PREFACE

The Octel Communications XC1000 multiple-applications platform provides
telephone answering and voice processing to the customer -premise equipment
(CPE) marketplace. This manual provides procedures for installing,
maintaining, and troubleshooting the XC1000. The manual also provides a
status-code explanation, component-replacement procedures, upgrade
procedures, system utilities, and a component description.

The XC1000 Service Manual was designed in a task-oriented format for
installers and service personnel. The manual supports XC1000s through
Release 4.0. It is organized into eight major parts: Installation, Mainte­nance, Auxiliary Information, Upgrades, Addenda, Appendixes, Glossary,
and Index. The first four parts comprise chapters that detail procedures
for specific functions. The last four parts include supplementary informa­tion. As needed, each part or chapter can be removed and used separately
by the installer and service personnel.

Chapters are numbered sequentially throughout the manual. Each chapter
includes a detailed table of contents. A general table of contents is
included at the beginning of the manual. The glossary provides definitions
of terms that might not be familiar to the service engineer. An index at the
back of the manual allows information about specific subjects to be located
rapidly and easily.

FCC PART 15 STATEMENT

WARNING: This equipment generates, uses, and can radiate radio frequency
(RF) energy and, if not installed and used in accordance with the instruction
manual, could cause interference to radio communications. It has been tested
and found to comply with the limits for a Class A computing device pursuant
to Part 15 of the FCC Rules, which are designed to provide reasonable
protection against such interference when operated in a commercial environ­ment. Operation of this equipment in a residential area is likely to cause
interference, in which case the user, at his own expense, would be required to
take whatever measures are necessary to correct the interference. Any
changes or modifications to this product not expressly approved by Octel
Communications could void the warranty or maintenance agreement.

CANADIAN DEPARTMENT OF COMMUNICATIONS
STATEMENT

This product does not exceed the Class A limits for radio noise emissions
from digital apparatus set out in the Radio Interference Regulation of the
Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruite radioélectriques
dépassant les limites applicables aux appareils numériques de la class A
prescrites dans le Règlement sur le brouillage radioélectrique édicté par le
ministère des Communications du Canada.

FCC PART 68 STATEMENT

This equipment complies with Part 68 of the FCC rules. On the rear of
this equipment is a label that contains the FCC registration number and
ringer equivalence number (REN) for this equipment. If requested, this
information must be provided to the telephone company.

Your XC1000 multiple-applications platform is designed to be used on
standard-device telephone lines. XC1000 is connected to a telephone line
by means of a standard jack. Connection to telephone-company-provided
coin service (central-office-implemented systems) is prohibited by the FCC.
Connection to party-line service is subject to state tariffs.

Telephone Company Procedures

The goal of the telephone company is to provide you with the best service
possible. To do this, it is occasionally necessary for them to make changes
in their equipment, operations, or procedures. If these changes might
affect your service or the operation of your equipment, the telephone
company will give you notice, in writing, to allow you to make any changes
necessary to maintain uninterrupted service.

vEdition OneXC1000 Service

COMPLIANCE STA TEMENTSXC1000 SERVICE

If you have any questions about your telephone line, such as how many
pieces of equipment you can connect to it, the telephone company will
provide this information upon request.

In certain circumstances, it could be necessary for the telephone company
to request information from you concerning the equipment that you have
connected to your telephone line. Upon request of the telephone company,
provide the FCC registration number and the ringer equivalence number
(REN) of the equipment connected to your line; both of these items are
listed on the equipment label. The total of all the RENs on your telephone
lines should be less than five to ensure proper service from the telephone
company. In some cases, a total of five is not usable on a given line.

If Problems Arise

If any telephone equipment is not operating properly, you should immedi­ately remove it from your telephone line, as it could cause harm to the
telephone network. If the telephone company notes a problem, they can
temporarily discontinue service.

When practical, they will notify you in advance of this disconnection. If
advance notice is not feasible, you will be notified as soon as possible.
When you are notified, you will be given the opportunity to correct the
problem and informed of your right to file a complaint with the FCC.

In the event that repairs are needed on your XC1000, they should be per­formed by Octel Communications Corporation or an authorized representative
of Octel Communications Corporation or the warranty or service agreement
could be void. Call your local Octel representative. Octel personnel are
available at response centers in the United States and Canada. The telephone

INTRODUCTION

1.1 OVERVIEW

This XC1000 Service Manual provides infor mation about the Octel XC1000t
multiple-applications platform for use by service personnel who install, main­tain, or troubleshoot the system. The manual is divided into eight sections:

Section I: Installation Addenda
Section II: Maintenance Appendixes
Section III: Auxiliary Information Glossary
Section IV: Upgrades Index

The first four sections are further divided into chapters, which are numbered
sequentially throughout the manual. Each chapter includes a detailed table of
contents; a general table of contents is included at the beginning of the manual.
The manual was designed for hands-on use; each section can be removed for
use by installers or maintenance personnel. An index is located at the back of
the manual.

1.2 DESCRIPTION

The Octel XC1000 multiple-applications platform provides voice-processing
functions for a variety of private-branch exchanges (PBX) or central offices
(CO). XC1000 provides three basic functions:

- Telephone answering. If a mailbox subscriber is not available to

answer a telephone call, the switch can forward the call to the
subscriber’s mailbox on XC1000. The caller can then leave a voice
message for the subscriber.

- Voice messaging. XC1000 subscribers can send messages to other

XC1000 subscribers without being in direct contact with them. In a
single session in their XC1000 mailboxes, subscribers can send
messages, listen to messages sent by a caller or subscriber, reply to
messages, and send copies of messages to other subscribers.

- Call processing. XC1000 provides call-processing methods that

include the following:

- Automated attendant

- Information Centertmailboxes (ICMBs)

- EnhancedtCall Processing (ECP)

The automated attendant answers calls to the switch and routes
callers to the desired telephone number. Incoming calls are handled
more efficiently and the workload of telephone company operators,
attendants, or answering centers is reduced.

XC1000 can store recorded messages or announcements in special
ICMBs, which can be heard by anyone calling that ICMB.

The ECP feature allows callers to select from up to nine menu choices
and be routed to another destination.

SECTION 1.2

This manual supports XC1000s using software through Release 1.5.
XC1000 can be integrated with up to 16 switches and can support up to
seven system manager/service terminals. Each XC1000 can provide up to
30,000 mailboxes. (XC1000s with software releases earlier than Release 1.2
provide 15,000 mailboxes.)

1.2.1 Hardware

The major components of XC1000 are the logic cards, disk drives, power
supplies, and system-interconnection hardware. The logic cards include the
central processing unit (CPU), a monitor card, system and message file
cards, telephone interface cards (TICs), either digital line cards (DLCs) or
fax-capable universal DLCs (UDLCs), and an optional asynchronous
communications processor (ACP) card. These components are described in
Chapters Ten and Twelve.

XC1000 is available in three configurations:

- The Single Cabinet, Nonredundant configuration includes one CPU,

one system file card, one message file card, and one optional ACP card,
as shown in cabinet 1 of Figure 1-1. The cabinet contains six TIC slots
and six DLC slots, allowing up to three line-card groups (composed of
TICs and DLCs), for a total of 72* ports, and a +5-Vdc and +12-Vdc
power supply. The XC1000 can also contain another +5-Vdc and +12-Vdc
power supply to configure the system with redundant power -supply pairs.
If one power supply fails, the second can provide the full load.

INTRODUCTION

- The Dual Cabinet, Nonredundant configuration includes one CPU,

one system file card, one message file card, and one optional ACP card
(Figure 1-1, cabinets 1 and 2). The two cabinets together have 12 TIC
slots and 12 DLC slots, allowing up to six line-card groups (composed
of TICs and DLCs), for a total of 144* ports, and two redundant
+5-Vdc and two redundant +12-Vdc power-supply pairs. If one power
supply fails, the second in the pair can provide the full load.

- The Dual Cabinet, Redundant configuration includes two CPUs, two

system file cards, two message file cards, and one optional ACP card.
One card of each pair, designated A, runs the system. If the A card
fails, the B card assumes control following an automatic system
reboot. The two cabinets together have 12 TIC slots and 12 DLC slots,
allowing up to six line-card groups (composed of TICs and DLCs), for a
total of 144* ports, and two redundant +5-Vdc and two redundant
+12-Vdc power-supply pairs. If one power supply fails, the second in
the pair can provide the full load.

Figure 1-2 shows the interaction among XC1000 logic cards and drives.
Each logic card has card-status LEDs on the front edge of the card; other
LEDs on the front edge have varying functions, depending on the type of
card. XC1000’s power includes –48-Vdc input-power terminals and the
+12- and +5-Vdc power supplies. Six cooling fans per cabinet help to
maintain a constant temperature within each cabinet.

* The European digital version supplies a maximum of 120 ports, 90 ports in cabinet 1 and 30

ports in cabinet 2.

CABINET 1 CABINET 2

Figure 1-1. Dual-Cabinet, Nonredundant.

The main backplane connects logic cards to the system data and control
buses, distributes power to all cards, and provides the interface between
trunks and TICs. The main backplane also provides the pulse-code-modulation
(PCM) bus that allows communications between TICs and DLCs.

The disk backplanes in cabinet 1 allow the file cards to communicate with
the system and message drives. Each XC1000 platform contains three disk
backplanes, one for the system-drive shelf and two for the message-drive
shelves. The disk backplanes provide power and signal connections between
the file cards and the drives on each shelf.

TICS, DLCs, and power supplies are hot-pluggable; that is, they can be
removed and reinstalled without taking the XC1000 out of service. However,
the cards must be disabled in menu 13.11. The hot-plug TICs and DLCs
apply to all XC1000s at software Release 1.5 or newer. Hot-plug power
supplies are a standard feature on all XC1000s shipped since June 1992
and must be installed if the XC1000 is upgraded to Release 1.5.

XC1000 has an RS-232 serial data port on the main distribution board for
the primary system manager terminal (SMT). Status messages at initial
power on, during system boot, and during normal operation are displayed
on the primary SMT. This SMT should be used to perform disk-drive
utilities for maintenance tasks. The primary SMT is normally located close
to the XC1000 cabinet and connected to this port. An optional printer can
be attached to the SMT.

1.2.2 Software

The operating software is permanently stored on system drives 0 and 1 (S0
and S1) and uploaded to the CPU random-access memory (RAM) during the
boot process. The hard-disk-based software includes the following major
components:

- Operating system

- Application code

- System management menus

- Phrase tables and phrases

- Initial program load (IPL)

- Site-specific database

System drives 0 and 1 each contain a copy of the operating program. During
the IPL sequence, the CPU reads the operating program from drive S0.
During normal operation, data is written to both drives. XC1000 retrieves
data from the least-busy drive, which reduces drive-access delay time.

INTRODUCTION

1.2.3 Switch Integrations

XC1000 supports four types of integration: (1) RS-232 integrations, which use
separate simplified message desk interface (SMDI) data links to the main
distribution board or to the asynchronous communications processor (ACP),
if equipped; (2) in-band integrations, which use ATIC or E&M tie lines or T1
trunks (the ATIC can be used “dry circuit” for some integrations); (3) ad­vanced, R2 in-band integrations, over a digital transmission facility that
multiplexes several channels onto a single transmission medium and supports
up to 30 DLC voice channels; or (4) common channel signaling/signaling
system 7 (CCS/SS7) integrations.

When the switch is integrated with the XC1000, callers are forwarded
directly to the subscriber’s personal greeting when the subscriber’s
telephone number is busy or does not answer. If the switch is not
integrated with the XC1000, the switch and XC1000 must be interfaced.
That is, when a call is made to a telephone number that is busy or does
not answer, XC1000 answers the call and the caller must reenter the
subscriber’s number at the XC1000 main greeting.

SECTION 1.2

1.2.3.1 RS-232 Integrations. XC1000 supports two data-link configurations,

providing terminations for three separate SMDI data links in a standard
configuration or up to 16 data links with the optional ACP. The switch
transmits the subscriber’s telephone number to XC1000 through a data
link when the switch forwards a call to XC1000. XC1000 matches the call
at the port with the called subscriber’s number, prompts the caller to leave
a message, and stores the caller’s message in the subscriber’s mailbox.
XC1000 returns a data message to the switch through the data link for the
switch to turn on the message-waiting indicator on the subscriber’s
telephone.

Each data link connects to a 25-pin RS-232 connector located on the main
distribution board or ACP I/O distribution board, if equipped, at the rear of
cabinet 1. The data link connects directly to an ACP card that controls the
operation of the data link.

1.2.3.2 In-Band Integrations. For in-band integrations, the switch provides the
called-party ID to a XC1000 port via DTMF signals, using the same ATIC or
E&M tie line or the same T1 channel that is selected when a call is forwarded
to XC1000. The called-party ID precedes the call.

1.2.3.3 R2 Integrations. R2 is a multifrequency in-band tone signaling plan that
sends integration data (calling and called number ID, for instance) over the
same channel used for voice connection. R2 is an enchanced version of
DTMF in-band integration. The protocol follows International Telegraph
and Telephone Consultative Committee (CCITT) standards.

1-5Edition OneXC1000 Service

SECTION 1.2 – 1.3

1.2.3.4 Common Channel Signaling/Signaling System 7 (CCS/SS7) Integra­tions. CCS/SS7 integrations provide a digital transmission for domestic

and international signaling applications. Digital transmission eliminates
the inherent noise problems that can occur with those integrations using
an analog transmission. The protocol follows CCITT standards. With
CCS/SS7 integrations, signaling and voice are separated into different
channels with the signaling for several calls contained in one channel or a
“common” channel. CCS/SS7 integrations require the use of the primary
rate interface TIC (PTIC). The PTIC provides the inter face to support 30
DLC voice channels. An adapter to the PTIC can provide either a 75-ohm
coaxial or 120-ohm symmetrical-pair connection, depending on the CO or
MTX requirements.

INTRODUCTION

1.2.4 ACP Multiple-Terminal Access

The optional ACP provides seven 25-pin RS-232 connectors for up to seven
multiple-terminal-access (MTA) SMTs to be installed, either at local or remote
locations. Up to seven administrators can access the XC1000 database from
these separate terminals to make configuration changes, review the status logs,
and perform other control functions. These seven ter minals can access
different areas of the XC1000 database simultaneously. Without the ACP MTA
option, up to three SMTs can be accessed, but the number of RS-232 integra­tion links is reduced.

XC1000 supports individual data formats for each SMT and provides each
SMT with a different access level. The ACP I/O distribution board routes all
seven channels into a single cable, which connects the ACP-MTA connector
to a CPU port.

INST ALLATION

The Installation section is composed of the following chapters:

- Chapter Two: Site Preparation

- Chapter Three: Platform Installation

- Chapter Four: Startup and Initialization

The information in Chapter Two is for preliminary work that must be
completed before the XC1000 arrives at the site. The subjects addressed
include requirements for space, environment, power, and cabling. Environ­mental requirements include air conditioning, EDS reduction, and ground­ing. Cabling requirements include cables to locations throughout the
XC1000. Instructions for installing the floor mount are also provided. The
floor mounts for the later installation of the XC1000 must be installed
during the site preparation.

Chapter Three includes information required to install the XC1000, from
the time that it arrives on the shipping dock, is transported to its final
location, and is installed on the floor mounts. During installation, the
cables prepared during the site preparation are connected, the primary SMT
and printer are installed, the logic cards are configured, the switches are
set on the main distribution board, and optional features are configured. If
a dual-cabinet XC1000, connections must be made between the two
cabinets before they are installed.

I

Following the XC1000 installation, the XC1000 is started up and initialized,
as described in Chapter Four. During initialization, the startup diagnostics
are run, the first-time setup is entered in menu 1, the line types and port
assignments are established in menu 4, and dialing and serial-channel
parameters are established in menu 6. The XC1000 is then verified and
tested and is ready for operation.

SITE PREPARATION

2.1 OVERVIEW

Before installing a XC1000, the site where the XC1000 will be located must be
prepared to meet specific requirements. This chapter contains instructions for
preparing the site, including information about equipment location; cabling
and connector requirements; and procedures for installing external power, data
links, telephone wiring, and floor mounts. The sections about cabling assist in
determining cable lengths and connector locations. These procedures should
be accomplished before delivery of the XC1000.

The customer must supply the –48 Vdc power for the XC1000 –48 Vdc input­power requirement.

Before preparing the site for installing the XC1000, refer to Chapter Ten for
descriptions of the XC1000 components. Determine the environmental and
power needs for XC1000 and observe all distance and length limitations
specified in this chapter. Use shielded cable for all telephone wiring and data
connections to external hardware. The customer is responsible for all equip­ment not supplied by Octel and for meeting XC1000 site requirements.

2.2 SITE-ENTRY CLEARANCES

XC1000 arrives at the site shipped in a crate on a pallet. Consider the following
to ensure that the XC1000 can reach the proposed site:

- Transport the crated XC1000 to the operating location or unpack the

crate and box outside and move the uncrated cabinet to the operating
position.

- Determine a route that has unrestricted passage through doorways,

halls, and elevators to the XC1000 site from the shipping dock.

2.3 SPACE REQUIREMENTS

Plan a location for the XC1000 that is close enough to the switch equipment
for optimum performance. For example, at sites using RS-232 integrations
and where the length of a data link exceeds 50 feet (17 meters), other than
telephony loop length, use customer -supplied data sets to extend the link
between the switch equipment and the main distribution board on the
XC1000. At sites using other types of integration, for example, in-band, no

SITE PREPARATION

restrictions exist for the distance between the switch and XC1000. Consider
the following factors when determining the XC1000 location:

- Allow sufficient clearance around the XC1000 for service personnel to

obtain access. Figure 2-3 shows the allowances for workspace required
around the cabinets. Enough space is required for the doors at the
front and rear of the cabinet to be opened, plus additional clearance
for working and aisle space.

- Plan a location for the primary system manager terminal (SMT) and

optional printer. If the SMT is to be located more than 50 feet from
the XC1000, a customer -supplied data set is required rather than a
direct cable.

2.4 ENVIRONMENTAL REQUIREMENTS

Communications systems require specific environmental conditions to
operate reliably. Temperature and humidity levels are important because
they affect the operation of the XC1000. Because of the prevalence of
electrical equipment in the area, fire safety is essential, as is protection
against electromagnetic interference, electrostatic discharge, and shock.

SECTION 2.4

2.4.1 Air Conditioning

The air -conditioning system for the room in which XC1000 will be installed
should maintain the air temperature and moisture content within the parame­ters shown in Table 2-1. Extremely low or high humidity can degrade system
reliability. Low humidity increases static discharge, which can damage system
components. High humidity increases the chance of condensation, which can
also damage the equipment. If the site has subfloor cabling, the air -conditioning
system must keep duct and subfloor air temperatures above the dew point.

An air -conditioning system must be operating before XC1000 is installed.
Consider the following alternatives:

- If the system in place at the switch location is not adequate for the

needs of the XC1000, either expand the capabilities of the existing
system or install a new one.

- When selecting the air -conditioning system, consider air-filtering

- Select and install the air -conditioning system in compliance with local

codes and regulations.

2.4.2 Electrostatic-Discharge (ESD) Reduction

ESD results from the static-charge buildup on two nonconductive surfaces.
If the static discharges through system components to ground, damage to
the system could result. Minimize ESD by always wearing a grounding
wrist strap when handling system equipment.

SITE PREPARATION

2.4.3 Grounding

XC1000 uses a single-point ground for electrical safety and a ground­referenced power input for proper operation of the telephony signaling
circuits. When preparing the site, prepare the frame ground wire so that it
is ready for attachment to the XC1000 when the XC1000 is installed. Use
the guidelines to prepare the frame ground wire:

- Ground each primary cabinet frame properly with a single-conductor

frame grounding wire. Ensure that this wire is connected to earth ground
or an equivalent safety ground, such as building steel, water pipe, or
grounding bar in a branch circuit power panel. This ground connection
must comply with all local, state, and national electrical codes.

- Ground each expansion cabinet frame mechanically and electrically to

a properly grounded primary-cabinet frame.

- Make sure that all grounding conductors are the same diameter as or

larger than the conductors used to carry input power.

- Do not rely on electrical circuits for frame grounding.

SECTION 2.4 – 2.5

- The safety ground should have a dc resistance to ground of 0.1 ohms

or less. Always size and route the ground conductor to stay below this
resistance specification. Use the two-point compression (or optional
swag) grounding lug supplied with the primary cabinet to connect the
ground wire to the frame.

The XC1000 was designed to be installed as an isolated ground load using
a single-point grounding system. Connect each XC1000 frame (single or
dual cabinet) separately to the nearest safety-ground bus in the building
without bridging or chaining to adjacent equipment. In a dual-cabinet
system, connect and ground the expansion cabinet to the primary cabinet
only. To ensure that the single-point ground is achieved, the XC1000 floor
mounts use a mylar barrier sheet that provides at least 10 megohms
isolation resistance between the frame and the floor.

Ground reference all telephony signaling circuits by ground referencing the
input power to the XC1000. The –48-Vdc power return lead (labeled + on
the main power -input terminal block), which runs back to a power source or
distribution panel, is strapped to the CO main ground bus. This ground bus
might be the same as the safety ground used to connect the XC1000 frame
to ground. The strap is usually installed as close to the power source or
distribution panel as practical, but it operates with equal effectiveness if
located at the XC1000 end of the power wiring configuration.

2.5 POWER REQUIREMENTS

XC1000 requires input power of –48 Vdc. The –48 Vdc power is available
when the XC1000 is installed on switching-office premises. In some cases,
where the XC1000 is installed at another location, –48 Vdc might not be

2-5Edition OneXC1000 Service

SECTION 2.5 – 2.6

available and a power converter is required. The customer is responsible for
any equipment needed to provide –48 Vdc to the XC1000 site. Table 2-2
lists input current requirements for single- and dual-cabinet XC1000s.

All cables are connected at the rear of the cabinets. Use the following criteria
to ensure correct cabling:

- Determine the cable length by using the height from the floor as a

reference for the connector location to which the cable is to be
attached.

- When a XC1000 is installed, dress the cables down or up the side of

the cabinet to a point about 60 inches (152 centimeters) above the
floor, run the cables laterally across the top of the cabinet, and drop
them to the appropriate connector.

- Mark each cable end for its termination for easy identification during

installation.

- Make sure to allow enough length, depending on whether the cables

are to be dressed on the right or left side of the XC1000 cabinet.

- If expansion to a second cabinet is planned, dress the cables on the

left side of the cabinet because the second cabinet would be installed
flush against the right of the first cabinet.

2-7Edition OneXC1000 Service

SECTION 2.6

Prepare cables to be attached to connectors in the following XC1000 locations:

- Power-distribution shelf

- Main backplane

- Main distribution board

- ACP I/O distribution board #1 (optional)

- ACP I/O distribution board #2 (optional)

- Busy-out controller (optional)

These telephone-line and cable-termination locations are described in
sections 2.6.1 through 2.6.5.

2.6.1 Power-Distribution Shelf

The cable for the –48 Vdc power input is connected to the XC1000 on the
power-distribution shelf. The power cables can r each the power-distribution
shelf either from the top or from the bottom, depending on whether the cables
are run through the ceiling or the floor. Use the following procedure to
ensure correct cabling to the power -distribution shelf:

SITE PREPARATION

1. Plan for the following current and power levels:

- 30 amperes maximum at –48 Vdc for a single cabinet and 45

amperes maximum for a dual cabinet

- Maximum power requirement, 1500 watts per cabinet

- Sufficient number of 115-Vac outlets near the XC1000 site for

peripheral devices and test equipment

2. Make sure to provide 45 ampere, –48 Vdc power if you plan to expand
to a dual cabinet in the future. This planning will eliminate having to
expand the current capacity later.

3. Install the power cables using one of the following methods:

- Drop an insulated power cable for power, return, and ground

with strain relief to reach the power -distribution shelf shown in
Figure 2-5. Although wire size depends on several installation
factors, Octel recommends using a 6-AWG or larger conductor.

1

A 1

⁄4-inch (3.2cm) conduit can be used to enclose these

conductors.

- Pull the cable or cables through a 1

under the raised floor, and route the conduit up the back or side
of the XC1000 to reach the power -distribution shelf.

2.6.2 Main Backplane

1

⁄4-inch (3.2cm) conduit

The main backplane is located on the back of the XC1000 frame and
provides the data and control-bus connections for all of the cards contained
in the logic bay, including the CPU, file cards, monitor card, and DLCs.
The main backplane also provides the connections between the TICs in the
logic bay and the CO lines or trunks. The CO trunk cables are connected
to the main backplane using 25-pair male Amphenol-type connectors.

Each cable carries 12 telephone lines to one TIC connector. For example, line
1 from the switch connects to WH-BL (tip) and BL-WH (ring) conductors in the
cable, using pins 26 and 1 on each connector. When this cable is attached to
the TIC connector on the backplane, line 1 connects to port A on the TIC.
Similarly, line 2 connects to port B, and so on. The cable for the TIC1
connector will go to ports 1A through 1L (as will appear on the SMT screen),
the cable for TIC2 will go to ports 2A through 2L, and so on.

2.6.3 Main Distribution Board

Cables for the alarm outputs, SCCS output, X.25, integration links, and the
primary SMT are connected to the distribution board, located at the rear of
cabinet 1. These cable connections are discussed in sections 2.6.4.1 through

2.6.3.5. These cables interface with the external alar ms, the SCCS interface,
the X.25/data-module, and the data-link interface.

2-18 Edition One XC1000 Service

SITE PREPARATION

2.6.3.1 SMT Connections. The SMT is normally connected to the XC1000 at the

J50 connector on the distribution board, using a male-to-male DB25 cable.
The RS-232-C interface uses pins and signals listed in Table 2-9.

SECTION 2.6

Table 2-9. RS-232-C Pins for the SMT.

Pin Abbreviation Name

1 GND Ground
2TD Transmit data
3RD Receive data
7 SG Signal ground

In addition to the primary SMT port (J50), serial ports J43, J44, and J46 can
be configured for secondary SMT connections for XC1000s using software at
Release1.5X and newer. The primary SMT port is a data-circuit-terminating­equipment (DCE) connector. Because J43, J44, and J46 are data-terminal­equipment (DTE) connectors, a null-modem adapter must be used with the
connectors. Any of these connectors can be used, but the XC1000 can
support only one primary and two secondary SMTs.

2.6.3.2 Data-Link Connections. Three RS-232 connections J44, J43, and J46 are
provided on the main distribution board for integration. The connections also
can be used for secondary SMTs. Table 2-10 lists the pin assignments.

2.6.3.3 External-Alarm Connections. Alar m relay dry-contact closures for out-of­service (OOS), service-affecting (SA), and non-service-af fecting (NSA) alarms are
located at connector J25. These relay closures can be used to activate audible
or visual alarm indicators. The dimensions to the data-link and external-alar m
connections are shown in Figur e 2-10. An Amphenol connector is used to

2.6.4.1 Integration-Data-Link Connections. XC1000 with the ACP option can support
integration data links for as many as 16 switches. Table 2-12 relates the link
number, the ACP I/O board, and the connector number. All of these 16 integra­tion data links can transmit data (TxD), receive data (RxD), and use data-carrier ­detect (DCD) signals. Integration data links 1 through 7 incorporate ready-to­send (R TS) and clear-to-send (CTS) signals. These links connect to the ACP I/O
distribution boards at the rear of cabinet 1. Figure 2-12 shows the dimensions
for the data-link connections on the ACP boards. Use DB25 male connectors for
the integration data links. Data sets must be used at sites where the length of a
data link exceeds 50 feet (17 meters).

2.6.4.2 MTA-Data-Link Connections. Up to seven remote MTA data links can be
connected to XC1000 at J111 through J117 on ACP I/O distribution board
2 (Figure 2-12). Each data link requires a shielded cable and a DB25 male
connector (refer to T able 2-12 for connector -pin assignments). T able 2-13
relates the link number with the connector number.

All of these seven MTA links can transmit data (TxD) and receive data
(RxD) with RS-232 signals. Links to MTA terminals 2 through 7 can use
data-carrier-detect (DCD) signals. All ter minals require a data set if the
cable between the XC1000 and the MTA terminal is more than 50 feet
(15.2 meters) long. (Figure 2-12 shows the dimensions to the MTA link
connections on ACP I/O distribution board 2).

3.2 ENSURING EQUIPMENT AND PERSONNEL SAFETY

Preventing injury and safeguarding the equipment must be primary con­siderations during the XC1000 installation. Safety issues include electrical,
equipment-handling, and environmental safety.

Follow the installation procedures in this chapter to prevent equipment
damage and personal injury. Safety hazards arise from the weight and bulk
of the XC1000 and the electrical connections that must be made.

3-1Edition OneXC1000 Service

SECTION 3.2

3.2.1 Electrical Safety

Before connecting the –48 Vdc primary-power leads to the XC1000, take
the following precautions:

- Make sure that the –48 Vdc branch circuit breaker is off or fuses are

removed, as applicable.

- Always connect the ground leads before the live leads.

- Make sure to check the equipment ground connection to the building

(earth) ground.

For the safety of personnel, when working on the XC1000,
always wear an antistatic wrist strap that is grounded to
the XC1000 cabinet and that contains a minimum of 1
megohm resistance from attachment to wrist. Handle cards
only by their sheet-metal stiffeners. Do not touch the
components or the edge connectors. Do not stack the cards
on top of one another. All circuit cards in the XC1000 can be
damaged by static discharge currents or by physical
mishandling.

PLATFORM INST ALLATION

Caution!

Some of the installation tasks require attaching cables to the XC1000,
grounding the XC1000, installing modules, and setting configuration
switches on telephone interface cards (TICs). When per forming any of
these tasks, follow these precautions:

- Because the XC1000 modules are sensitive to static, when working on

the XC1000, make sure to wear an antistatic wrist strap that is
grounded to the XC1000 cabinet and that contains a minimum of 1
megohm resistance from attachment to wrist.

- Be careful when handling cards; do not touch either the components

or the edge connectors.

- Do not stack the cards on top of one another.

Caution!

Keep modules that are not installed in the XC1000 in their
antistatic bags (modules are shipped in such bags). Make
sure that modules are packaged in antistatic bags if
returned to the factory.

- Always keep modules that are not installed in the XC1000 in their

antistatic bags in which they are shipped. If modules must be
returned to the factory, make sure to package them in antistatic bags.

3-2 Edition One XC1000 Service

PLATFORM INST ALLATION

Do not turn on the power to the XC1000 until the installa-
tion is complete and has been checked. To do otherwise
could damage equipment components.

- Although TICs and digital line cards (DLCs) are hot-pluggable and can

be removed and replaced while power is on, do not perfor m any
installation task with power applied to the XC1000.

- Before connecting the –48 Vdc primary-power leads to the XC1000,

make sure that the –48 Vdc branch circuit breaker is off or fuses are
pulled, as applicable. Always connect the ground leads before the live
leads. Make sure to check the equipment ground connection to the
building (earth) ground.

If an ac-to-dc converter is used at the site to supply –48
Vdc to the XC1000, an ac shock hazard can exist that can
fatally injure installation personnel.

SECTION 3.2

Caution!

Danger!

- If an ac-to-dc converter is used at the site to provide the –48 Vdc

primary power to the XC1000, the ac power itself can present a signifi­cant safety hazard. Make sure that any ac power at the site is properly
connected to the converter and that the converter is correctly grounded
in accordance with National Electrical Code (NEC) requirements.

3.2.2 Equipment-Handling Safety

The primary XC1000 cabinet (cabinet 1) weighs up to 700 pounds (317.5
kg), and the expansion cabinet (cabinet 2) of a dual-cabinet XC1000 weighs
up to 500 pounds (226.8 kg). These cabinets in their shipping crates are
even heavier. Use mechanical-lifting equipment and enough qualified
personnel to handle the XC1000 safely.

Warning!

Be careful when moving and unloading the XC1000
shipping crates, moving the XC1000 to the operating
location, and placing the cabinets onto the floor mount. The
equipment could be damaged and personal injury could
result if the XC1000 is tilted too much and falls to the floor
or on someone or is moved in a manner as to pin a person
against a hard surface.

Make sure to use caution when unloading, uncrating, and moving the
XC1000 and locating it on the floor mounts.

3-3Edition OneXC1000 Service

SECTION 3.2 – 3.3

3.2.3 Environmental Safety

The XC1000 must operate within safe environmental parameters. Environ­mental requirements are described in section 2.4.

The XC1000 depends on the positive air pressure created by the air flow
within the cabinet to maintain the temperature within operating limits. The
card cage and the disk-drive bays constitute part of an air plenum. Verify
that blank slot and drive panels, which are shipped with and installed in
the XC1000, are in the empty slots in the card cage and in the disk-drive
bays to prevent air leakage. The slot and drive panels are required for
environmental air and electromagnetic-interference (EMI) control.

3.4 INSPECTING AND UNPACKING THE XC1000

After the crated XC1000 has been delivered, inspect the cabinet crate and
the other containers for signs of damage before unpacking the equipment.
Also inspect the equipment during the unpacking process. Any damage
sustained during shipment is the responsibility of the carrier. Report all
damage to both the carrier and Octel Communications customer service.
During the unpacking process, always check the equipment and accessories
received against the packing list.

3.4.1 Inspecting the Equipment

Before opening the crate, decide whether to unpack the equipment on the
dock or to move the crate to the equipment location before unpacking. Refer
to section 2.2 for the XC1000 and crate dimensions to make sure that there
is sufficient clearance through hallways and door openings for the equipment
to pass. Perform the following steps when the XC1000 has been received:

1. Make sure that the carrier’s agent remains at the site until the un­packing and inventory have been completed.

SECTION 3.4

2. On the receiving dock, inspect the outside of the crate, including the
shock watch, and all other containers. Also, check the tilt watch,
located on the inside of the XC1000 door, which indicates whether the
XC1000 has incurred severe tilting. A replica of a shock watch and a
tilt watch is shown in Figure 3-2.

10. Using caution, roll the cabinet down the ramp, out of the crate.

3.5 INSTALLING THE XC1000

The cabinets in a dual-cabinet XC1000 must be bolted together before they
are installed on the floor mounts. Secure and level both single- and
dual-cabinet XC1000s on the floor mount, using the correct procedures.

Because a single-cabinet XC1000 weighs as much as 700 pounds (317.5
kg), placing the XC1000 on the floor mount requires several people. The
XC1000 can be mounted on a concrete or raised floor.

Warning!

Be careful when moving the XC1000 to the operating
location and placing the cabinets onto the floor mount.
Serious personal injury could result if the XC1000 is tilted
enough to fall on someone or is moved in a manner to pin a
person against a hard surface. The XC1000 could also be
damaged.

3.10 INSTALLING THE PRIMARY SMT AND OPTIONAL
PRINTER

The primary SMT shipped with the XC1000 is a Hewlett-Packard 700/43
terminal. Other terminals can be used, including the W yse 50, the DEC VT102
or VT220, and the AT&T Teletype 4425 or 5425. This installation procedure
applies to the HP 700/43 only. For information about installing other terminals,
refer to their specific manufacturer’s manuals. An optional printer can be used
with the SMT to provide hard-copy records of system menus, statistics, distribu­tion lists, usage reports, and maintenance information.

3.10.1 SMT Installation

The SMT is usually located within 50 feet of the XC1000, which is required for
a direct connection. Octel provides a 25-foot cable. If the SMT is more than 50
feet from the XC1000, modems are required. Do not turn the ter minal on until
the system is fully installed. Use the following procedure to install the terminal:

3.10.2 Printer Installation

Currently, Octel supports the Fujitsu DL1200 and the Okidata Microline
320 (ML320) printers. Other printers can be used with the proper adapta­tions. For other printer use, contact the manufacturer’s representative.
Perform the following steps to install either of the supported printers:

SECTION 3.10

1. If the printer has not been unpacked, carefully remove the printer
from its container. Save all packing materials, in case the printer
must be returned. For specific instructions about unpacking and the
physical setup of the printer, refer to the supplied printer user
manual.

2. Place the printer next to the SMT on a sturdy table or desk within 50
feet of the XC1000. Make sure the printer is within 10 feet of the
SMT.

3. Depending on the ter minal installed, use one of the following cables:

- For an HP 700/43 terminal, use P/N 057–1149–000.

- For a Wyse 50 terminal, use P/N 058–1089–000.

- For the DEC VT102 or VT220, refer to the DEC user’s manual

for the correct cable required.

- For any other terminal, refer to the supplied terminal user’s

manual.

4. Connect and secure one end of the cable to the printer adapter, as
follows:

- On the right side of the DL1200 printer.

- On the back of the ML320 printer.

3.11 CONFIGURING THE LOGIC CARDS

PLATFORM INST ALLATION

Logic cards must be configured according to the switch with which the
XC1000 interacts and according to whether the optional standby-redundancy
feature is installed. The settings of configuration switches on certain logic
cards must be verified for specific system requirements. The locations of the
TICs and DLCs in specific line-card groups and in the specific logic-bay slots
also need to be verified. Figure 3-16 shows the logic-bay slots for TICs, DLCs,
and common-control cards for both redundant and nonredundant XC1000s.

Caution!

Do not reset any switches that are not described in the
following sections. Most switches are set at the factory and
should not be changed.

Set configuration switches on the logic cards as described in sections

3.11.1 through 3.11.8.

3.11.1 ATIC and DID TIC Configurations

ATICs and DID TICs are configured for use with particular switch types at
the factory. ATICs can function as loop- or ground-start ports and provide
12 channels between the XC1000 and the switch. The line type for an
ATIC is determined in menu 4 during the initial startup.

DID TICs integrate DID trunks with the XC1000, allowing the XC1000 to
receive dial pulses or DTMF tones directly from the switch. They conduct
talk battery and signaling voltage to the telephone lines and convert
incoming analog signals to digital signals.

3.11.2 E&M TIC Configuration

E&M TICs convert incoming analog voice to digital signals. Each E&M TIC is
connected to one DLC. There are two E&M TICS and two DLCs in a line-card
group. Figure 3-18 shows the E&M TIC and DLC slot locations. Two sets of
configuration switches on the E&M TIC establish the signaling type (Type I, II, or
V) and the source of the signaling voltage. These switches are located at UX07
on the 8-switch device and at UX08 on the 4-switch device on the E&M TIC.
Table 3-5 and T able 3-6 show the settings for each signaling type supported.

1. Make sure that the ROM chips are fir mly seated in the sockets at
U5U (high byte) and U5T (low byte). Pin 1 of each chip should be
inserted in pin 3 of each socket.

2. Make sure that J1 is configured so that the jumper is acr oss pins
1 and 2.

3. Make sure that J2 is in the OFF position. J2 is a 3-pin connector that
enables and disables the pulse-code-modulation (PCM) loopback
feature. Placing the jumper across pins 1 and 2 (OFF) disables PCM
loopback; placing the jumper across pins 2 and 3 (ON) enables PCM
loopback. The jumper must be across pins 1 and 2 (OFF) for normal
operation. If there is no jumper, J2 defaults to OFF.

4. Set the line-length switches (1–8) for the appropriate configuration on
the T1 TIC (Figure 3-20). The switches allow the length of the line
between the XC1000 and the T1-span terminating equipment to be
configured to support five line-length ranges. Table 3-7 shows the
switch settings for the five T1-span line lengths.

3.11.4 E1 TIC Configuration

E1 TICs support an E1 interface that provides a digital transmission facility
of 2.048 Mb/s. An E1 TIC provides the interface to support 32 DLC channels;
therefore, three DLCs are required for each line-card group containing an E1
TIC. Two DLC channels are reserved for synchronization control and out-of­band signaling, leaving 30 channels available for voice transmission. The last
four channels on the third DLC in the group are not used.

Figure 3-21 shows the E1 TIC and DLC locations in the logic bay. Depending
on the cabinet configuration, the E1 TIC slot location will vary. In a single­cabinet XC1000, the E1 TIC is installed in slot 7. If two E1 TICs are
required, use slots 7 and 11. If three E1 TICs are required, use slots 7, 11,
and 15. In cabinet 2 of a dual-cabinet XC1000, start with slot 25.
