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 standard for electromagnetic compatibility and safety, connect the HWIC-ADSLI-B/ST, HWIC-2SHDSL, HWIC-4SHDSL, and HWIC-4SHDSL-E 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 8.
Figure 8 Connecting an ADSL Card to the Wall Jack
Alternatively, when connecting a G.SHDSL card to a 4-wire patch panel, use a Y-cable as shown in Figure 9.
Figure 9 Connecting a G.SHDSL Card to a Patch Panel With a Y-Cable
Figure 10 Connecting a G.SHDSL EFM 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 This step does not apply to the WIC-1SHDSL-V2, WIC-1SHDSL-V3, and HWIC-4SHDSL-E.
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. See 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 11.
Figure 11 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 and EHWICs
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, HWIC-4SHDSL EFM, and EHWIC-4SHDSL-EA—Use a standard RJ-45 straight-through cable to establish connection between the HWIC or EHWIC and a network device.
|
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the HWIC-2SHDSL, HWIC-4SHDSL, HWIC-4SHDSL-E 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.

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 is installed on a telephone line connected to both data and voice devices. The splitter routes the data and voice 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 15 is an example of a type of POTS splitter that is installed at the customer premises by the customer.
Figure 15 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 documentation requires their use.
Figure 16 shows one type of microfilter.
Figure 16 Microfilte
Telephone Company-Installed Splitter
The scenario below describes Figure 17.
•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 17 Telephone Company-Installed Splitter
Customer-Installed Splitter
The scenario below describes Figure 18.
•The telephone company has provisioned a single copper pair used by 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 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 18 Customer-Installed Splitter
Router and Telephone Using Separate Telephone Lines
The scenario below describes Figure 19.
•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.
