Connecting Serial Interface Cards to a Network

This chapter describes how to connect Cisco serial interface cards to a network and contains the

following sections:

• Serial WAN Interface Cards (WICs), page 3-1

• Serial High Speed WICs (HWICs), page 3-5

• Related Documentation, page 3-11

Serial WAN Interface Cards (WICs)

This section describes how to connect 1- and 2-port serial Cisco WAN interface cards (WICs) to a

network and contains the following subsections:

• 1- and 2-Port Serial WICs, page 3-1

• 2-Port Asynchronous/Synchronous Serial WIC, page 3-2

• Connecting 1- and 2-Port Serial WICs to a Network, page 3-3

1- and 2-Port Serial WICs

The 1-port serial WIC (WIC-1T), shown in Figure 3-1, and the 2-port serial WIC (WIC-2T), shown in

Figure 3-2, provide an EIA/TIA-232, EIA/TIA-449, V.35, X.21, data terminal equipment/data

communications equipment (DTE/DCE), EIA-530 DTE, or nonreturn to zero/nonreturn to zero inverted

(NRZ/NRZI) serial interface to a Cisco modular router.

Note In Cisco 3600 series and Cisco 2600 series routers, the 2-port serial WIC supports both asynchronous

(up to 115.2 kbps) and synchronous (up to 2.048 Mbps) data rates. The 1-port serial WIC supports only

synchronous data rates up to 2.048 Mbps.

Note In the Cisco 1720 series router, the 1-port and 2-port serial WICs support both asynchronous (up to 115.2

kbps) and synchronous (up to 2.048 Mbps) data rates.

Chapter 3 Connecting Serial Interface Cards to a Network Serial High Speed WICs (HWICs) 4-Port Multiprotocol High Speed HWIC The 4-port multiprotocol high speed HWIC (HWIC-4T) is illustrated in Figure 3-6. Protocols supported are Async (SLIP), Async (PPP), HDLC, Bisync, and transparent. Interfaces supported are as follows: • In both DTE and DCE formats: V35, X21, RS-232, and RS-449 • In DTE format only: EIA-530 and EIA-530A The maximum data rate supported is 8 Mbps per port.

Chapter 3 Connecting Serial Interface Cards to a Network Serial High Speed WICs (HWICs) Types of Cables for Serial HWICs The 4-port serial HWICs have 26-pin 12-in-1 Cisco smart serial ports, whereas the 8- and 16-port serial HWICs have 68-pin serial ports. Use the correct cable for your serial HWIC. Cables for 4-Port Serial HWICs The 4-port serial HWICs use Cisco smart serial cables.
