1. INTRODUCTION

USING THIS MANUAL

1.01 This document contains both an overview of the Fiber RSC

configuration and the guidelines for provisioning and set-

ting up the Administration and Maintenance interface. Read the

first three chapters to obtain an understanding of how the con-

figuration allows the host ISDN office to be remotely located.

Read the remaining chapters to obtain the step-by-step procedures

that ensure that the Fiber RSC is correctly provisioned and main-

tained.

PURPOSE OF THE FRSC

1.02 With Integrated Services Digital Network (ISDN), the Oper-

ating Company can provide, using a single interface, both

voice and data services to its customers. Refer to 297-2401-100

for a description of the ISDN protocols and the types of services

offered. Included is a description of the LGCI-LCMI configura-

tion, which is used to offer services from a local office.

1.03 Due to distance limitations of the host network links, the

LGCI-LCMI configuration cannot offer ISDN services to

remote sites. The Fiber RSC (FRSC) allows the Operating Company

to place the LGCI-LCMI configuration at a remote site by trans-

parently extending the host network links with the use of optical

fiber transmission facilities.

SOFTWARE IDENTIFICATION

1.04 Software applicable to a specific DMS-100 Family office is

identified by a BCS release number and by Northern Telecom

(NT) product engineering codes (PEC). The significance of the

BCS number and the PEC is described in 297-1001-450 (section

450/32) and in the office feature record D-190.

1.05 A display of the BCS number and PEC for the NT feature

packages available in a specific office can be obtained by

entering the following command string at a MAP.

PATCHER;INFORM LIST;LEAVE

1.06 The information contained in this Practice applies to

Batch Change Supplement (BCS) 29. Note, however, that

although the FRSC hardware is available in BCS29, the FRSC con-

figuration will work with an ISDN host office that contains a

previous BCS release.

2. OVERVIEW OF THE FRSC

THE LGCI-LCMI CONFIGURATION

2.01 Figure 1 on page 10 gives a block diagram view of the

LGCI-LCMI configuration as it applies to a local office.

Refer to the following sections of the following documents to

better understand this configuration and its capabilities:

* 297-2401-100, Section "Components of the Exchange Termination

for BRA". This section gives a physical description of the

LGCI and LCMI.

* 297-2401-102, Section "Providing Service." This section

explains the audiences involved in setting up and testing the

different loops.

* 297-2401-102, Section "Trouble Reporting and Clearing." This

section explains the trouble indicators of the LGCI-LCMI and

provides procedures to clear the trouble.

* 297-2401-103, Sections "ISDN Line Concentrating Module" and

"ISDN Line Group Controller." These two sections provide a

functional description of the LCMI and LGCI.

HOW THE FRSC INCLUDES THE LGCI-LCMI CONFIGURATION

2.02 Figure 2 on page 12 gives block diagram of the FRSC.

Refer to this figure while reading these paragraphs.

Note: Figure 2 on page 12 shows neither the location of the

packet handler (which may be located at either the host or the

remote), nor link provisioning. Refer to Connections to the

Packet Handler on page 28 for more information.

2.03 Placing the LGCI-LCMI configuration at a remote site is

done by extending the DS-30 links to the LGCI at a remote

site over a DS-1 transmission system. With the FRSC, the follow-

ing conversions occur:

1. The DS-30 format network ports are converted at the Host Link

Extension (HLE) Frame into the DS-1 format.

2. The DS-1 format signals are routed to the optical equipment

where they are converted to the DS-3 format and then to fiber
