 1,025 312 513 156 256 78 102 31 50 15 Caution: The EIA/TIA−449 and V.35 interfaces support data rates up to 2.048 Mbps. Exceeding this maximum could result in loss of data and is not recommended. Serial Cable CAB−449MT This section presents the cable assembly and pinouts for the CAB−449MT serial cable. Note: The cable itself identifies the Cisco router as a data terminal equipment (DTE) or data communications equipment (DCE) device to other devices in the network; for this reason, it is important to select the correct product number from the table below. The cable gender for this product (part number 72−0795−01) is Male DB−60 to Male DB−37, mode − DTE. The CAB−449MT cable is used in the Cisco 7000 family, Cisco 4000 series, Cisco 3600 series, Cisco 2500 series, Cisco 1600 series, Cisco access servers, and AccessPro PC cards. This cable has a male DB−60 connector on the Cisco end and a male DB−37 connector on the network end. EIA/TIA−449 Serial Cable Assembly EIA/TIA−449 DTE Cable Pinouts The table below shows the EIA/TIA−449 DTE cable pinouts (DB−60 to DB−37).
