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.

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.

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.
