ADSL WICs
The DSL wide area network (WAN) interface cards (WICs) support one DSL line between a single customer premises equipment (CPE) subscriber and a central office.
Asymmetric digital subscriber line (ADSL) WICs are available in three variations:
•ADSL over POTS (WIC-1ADSL)
•ADSL over POTS with Dying Gasp support (WIC-1ADSL-DG)
•ADSL over ISDN with Dying Gasp support (WIC-1ADSL-I-DG)
The ADSL over POTS interface card is commonly used to provide ADSL services over ordinary telephone lines. The ADSL-over-ISDN interface card is used to provide ADSL services in those areas of the world that have extensive ISDN backbones already in place.
Note The term dying gasp refers to power status as defined in ITU-T standard G.991.2, section 7.1.2.5.3.
LEDs on ADSL WICs
ADSL WICs have three LEDs, which are shown in Figure 62 and are described in Table 14.

G.SHDSL WICs
The Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) cards support two or more DSL lines.
The G.SHDSL WICs are available in the following variations:
•The WIC-1SHDSL is a 1-port interface card that supports one pair of copper wire (2-wire G.SHDSL). It is compatible with Cisco G.SHDSL line cards in the Cisco 6015, Cisco 6130, Cisco 6160, or Cisco 6260 digital subscriber line access multiplexer (DSLAM).
•The WIC-1SHDSL-V2 and WIC-1SHDSL-V3 interface cards are 1-port cards. They support all G.SHDSL features, and supply two twisted pairs of wires to implement 4-wire (two-line) G.SHDSL. These WICs support dying gasp and wetting current. They also provide a higher symmetrical bandwidth and longer reach than 2-wire G.SHDSL.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 1-port G.SHDSL interface card (WIC-1SHDSL-V2 and WIC-1SHDSL-V3) only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.
LEDs on G.SHDSL WICs
The ADSL and G.SHDSL WICs have three LEDs, which are shown in Figure 63 and are described in Table 15.

G.SHDSL High Speed WICs (HWICs)
The G.SHDSL high speed WICs (HWICs) are available in the following variations:
•The G.SHDSL HWICs support up to four pairs of DSL: two inverse multiplexing over ATM (IMA) lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in groups and configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command.
– The HWIC-2SHDSL provides two ports of connectivity through one RJ-11 connector. It supports 1-Pair groups or 2-Pair groups.
–The HWIC-4SHDSL provides four ports of connectivity through one RJ-45 connector. It combines four ports of data into one line or two lines with either inverse multiplexing over ATM (IMA) groups or M-pair groups, and it supports 1-Pair groups or 2-Pair groups.
Note The Cisco HWIC-2SHDSL provides support for the Dying Gasp feature; however, the Cisco HWIC-4SHDSL does not provide support for this feature. The term dying gasp refers to power status as defined in ITU-T standard G.991.2, section 7.1.2.5.3.
LEDs on G.SHDSL HWICs
The G.SHDSL HWICs have 4 LEDs that indicate DSL functionality. Figure 64 and Figure 65 show the front panels and LEDs for the HWIC-2SHDSL and HWIC-4SHDSL. The LED descriptions follow.

The twisted-pair straight-through cable for customer premises equipment (CPE) applications is supplied. The RJ-45-to-RJ-45 BRI cable to connect the ISDN BRI ports on ADSLoISDN HWICs is not supplied. The two-line Y-cable for central office (CO) and 4-wire patch panel applications is not supplied.
Note The Y-cable must have the wires for pins 3 and 4 twisted together; wires for pins 2 and 5 must also be twisted together. Each pair goes to its own connector at the patch panel end.
Connecting a DSL Interface Card to the Network
See the following sections for information on connecting DSL interface cards to a network.
• Connecting the DSL Ports on WICs and HWICs
• Connecting the ISDN Ports on HWICs
• Connecting the SHDSL Port on the G.SHDSL HWICs
Connecting the DSL Ports on WICs and HWICs
Use a straight-through RJ-11 cable for this connection.
Table 19 shows the ADSL WIC and HWIC pinouts.
Note If you are connecting an ADSL interface card to an RJ-11 wall jack that has the DSL pair wired for pins 2 and 5, you must use an RJ-11 crossover cable (lavender with blue stripe). The RJ-11 crossover cable is orderable separately as a spare.
Table 20 shows the WIC-1SHDSL pinouts.
Table 21 shows the RJ-14C pinouts on the WIC-1SHDSL-V2 and WIC-1SHDSL-V3 interface cards.

To connect a DSL interface card to the WAN, complete the following steps:
Step 1 Confirm that the router is turned off.
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the HWIC-2SHDSL and HWIC-4SHDSL interface cards only to intra-building or unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Step 2 Connect one end of the cable to the ADSL or G.SHDSL port on the card.
Step 3 Connect the other end to the wall jack (RJ-11) at your site, as shown in Figure 68.
Figure 68 Connecting an ADSL Card to the Wall Jack
Alternately, when connecting a G.SHDSL card to a 4-wire patch panel, use a Y-cable as shown in Figure 69.
Figure 69 Connecting a G.SHDSL Card to a Patch Panel With a Y-Cable
Step 4 Turn on power to the router.
Step 5 To connect the card to the network, you must configure the DSL interface card in the router to the no shutdown state. Enter the no shut command in the router configuration. Verify that the CD LED comes on, indicating that the interface card is connected to the network.
Note Step 5 does not apply to the WIC-1SHDSL-V2 or WIC-1SHDSL-V3.
Connecting the ISDN Ports on HWICs
Use an RJ-45-to-RJ-45 BRI cable (not included) to connect the ISDN BRI port to an ISDN NT1 device. Refer to the online document Cisco Modular Access Router Cable Specifications for pinouts.
To connect an ISDN BRI S/T port to the WAN, follow these steps:
Step 1 Confirm that the router is turned off.
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the HWIC-ADSL-B/ST or HWIC-ADSLI-B/ST ISDN BRI S/T port only to intra-building or unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Step 2 Connect one end of a straight-through RJ-45-to-RJ-45 cable to the S/T interface.
Step 3 Connect the other end of the cable to the NT1 device, as shown in Figure 70.
Figure 70 Connecting the BRI S/T Port
Step 4 Connect the NT1 device to the ISDN wall jack according to the documentation that came with the NT1 device.
Step 5 Turn on power to the router.
Connecting the SHDSL Port on the G.SHDSL HWICs
Connect Cisco G.SHDSL HWICs as described next:
•Cisco HWIC-2SHDSL—Use a standard RJ-11 straight-through cable to establish connection between the HWIC and a network device.
•Cisco HWIC-4SHDSL—Use a standard RJ-45 straight-through cable to establish connection between the HWIC and a network device.
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the HWIC-2SHDSL and HWIC-4SHDSL interface cards only to intra-building or unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Figure 71 shows the RJ-45 pin assignment. Table 22 identifies the RJ-45 signal assignment by pin.
Caution Inserting an RJ-11 connector into the Cisco HWIC-4SHDSL port may deform pins 1 and 8, which may prevent solid contact between the connector and the plug in subsequent connections. If solid contact is prevented, line -1 tip and line -3 ring will not work properly.

Using POTS Splitters and Microfilters with an ADSL-over-POTS WIC (WIC-1ADSL)
POTS splitters and microfilters apply to the ADSL-over-POTS WIC only. They are used on telephone lines to ensure voice- and data-call quality. POTS splitters result in the best data and voice performance when the router and the telephone are used on the same telephone line.
POTS Splitters
A POTS splitter (also called a splitter) is installed on a telephone line that is connected to both data (high-frequency) and voice (low-frequency) devices. The splitter routes the high-frequency and low-frequency signals on the telephone line to the correct device. Signals intended for the router can disrupt voice calls; signals intended for voice calls can affect router operation.
Most splitters must be installed by the telephone company; however, some splitters can be installed by the customer. If you are not sure what type of splitter to use, contact your service provider.
Figure 74 is an example of a type of POTS splitter that is installed at the customer premises by the customer. Other types of POTS splitters are installed by the telephone company on an exterior wall of the customer premises.
Figure 74 POTS Splitters
Microfilters
Microfilters are installed on telephones to improve voice-call quality when voice and data equipment are using the same telephone line (twisted pair). You should use microfilters only when the two following conditions exist:
•The documentation for the telephone you are using with the router states that microfilters should be used with the phone.
•Poor telephone call quality can be resolved by installing a microfilter on the phone line.
Figure 75 shows one type of microfilter.
Figure 75 Microfilter
Common Splitter and Microfilter Configurations
This section describes the most common scenarios for using splitters and microfilters. The scenarios are listed from most common to least common.
Telephone Company-Installed Splitter
This scenario is described below and illustrated in Figure 76.
•The telephone company has provisioned a single copper pair to be used by both the telephone (POTS) service and the router with a DSL interface card, so a POTS splitter must be installed.
•The splitter is installed by the telephone company on the customer premises. This type of splitter is also referred to as a network interface device (NID).
•The router and telephone are on separate lines (twisted pair) to the splitter.
•The router and telephone share the same telephone line (twisted pair) to the telephone company.
Figure 76 Telephone Company-Installed Splitter
Customer-Installed Splitter
This scenario is described below and illustrated in Figure 77.
•The telephone company has provisioned a single copper pair to be used by both the telephone (POTS) service and the router with a DSL interface card, so a POTS splitter must be installed.
•The splitter is installed by the customer on the customer premises.
•The router and telephone are directly connected to the splitter, which is connected to the telephone line.
•The router and telephone share the same telephone line (twisted pair) to the telephone company.
•For optional telephones connected through the splitter, microfilters are optional. They should be installed only if they improve telephone call quality.
•For telephones connected directly to the telephone line, microfilters are required.
Figure 77 Customer-Installed Splitter
Router and Telephone Using Separate Telephone Lines
This scenario is described below and illustrated in Figure 78.
•The telephone company has provisioned a single copper pair to be used exclusively by the router with a DSL interface card and a separate copper pair to be used exclusively by the telephone (POTS) service; therefore, neither a POTS splitter nor a microfilter is needed.
•The microfilter is optional; it should be installed only if it improves telephone call quality.
