ISDN BRI S/T WICs Overview

The ISDN BRI S/T WICs connect to an ISDN network through an external NT1 device. This interface is also known as an S/T interface. There are three ISDN BRI S/T WICs:


Note You can distinguish between WIC36 and WIC models of an ISDN BRI WIC by the location and labeling of the LEDs and by the number and location of cutouts in the faceplate.


1-port ISDN BRI WIC with S/T interface (WIC36-1B-S/T) (see Figure 44)

1-port ISDN BRI WIC with S/T interface (WIC-1B-S/T) (see Figure 45)

1-port ISDN BRI WIC with S/T interface, version 3 (WIC-1B-S/T-V3) (see Figure 46)


Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 1-port ISDN BRI WIC with S/T interface, version 3 (WIC-1B-S/T-V3) only to intra-building or non-exposed wiring or cabling. 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.

Prerequisites for Connecting an ISDN BRI S/T WIC to a Network

Before connecting a WIC to the network, ensure that the WIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the WIC to the network. This section describes the preparation necessary before connecting an ISDN BRI S/T WIC to the network.

Installing a Cisco ISDN BRI S/T WAN Interface Card

Install the Cisco WIC according to the instructions in Installing Cisco Interface Cards in Cisco Access Routers.


Note Older WIC36-1B-S/T, WIC36-1B-U, CPAWIC36-1B-S/T, or CPAWIC36-1B-U interface cards mount only in the W1 slot of a 2-slot network module and provide a single BRI interface. Newer WIC-1B-S/T or WIC-1B-U interface cards can mount in either slot of a 2-slot network module. For more information on BRI network modules, see the network module documentation located at:
http://www.cisco.com/en/US/products/hw/modules/ps2797/tsd_products_support_series_home.html


Grounding

Ensure that the equipment you are working with is properly grounded. For instructions on grounding your WIC, see Installing Cisco Interface Cards in Cisco Access Routers.

Cables

Use a straight-through RJ-48C-to-RJ-48C BRI cable (not included) to connect an ISDN BRI S/T WIC to a network.

Setting Jumpers on ISDN BRI WICs

The WIC-1B-S/T, WIC-1B-S/T-V3, and WIC-1B-U interface cards do not have termination jumpers.


Note For long-distance point-to-point configuration, and for the last station in point-to-multipoint configuration, use an external 100-ohm terminator.


The WIC36-1B-S/T, WIC36-1B-U, CPAWIC36-1B-S/T, and CPAWIC36-1B-U interface cards have two termination jumpers, labeled J1 and J2. Before installing a WIC36-1B-S/T, WIC36-1B-U, CPAWIC36-1B-S/T, or CPAWIC36-1B-U interface card, ensure that the termination jumpers are set appropriately for your installation.

The jumpers are factory-configured in the B position. Keep the jumpers in this position to use the ISDN BRI WIC in a point-to-point connection or as the last device on the line of a passive-bus connection. Set the termination jumpers to the A position to use the ISDN BRI WIC in a passive-bus connection in which it is not the last device on the line. The jumpers are shown in Figure 47.

Connecting an ISDN BRI S/T WIC to a Network


Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026



Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers. Statement 23


To connect an ISDN BRI S/T WIC to a network, 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 1-port ISDN BRI WIC with S/T interface, version 3 (WIC-1B-S/T-V3) only to intra-building or non-exposed wiring or cabling. 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-48C-to-RJ-48C cable to the RJ-48C port on the ISDN BRI S/T WIC.

Step 3 Connect the other end of the cable to the NT1 device, as shown in Figure 48.

Figure 48 Connecting an ISDN BRI S/T WIC to an NT1 Device

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.

Step 6 Check that the OK LED goes on, which indicates that the ISDN port has established a connection with the central office switch.

ISDN BRI U WICs Overview

The 1-port ISDN BRI U WICs contain an integrated NT1 device. This interface is also known as a U interface. There are three ISDN BRI U WICs:

Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 1-port ISDN BRI WIC with U interface, version 2 (WIC-1B-U-V2) 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.

Step 2 Connect one end of a straight-through RJ-48C-to-RJ-48C cable to the RJ-48C port on the ISDN BRI U WIC.

Step 3 Connect the other end of the cable directly to the ISDN wall jack as shown in Figure 53.

Step 4 Turn on power to the router.

Step 5 Check that the OK LED goes on, which indicates that the ISDN port has established a connection with the central office switch.
