System overview

Introduction

Meridian HomeOffice II provides telecommuters with a Meridian digital telephone, a fax port, and connection to their company’s Ethernet network over a single Basic Rate Interface (BRI) line to the telecommuter’s home office (the remote site). The BRI line terminates in an ISDN connection at a HomeOffice Router in the telecommuter’s home office. These communications links are illustrated on page 3.

Meridian HomeOffice II Line Card

The Meridian HomeOffice II Line Card (HLC) is a standard IPE line card designed to fit into IPE shelves a Meridian 1 or SL-100 switch located at the corporate office (the local site). Each HLC maintains up to 16 virtual telephones on 16 channels. Using the voice and data paths of each of these 16 channels, a single HLC manages up to 16 telecommuters’ home offices (remote sites).

The voice channels provide communications links between the digital telephones and the host PBX at the local site. The voice channels also provide the communications links between the digital telephone and the Remote Daughterboard (RDB) inside the HomeOffice Router at each remote site.

The data channels, which are normally idle in the Meridian telephone, provide the communications links between the HLC at the local site and the RDBs at remote sites.

Through the 16 virtual telephones, the HLC connects with up to 16 RDBs. Thus, the HLC manages up to 16 actual Meridian digital telephones at up to 16 remote sites. There is one port on the HLC for each HomeOffice Router it serves.

The PBX communicates with the HLC in the same way it does with an extended digital line card (XDLC). The HLC utilizes a dedicated, all-digital data channel to communicate with the HomeOffice Router through the RDB. The communications links of a Meridian HomeOffice II system are shown in the following illustration.

Features

Digital telephone emulation

By emulating HLC-compatible models of the Meridian digital telephone, the HLC allows telecommuters to function at their home offices as though they were at their corporate offices. HLC-compatible models of the Meridian digital telephone include the following models:

Meridian 2216

■

Meridian 2616

■

Meridian 2616CT (for firmware releases HLC 1.15 and later)

■

Meridian 3820

■

Variable security levels

Three security levels allow controlled access to HLC channels on a per-card basis. See “HLC security” on page 11 for further details. The following list describes these three levels:

Level 1: no call security

■

Access to the HLC’s channels is not restricted. Level 2: calling party ID (CPID)

■

The HLC identifies the number of the caller requesting access to one of its channels. If that number matches the remote number of the HomeOffice site configured for that channel, access is granted. If the number of the incoming call does not match, access is denied.

See “SET REMOTE (S R)” on page 131 for a discussion of this feature.

Level 3: security identifier

■

The HomeOffice Router sends the security identifier configured for the remote office from which the caller requests access. The HLC compares that number to the eight security identifiers configured for the HLC. When it finds a match, it grants access to that channel corresponding to that security identifier. (Security Level 3 is the default security level.)

See “Security level and security identifier” on page 17.

June 1999 Description

Online/Offline table

This table allows you to schedule times that the ISDN connection is made available to the HomeOffice II user, and times at which the telephone in the user’s home office reverts to normal telephone service.

Note:

This feature takes users online or offline on the specified day at the specified time. It does not prevent the user from accessing the Meridian HomeOffice II system.

See “SET ONOFFTABLE (S O)” on page 124.

Echo canceling

Echo canceling filters unwanted signals caused by echoes of the main signal. These unwanted signals often occur in long-delay communications, causing the speaker to hear an echo of his or her own speech in the receiver.

Firmware releases prior to HLC 1.15 supported echo canceling on any four HLC channels. HLC firmware releases 1.15 and above, shipped on AB-vintage and later HLCs, support echo canceling on all 16 HLC channels.

See “SET ECHO (S E)” on page 120.

Configurable password

You can change the HomeOffice II login password to control access to the HLC maintenance terminal.

Note:

The Host password

June 1999 Description

Physical architecture

Introduction

At the corporate office (local site), the HLC requires all-digital trunking through a T1, E1, or PRI link. The HLC is a digital line card designed to fit into a Meridian 1 or SL-100 IPE shelf or Option 11 cabinet. The HLC meets the electrical and bus interface requirements of this shelf. It has two serial ports: a Man-machine Interface (MMI), and a Serial Data Interface (SDI). You can daisy chain, or link, multiple HLCs through these ports, using one HomeOffice II Line Card Multi-I/O Cable per HLC, so that all HLCs in the daisy chain can share a single maintenance terminal. See page 28 for an illustration of a daisy-chained system.

Corporate office (local) site

At the telecommuter’s corporate office site, the HLC plugs into an IPE module or an Option 11 cabinet. The HomeOffice II Multi-I/O cable (see page 45) supplies MMI and SDI connections to the HLC, and links multiple HLCs in daisy-chained systems.

Home office (remote) site

At the telecommuter’s home office site, the all-digital line terminates into an ISDN connection at the HomeOffice Router. The HomeOffice Router supplies a MERIDIAN port (for connectivity to the digital telephone), the system’s Ethernet port, and an analog port (for an optional, user-supplied fax machine). The HomeOffice Router contains a Remote Daughterboard (RDB), which supplies the system with its digital telephone interface.

The HLC allows as much as 65 milliseconds (ms) of network delay between telecommuters’ corporate offices and their home offices. See page 3 for an illustration of the elements of the HomeOffice II system and their relationships to one another.

Functionality

Introduction

This topic summarizes the features provided by the HLC. Refer to Chapter 2 of this guide, “Hardware installation,” for step-by-step setup instructions.

Self-test

The HLC performs test functions to guarantee system integrity. The board completes a self-test each time it is turned on or reset. The faceplate LED blinks three times, then remains on until the switch enables the card, indicating a successful Self-Test.

If the LED blinks repeatedly at one-second intervals, try reseating the card at the switch by lifting the ejector tabs and pulling the HLC out. This breaks the connection between the card and the backplane. Then reinsert the card.

If the HLC still does not complete a successful Self-Test, see “Unsatisfactory Flash” on page 175 for instructions on how to revert the HLC to the factory default firmware load residing in the E-PROM module.

If the card still does not pass its Self-Test, it must be returned to the factory for service. See “Caution” on page 18.

User tests

You can choose from several available testing options. The HLC supports the following tests:

■

all switch tests supported by an XDLC See documentation for your specific switch for further details. a Connectivity Test to verify the connection between the HLC and the RDB

■

See “Connectivity test” on page 155. a Phone Test to verify signaling between the digital telephone and the RDB

■

See “Phone test” on page 156.

8 Meridian HomeOffice II

June 1999 Description

Circuit pack

The HLC conforms to the Common Features Specification for IPE line cards.

LED

The LED indicates card enabled/disabled status. The LED indicates a successful Self-Test by blinking three times each time you start or reset the card. If, after passing its self-test, the card’s LED remains lit, check the switch to see if the card is enabled. If the card is enabled and the LED remains lit, this indicates a problem at the switch.

Echo canceling

The Digital Signal Processor (DSP) provides echo canceling to all 16 channels of HLCs equipped with firmware load HLC 1.15 and later. Echo canceling isolates and filters unwanted signals, or echoes, from the main transmitted signal.

Echo is often experienced in long-delay communication when a person’s speech echoes in the receiver. A tail, in echo canceling terms, is the portion of your speech that returns to you in an echo. You usually measure tail length in milliseconds. (1000 ms = 1 second). See “SET ECHO (S E)” on page 120.

Note:

The particular routing of each call through the public switched telephone network (PSTN) can effect the need for echo canceling.

Multiple-agent (user) access

Each HLC has 16 channels (numbered 0–15). Each channel has access to only one ISDN connection. Multiple-agent functionality allows the you to assign up to eight different users (agents) to a single HLC channel. However, only one of these users (agents) can have access to the channel at any one time.

Line Card Configuration Guide 9

Description Draft 01.02

Through remote number configuration, see “SET REMOTE (S R)” on page 131, you can enable up to eight different users (agents) to access the same HLC channel with the understanding that only one agent can have access to the channel (and the channel’s ISDN connection) at any one time. Without multiple- agent access, the company must reserve an entire channel for each user (agent), even if the agent only uses the connection for part of the day.

Multiple-agent access allows several different people to use the same channel at different times during the same day. However, when a particular user (agent) attempts to go online, the channel must not be in use by another agent. If the channel is in use when an agent attempts to log in, the agent’s digital telephone will display an

“HLC Port Already in Use”

message. In other words,

the HLC supports only one ACD agent per channel online at any one time.

An example configuration for a single channel at a business that must have operators standing by around the clock to serve a global clientele is three individual agents, each assigned to one eight-hour shift.

You can assign a unique remote number and security identifier to each ACD agent. However, in a shift arrangement where each user works from the same telephone, this is not required.

Going online as an ACD agent

When an ACD agent attempts to go online, the HLC receives a data call from the agent’s HomeOffice Router requesting access to the appropriate channel.

If the channel is in use, the agent receives a message on the display of the

■

digital telephone stating “HLC Port Already in Use,” and is denied access to the HLC.

If the channel is not in use, the HLC checks the security ID sent by the

■

RDB in the agent’s HomeOffice Router against the security ID that you have configured for this agent number on this channel.

If the security IDs match, the agent is now active and can receive calls from the ACD queue.

10 Meridian HomeOffice II

June 1999 Description

ACD agents can also place calls in local mode (if authorized) while waiting for access to their channels. The agent who is active on a particular channel remains active until either the agent, the HLC (via the Online/Offline table), or the system administrator (via the

OFFLINE FORCE

command, see “OFFLINE FORCE (O F)” on page 146) places the channel offline. Agents who attempt to access an HLC channel in use by another user are denied access or receive a message on their display stating

“HLC Port Already in Use.”

HLC security

Security is provisioned on a per-HLC basis. For security validation, the HLC stores a database of eight Calling Party Identification numbers (compiled from the Remote numbers) and eight Security Identifiers per channel. There are three levels of security, as described below.

Security Level 3 (Security ID)

Security Level 3 is the default security level. When this level is provisioned, the incoming Security ID from an agent going online is compared with the eight provisioned IDs, and the appropriate ACD agent is activated. This ACD agent now receives calls from the ACD queue associated with this channel.

Security Level 2 (CPID)

When Security Level 2 is provisioned, the incoming calling party identification (CPID) for the call going online is compared against the eight CPID numbers, and the appropriate user or ACD agent is activated. Only this agent can receive and place calls until the channel goes offline.

Security Level 1 (no call security)

When provisioned for Security Level 1 (no call security), all incoming data calls are permitted, but new outgoing data calls are only initiated to the default (first available) user or ACD agent. This scenario can support multiple ACD agents per channel via permanent BRI connections initiated by the remote ACD agent.

CTI applications

First-party support

Meridian HomeOffice II Line Cards that are equipped with firmware releases

1.15 and RDB 9.2.8 and later provide full support for first-party Computer Telephony Integration (CTI) applications, such as Symposium FastView 1.6.0.3, Symposium Call Manager 5.0.32.29, and Desktop TAPI Server Provider

1.6.0.9c.

Some of these applications communicate to a Meridian Communications Adapter (MCA) installed in the base of the digital telephone or to the Symposium Communicator Card installed on the PC. While the MCA cannot place calls to other devices, it can support these first-party CTI applications.

Note:

First-party applications are computer applications that can provide a screen pop and on-screen telephone set control to the agent, and can route a telephone call.

Third-party support

Meridian HomeOffice II Line Cards that are equipped with firmware releases

1.15 and RDB 9.2.8 and later provide full support third-party Computer Telephony Integration (CTI) applications, such as Symposium TAPI Server Provider Release 2.1 for M1, and Symposium Agent 1.1.0.3.

Debug capability

HLCs equipped with firmware releases 1.15 and later allow troubleshooters to perform call traces, which trace the activity of the Meridian HomeOffice II system as it processes individual calls. The debug commands require special passwords. You can obtain these passwords from customer service technicians in troubleshooting situations only.

Note:

Only use the debug features of the Meridian HomeOffice II Line Card when instructed to do so by a customer service technician.

Description Draft 01.02

Extension cables

The HomeOffice II Multi-I/O cable may be unable to reach between the HLC and the MMI terminal or the SDI port on the switch. Because local site configuration varies, you may need the MMI extension cable and/or the SDI extension cable to supply connectivity between these elements of the HomeOffice II system.

You can purchase the extension cables from your Nortel Networks distributor. If you prefer to build the cables yourself, this guide provides the pin-out configuration for each. See “MMI extension cable” on page 47, and “SDI extension cable” on page 48 for detailed information on these cables.

Daisy chaining

If you require multiple HLCs at the corporate office, you can install them in a daisy chain to enable maintenance and configuration of all HLCs through a single maintenance terminal. For a detailed description of daisy chaining procedures and required daisy chain address DIP switch settings, see “Understanding the DIP switches” on page 33 and “Installing and cabling multiple HLCs” on page 53.

Card configuration: required elements

Introduction

Before you begin to use Meridian HomeOffice II, you must configure the following parameters for the HLC and the HomeOffice Router to be able to communicate with each other:

voice and data ports

■

remote number

■

security level and security identifier

■

Voice and data ports for each HLC channel

You must configure a voice and a data port for each HLC channel at the switch. This is basic to the operation of the HLC. The card will not function if these ports are not configured. See “Voice and data port configuration” on page 58.

Remote number

You must configure each channel’s HomeOffice ISDN number as its remote number. This allows for the transfer of voice and data information between the HLC and the Remote Daughterboard (RDB). For help configuring a channel’s remote number, see “SET REMOTE (S R)” on page 131.

16 Meridian HomeOffice II

June 1999 Description

Security level and security identifier

There are three security levels for controlling access to corporate ISDN connections. The default security level (Security Identifier verification, level 3) requires that you configure a security identifier (up to 10 digits) for a channel before the HLC allows access to that channel. For help on how to change to a different security level, see “SET CONFIG (S C)” on page 114.

If you choose not to change the HLC’s security level, you must configure security identifiers for each channel. For help on how to configure a security identifier, see “SET IDENTIFIER (S I)” on page 122.

Note:

You must configure a Security Identifier for each HomeOffice site served

by the HLC if you choose security level 3, the default security level.

For information on how to configure full HLC functionality, see “Optional HLC configuration” on page 84.

22 Meridian HomeOffice II

July 1999 Hardware installation

Preinstallation preparation

Introduction

To get the most out of your company’s investment in Meridian HomeOffice II, you must plan and prepare. This topic describes the preparation process.

Preinstallation preparation consists of

planning for the telecommuting needs of the company

■

preparing the site

■

unpacking and inspecting the equipment

■

taking inventory

■

Planning for the telecommuting needs of the company

Begin the installation plan by determining the number of telecommuters that your Meridian HomeOffice II system will support and, therefore, the number of HLCs you will need in your corporate office (local site) switch. The installation plan should include an outline of cable routing between the IPE shelf or Option 11 cabinet, the SDI port, and the MMI terminal at the corporate office.

The deployment plan should include the HLC configuration settings for each telecommuter. Data entry forms provided in the Meridian HomeOffice II Planning Guide (NTP 555-8321-101) facilitate planning.

Before MMI configuration can take place, you must configure PBX voice and data ports for each HLC channel. See “Configuring voice and data ports” on page 77 of this guide, and “Voice telephone configuration” and “Data telephone configuration,” in the Meridian HomeOffice II Planning Guide (NTP 555-8321-101).

Unpacking and inspecting the equipment

Unpack the equipment and inspect it for damage. When you unpack, follow these general precautions recommended by computer and telephone equipment manufacturers:

Remove items that generate static charge from the installation site.

■

Use antistatic spray if the site is carpeted.

■

Ground yourself before handling any equipment.

■

Remove the equipment carefully from its packaging.

■

Visually inspect the equipment for obvious faults or damage.

■

You must immediately report any damaged component to your sales representative and the carrier who delivered the equipment.

Hold any non-enclosed circuit cards by their non-conducting edges, and

■

keep them in their antistatic bags until you are ready for to install them. Do not stack the non-enclosed circuit cards on top of each other.

■

Taking inventory

After you unpack and visually inspect the equipment, and before you begin installation, verify that all the equipment is at the site. Check equipment received against the shipping documents. Report any shortages to your sales representative immediately.

Installation scenarios

Introduction

There are two types of general installation for a local site (corporate office) Meridian HomeOffice II system:

single-HLC

■

multiple-HLC (daisy chain)

■

Both of the above installations are outlined in the following pages.

Basic scenarios

Meridian HomeOffice II system installation can be categorized into three scenarios according to the number of HLCs at the site.

one HLC

■

two HLCs

■

more than two HLCs

■

Each of these scenarios require specific DIP switch settings and cabling patterns This topic concentrates on the needed cabling patterns. DIP switch settings are discussed in Section B: “Configuring the DIP switches,” on page 31.

Note:

NT8D37AA IPE cabinets utilize split-slot wiring. If you have one of these cabinets, your HLCs can only reside in slots 0, 4, 8, and 12 without rewiring the slot.

To use any other slot, you will need to rewire part of the IPE backplane using cable NT8D81AA (A0359946). Refer to the Meridian 1 System Installation and Maintenance Manual (NTP 553-3001-210) for details.

26 Meridian HomeOffice II

July 1999 Hardware installation

Installing a single-HLC

If your company has 16 or fewer telecommuters, a single Meridian HomeOffice II Line Card will provide HomeOffice II functionality to all of the current telecommuters. In this type installation, the single HLC provides connectivity to both the MMI and the SDI, each of which require specific cabling and DIP switch settings. The following illustration outlines the necessary cabling for this arrangement. For the unique DIP switch settings for a one-HLC system, see the table that lists DIP switch 1 (SW1) settings on page 34.

Hardware installation Standard 01.02

Installing multiple-HLCs

If your company has 17 or more telecommuters, your Meridian HomeOffice II system requires more than one HLC. Multiple HLCs can be daisy chained so that they can share one maintenance connection. Daisy chains with two HLCs require slightly different cabling from daisy chains with more than two HLCs. These differences are discussed in the following subsections.

Two HLCs

If there are two HLCs present in your switch, configure them in a daisy chain to allow both cards to share the same maintenance (MMI and SDI) connections. The card nearest the man-machine interface (MMI) terminal provides connectivity to the MMI, which allows for maintenance of the HLC. This card is the MMI end of the daisy chain.

The other card, the card nearest the switch’s serial data interface (SDI) port provides connectivity to the SDI, which allows for limited maintenance of the switch. This card is the SDI end of the daisy chain.

Each of these cards also requires a specific DIP switch setting. For more details, see “Setting the DIP switches for multiple HLCs” on page 37.

28 Meridian HomeOffice II

July 1999 Hardware installation

More than two HLCs

If there are three or more HLCs present in your switch, the information in the preceding paragraphs applies to the cards on either end of the daisy chain, the MMI end and the SDI end, for maintenance access. The cards that are not on either end are called intermediate cards. All intermediate cards are not directly connected to either the MMI or SDI and require different DIP switch settings from the cards on each end. For more details, see “Intermediate cards” on page

39.

Default settings

The default setting of all 16 DIP-switch positions on an HLC is OFF. This corresponds to a single HLC in a Meridian 1 switch with terminal settings of 9600 and N81 (no parity, eight data bits, and one stop bit).

DIP switch settings for HLCs in an SL-100 PBX

You must set position 4 of SW2 to ON if the HLC is in an SL-100 switch. See page 35 for a table that lists all DIP switch 2 (SW2) settings.

DIP switch 1 settings

If multiple HLCs are present, each HLC must have a unique address for the daisy chain to function properly. The first six positions on DIP switch 1 (SW1) define the unique daisy chain address of that HLC.

On the HLC whose HLC Multi-I/O cable is connected either to the MMI terminal or the MMI Extension cable, set SW1 position 7 to OFF. This HLC is at the MMI end.

On the HLC whose HLC Multi-I/O cable is connected to either the SDI port on the switch or the SDI Extension cable, set SW1 position 8 to OFF. This card is at the SDI end.

For every card not on either end of the daisy chain, positions 7 and 8 of SW1 must be ON. See “Intermediate cards” on page 39 for more information.

DIP switch 2 settings

DIP switch (SW2) position 1 selects the daisy chain’s baud, 9600 or 2400 bps. SW2 position 2 selects the daisy chain’s parity, number of data bits, and number of stop bits—the daisy chain’s terminal settings. SW2 position 3 selects the HLC’s firmware execution mode: allow FLASH or force E-PROM. SW2 position 4 designates the PBX as either a Meridian 1 or an SL-100 switch. SW2 positions 5–8 of are not used for release 4 of the HLC.

Setting the DIP switches for multiple HLCs

Introduction

If your system consists of more than one Meridian HomeOffice II Line Card, the cards must be set up in one of the two following configurations to be a functioning daisy chain:

a two-card configuration

■

a more than two-card configuration

■

For the daisy chain to function properly, each card must have a unique address, as set with positions 1–6. Also, one card in the daisy chain must be designated as the MMI end, using position 7, and one card must be designated as the SDI end, using position 8.

Two HLCs

In any HLC daisy chain, the first card, HLC 0, is located at the MMI end. That is, it provides connectivity to the MMI for all cards in its daisy chain. Plug 2 of HLC 0’s HLC Multi-I/O cable (see the illustration on page 45) connects either directly to the MMI, or to the MMI Extension cable. (See “MMI extension cable” on page 47.) DIP Switch 1, position 8, of HLC 0 must be set to ON.

The last card in any HLC daisy chain is located at the SDI end. That is, it provides connectivity to the SDI for all cards in its daisy chain. Plug 3 of its HLC Multi-I/O cable (see the illustration on page 45) connects either directly to the SDI, or to the SDI Extension cable. (See

48.) DIP Switch 1, position 7, of this HLC must be set to ON.

More than two HLCs

In an HLC daisy chain with more than two HLCs, the first card in the daisy chain, HLC 0, provides the MMI connection. That is, HLC 0 is located at the MMI end. Plug 2 of its HLC Multi-I/O cable (see the illustration on page 45) connects either directly to the MMI or to the MMI Extension cable. (See “MMI extension cable” on page 47.) SW1, position 7 of HLC 0, must be set to OFF. SW1, position 8 of HLC 0, must be set to ON.

In an HLC daisy chain with more than two HLCs, the last card in the daisy chain (HLC 2 in the illustration on page 29) is located at the SDI end. That is, it provides the SDI connection. Plug 3 of its HLC Multi-I/O cable (see the illustration on page 45) connects either directly to the SDI, or to the SDI Extension cable. (See “SDI extension cable” on page 48.) SW1, position 7, of this HLC must be set to ON. SW1, position 8, of this HLC must be set to OFF.

38 Meridian HomeOffice II

Intermediate cards

The difference between a two-HLC configuration and a more than two HLC configuration is the introduction of intermediate cards. An intermediate card is a card that is neither at the MMI end, nor at the SDI end. For example, in the three-HLC configuration illustrated on page 29, the middle HLC is the intermediate card. Its Multi-I/O cable is not on either end of the daisy chain and is not directly connected to the MMI or to the SDI.

All intermediate cards (cards not on the ends) must have SW1, both positions 7 and 8 set to ON.

SW1 settings for addressing multiple HLCs in a daisy chain configuration

Correct functioning of a daisy chain requires that each HLC have a unique address set via DIP switch. Position determines proper addressing in the daisy chain. The following table correlates the DIP switch settings of SW1, positions 1–6 to address numbers for a daisy chain of up to 32 HLCs.

Notes:

The following points pertain to addressing daisy-chained HLCs.

1. These settings define the binary address which, when converted to decimal,

DISPLAY

creates the HLC address. Therefore, when displayed using the

CONFIG (D C)

command (see “DISPLAY CONFIG (D C)” on page 102),

the settings will be shown in reverse, as in 6–1, instead of 1–6.

MMI terminal connection scenarios

Introduction

There are several methods of connecting an MMI terminal to a Meridian HomeOffice II Line Card for maintenance access. MMI terminal connection may be made via:

dumb terminal (or PC COM port)

■

terminal server on a LAN

■

modem

■

Dumb terminal or PC COM port

In order to connect an HLC to a dumb terminal, such as a PC COM port, to provide a man-machine interface (MMI) terminal for the system, attach the male 25-pin connector of the Meridian HomeOffice II Line Card Multi-I\O cable (Plug 2) to the female 25-pin connector of the dumb terminal (or PC COM port). This connection may require a 25-pin to 9-pin adapter.

If the HLC Multi-I/O cable is too short, attach Plug 2 of the HLC Multi-I/O cable to the female 25-pin connector of the MMI extension cable (see page 47). Then attach the male 25-pin connector of the MMI extension cable to the female connector of the dumb terminal. This connection may also require a 25-pin to 9pin adapter.

The maximum distance between the HLC and the dumb terminal is approximately 15 meters (50 feet). This allows approximately 0.5 meter (2 feet) for the HLC Multi-I/O cable and up to approximately 14.5 meters (48 feet) for the MMI extension cable.

Terminal server

To connect an HLC to a terminal server to provide a man-machine interface (MMI) terminal to the system, attach the male 25-pin connector of the Meridian HomeOffice II Line Card Multi-I\O cable (Plug 2) to a terminal server providing access to the corporate LAN. This connection requires a customer-supplied cable having the same pin-out as the MMI extension cable (see page 47), with a female 25-pin connector on one end, and the proper interface for connecting to the terminal server on the other end.

Line Card Configuration Guide 49

Hardware installation Standard 01.02

The maximum distance between the HLC and the terminal server is approximately 15 meters (50 feet). This allows approximately 0.5 meter (2 feet) for the HLC Multi-I/O cable and up to approximately 14.5 meters (48 feet) for the MMI extension cable.

Modem

To connect an HLC to a modem to provide a man-machine interface (MMI) terminal to the system, attach the male 25-pin connector of the Meridian HomeOffice II Line Card Multi-I\O cable, Plug 2, to the female 25-pin connector on the back of the modem.

To complete this connection, you need a customer-supplied cable having the same pin-out as the MMI extension cable (see page 47), a female 25-pin connector on one end, and the proper interface for connecting to the modem on the other end.

The maximum distance between the HLC and the modem is approximately 15 meters (50 feet). This allows approximately 0.5 meter (2 feet) for the HLC Multi-I/O cable and up to approximately 14.5 meters (48 feet) for the MMI extension cable.

Installing and cabling a single HLC

Introduction

Preparing the switch and actually placing the HLCs into their slots are identical procedures, no matter how many HLCs there are in your system. However, cabling is different for one-, two-, and more than two-HLC systems.

In all systems, the switch’s SDI connection is provided by either a 25-pin male SDI port or a cable kit with a 25-pin male connection. Establish your system’s SDI link by attaching P3 of the HomeOffice Line Card (HLC) Multi-I/O cable, or the female 25-pin connector of the SDI extension cable to the switch’s SDI connection.

For details on the potential methods of connecting to an MMI terminal, see “MMI terminal connection scenarios” on page 49.

This topic explains how to install and cable one HLC in a single-card system. Refer to the illustration on page 27 for help in making the proper connections. If you are installing multiple HLCs, see “Installing and cabling multiple HLCs” on page 53.

To prepare for installation

Configure the slot into which the HLC is to be inserted as if it were to hold

an extended digital line card (XDLC). Refer to the documentation specific to your switch for the exact procedures.

Set the DIP switches for the appropriate HLC configuration. See

“Understanding the DIP switches” on page 33.

Overview

Introduction

Trunk configuration involves arranging proper ISDN service between the local site’s Meridian 1 or SL-100 switch and the public switched telephone network (PSTN). You must tell your service provider the configuration parameters that should be configured on your system and the type of ISDN connection you need.

Primary Rate Interface (PRI)

■

Basic Rate Interface (BRI)

■

Note:

ISDN BRI trunk access is not supported in North America.

Host trunk configuration

Host trunk configuration for the Meridian HomeOffice II system requires telling your service provider the type of ISDN connection (PRI or BRI) you need and what parameters to configure. In some situations, under strict limitations, a T1/ E1 trunk may be used.

ISDN BRI configuration

ISDN BRI configuration, whether for host trunks or remote site connections, involves identifying the ISDN telephone numbers and the SPIDs assigned to each involved site. Your service provider will require a description of the ISDN service features (such as caller ID) that you want configured on your system.

62 Meridian HomeOffice II

July 1999 Software configuration

Host trunk configuration

Introduction

Recommended trunking option

ISDN PRI is the recommended trunking method for a Meridian HomeOffice II system.

ISDN PRI configuration

ISDN PRI trunks at the host site are used to transport calls between the host site and the public switched telephone network (PSTN). To ensure full functionality for all remote sites served by each HLC, verify with your service provider that the following elements are configured on each trunk:

two-way voice and two-way data capability

■

Caller ID (allows the security level for the HLC to be Level 2 - Caller ID)

■

end-to-end digital circuitry, no analog segments (check with both long-

■

distance and local service providers) non-blocking configuration (ensure that configuration will not block

■

HomeOffice II traffic)

T1/E1 DTI configuration

When the digital trunks used by the Meridian HomeOffice II system are T1 or E1, certain characteristics must be included for proper functionality of the system. Those features are included in the following list:

The connection must be digital end-to-end with no analog segments.

■

Line Card Configuration Guide 63

Software configuration Standard 01.02

The T1/E1 DTI connections from your service provider must be

■

provisioned as two-way DATA trunks only. The corporate PBX also must be configured with two-way DATA trunks.

■

The framing, encoding, signaling, and data rate on the PBX and CO must

■

be equivalent. The PBX configuration record must have the MODE set as TRK, with

■

trunk route settings as follows:

ISDN to NO

■

DSEL to DTA

■

NDEC/FEDC to EITHER

■

Note:

IBNT2 is an example of a DMS trunk with data capability.

ISDN BRI configuration

Some locations may require ISDN BRI service from the Meridian 1 or SL-100 switch (the host trunk connection) instead of PRI for geographical reasons. ISDN BRI configuration is identical to ISDN PRI configuration so, if your host trunk configuration must be BRI, the same configuration elements are needed to ensure full functionality for all remote sites served. Verify this with your service provider.

Note:

therefore, cannot be used as a trunking option.

In North America, ISDN BRI can only be ordered as a subscriber line and,

administer or support a Router at a telecommuter’s home office. ACD agents are connected to a PBX that does not provide ACD capability

■

For this scenario, the ISDN BRI line connects the ACD agents to the corporate PBX where the call center is located.

Configuration requirements

Ensure that the ISDN BRI service to the data network administrator’s desk is configured with the following items:

two B-channels providing both voice and data capability

■

Both B-channels must be Circuit Switched Voice and Data.

■

two directory numbers

Voice and data ports

The voice ports in a Meridian HomeOffice II system provide the communication paths at both the local and remote sites.

At the local site, communication between the switch and the HomeOffice II Line Card (HLC) travels a path provided by the voice port. At the remote site, communication between the Remote Daughterboard (RDB) in the HomeOffice Router and the Meridian digital telephone also travels a path provided by the voice port.

The data port in a Meridian HomeOffice II system provides the communication path between the HLC at the local site and the RDB at the remote site.

Communication paths in a Meridian HomeOffice II system

The illustration on the next page shows the functional relationships of voice and data communication paths in a HomeOffice II system.

The HLC port is actually the HLC channel mapped to specific voice and data ports (see “Configuring voice and data ports” on page 77.) The HLC port refers to the specific voice-and-data port pairing through which the assigned user (or in multiple-user or ACD environments, the logged-in user) accesses the corporate switch.

Configuring voice and data ports

Introduction

This topic discusses essential voice and data port configuration. For Meridian HomeOffice II to function properly, you must configure voice and data ports for each channel on the HLC. This configuration takes place at the switch.

Port mapping

The following table shows the correct mapping between voice and data ports and HLC channels on both Meridian 1 and SL-100 switches.

14 14 30 28 29

15 15 31 30 31

As shown in the preceding table, the first channel configured for a Meridian 1 switch is channel 0. With channel 0, the corresponding voice port is port 0 and the corresponding data port is port 16.

The first channel on an SL-100 switch is also channel 0 and the corresponding voice port is port 0; with channel 0 of an SL-100 switch, the corresponding data port is port 1.

Voice port configuration

On a Meridian 1 switch, configure the voice port as a Meridian 3820 or 2616CT digital telephone with all the features (such as voice mail, call transfer, and so on) that are configured on the telecommuter’s local site telephone.

On an SL-100 switch, refer to switch documentation for the actual parameter if you are using a cordless telephone.

Data port configuration

Configure the data port as an MCA data adapter with the first line able to make and receive data calls. To configure the data port as an MCA adapter, make the following settings in LD 11:

Meridian 1 software release Setting

15 - 17 CLS prompt = DTA

18 and above DTA0 prompt = MCA

For further details, refer to the section on LD 11 in the Meridian 1 X11 I/O Guide (NTP 553-3001-400).

How the voice and data ports work together

If a phone call is placed to voice port 0 on a completed system, the HLC places a call to the RDB over the associated data port. (Confirm that the data port is configured to place calls.) If the HLC status is then queried from the SDI port, HLC ports 0 and 16 on a Meridian 1 system (ports 0 and 1 on an SL-100 system) appear busy.

Online/Local Calling key

For the voice and data ports on the Meridian HomeOffice II Line Card to function together, you must properly configure the Online/Local Calling (Online/LC) key.

The Online/LC key toggles the Meridian digital telephone on and off the ISDN connection at the corporate switch. This key turns the Meridian HomeOffice II system on and off, allowing telecommuters’ telephones in the local calling mode to operate as normal telephones in the public switched telephone network (PSTN).

Proper operation requires a feature key to be reserved for the Online/LC function at the switch. To do this, simply leave the key blank. Any feature programmed on this key at the switch is overridden and lost when the key is programmed as the Online/LC key via Local Manager at the remote site.

Refer to documentation for your specific switch for details on the proper procedure for configuration.

To configure voice and data ports

Because this is a switch configuration procedure, the exact procedures will be contained in documentation for your particular switch. The first step in port configuration on any switch, however, is accessing the Host SDI connection.

Note:

The HLCs should be in their card slots while completing voice and data

port configuration.

If you are not already logged in to the system, log in to the MMI. See

“LOGIN (L)” on page 91.

Result:

Enter the HOST command to access the SDI connection. See “HOST
