Notice

The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain
telecommunications network protective, operational, and safety requirements. The Industry Canada does not
guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the
local telecommunications company. The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The customer should be aware
that compliance with the above conditions may not prevent degradation of service in some situations.

Repair to certified equipment should be made by an authorized Canadian maintenance facility designated by the
supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone
lines, and internal metallic water pipe system, if present, are connected together . This precaution may be particularly
important in rural areas.

Caution:Users should not attempt to make such connections themselves, but should contact the appropriate electric
inspection authority, or electrician, as appropriate.

Notice to Users of ISDN Service

The following instructions are provided to ensure compliance with the Federal Communications Commission (FCC)
Rules, Part 68.

PRI ISDN 6.0Y 04DU9-1SN RJ48C

3 If the unit appears to be malfunctioning, it sould be disconnected from the telephone lines until you learn if

your equipment or the telephone line is the source of the trouble . If y our equipment needs repair, it should
not be reconnected until it is repaired.

4 This device has been designed to prevent harm to the ISDN network. If the telephone company finds that

the equipment is exceeding tolerable parameters, the telephone company can temporarily disconnect
service, although they will attempt to give you advance notice if possible.

5 Under the FCC Rules, no customer is authorized to repair this equipment. This restriction applies

regardless of whether the equipment is in or out of warranty.

6 If the telephone company alters their equipment in a manner that will affect use of this device, they must

give you advance warning so as to give you the opportunity for uninterrupted service. You will be advised
of your right to file a complaint with the FCC.

7 In the event of equipment malfunction, all repairs should be performed by our Company or an authorized

agent. It is the responsibility of users requiring service to report the need for service to our Company or
one of our authorized agents. For more details, see

Remote Annex 6300 Description

The Remote Annex 6300 is a Primary Rate ISDN server that houses
up to 32 modems to provide the flexibility of terminating calls
originated by analog modems, terminal adapters, and routers.

Figure 1-2 illustrates a Remote Annex 6300.

Figure 1-2. Remote Annex 6300

The Remote Annex 6300 contains two main boards:

The Remote Annex 6300 complies with the Ethernet Revision 2.0 or
theIEEE 802.3 specifications using standard Ethernet 10Base2 (Thin),
10Base5 (Thick), and 10BaseT (Twisted Pair) as the physical medium.

Main Logic Board

Processor

The Remote Annex 6300 main logic board (MLB) utilizes two 80486
DX2, 64-Mhz, clock-doubled processors.

Remote Annex 6300 Hardware Installation Guide

The MLB provides 10Base2, 10Base5, and 10BaseT autosensed
Ethernet interfaces.

Chapter 1 Introduction

PRI Interface

This interface resides on the MLB in the form of a module whose RJ45
connector is accessible through the rear panel of the Remote Annex

6300. This interface is controlled by a second 486DX2 processor , whch
also controls the internal modems.

Memory

The MLB has 8 megabytes of main DRAM, and an additional 4
megabytes of DRAM is used by the PRI interface controller.

Flash Memory

The MLB supports 2 megabytes of Flash memory.

Modem Carrier Card

Modems

PCM Codec

The Remote Annex 6300 can be configured with 0, 4, 8, 12, 16, 24, or
32 internal V.34 modems. The modems, located on quad modem
cards, are installed on the Modem Carrier Card. The modems r eceive
data from a TTL serial channel and convert the data to a modulated
analog waveform. The analog signal is then presented to a pulse-code­modulated coder/decoder (PCM codec).

The Remote Annex 6300 uses PCM codecs to convert the analog
signals coming from the modems into 8-bit serial data streams. The
data streams are multiplexed and passed to the PRI interface along
with data that is purely digital in nature, such as that used with V.120
and synchronous PPP protocols.

Firmware and Software

Firmware

The Remote Annex 6300’s ROM contains firmware for performing
power-up self-tests and loading operational code. A non-volatile
EEPROM stores the configuration parameters.

The Remote Annex 6300 can have a boot image in Flash ROM or can
receive its image from a device on the network; this image is used to
boot the Remote Annex 6300.

1-3Remote Annex 6300 Hardware Installation Guide

Chapter 1 Introduction

ROM Monitor

Supported
Configurations

When the Remote Annex completes its self tests, the console displays
the ROM monitor prompt. The ROM monitor is an interactive
command interpreter that is used to define configuration parameters.
All of the information that the Remote Annex needs to boot an
operational image is defined using the ROM monitor and its
command set. ROM Monitor commands are issued from a console
terminal connected to the console port on the Remote Annex’s front
panel. Using the ROM Monitor commands (see

❑ Modify and display a set of configuration parameters stored

Chapter 3), you can:

in EEPROM

❑ Execute interactive diagnostic tests
❑ Receive information and statistics for the hardware

configuration and the network

❑ Boot the Remote Annex 6300 manually

Once the Remote Annex 6300 has obtained a boot image and is booted,
the console leaves the ROM monitor and displays the console monitor.
(for more details, see

Chapter 2).

You can self-boot the Remote Annex 6300 from its Flash ROM, and
you can obtain full operational code over the network from one of the
following devices:

modem is transmitting or receiving data. There are 32 TX/RX
LEDs, one LED per channel, on the front of the Remote Annex

6300. For North American models, up to 32 modems can be
installed (although only 23 are active at any given time). For
European countries that use E1 lines for PRI access, a maximum
