Electromagnetic Compatibility Information
Classes
Various national agencies (in the United States, The Federal Communications Commission (FCC)) govern the levels of electromagnetic emissions from digital devices. Electromagnetic emissions can interfere with radio and television transmission. To reduce the risk of harmful interference these agencies have established requirements for manufacturers of digital devices
The manufacturer of a digital device must test and label a product to inform an end-user of the maximum emission level from the product when used in accordance with its instructions. The emission levels encountered are classified as Class A or Class B. A system that meets the Class A requirement can be marketed for use in an industrial or a commercial area. A system that meets the more stringent Class B requirement can be marketed for use in a residential area in addition to an industrial or a commercial area.
The end user is generally held responsible for ensuring that her system is suitable for its environment as stated in the above paragraph and bears the financial responsibility for correcting any harmful interference.
Modifications
Modifications or changes made to this device, and not approved by 3Com, may void the authority granted by the FCC, or other such agency, to operate this equipment.
Shielded Cables
Connections between 3Com equipment and other equipment and peripherals must be made using shielded cables in order to maintain compliance with FCC, and other agency, electromagnetic frequency emissions limits. This statement does not apply to the ISDN cable or 10BASE-T cables.
Federal Communications Commission Notice
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can create radio frequency energy and, if not installed and used inaccordance with the instruction manual, may cause harmful interference to radio communications. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
■Increase the separation between the equipment and the receiver.
■Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
■Consult the dealer or an experienced radio/TV technician for help.

22 CHAPTER 1: FEATURES AND SPECIFICATIONS
USING THE BRIDGE/ROUTER IN
2 YOUR NETWORK
|
This chapter gives an overview of SuperStack II NETBuilder SI |
|
bridge/routers and describes how they fit in your network. It also |
|
describes the software features of the bridge/router. |
|
|
Overview |
SuperStack II bridge/routers maintain connectivity among small, midsize, |
|
and large branch offices and the corporate LAN. |
|
SuperStack II NETBuilder SI bridge/routers come with two Ethernet ports, |
|
two or four serial ports, and one of the following WAN ports: ISDN S/T |
|
(models 43x and model 53x), ISDN U (models 44x and 54x), 56/64 Kbps |
|
Carrier Service Unit/Data Service Unit (CSU/DSU) (models 45x and 55x), or |
|
T1/FT1 Telco port (models 46x and 56x). You can change any model 4xx |
|
bridge/router to another model 4xx, or any model 5xx to another model |
|
5xx, by installing, removing, or replacing an interface module. |
|
All models can be upgraded to any software package. All models have |
|
dual-image software support for upgrading and backup. |
|
|
Using Ethernet LAN |
The SuperStack II NETBuilder SI bridge/router provides connection to two |
Ports |
Ethernet LANs using either 10BASE-T or 100BASE-TX Ethernet. Boundary |
|
router models have one port disabled. If you upgrade to full router |
|
software, the second port will be functional. |
Leaf node Boundary Routing® is not available on the model 5xx bridge/routers.
24 CHAPTER 2: USING THE BRIDGE/ROUTER IN YOUR NETWORK
Using WAN and SuperStack II NETBuilder SI bridge/routers come with two or four serial Serial Ports ports and one of the following WAN ports: a built-in ISDN S/T terminal
adapter (TA) (models 43x and 53x), a built-in ISDN U TA (models 44x and 54x), a built-in 56/64 Kbps CSU/DSU (models 45x and 55x) or a built-in T1/FT1 Telco port (models 46x and 56x).
ISDN Port (Model 43x, The ISDN port provides a basic rate interface (BRI). The BRI delivers two 53x, 44x and 54x) bearer (B) channels and one delta (D) channel. Each B channel can
transmit up to 64 kilobits per second (kbps); the D channel transmits information about the call to computers at the switching system at a rate of 16 kbps. You can use both B channels together for a combined data rate of 128 kbps, or use each 64 kbps B channel separately.
Some ISDN lines support up to 56 Kbps per B channel. For more information, contact your ISDN service provider.
Order ISDN lines from the phone company. See Appendix E for more information about ordering ISDN lines.
Installations in Hong Kong should be configured to originate and receive ISDN calls at 64 Kbps. Due to the variety of ISDN switches in the Hong Kong Telcom network, the SuperStack II NETBuilder SI bridge/router does not handle rate adapted ISDN calls at 56 Kbps properly.
56/64K CSU/DSU Port A CSU/DSU is equivalent to a modem for a digital line. The 56/64K (Model 45x CSU/DSU port connects directly to a Digital Data Service (DDS).
and 55x)
Order DDS lines from the phone company. Contact your phone company for more information about DDS lines and the services available for them.
T1/FT1 CSU/DSU Port A CSU/DSU is equivalent to a modem for a digital line. The T1/FT1 (Model 46x and 56x) CSU/DSU port connects directly to a T1 line or a fractional T1 line.
Fractional T1 consists of 24 channels (DS0s) at 64 Kbps each, so you can connect to one or more DS0s with the T1/FT1 port.
Order T1 lines from the phone company. Contact your phone company for more information about T1 lines and the services available for them.

serial devices. You can buy Flex-WAN cables separately from 3Com. See |
|
Appendix D for more information about Flex-WAN cables. |
|
If you are using two SuperStack II NETBuilder SI bridge/routers connected |
|
directly to each other by the serial ports (back-to-back), the |
|
bridge/routers do not meet radiated emissions specifications. |
|
For boundary routers, only one serial or WAN port can be active. The |
|
remaining ports are used for back-up only. |
|
|
Telco Services |
To create a WAN, you must buy lines and services from a |
|
telecommunications company (Telco). Services include dial-up lines, |
|
leased lines, and packet-switched services. |
|
Dial-up lines, like ISDN, allow you to dial your destination when necessary |
|
and hang up when you no longer need the connection. A leased line is |
|
always available between two locations. Dial-up and leased lines both use |
|
the Point-to-Point Protocol (PPP). |
|
Packet-switched services, like Frame Relay, use a combination of leased or |
|
dial-up lines with Telco-owned switching, which frees you from the cost |
|
of owning the line the entire length. |
|
Table 4 describes dial-up and leased line services available for the WAN |
|
and serial ports. Table 5 describes packet-switched services. |

All dial-up and leased lines use PPP. If you want to use multiple lines or channels to connect to the same destination, you can use Multilink PPP. Multilink PPP is especially useful for ISDN, as described in the following section.
ISDN ISDN consists of two bearer (B) channels and one delta (D) channel. Each B channel can transmit up to 64 Kbps; the D channel transmits signaling information about the call to computers at the switching system at a rate of 16 Kbps.
With Multilink PPP, you can use both B channels together for a combined data rate of 128 Kbps. With PPP, you can use each 64 Kbps B channel separately.
Some ISDN lines support up to 56 Kbps per B channel. For more information, contact your ISDN service provider.
You can use packet-switched services with your bridge/router instead of dial-up or leased lines to take advantage of high performance for a reasonable price. This section describes X.25 and Frame Relay.
X.25 An X.25 packet-switched network is defined by the International Telecommunications Union (ITU) Recommendation X.25, a global standard that began development in the 1970s. The recommendation
Telco Services 27
defines a point-to-point interaction between DTEs and DCEs. In simpler terms, when it is time to transmit data, a terminal connects to a modem or packet switch, which then connects to packet switching exchanges (PSEs) and other DCEs to transmit the data to its final destination at another terminal. The links by which data is transmitted are called virtual circuits. Virtual circuits allow data transfers between two points on the network through any number of nodes in the network.
Frame Relay Frame Relay provides a packet-switched network that transfers data between DTEs, which can be routers, bridges, and host computers, by creating virtual circuits and using DCEs to transfer the data to its destination.
Frame Relay differs from X.25 (which was developed to work over voice-grade telephone lines) because it was designed to make use of today’s higher speed digital lines. Frame Relay has also been designed to work within complex internetworking environments with extensions referred to as the local management interface (LMI).
LMI provides information about all devices that are accessible on the Frame Relay network by listing all data link connection identifiers (DLCIs) connecting the local system with the remote ones. The LMI improves reliability between the DTE and DCE through frequent exchange of keepalive packets that contain status information.
