Chapter 1. Product Description

The IBM Quad Digital Trunk Telephony PCI Adapter (DTTA), Feature Code 6312, is a full-size PCI adapter that supports 32/64-bit busses at bus speeds up to 66 MHz and is compliant with PCI Local Bus Specification Revision 2.2. Feature Code 6313 is the IBM Quad Digital Trunk Telephony PCI Blind Swap Adapter. Feature Code 6313 consists of a DTTA installed in the Blind Swap Cassette (BSC). It is intended to facilitate the use of the IBM Quad Digital Trunk Telephony PCI Adapter (DTTA) in those machines that support the BSC. The DTTA assembly consists of a base and daughter card, however the Field Replaceable Unit (FRU) for FC 6312 is the total assembly. (It should not be necessary to separate the DTTA assembly at any time). FC 6313 has two FRUs; the DTTA assembly, which is same as FC 6312, and the BSC.

The DTTA is designed to be functionally equivalent to the IBM ARTIC960RxD Quad Digital Trunk PCI Adapter (DTXA) IBM Feature Code 6310.

The adapter is designed specifically to process voice data supplied by a telephony connection on a pSeries computer using Websphere Voice Response for AIX software product, providing three functions:

The adapter also has a top card H.100 interface connection, which is the industry standard for the interconnection of multiple telephony adapters in PCI systems. This interface is used to synchronise clocks when multiple adapters are installed and to support functions such as voice recognition, FAX and channel to channel connection (tromboning).

All functional code for the adapter is provided by IBM Websphere Voice Response for AIX software product and downloaded during boot-up.

The DTTA is not intended to be connected to lines that go outside the building. It does not have the surge and isolation characteristics to meet the inter building requirement . Therefore, any lines that go outside the building need to have some type of "isolation" equipment located between line coming from the outside and the DTTA. This can be a CSU or any other type of equipment that isolates the line (i.e. that which provides the surge and isolation characteristic that meet the inter building requirement).

The DTTA conforms to CCITT G703 which states:

In the United States the DTTA has an FCC Equipment Classification "XD", 'System Ports Connecting to CSU', conforming to DSX-1 interface. When the DTTA is connected to a central office switch via a T1 trunk, the connection must be made through a Channel Service Unit (CSU). The CSU protects the circuit against power surges and allows the telephony company to test the trunk.

In other countries, a CSU or equivalent device (eg. NT1, NCTE, NPD etc.) may also be needed if the DTTA is connected to a Central Office/Network Switch. A CSU or equivalent device may also be needed if the DTTA is being connected to a PBX or channel bank etc. and the distance is such that the cable loss exceeds the requirements of G703 (6dB) or the cable exits the building.

Where 75 ohm connection is required this can be achieved with an appropriate Balun such as "Black Box Balun MT242A-M or MT242A-F". This particular Balun was certified as part of the approval testing of this adapter. However, the local telecom company may specify a particular device

.

Part Number

The DTTA Field Replaceable Unit (FRU) Part Number is 00P3119.

Note: The IBM Quad Digital Trunk Telephony PCI Adapter is an EMC FCC and CISPR Class A device.

The Federal Communications Commission (FCC) classification for this product might differ from the FCC classification for the system unit. Use the classification that is highest. For example, if the FCC classification for the system unit is Class B and a Class A card is installed, the classification of the system unit would change to Class A.

Chapter 2. Installation

Each IBM Quad Digital Trunk Telephony PCI Adapter (DTTA) package includes the following:

Hardware Requirements

The IBM Quad Digital Trunk Telephony PCI Adapter is a universal voltage 32/64-bit PCI device capable of operating in either 33 or 66 MHz slots. It can be installed in supported RS/6000's and p-Series systems. The DTTA is not "Hot Pluggable", see Note 2. under "Installing the IBM Quad Digital Trunk Telephony PCI Adapter" . For the current list of supported systems, contact the installing IBM representative.

A maximum number of DTTA's supported by a given machine is specified by the particular system unit, please do not exceed this number. Refer to the publication "PCI Adapter Placement Reference" Form No. SA38-0538 Section " Digital Trunk PCI Adapter Considerations", for correct placement of adapters. The IBM Quad Digital Trunk Telephony PCI Adapter (Feature Code # 6312) cannot coexist with the IBM ARTIC960RxD Quad DTA (Feature Code # 6310).

The following cables are needed:

(Note these RJ-48C cables are not supplied by IBM)

(See following sections for cable part numbers and installation)

Software Requirements

The IBM Quad Digital Trunk Telephony PCI Adapter will only be supported on IBM WebSphere Voice Response for AIX Program Product version 3.1 (PTF Level XXXXXX) or higher running under AIX versions 5.X or higher.

The Device Driver and Diagnostics are only shipped with IBM WebSphere Voice Response for AIX

Installing the IBM Quad Digital Trunk Telephony PCI Adapter

The following procedure describes how to install the DTTA into the system unit. The steps may vary depending on the system unit, particularly if it is a system which supports a Blind Swap Cassette (BSC). Refer to the documentation that came with the system unit for detailed instructions on performing the following procedures:

If a single DTTA (Feature Code 6312 or 6313) was ordered with a new RS/6000 or p-Series machine and there is no intention to connect to other Scbus or H.100 adapters, then DTTA is already installed in the machine, proceed directly to "Connecting a DTTA Adapter to the Telephone Network".

If multiple DTTA's (Feature Code 6312 or 63113) were ordered with a new RS/6000 or p-Series machine and their installation will suit the customer's partitioning scheme, then proceed directly to "Connecting a DTTA Adapter to the Telephone Network".

However, if DTTA's need to be moved to suit a particular partitioning scheme OR the intent is to connect to other H.100 adapters, then follow the procedure below.

If the DTTA (Feature Code 6312 or 6313) (Single or multiple) was ordered as an addition to an existing installation, then follow the procedure below.

Note 1: Ensure that the jumper JP1 is set as described in "Jumper Installation Information" If FC 6313 was ordered and it is the third or fourth instance of FC 6313, then the BSC must be disassembled before JP1 may be moved.

Note 2: The WebSphere Voice Response for AIX software product (for which the DTTA is designed) does not support replacement of adapters whilst still running. If the RS/6000 or p-Series supports adapter replacement while the machine is still powered on (but with the adapter slot powered off using a machine utility) the WebSphere Voice Response software must be stopped before any such operation.

H.100 Connections

All DTTA, and any other H.100 adapters in an RS/6000 or p-Series must be connected together using an H.100 top-connector cable. This is to synchronise clocks on the adapters and to support functions such as voice recognition and channel-to-channel connection (tromboning). H.100 is the industry standard for connection of telephony adapters in PCI systems.

To make connection easier, install H.100 adapters in adjacent slots in the RS/6000 or p-Series system unit.

Two cables are available as feature codes, along with three cable specify codes for Feature Code 2877. (see Table 1). Order the required cable(s) to suit the application. When using multiple DTTAs in a partition, the correct Grouping Indicator must also be specified.

Table 1. H.100 Cables fo DTTA Adapter

Feature Code Cable
2877 4-way H.100
4353 8-way H.100
9007 2 Slot Grouping Indicator
9008 3 Slot Grouping Indicator
9009 4 Slot Grouping Indicator

Normally use cable F/C 2877 for up to 4 adapters in adjacent slots.

Cable F/C 4353 can be used when adapters are not in adjacent slots.

Synchronisation of Trunk Clocks

DTTA trunk interfaces are designed to operate in a clock-slave mode where the adapter attempts to recover the clock from the received signal and synchronises its transmit clock to this recovered received clock. If the network or PBX is not configured as a clock master, incorrect operation and clock instability may result.

For DTTA systems, unsynchronized trunk clocks can be handled by the adapter but it adjusts the internal clock in order to normalise all clocks to the internal bus using a clock slippage algorithm. This will probably not be noticeable on voice, but may result in excessive data errors if trunks are being used for other types of data, such as fax.

For this reason, it is strongly recommended that all trunk clocks be synchronised (this will probably be the case naturally with direct network connections, but channel banks may require some special attention).

Jumper Installation Information

Jumper JP1 is used to terminate each end of the H.100 chain, and should be set as follows:

If the adapter to be installed is NOT connected to either end of the

H.100 Cable (see the illustration on page 12), then set the jumper as

shown in Figure A, to the right.

If the adapter to be installed is connected to either end of the H.100

Cable (see the illustration on page 12), the jumper must be installed

as shown in Figure B, to the right.

If the adapter to be installed is the only DTTA in the

system, then set the jumper as shown in the illustration to the right.

This is the factory setting.

Connecting H.100 Adapters Together

Prerequisites

Before connecting the H.100 adapters together, note the following:

• H.100 adapters should ideally be in adjacent slots.

• For H.100 adapters, the termination jumper JP1 must be set for the adapter at each end of the chain. For details see the section " Jumper Installation Information".

IBM Quad Digital Trunk Telephony PCI Adapter Internal Cabling

Multi-drop cable assemblies are used to connect the internal busses of installed DTTA's. There are two top card cables, FC 2877 and FC 4353 along with three Grouping Indicator codes for FC 2877.

FC 2877 and FC 4353 are used to connect multiple DTTA's to each other as well as other adapters with H.100 connectors, see below. FC 2877 cable is just long enough to connect four adapters that support H.100 connectors in adjacent slots. FC 4353 can be used for more than four adapters and/or to bridge gaps between adapters.

H.100, 4-Drop Cabling: The DTTA's have H.100 top card connectors.

The following figure illustrates the internal cabling for the DTTA's with the H.100 top card connectors cabled together. Up to four DTTA's are supported and must be in adjacent slots. Refer to "Jumper Installation Information " to position the jumper on JP1 on the base card.

4 Drop H.100 Cable

Attention: Do not connect or handle the cable during a lightning storm.

Connecting a DTTA Adapter to the Telephone Network

Prerequisites

One to four RJ-48C telephony cables for each DTTA adapter. See Section "Cables and Connectors"

Procedure

Connect the appropriate RJ-48C cable from the telephony network to the desired port on the DTTA. Making sure that the transmit-to-network pins at one end are connected to receive-from-network pins at the other end, and vice versa. See Section " Cables and Connectors"

Note: The 4- RJ45/RJ48C ports of the DTTA adapter are numbered 1, 2, 3 and 4. These will correspond to WebSphere Voice Response for AIX trunks numbered:
