HWIC-4ESW:

The HWIC-4ESW provides 4 switching ports.

WIC-1AM:

The WIC-1AM card features dual RJ-11 connectors, which are used for basic telephone service connections. The WIC-1AM uses one port for connection to a standard telephone line, and the other port can be connected to a basic analog telephone for use when the modem is idle.

WIC-1ENET:

The WIC-1ENET is a single-port 10 Mbps Ethernet interface card, for use with 10BASE-T Ethernet LANs.

WIC-1T:

The WIC-1T provides a single port serial connection to remote sites or legacy serial network devices such as Synchronous Data Link Control (SDLC) concentrators, alarm systems, and packet over SONET (POS) devices.

WIC-2AM:

The WIC-2AM card features dual RJ-11 connectors, which are used for basic telephone service connections. The WIC-2AM has two modem ports to allow multiple data communication connections.

WIC-2T:

The 2-port asynchronous/synchronous serial network module provides flexible multi-protocol support, with each port individually configurable in synchronous or asynchronous mode, offering mixed media dial support in a single chassis. Applications for asynchronous/synchronous support include: low speed WAN aggregation (up to 128 Kbps), dial-up modem support, Async or Sync connections to management ports of other equipment, and transport of legacy protocols such as Bi-sync and SDLC.

WIC-Cover:

The WIC cover plate provides protection for the internal electronic components. It also helps maintain adequate cooling by normalizing airflow.
