CautionTo comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the HWIC-4B-S/T interface cards only to intra-building or unexposed wiring or cable that is shielded and grounded at both ends. 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.

The HWIC-4B-S/T connects to an ISDN WAN network through an external Network Termination 1 (NT1) device. This interface is also known as an S/T interface

Accessibility  HWIC-4B S-T思科原装线卡模块

These HWIC-4B S-T思科原装线卡模块can be configured using the Cisco command-line interface (CLI). The CLI conforms to code 508 because it is text based and it relies on a keyboard for navigation. All functions of the router can be configured and monitored through the CLI.

Platform Support for HWIC-4B S-T思科原装线卡模块 

The HWIC-4B-S/T is supported on the following Cisco router platforms:

•Cisco 1841 Integrated Services Router (ISR)

•Cisco 2801 ISR

•Cisco 2811 ISR

•Cisco 2821 ISR

•Cisco 2851 ISR

•Cisco 3825 ISR

•Cisco 3845 ISR

HWIC-4B S-T思科原装线卡模块

The HWIC-4B-S/T has two LEDs associated to an interface. These LEDs are located in the top corners of each port. These LEDs indicate call activity on the two ISDN BRI B channels

Prerequisites for Connecting ISDN BRI S/T High-Speed WAN Interface Cards to a Network HWIC-4B S-T思科原装线卡模块

Before connecting an HWIC to the network, ensure that the HWIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the HWIC to the network. This section describes the preparation necessary before connecting an HWIC-4B-S/T to the network.

WarningThe 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

Use a straight-through RJ-45-to-RJ-45 cable (not included) to connect an ISDN BRI S/T HWIC to a network.

WarningHazardous 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

Connecting an HWIC-4B-S/T to a Network  HWIC-4B S-T思科原装线卡模块

To connect an HWIC-4B-S/T card to a network (NT1), use a straight-through RJ-45-to-RJ-45 cable.  These ports are color-coded orange.

Figure 2 Connecting an HWIC-4B-S/T to an NT1 Device

CautionThe router should be turned off before performing tasks to connect the HWIC-4B-S/T to a network.

To connect an HWIC-4B-S/T to a network, follow these steps:

Step 1Connect one end of a straight-through RJ-45-to-RJ-45 cable to the RJ-45 port on the HWIC-4B-S/T.

Step 2Connect one end of the cable to the external termination resistor (100ohm).

Step 3Connect the other end of the cable to the NT1 device

Step 4Follow the instructions in the documentation that came with the NT1 device to connect the NT1 device to the ISDN wall jack.

Step 5Turn on power to the router.

Connecting Point to Multipoint HWIC-4B S-T思科原装线卡模块

To connect one or more basic ISDN ports, use the ISDN BRI interface to connect the point-to-multipoint S interface.

NoteThe resistor is added to the bus at the furthest point from the NT1.

NotePoint to multipoint support is permitted only when no bus loop power is consumed by any endpoint on the bus. The HWIC-4B-S/T does not consume S-bus loop power.

Step 1Connect one end of a straight-through RJ-45-to-RJ-45 cable to the RJ-45 port on the HWIC-4B-S/T.

Step 2Connect the other end of the RJ-45 cable to up to 7 other Traffic Engineering (TE) interfaces and external terminating resistor.

Upgrading ISDN BRI Network Modules HWIC-4B S-T思科原装线卡模块

To upgrade your existing HWIC-4B-S/T on the Cisco 2800 or Cisco 3800 ISRs, see the replacement HWICs listed in HWIC-4B S-T思科原装线卡模块

NoteSame-slot replacement of the network module with the HWIC-4B-S/T is not possible unless the slot supports HWICs.
