Cisco serial and asynchronous modules are designed to provide highly flexible connectivity options for the Cisco 1800, 1900, 2800, 2900, 3800, and 3900 Series Integrated Services Routers (ISRs). These interface cards allow businesses to address a variety of networking requirements, ranging from remote network management and dial access to low-density WAN aggregation.

By offering a modular approach, these cards enable organizations to tailor their networking infrastructure to specific needs. Whether the goal is to transport traditional protocols across a modern TCP/IP network or to manage remote devices through out-of-band console access, these modules provide a cost-effective and scalable solution for diverse branch-office environments.

Product overview

The Cisco portfolio includes several specialized modules to accommodate different port densities and protocol requirements. The available options consist of the Cisco 4-Port Serial HWIC (HWIC-4T), the Cisco 4-Port Asynchronous/Synchronous HWIC (HWIC-4A/S), and the Cisco 8-Port Asynchronous/Synchronous HWIC (HWIC-8A/S-232).

Additionally, for environments requiring higher asynchronous port counts, Cisco offers the 8-Port Asynchronous HWIC (HWIC-8A), the 16-Port Asynchronous HWIC (HWIC-16A), and the 32-Port Asynchronous Serial Service Module (SM-32A). These modules utilize various high-density cabling solutions, such as Smart Serial and high-density 8-port connectors, to ensure efficient space utilization within the compact form factor of the router slots.

Features and benefits

  • WAN Aggregation: Supports serial speeds of up to 8 Mbps per port, making it ideal for aggregating WAN connections from remote sites.
  • Protocol Convergence: Facilitates the transport of traditional protocols—such as SNA, SDLC, Bisync, and X.25—over TCP/IP networks, eliminating the need for expensive dedicated leased lines.
  • Remote Management: Asynchronous ports enable out-of-band management of console and craft ports, allowing operators to manage remote network devices from a centralized location.
  • Dial Access Support: Provides the ability to connect to external dial modems, serving as a reliable solution for low-density dial access servers.
  • Flexible Connectivity: Offers a wide range of serial protocol support, including EIA-232, EIA-449, EIA-530, EIA-530A, V.35, and X.21.
  • High Port Density: Designed to maximize port counts within a single HWIC or SM slot, optimizing the physical footprint of the router.
  • Broad Compatibility: Compatible with a wide range of Cisco ISR platforms and supported across all Cisco IOS Software feature sets.

Product Overview

Serial and asynchronous modules provide highly flexible connections for Cisco 1800, 1900, 2800, 2900, 3800, and 3900 Series Integrated Services Routers (ISRs). These modules help customers enable applications such as WAN aggregation, transport for traditional protocols, console servers, and dial access servers. Customers can mix and match modules to tailor cost-effective solutions for common networking problems such as remote network management, external dial-modem access, low-density WAN aggregation, transport for traditional protocols, and high-port-density support.
Cisco offers the following serial and asynchronous modules:

• Cisco 4-Port Serial High-Speed WAN Interface Card (HWIC-4T): Four high-speed serial ports (Figure 1A)

• Cisco 4-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-4A/S): Four low-speed synchronous/asynchronous ports (Figure 1B)

• Cisco 8-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-8A/S-232): Eight low-speed synchronous/asynchronous ports, EIA-232 only (Figure 1C)

• Cisco 8-Port Asynchronous High-Speed WAN Interface Card (HWIC-8A): Eight asynchronous EIA-232 ports (Figure 1D)

• Cisco 16-Port Asynchronous High-Speed WAN Interface Card (HWIC-16A): Sixteen asynchronous EIA-232 ports (Figure 1E)

• Cisco 32-Port Asynchronous Serial Service Module (SM-32A): Thirty-two asynchronous EIA-232 ports Figure 1F)

Common Applications

These highly flexible interface cards enable several important applications.

WAN Aggregation

Serial interfaces can be used to aggregate WAN connections from remote sites. With support for serial speeds of up to 8 Mbps per port, the Cisco 4-Port Serial HWIC is well suited for low- and medium-density WAN aggregation (Figure 2).

Figure 2. WAN Aggregation

Transport for Traditional Protocols

Serial and synchronous/asynchronous ports are well suited for transporting traditional traffic across a TCP/IP network. This capability enables network convergence (Figure 3), eliminating the need for costly separate leased lines for this traffic. Traditional protocols supported by Cisco IOS Software include:

• Systems Network Architecture (SNA) and Synchronous Data Link Control (SDLC) Protocol

• Binary Synchronous Communications (Bisync) Protocol

• X.25 Protocol

Figure 3. Network Convergence

Console and Terminal Server

Asynchronous ports provide highly flexible connections that allow access to EIA-232 devices across a TCP/IP network. This capability allows out-of-band management of console and craft ports, allowing the network operator to manage a network of remote devices from a central location (Figure 4).

Figure 4. Managing Multiple Remote Devices from a Single Location

Dial Access Server

Asynchronous HWICs can connect to external dial modems to provide low-density dial access servers (Figure 5).

Connectors and Cabling

Serial and asynchronous HWICs have connectors and cabling that allow high port densities in the compact HWIC form factor. Tables 1 through 4 show connector and cabling specifications.

Smart Serial Cabling

The Cisco 4-Port Serial HWIC and 4-Port Asynchronous/Synchronous HWIC each have four Smart Serial ports. These ports use the same connectors and cabling as the 2-port Serial WIC (WIC-2T) and 2-port Async/Sync WIC(WIC-2A/S).

High-Density Synchronous/Asynchronous Cabling

The Cisco 8-Port Asynchronous/Synchronous HWIC uses two high-density 4-port connectors. Each connector supports four ports of EIA-232 with data communications equipment (DCE) or data terminal equipment (DTE) interfaces. All four ports on one cable use the same DTE and DCE mode.

High-Density Asynchronous Cabling

The Cisco 8-Port Asynchronous HWIC and 16-Port Asynchronous HWIC use one (HWIC-8A) or two (HWIC-16A) high-density 8-port connectors. The 8-port asynchronous cable provides the high-density connector on one end and eight RJ-45 plugs on the other. RJ-45- to DB-25 modular adapters are used to convert the RJ-45 to a DB-25 DTE or DB-25 DCE connection.
