![]() ![]() ![]() Serial cables are not provided with the network module. EIA/TIA-530 and EIA/TIA-530A are available in DTE only. V.35 is available in either mode, with either gender at the network end. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.Īll serial interface types except EIA/TIA-530 and EIA/TIA-530A are available in DTE or DCE format: DTE with a plug connector at the network end, and DCE with a receptacle at the network end. The network end of each cable provides the physical connectors most commonly used for the interface. ![]() The Smart Serial cable uses a 12-in-1 Smart Serial connector designed by Cisco. See the "12-in-1 Smart Serial Cables" section for instructions on connecting the surge protector cable.Ī standard serial cable uses a universal 60-pin plug at the network module or WAN interface card end. Tip A cable providing surge protection (CAB-SS-SURGE) is also available from Cisco Systems for use with the NM-16A/S network module. (Some devices have a jumper to select DTE or DCE mode.) If you cannot find this information in your documentation, see Table 1 to help you determine the proper device type. The documentation that accompanied the device should tell you whether it is DTE or DCE. DTE devices usually connect to DCE devices. A DTE device does not provide a clock signal. A DCE device provides a clock signal between the device and the router.
