EXNET Connect PCI H.100 Card

This section provides information on installing, configuring, and maintaining the EXNET Connect PCI H.100 card (in this document referred to as the EXNET Connect card).

Refer to the EXNET Connect Card PCI H.100 in the CSP Hardware Product Descriptions for information on the following:

The EXNET Connect card is a single card located in the user PC chassis, allowing you to connect the remote CSP nodes to H.100 voice/media processing resources within the voice/media processing unit. The EXNET Connect becomes a local switching matrix within the PC chassis, switching traffic between the EXNET ring and the H.100 resources.

The EXNET Connect card switches remote node data off the EXNET high-speed fiber optic ring and onto the H.100 bus. This makes the data accessible to any of the voice processing resources in the EXNET Connect node. In a similar manner, EXNET Connect card switches local H.100 data onto the EXNET ring, making this data available to any of the remote CSP nodes. The EXNET Connect card plugs into any voice processing subsystem with an industry standard PCI slot.

In the SCSA compatibility mode, there are 1024 timeslots available on the H.100 for transmitting and receiving data. The EXNET Connect card transmits over a maximum of 16 E1 logical spans or 21 T1 spans.

In the full H.100 mode, there are 4096 timeslots available on the H.100 for transmitting and receiving data. The EXNET Connect card transmits over a maximum of 64 E1 logical spans or 80 T1 spans.

To develop an application using EXNET Connect, your PC chassis requires the following:

The host manages all timeslot switching configuration. You can use one or more hosts for voice processing and other host-based applications. The voice processing host(s) must be aware of all voice processing resource cards in the host chassis (including EXNET Connect). It must know about each card in order to configure them at initialization, set up connections, play out prompts, etc.

Before beginning the EXNET Connect configuration, clearly map the configuration and record important information about the EXNET Connect node. This information will assist in the initialization and configuration process.

• Physical Node ID (found in decimal form on the label on the back of the card)

Electrostatic Discharge (ESD) from your body can damage integrated circuits. Use ESD protective straps, shoes, or mats when installing the PCI H.100 card.

Important! Before installing the PCI H.100 card in the PC, make sure all DIP switches have been set to the required positions.

Assign the EXNET Connect card a unique slot number between 0 and 31 (0x00–0x1F) using DIP Switch S4. The host uses this slot number for subsequent slot-related messages such as span assignments and setting the H.100 master.

EXNET Connect is designed to communicate with the voice processing host externally via Ethernet or internally via the PC parallel bus. All CSP internodal communication uses Ethernet; therefore, you must be sure to make all Ethernet connections.

2 Connect the Ethernet cable to the 10Base-T connector as shown and connect the other end to the Ethernet hub.

3 Connect the fiber optic ring connectors to fiber optic interfaces A and B as shown and connect the other ends to the CSP node.

Important! In case of using loopback connectors on the H.100 bus for testing purposes, the wiring schematic of the loopback connector depends on the bus speed. That is, the loopback connector used in case of 4 MHZ bus speed is different from that in case of 8 MHZ bus speed.

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
