This chapter provides an overview of the Visitor and Community Network Access Concentrator (VCN AC), its operation and advantages.

This chapter includes the following topics:

■ Visitor and Community Network System Major Features and Benefits

■ Applications

■ VCN AC Features

Visitor and Community Network System Major Features and Benefits

Features

A Visitor and Community Network (VCN) system consists of a VCN Access Concentrator (VCN AC) and up to 24 VCN Access Points (VCN AP) connected by conventional 4-wire telephone cables.

The following are the major features of the Visitor and Community Network System:

The Visitor and Community Network System works over existing

■

cabling infrastructure and supports all Plain Old Telephone Services (POTS) while simultaneously providing Ethernet connectivity at speeds up to 10 Mbps full duplex.

The Visitor and Community Network System geographic range is four

■

kilo feet from an VCN AP to an VCN AC over Category 1 to Category 5 cabling.

The system supports Ethernet 802.1Q frames transparently.

■

The customer can simultaneously engage in two analog toll quality

■

conversations while sending high speed digital data on the POTS cable.

10 O

VERVIEW

The system provides fast Internet connectivity and fast corporate

■

access to end-users.

Benefits

The Visitor and Community Network System provides the following benefits:

Existing wiring is used for simultaneous voice calls and data

■

connections. During installation, re-wiring is not required and business operations continue normally.

The system enables a customer to use a telephone extension to place calls while sending and receiving digital data over the same cable. A second extension over the same telephone cable can be used to place another call, send faxes, or connect an analog modem.

The customer receives Internet services more conveniently at faster speeds. Hotel guests traveling on business can access corporate Intranets and use e-mail over much more convenient connections than is currently possible.

The system permits a hotel to provide new data communication services without forfeiting any POTS revenues.

The system’s ready-to-use, out-of-the-box, room-by-room installation

■

provides easy and cost-effective setup in an existing facility’s telecom wiring closet or private branch exchange (PBX) room. Its non-disruptive installation prevents complete hotel or floor shut downs.

The system is totally manageable from the user VCN AP to the VCN

■

AC. Management software provides a real-time view of system status with troubleshooting tools. Both the VCN AP and VCN AC support local management through a terminal emulating computer connection. In the VCN AC, all port cards can be centrally managed from the first card. The VCN AC supports secure remote management through a Telnet connection in the Internet or Intranet. A single VCN AP can be used to remotely download software to a VCN AC attached to an Ethernet switch and to the APs attached to the VCN AC.

The system facilitates low cost of ownership through the re-use of

■

common cabling systems, such as Category 5. The system presents a low cost solution while providing customers with mutiple services over a single wire, and providing operators of hotels, residential telecommunications, and office towers a single manageable network. It offers low cost maintenance and flexible tracking capabilities and is

Applications 11

readily integrated with existing hotel and multiple dwelling unit (MDU) billing systems.

The system is easily expanded to cover the required number of rooms.

■ The Visitor and Community Network System provides a foundation for

future services such as IP telephony. The system offers the capability to present local advertising and local interest information from a Visitor and Community Network (VCN) server to users on their computer monitors. Via a VCN server, Internet, video on demand, and gaming services can be billed.

Applications

The Visitor and Community Network System serves the following applications:

■ Multiple Dwelling Units (MDU)

MDUs include apartment houses and hotels.

■ Multiple Tenant Units (MTU)

MTUs comprise mainly office complexes.

The VCN AC is connected to the VCN APs, the analog PBX, and an Ethernet switch, e.g. a 3Com VCN Services Switch or a SuperStack II Switch 1100. A standard metallic pair telephone line connects each VCN AP to a VCN AC co-located with the analog PBX or local telephone exchange.

The Visitor and Community Network solution also works with the SuperStack II Switch 3300.

When a personal computer equipped with an Ethernet card is plugged into the Ethernet port of the VCN AP, the Visitor and Community Network system provides fast internet and other network services for data transmissions, and allows voice channels to be used simultaneously.

VCN AC Features 13

A person can speak on the telephone attached to the VCN AP and simultaneously send data from his computer. A telephone extension based on the same cable as the first telephone can be used at the same time as the first telephone. The telephone extension does not share the same wire pair as the computer and does not pass through the VCN AC.

Thus a hotel or a residence that installs a Visitor and Community Network System becomes able to add many more communications services without losing any existing capability.

The VCN AC separates voice and data channels upstream and joins voice and data channels downstream toward the end user for all VCN APs it services.

The Visitor and Community Network System facilitates intra-campus data communications over a high speed Local Area Network (LAN), i.e., Intranet. If the campus is connected to an ISP, the system enables the users on the campus to use the Internet.

Existing LAN infrastructure can be extended to locations currently lacking LAN cabling through the Visitor and Community Network System.

VCN AC Features

Services that do not need the LAN, for example, voice and fax, continue to operate normally.

The main VCN AC feature is to combine data and analog voice in the direction of the VCN APs and to split voice and data in the direction from the VCN APs (see Figure 2

). Analog voice (telephone) is routed to the analog PBX. Data is transferred to the Ethernet switch. The VCN AC allows simultaneous transfer of voice and data of up to 10 Mbps full duplex on each telephone extension line.

Local Management

The VCN AC enables local management of every communication port.

Figure 5

shows the VCN AC front panel with the Local Management Access (LMA) ports uncovered. For every VCN AC communication port there is an LMA port. The LMA ports are for connecting ASCII terminals that provide the management interface. The user monitors and manages each communication card through a management terminal directly attached to the card LMA port. Line status information on the VCN AP-VCN AC connection is available.

Central Management

Central management of all VCN AC ports is performed through LMA port 1 (the leftmost LMA of the VCN AC) or Telnet. The user sends commands to the management agent in card slot 1 through a locally attached management terminal or remotely through a Telnet session. The management agent controls the communications ports by sending them commands and receiving responses through a proprietary management message set. The user monitors and manages the VCN AC from a single point and can view status and statistical information on the VCN AP-VCN AC lines as well as perform certain configurational options such as setting full or half duplex.

LMA port 24

Remote Management

An VCN AC can be centrally and remotely managed via Telnet. Instead of attaching a terminal to the LMA, the user connects to the VCN AC management agent (in the leftmost card slot) though the Telnet protocol over the Internet. Access is password protected. Messages in the management user interface are carried in the VCN AC card slot 1 LAN port, which is connected by an Ethernet link to an Ethernet switch. It is not neccesary for LMA port 1 to be used.

Connecting Cables to

the Rack Without a

Patch Panel

Note the following:

The card in VCN AC slot 1 provides central management and is different from the remaining cards. This card has a factory installed MAC address and must not be inserted in any slot other than slot 1.

This section describes how to connect the rack without a patch panel. The VCN AC connects directly to the VCN AP and PBX punch-down blocks at the back with RJ-21 connectors.

Back Panel Connections

Perform the following steps to connect the VCN AC to the punch-down blocks.

Connect one RJ-21 flat cable to the VCN AP punch-down block through

the RJ-21 connector labeled “FROM VCN AP”. Connect the other RJ-21 flat cable to the PBX punch-down block through

the RJ-21 connector labeled “TO PBX”.

To connect the back panel of the VCN AC, use the 2 flat cables with RJ-21 connectors supplied with the VCN AC.

The pin assignments of the two RJ-21 connectors at the back of the VCN AC must match the pin assignments of the RJ-21 connectors of the two punch-down blocks.

For instructions on mounting and powering-up the SuperStack II Switch 1100, see the

SuperStack II Switch 1100/3300 User Guide.

If your switch is not a SuperStack II 1100 or 3300, follow the procedures for your switch.

This section describes the procedure for configuring the Ethernet switch.

Sequence of Configuration

The following is the sequence of configuration actions: Define the desired VLANs, if any, on your switch.

Define the MAC addresses for all of the 24 VCN AC ports and all APs

attached to the AC. Connect the VCN AC.

Defining the VLANs after the VCN AC and AP MAC addresses may make some of the addresses inaccessible.

The default VCN AC VLAN for management is VLAN 1 tagged.

If MAC addresses are not defined before the VCN AC is connected, the switch will flood the entire network with the initial messages sent through the VCN AC, since the destination addresses are unknown.

Not more than one VCN AC may be connected to a switch.

The remainder of this section describes the procedure for defining MAC addresses for the VCN AC and VCN APs.

Inserting MAC Addresses for VCN Access Concentrator Ports

Detailed instructions are presented here for both manual and automated procedures for the SuperStack II 1100 and 3300 Ethernet switches.

General guidance is provided for non-SuperStack switches.

Installing the VCN Access Concentrator 37

Procedures for a non-SuperStack Switch Automated procedures for non-SuperStack switches are not available. For a non-SuperStack switch, the Manual Procedures for SuperStack II 1100/3300

serve as a general outline for manual MAC address insertion, but the user follows the detailed instructions in the non-SuperStack switch user guide. Implement the MAC addresses listed in Ta b l e 7

for the VCN AC. Repeat the procedure to define the MAC addresses of the 24 VCN APs attached to the VCN AC. Start with the lowest VCN AP MAC address of 00-C0-DA-40-80-19 and assign addresses for up to 24 VCN APs consecutively.

Manual Procedures for SuperStack II 1100/3300 Enter every one of the 24 VCN AC port MAC addresses through the SuperStack II web management interface.

Refer to the SuperStack® II Switch Management Guide, and follow the instructions in the section “Inserting Permanent Entries” for the Switch Database dialog. You will need to use a web browser on the computer connected to the switch.

Line Card Menu Hierarchy and Summary

This section provides a menu hierarchy to describe the structure of the menu system and a menu summary to help the network administrator use the management system efficiently.

The chart in Figure 28

summarizes the menu hierarchy. The abbreviations next to the menu names are suggestions for how the menus are used. Most of the menus labeled D are not described further in this chapter since they are used mainly by developers for debugging. The debug menus for performing loopbacks are described since loopbacks can be used by network administrators in problem solving.

Central Management

Overview

This section describes central management.

The management agent in the card, in VCN AC slot 1, performs central management of the VCN AC through a proprietary protocol. The management agent supports monitoring and control of all 24 VCN AC ports.

Queries and

Control M essages

Starting with hardware release 2.0, management messages between card 1 and the other 23 VCN AC cards are carried over an internal serial link. Central management message flow is displayed in Figure 56

. The internal

serial link is not shown in the figure.

In previous releases, management messages between card 1 and the other 23 VCN AC cards are carried over the Ethernet through the Ethernet switch to which the VCN AC is connected. The flows in

Figure 56

pass through the Ethernet switch to which the VCN AC is connected. The Ethernet links used by management messages are not shown in the figure.

There are two user interfaces for central management:

A terminal emulating computer attached to the LMA port in VCN AC

■

slot1 A Telnet session between a management computer and the VCN AC

■

The user commands cause the Management Agent in VCN AC slot 1 to issue queries and control messages to all the cards in the VCN AC. The

Central Management 81

management receives status and statistics messages from the cards in the VCN AC and displays responses to the user commands on the user’s screen.

In LMA access, the user’s computer is directly attached through the VCN AC LMA port (Figure 57
