1 The Primary Rate system

1.1 Introduction

This manual has been written to provide users of the Primary Rate

system with all the necessary information to configure and operate the

system. This chapter provides a brief introduction to the system and it’s

components. Chapter 2 provides information on the Primary Rate

system. Chapter 3 provides detailed information on configuration and

operation.

Please refer to Section 5 for the abbreviations found in this manual.

1.2 This is the Primary Rate System

The Primary Rate system is a Primary Rate ISDN product offering;

• Each primary rate module provides up to 30 active channels (23

for USA), each of which can operate at, or be rate adapted up to

64 kbit/s for X21, V35 or V24 data access

• N x 64 kbit/s services

• Multiple rack and PRI card operation together with high density

access and backup applications.

The Primary Rate system is incorporated in the Fivemere SBU6C, or

SBU14C shelves; it is not available as a standalone system.

Three types of PRI module are available as follows:-

CBUPRI/E1 SBUPRI-23/30 User Manual

80-14005000-011–2

• CBUPRI/E1 - this is the first iteration, providing 2.048Mbit/s ‘E1’ type

ISDN access

• SBUPRI-30 - the later version with the same features as CBUPRI/E1,

but with capacity for future expansion

• SBUPRI-23 - as for SBUPRI-30 but is a 1.544Mbit/s ‘T1’ ISDN access

version for the USA market.

The CBUPRI/E1, SBUPRI-23 and SBUPRI-30 are similar in appearance

and use; the Configuration menus vary however. To simplify matters,

this manual refers to “SBUPRI” throughout referring to all three types;

differences where they exist are specified for each type.

The system comprises:

Front (Application) Card Rear (Interface) Card

PRI ISDN Card

(CBUPRI/E1 or SBUPRI-23

or SBUPRI-30)

PRI ISDN Interface Card

(RJ-45 Connection)

Shelf Manager Module

(SBUGSM, or SBULSM)

This controls all cards via a

common command port

Other Application Cards These define what type of data

interface is presented to the

user’s equipment

For cards other than the SBUPRI used in the SBU14Cor SBU6C, please

see the relevant manual.

Management is provided via the Shelf Manager Module (SBUGSM or

the later SBULSM) in the system.

Local or Remote access to the cards in the shelf is by password which is

entered the first time any card in the shelf is polled. Alarm messages

from all application cards in the shelf are routed to the alarm and/or

command ports on the Shelf Manager Module.

Configuration commands are issued to the cards from the management

console or Fivemere proprietary Network Management System (SBU-

NM) via the Shelf Manager Module.

The Primary Rate system

80-14005000-01 1–3

1.3 The Primary Rate Interface Module

As with all Shelf System cards, the Primary Rate Interface Modules

(SBUPRI) comprise a front and a rear card. Both front and rear cards

are not interchangeable between the CBUPRI/E1, SBUPRI-23 and

SBUPRI-30 modules. See Figure 1 in section 2.2

The SBUPRI work in conjunction with other modules in the Primary Rate

system, ‘standalone’ operation is not possible. The SBUPRI provide up

to 30 ‘B’ channels (23 for USA) for use by other application cards in the

Primary Rate system.

The CBUPRI/E1 and SBUPRI-30 works with ‘Euro’ Primary Rate (I.421)

ISDN. The SBUPRI-23 works with US National standard (Bellcore NI-2).

All 3 types have a physical interface provided by an RJ45 connector.

1.4 Shelf Manager Module (SBUGSM or SBULSM)

The Shelf Manager Module is responsible for configuring the cards and

for collecting ALERTs from all application cards. A full description of the

Shelf Manager Module can be found in the SBU Systems User Guide,

which is provided as part of the documentation set.

1.5 Quad User Modules

These modules are in two forms; the Quad Low Speed Module

(SBUQLS/SBUQLB) and Quad High Speed Module

(SBUQHS/SBUQHB). Please see the Quad User Modules manual for

further details.

Additional module types will be added to the system in due course as

part of the continuing development program on these products. Further

supporting manuals will be produced for additional modules.

1.5.1 Quad Low Speed Module (SBUQLS/SBUQLB)

The SBUQLS provides four rate adapted User ports per card offering

standard V.24, X.21, and V.35 interfaces. The interfaces are chosen by

selection of the desired type of interface card for all four ports. Each

port has Talkwire capability.

CBUPRI/E1 SBUPRI-23/30 User Manual

80-14005000-011–4

1.5.2 Quad High Speed Module (SBUQHS/SBUQHB)

The SBUQHS provides four User ports per card offering N x 64k data

rates on each port, with X.21 and V.35 interfaces. The interfaces are

chosen by selection of the desired type of interface card for all four ports.

The Primary Rate Interface Module

80-14005000-01 2–1

2 The Primary Rate Interface Module

2.1 Introduction

The Primary Rate Interface Module (SBUPRI) works in conjunction with

the other modules in the Backup system and ‘standalone’ operation is

not possible. The SBUPRI provides up to 30 ISDN ‘B’ channels (23 for

USA) for use by other application cards in the system.

Management is provided via the Shelf Manager Module.

Access to the cards in the shelf is by password which is entered on the

first poll of the shelf. Alarm messages from the cards in the shelf are

routed to the alarm and/or command ports on the Shelf Manager

Module.

The front card carries out the call processing functions, the rear card

carries the line matching/isolating transformers. Both front and rear

cards are not interchangeable between the CBUPRI/E1 and SBUPRI-

23/30 modules.

2.2 Front and Rear cards

The panel layouts for the front and rear cards that make up the SBUPRI

are shown in Figure 1 overleaf. The ‘Master’ LED is labelled ‘Talkwire’

on the earlier PRIM, but the function is not implemented.

The SBUPRI provides up to 30 x 64kbit/s ‘B’ channels (23 for USA),

each channel can be switched to any time-slot on any of the four

2.048 Mbit/s backplane buses.

The SBUPRI will provide on demand individual 64 kbit/s channels for

use by other application cards in the shelf. The other application cards

are completely responsible for the provision of telephone numbers,

CLIDs, dial commands, timers, and call retry attempts.

Software download to the card is supported via the Shelf Manager

Module.

2.3 Shelf Power Loading

The SBUPRI requires the following current on the power rails:

+5V +12V -12V

250mA 0mA 0mA

When installing cards into either type of shelf, the installation engineer

must ensure that the shelf power supplies’ combined output can meet

both the overall power requirements and the individual rail current

requirements of all the cards in the shelf. (Please refer to the relevant

manuals for this information on the cards). This is true whether allowing

for redundancy or not.

Warning:

The Shelf should be professionally installed by a competent

engineer. There are no operator serviceable parts inside the

unit and it should only be opened by a qualified service

engineer. The mains supply should be disconnected before

accessing the interior.

2.5 SBUPRI Error Conditions

Error conditions on the SBUPRI are all associated with the physical PRI

and are described in the following sections; there are two varieties of

error condition:

• Conditions associated with the actual physical PRI

• Other error conditions on the card

CBUPRI/E1 SBUPRI-23/30 User Manual

80-14005000-012–8

2.5.1 Physical PRI Error conditions

• AIS/Blue received (Alarm Indication Signal - from local NT)

• RAI/Yellow received (Remote Alarm Indication - from remote NT)

• RED Loss of Frame Alignment

• RED Loss of signal

• Detection of CRC Errors

The last three are all locally sensed conditions from the NT.

2.5.2 Consequent Actions to Error Conditions

A number of consequential actions take place when one or more of the

error conditions listed in the section above occur. These are detailed in

the following sub-sections.

2.5.2.1 Remote Alarm Indication

RAI is transmitted from a remote unit as a result of detecting any of the

following:

• Loss of signal

• Loss of Frame Alignment

• Received Alarm Indication Signal/Blue

2.5.2.2 CRC Error Information

CRC Error Information is generated in the PRI (see section 2.4.1) as a

result of the following:

• Loss of Signal (But only when Loss of Frame Alignment has not yet

occurred)

• Detection of Incoming CRC Errors. When excessive errors are

detected, line re-synchronisation is performed. At this point the unit

detecting errors will issue a Red alarm.

The Primary Rate Interface Module

80-14005000-01 2–9

2.5.3 Major Equipment Failure

The only ‘other’ error condition - this occurs when the watchdog timer on

the card expires indicating a major problem. Software restart will then

occur (as at power up).

2.6 Status LEDs

The status LED’s are illuminated under the following conditions:

LED Colour Conditions

Channel in

Use (1-30)

Green When a call is up,

i.e.

the relevant channel

2.8 Management and Control

The SBUPRI operates in conjunction with a Shelf Manager Module for

configuration purposes so there is no directly connected command port.

Under normal conditions the majority of commands are initiated by other

application cards via the system bus so only a limited set of commands

are available directly to the user.

Please see the manual on the SBU Systems for details of how to use the

Shelf Manager Module.

SBUPRI Command Menu

80-14005000-01 3–1

3 SBUPRI Command Menu

The SBUPRI uses a command menu structure similar to other Fivemere

products. Some menu options are marked with an asterisk (*) to indicate

that they are unavailable - this is to maintain the overall menu structure

across the product range. The following sub-sections describe the

menus.

The following commands have a special meaning and are executed with

single keystrokes:-

S Displays the status information for all channels of the SBUPRI.

T Returns to the top level menu.

X Goes back (up) one level in the menu system.

Where (F) in the text is stated, this is the factory default setting.
