E1/T1 cPCI card – Installation Guide

1 Introduction

1.1 General

This installation guide is for the Aculab E1/T1 Compact PCI (cPCI) card. The Aculab E1/T1 cPCI

card is a digital network access card with up to eight E1/T1 ports. The network ports are

provided by Aculab primary rate modules (PMs) with four E1 or T1 ports (PM4 modules).

This product is referred to as the 'E1/T1 cPCI card’ in this document unless the context requires a

more specific term.

The design of the Aculab E1/T1 cPCI card allows primary rate ISDN network connections to be

made via RJ45 connectors on the front face of the card. Connection can also be made via an

optional ‘transition module’ card with RJ45 connectors at the rear of the CompactPCI© chassis.

The advantage of the transition module approach is that the E1/T1 cPCI card can be removed

and replaced without disturbing the network connections.

CAUTION When the transition module is used for network connection, do not attempt to simultaneously connect to the network using the front

panel RJ45 connectors. Only one connector may be used for each network port. Misuse will invalidate telecommunications approvals.

The Aculab E1/T1 cPCI card and transition module

Note If the card is supplied with only one PM4 module fitted, ports 4-7 on both the endplate and the transition module are inactive. Blanking

plugs are normally fitted to the inactive ports.

To avoid problems when replacing or swapping cards, care must be taken to ensure that the

replacement card has the same functionality as the card it replaces.

When providing both E1 and T1 network connections from the same cPCI card, standard

practice is to set the top module (ports 0-3) as E1 and the bottom module (ports 4-7) as T1. It is

not possible to have mixed E1/T1 ports on a single PM module.

The serial number of the E1/T1 cPCI card is used to uniquely identify an E1/T1 cPCI card in the

system. The serial number is hard coded into the card firmware by Aculab, and a label detailing

the number is placed on the reverse of the card (no components) on the leading edge. It has the

format P/N ACXXXX S/N XXXX WONXXX, S/N denotes the serial number.

Note As required, make a note of the card serial number before fitting the card to the chassis. The serial number will then be available

when installing the device driver software without having to remove the card unnecessarily.

The Card installation section, details the installation of the E1/T1 cPCI card into a host chassis, and

subsequent connection to the network.

E1/T1 cPCI card – Installation guide

The Approval information section, in conjunction with the country-specific appendices, gives the

conditions of the approval for connection to the telephone network, requirements for installation

and safety, and other regulatory matters. This section and the appropriate country-specific

appendices contain statements regarding your use of the E1/T1 cPCI card that are legal

requirements for connection to the public network. Failure to use the E1/T1 cPCI card in

accordance with any of these instructions for use may invalidate the approval for connection.

Note These instructions for use assume that these various elements are being assembled and integrated by someone competent in such

matters.

1.2 Uses of the E1/T1 cPCI card

The E1/T1 cPCI card is a plug-in card suitable for use in many different types of CompactPCI©

compatible chassis. Up to eight E1/T1 ports, on two Aculab plug-in PM4 modules, provide a

means of connection to a digital telephone network. The E1/T1 cPCI card provides an interface

between the telephone network and the H.110 CTBus. The H.110 expansion port enables

connectivity with various types of CompactPCI©based speech and data products from different

vendors using an H.110 compliant interface. With the CompactPCI©specification, the H.110

connections between cards are integrated into the CompactPCI©backplane.

The E1/T1 cPCI card contains a digital switch matrix that allows arbitrarily switched

interconnection between 240 channels on the E1-network or up to 192 channels on the T1-

network and the 4096 speechpaths (timeslots or channels) on the H.110 CTBus. These speech

paths can be switched through the signalling DSPs and to the telephone network via up to eight

E1/T1 ports.

Control of the E1/T1 cPCI card is via a low-level interface ported to the CompactPCI©bus. The

card is essentially operating system independent, and may be used in a UNIX, Windows NT, or

indeed any other operating system environment, using a suitable device driver. Call control and

digital switch control functions are provided via device drivers that are described in separate

publications specific to those topics. Please contact Aculab Plc for information on device driver

availability. Drivers and additional documentation are available for download from the Aculab

web site. http://www.aculab.com

Note The E1/T1 cPCI card is not a complete product, and only has usable functionality when associated with a host chassis and an

application program.

1.3 Telephone network attachment

The E1/T1 cPCI card with revision 1.5 E1 PM4 Line Interface Modules fitted, attaches to the

2Mbit digital system or Primary Rate (2.048 Mbit/s) Integrated Services Digital Network (ISDN).

Network attachment is via a service provision often used to connect digital PBXs to the

telephone network (NT1). It is available with 4 or 8 primary rate ISDN ports and so may make or

receive 120 or 240 separate calls at a time.

The E1/T1 cPCI card with revision 1.5 T1 PM4 Line Interface Module fitted, attaches to the

1.544Mbit digital system via a Channel Service Unit (FCC, IC or UL Listed CSU). It is available

with 4 or 8 primary rate T1 ports and so may make or receive 92/96* or 184/192*separate calls

at a time.

The E1/T1 cPCI card with revision 2 E1/T1 PM 4 line interface modules fitted, attaches to either

an E1 (2Mbit) or T1 (1.544Mbit) digital system as detailed above. It is available with 4 or 8

primary rate ports and subject to each port configuration may make or receive between 92 and

240 separate calls at a time. Each individual ports driver is software configurable for either T1 or

E1 (75 or 120 Ohms).

* T1 capacity is signalling system dependent.

CAUTION When making a network connection, to reduce the risk of fire, only telecommunications line cord of 26 AWG or larger may be used.

Please refer to the appendices for more details of the various international connections.

Port 2 2 x J17, J4 & J8 Port 2 2 x J4

Port 3 2 x J18, J3 & J7 Port 3 2 x J3

When the jumpers associated with the E1 port are fitted. The interface impedance is 75 ohms

When the jumpers associated with the E1 port are NOT fitted. The interface impedance is 120

ohms

Note Different impedance can be supported on the same E1 variant module;

Note The revision 2 modules can simultaneously support both E1 and T1 ports. Earlier revisions could only support either E1 or T1 as they

required different E1 or T1 variant modules.

Note Besides E1 and T1 ports requiring different firmware, E1 firmware also needs to support both 75 and 120ohms, for example, ETS300

firmware uses a switch –s61,1 for 75ohms (default 120ohms), but E1 DASS requires the firmware DASS75 for 75ohms working.

Refer to the Call, Switch and Speech Driver Installation Guide for further details

To connect to 75ohm E1 networks, RJ45 to BNC adapters are needed. The correct configuration

of these adapters is shown below:

E1/T1 cPCI card – Installation guide

1.5 E1/T1 cPCI card - host interface

A device driver program, running on the host chassis, controls the operation of the E1/T1 cPCI

card.

The driver accesses the card via a control space within an area of shared RAM. This shared area

is a block of memory physically resident on the card that appears as a normal area of memory in

the memory map of the host chassis.

For information on device driver installation and configuration, please refer to the Aculab

publication ‘Call, Switch and Speech Driver Installation Guide’. This guide can be downloaded

from the Aculab company web site at www.aculab.com.

1.6 Call control

Processors on the PM4 module daughter-card (one processor per E1/T1 port) control all of the

call signalling (set-up, acceptance, clearing, etc.) in response to commands from an application

program running on the host chassis.

The call control interface to the PM4 module is at a low level (in signalling terms), and this

provides maximum information and control over the various stages of call progress. This

interface is accessed via a device driver that has been prepared for the operating system in use.

The PM4 module processor checks each outgoing message provided by the application program

for syntax, validity of content and context. If errors are found, the call is automatically cleared.

The software on the PM4 module, therefore, forms an effective barrier between the application

program and the telephone network, and protects the network from incorrect call signalling.

Several elements of call signalling related information are available to the application program,

although in some cases this depends upon provision by the Public Switched Telephone network

(PSTN) of certain information along with each call. One such information element is the number

used by the caller on calling into the card, (the DDI number); this is only available when the

service obtained from the PSTN is of the appropriate type. Another such information element,

which may be available according to the protocol and PSTN, is Calling Line Identity (CLI),

which, on incoming calls, makes the telephone number of the calling party available to the

application program.

Full details on the control of calls using the E1/T1 cPCI card are available in a separate

publication ‘Aculab Call Control API Guide’. This guide can be downloaded from the Aculab

company web site at www.aculab.com.

1.7 Speech and data paths

Speech and data associated with telephone calls are not terminated on the card, but are always

switched without modification to other cards, or on-board modules, for processing. The card

maintains bit integrity within timeslots between ports on the card.

There are two categories of multi-channel path provided by the card. The figures in part 1 below

are for one PM4 module. The fitting of a second E1 or T1 PM4 module will increase the call

handling capacity accordingly.

1. E1 (G703) ports - 120 calls (2Mbit system or ISDN) per E1 PM4 or

T1 (G703) ports - 92/96 calls (1.554Mbit T1 system or T1 PRI) per T1 PM4

2. The H.110 CTBus — 512 bi-directional speech paths (out of a possible 4096)

Additionally, any one 'source' of speech or data may be distributed to a number of separate

'sinks', but note that it is not possible via switching on the card alone, for more than one source

to feed a single sink.

E1/T1 cPCI card – Installation Guide

Full details on the switching of calls using the E1/T1 cPCI card are available in a separate

publication ‘Aculab Switch Control API Guide’. This guide can be downloaded from

http://www.aculab.com.

1.8 H.110 CTBus loading

The E1/T1 cPCI card has a loading factor of 1 on the H.110 CTBus. The maximum loading

allowed on the H.110 CTBus is 20. The total loading is calculated by adding the loading factor

of all the devices on a single H.110 CTBus.

E1/T1 cPCI card – Installation guide

2 Card installation

The installation procedure for expansion cards will vary from one type of host chassis to another,

and the exact details of the installation procedures for expansion cards must be sought in the

user guide supplied by the host chassis manufacturer. However, in general:

• do not connect the E1/T1 cPCI card to the 2.048/1.554 Mbit/s service or primary rate ISDN

network termination port until this document, and in particular the sections marked

'Installation and Safety', have been read in full and understood.

• proper ESD (electrostatic discharge) procedures should be maintained throughout.

CAUTION Care must be taken when inserting CompactPCI cards or transition modules into the host system. The contact pins in the host system

can easily be bent if undue force is applied during card insertion, or if the locking tabs are engaged without the card being properly

aligned. Aculab accepts no responsibility for damage to the host system connectors arising from miss-use of the E1/T1 cPCI card.

To install the card to the host with the power off:

1. Locate a vacant CompactPCI©slot and remove the host chassis CompactPCI©slot cover.

2. Inspect the back-plane connector for any bent pins.

3. Slide the card in to the CompactPCI©slot making sure the alignment pins at the top and

bottom of the end plate engage in their sockets. Using light finger pressure only, ensure the

card is correctly aligned and pressed into the connector. When you are satisfied that the

card is positioned correctly, engage the upper and lower levers simultaneously. The levers

will click to indicate they are locked.

4. Locating screws may be fitted to secure the top and bottom of the card.

5. Optional: If the Aculab cPCI transition module is being used, repeat steps 1, 2 & 3 at the

rear of the chassis with the matching rear slot cover and the Aculab cPCI transition module.

Particular care must be taken to avoid connector pin damage, as the transition module is

more difficult to align than the E1/T1 cPCI card.

6. If necessary, install the driver and application firmware as detailed in ‘Call, Switch and

Speech Driver Installation Guide’.

7. If necessary, install the application software as detailed in the appropriate documentation.

This completes the installation of the E1/T1 cPCI card into a non-running system.

To ‘hot swap’ the card in a running host system:

1. Make sure you have a replacement E1/T1 cPCI with the same functionality as the card being

removed.

2. Identify the card that needs to be changed. This identification process may involve

examination of the card LEDs and/or information from the application using the card.

3. When you are satisfied that you have identified the card to ‘hot swap’, remove the locating

screws (at the top and bottom of the card, if fitted). Press the red release button to unlock

the lower lever, but do not operate the lever to remove the card.

4. There is a single blue LED on the end plate of the E1/T1 cPCI card. Only when this LED is lit

is the card then ready to be fully removed. Press the red release button to unlock the upper

lever, then simultaneously operate both levers and slide out the card to fully remove it.

5. Inspect the backplane connector for any bent pins.

top and bottom of the end plate engage in their sockets. Using light finger pressure only,

ensure the card is correctly aligned and pressed into the connector.

7. There is a single, blue LED on the end plate of the E1/T1 cPCI card. Only when this LED is

lit and you are satisfied that the card is positioned correctly, engage the upper and lower

levers simultaneously. The levers will click to indicate they are locked.

8. Locating screws may now be fitted to secure the top and bottom of the card.

This completes the ‘hot swap’ of the card in a running host system.

E1/T1 cPCI card – Installation Guide

2.1 E1/T1 cPCI card LED usage

The Aculab E1/T1 cPCI card has a block of eight LEDs visible on the endplate of the card. These

LEDs are labelled, and each one corresponds to a port on the card. If the card is fitted with one

PM4 module, then the LEDs for those four ports will operate and the LEDs for the unused ports

will be off. A solid, red LED indicates the port in RESET. A green LED indicates activity on that

port.

The single, blue LED is used during the ‘hot swapping’ of cards to indicate that a card can be

removed or replaced safely.

2.2 PM4 module LED usage

There are 12 surface mounted LEDs on PM4 modules. The LEDs are arranged in four rows, one

for each port.

LED A, LED B, LED C - PORT 3

LED A, LED B, LED C - PORT 2

LED A, LED B, LED C - PORT 1

LED A, LED B, LED C - PORT 0

Current production is LED A red, LEDs B & C green.

While a port microprocessor is in the reset state, the LED A is on. It will go out when firmware is

downloaded to the port. LED B turns on briefly during firmware download.

ISDN protocols

LED B flashes when layer 1 transmits a frame. LED C flashes when layer 1 receives a frame. The

state of LEDs B & C indicates the state of layer 1. When LEDs are off, layer 1 is inactive, and the

LEDs will flash on to indicate frames.

When both LEDs are on, layer 1 is active (F1 or F2 state), and the LEDs will flash off to indicate

frames.

CAS protocols

The state of LEDs B & C indicate line state. When both LEDs are off, there is a line problem (for

example, no signal or loss of sync). When both LEDs are on, the line is active and LED B (LED C)

will flash off when a digit is transmitted or received.

Note If the power supply voltage goes outside of tolerance, the board will go into the reset state. This is indicated by all four of the A (Red)

LEDs being on.
