Cisco smart serial connections are used and utilized by the Hwic-1t, Hwic-2t, Hwic-2t, and Hwic-2a/s. Table 3 contains a list of the cables that are supported. There is a rj-45 connection used by the hwic-1dsu-t1. An eia/tia-232, eia/tia-449, v.35, x.21, data terminal equipment/data communications equipment (dte/dce) interface, eia-530 dte interface, or nonreturn to zero/nonreturn to zero inverted (nrz/nrzi) serial interface can be provided to a Cisco modular router by the 1-port serial hwic (hwic-1t), which is depicted in figure 1. The 2-port serial hwic (hwic-2t), which is depicted in figure 2, is shown in figure 2. router#show version 1 virtual private network (vpn) module 1 cellular interface dram configuration is 64 bits wide with parity enabled.

Customers are able to deploy many applications with the use of these hwics, including dial access server, console server, legacy protocol transfer, and WAN access. When it comes to typical networking issues, such as remote network administration, external dial-modem access, low-density WAN aggregation, legacy protocol transfer, and high-port-density support, you have the ability to mix and combine hwics in order to design cost-effective solutions.
