Note: Install the CG 6100C hardware before you install the CG 6100C driver software from the Natural Access CD-ROM.

2.3 System Requirements

To install and use CG 6100C boards, your system must have:

• Natural Access 4.2 (or later) installed.

• A CompactPCI chassis with an H.110 compliant backplane and an available CompactPCI bus slot.
  Note: The CG 6100C board will only power up and function in a chassis with a telephony backplane.

NMS recommends an uninterruptable power supply (UPS) for increased system reliability. The UPS does not need to power the PC's video monitor except in areas prone to severe lightning storms.

2.4 Installing the Hardware

This section describes the procedures for installing the CG 6100C board in your system and connecting the board to the E1 or T1 trunk.

Caution:

The CG 6100C board is shipped in a protective anti-static container. Leave the board in its container until you are ready to install it. Handle the board carefully and only hold it by its handles. We recommend that you wear an anti-static wrist strap connected to a good earth ground whenever you handle the board.

2.4.1 T1/E1 120 Ohm Configuration

The CG 6100C board has been shipped to you configured as aT1/E1 120 Ohm board. There are no hardware changes required for the T1/E1 120 Ohm configuration. Use the software to set the board configuration by performing the following steps:

1. Set the NetworkInterface.T1E1[x].Type keyword in the board keyword file to T1 or E1.

2. Set the NetworkInterface.T1E1[x].Impedance keyword to DSX1 (for T1) or G703_120_OHM (for E1).

3. Ensure that you use the correct I/O cables as specified in Section 2.6, Connecting a CG 6100C Board to an E1 Network or Section 2.7, Connecting a CG 6100C Board to a T1 Network.
   Note: When setting the NetworkInterface.T1E1[x].Type keyword, you must specify all trunks that are being used as either T1 or E1. Do not specify more than one trunk type per board. Specify unused trunks as NONE.

2.4.2 E1 75 Ohm Configuration

Use a balun (NMS P/N 33051) to connect the CG 6100C as an E1 75 Ohm board. A 20-port balun is also available (NMS P/N 33050 or L-COM P/N ACD 2201). A balun is a transformer that converts the impedance from 120 Ohm to 75 Ohm. Configure the board as an E1 120 Ohm board.

2.4.3 Sample T1 Trunk Configuration

The following example shows a sample T1 configuration for 16 trunks:

T1
----
NetworkInterface.T1E1[0..15].Type           = T1
NetworkInterface.T1E1[0..15].Impedance           = DSX1
NetworkInterface.T1E1[0..15].LineCode           = B8ZS    [other values possible]
NetworkInterface.T1E1[0..15].FrameType           = ESF    [other values possible]
NetworkInterface.T1E1[0..15].SignalingType = CAS               [other values possible]

DSPStream.VoiceIdleCode[0..19]           = 0x7F
DSPStream.SignalIdleCode[0..19]           = 0x00

2.4.4 Sample E1 Trunk Configuration

The following example shows a sample E1 configuration for 16 trunks:

E1
----
NetworkInterface.T1E1[0..15].Type           = E1
NetworkInterface.T1E1[0..15].Impedance           = G703_120_OHM
NetworkInterface.T1E1[0..15].LineCode           = HDB3    [other values possible]
NetworkInterface.T1E1[0..15].FrameType           = CEPT       
NetworkInterface.T1E1[0..15].SignalingType = CAS               [other values possible]
DSP.C5x[0..19].cfg.XLaw            =   A_LAW                                                                                 
DSPStream.VoiceIdleCode[0..19]           = 0xD5
DSPStream.SignalIdleCode[0..19]           = 0x09

2.4.5 Keying the Chassis for CG 6100C Boards

A CG 6100C has several mechanical interlocks, called keys, which prevent the board from being inserted in a non-compatible chassis. Keying protects the board and other devices in the chassis from damage.

Before you install CG 6100C boards, configure the keying of your chassis to be compatible with the CG 6100C keying. This helps ensure that the user will not accidentally insert an incompatible board in the chassis.

This section describes how to key the slots in your chassis for CG 6100C boards. For detailed information on CompactPCI chassis keying, refer to the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0 and to the IEEE 1101.10.

WARNING:

To protect yourself and your equipment, only qualified personnel can install keying. The personnel must be familiar with the CompactPCI Computer Telephony Specification PICMG 2.5, R1.0 document.

Note: A CG 6100C board will not function in a chassis that does not have a telephony backplane.

Figure 6 shows how the CG 6100C board keys are configured:

Figure 6. CG 6100C Key Configuration

Figure 7 shows the keying chambers in a CompactPCI chassis that you must configure for a CG 6100C:

Figure 7. Keying Chamber Locations on Chassis Front and Backplane

Note: Also key rear panel keying chambers A through F (not shown above).

Refer to Keying of CompactPCI Boards and Backplanes for keying definitions.

Configure keying in your chassis as described in the following table:

Keying Chambers on Chassis	Configuration
A, B, and C (Front and rear panels)	Configure as shown in this diagram:
D, E, and F (Front and rear panels)	Configure as shown in this diagram:
P1	Verify that the male brilliant blue key is configured as shown:
P4	Verify that the male strawberry red key is configured as shown:

2.4.6 Installing the Board

WARNING:

· The CG 6100C board will only power up and function in a chassis with a telephony backplane. · If the chassis is powered up, you must install the rear panel I/O transition board before installing the CG 6100C board. · The rear panel I/O transition board cannot be hot swapped while the CG 6100C board is powered up. The CG 6100C board must be powered down to remove or replace the rear panel I/O transition board. For more information about high availability and Hot Swap, refer to the NMS OAM System User's Manual. · If your system does not operate/support the high availability model, you must remove the CG 6100C board before removing or replacing the rear panel I/O transition board.

Before you install the CG 6100C board, you need to determine which board will be the primary master and which board will be the secondary master.

We recommend that you place the board that will be the primary master in the center CompactPCI bus slot of the chassis, and that you place the board that will be the secondary master directly adjacent to the primary master board. All other H.110 boards should be placed in adjacent CompactPCI bus slots leaving no empty slots between boards.

To install the board:

1. Power down the chassis and disconnect it from the power source. (This step is suggested for new configurations.)
   Note: If you are replacing a board that is currently in the system, refer to the NMS OAM System User's Manual for any restrictions.

2. Remove the rear access panel. You must install the rear panel I/O transition board before installing the CG 6100C board.

3. If not keyed, key the rear panel I/O transition board with the same TNV1 keying as the front I/O board.

   WARNING:

   To protect yourself and your equipment, only qualified personnel can install keying. This personnel must be familiar with the CompactPCI Computer Telephony Specification PICMG 2.5, R1.0 document. NMS is not responsible if you install a CG 6100C board and chassis keying has not been properly installed.

4. Slide the rear panel I/O transition board into a slot at the rear of the chassis.

   WARNING:

   Some older CompactPCI chassis may not have a rear I/O connector alignment feature. The rear panel I/O transition board requires this feature to allow insertion. Contact the chassis manufacturer to find out if your chassis supports this rear alignment feature. Use caution when inserting the board into the backplane mating connector.

5. Seat the rear panel I/O transition board by rotating the handles.

6. Fasten the board to the chassis with the screws on the upper and lower handles.

7. To place the CG 6100C board into the corresponding chassis slot, verify that the chassis slot has the appropriate keying:

8. Strawberry red key in P4 (a chassis has P connectors). Refer to Figure 8.

9. Brilliant blue key in P1.

10. Slot keying for TNV1 levels in both the front and rear chassis.
    The keys in the backplane must have the same colors as the keys in the J1 and the J4 connectors of the CG 6100C board (the board has J connectors). Refer to Figure 8.
    Note: The CG 6100C board has been keyed prior to shipment. For more information about keying, refer to Section 2.4.5, Keying the Chassis for CG 6100C Boards.

Figure 8. Keying

Slide the CG 6100C board into the corresponding slot at the front of the chassis.

Seat the board into the backplane by rotating the top and bottom handles toward each other.

Fasten the board to the chassis with the screws on the upper and lower handles. Refer to Figure 9 for an illustration of how the CG 6100C board and the rear panel I/O transition board sit in the chassis.

Connect the chassis to its power source (if you turned it off in Step 1).

Figure 9. CG 6100C Board With a Rear I/O Transition Board

2.5 Trunk Connections

The CG 6100C board has either one or two trunk connectors, depending on whether it is an eight trunk or a sixteen trunk board. The eight trunk board has one trunk connector and the sixteen trunk board has two.

WARNING:

Important Safety Notes for Telephony Connections · Installation of this board and associated telephone wiring is to be performed only by competent technical personnel. · Make sure the PC chassis is grounded through the AC power cord or by other means before connecting the telephone line. · If your system requires an external power supply, make sure it is grounded through the AC power cord or by other means. · Never install telephone wiring during a lightning storm. · Never install telephone jacks in wet locations. · Telephone companies provide primary lightning protection for their telephone lines. However, if a site connects to private lines that leave the building, make sure that external protection is provided.

Note: Pin numbers 1 through 16 are the ring or negative transmit to the network. Pin numbers 26 through 41 are the tip or positive receive from the network.

2.6 Connecting a CG 6100C Board to an E1 Network

Before connecting a CG 6100C board to an E1 network, ensure that you have:

• Specified an appropriate NetworkInterface.T1E1[x].Type keyword value in the board keyword file.

• Specified NetworkInterface.T1E1[x].Impedance = G703_120_OHM for the keyword value in the board keyword file.

  Caution:

  NMS obtains board-level approvals certificates for supported countries. Some countries require that you obtain system-level approvals before connecting to the public network. To learn what approvals you require, contact the appropriate regulatory authority in the target country.

The CG 6100C board has up to 16 CEPT E1 interfaces. For typical E1 communications, each E1 interface connects directly to an E1 trunk, as shown in Figure 11.

Figure 11. CG 6100C Trunk Interface

Note: Trunks will not synchronize until the board is booted with NMS OAM.

2.6.1 Connecting a CG 6100C to an E1 120 Ohm

To connect a CG 6100C board configured as 120 Ohm to the E1 trunk, a shielded 50-pin Telco cable (NMS P/N 33040) is available. Connect the Telco cable to a punchdown block (NMS P/N 33039). Failure to use a shielded cable may negate your Class B approval.

2.6.2 Connecting a CG 6100C to an E1 75 Ohm

To connect a CG 6100C board to a 75 Ohm E1 trunk, use a shielded 50-pin Telco cable (NMS P/N 33040). Connect the Telco cable to the punchdown block (NMS P/N 33039) and then connect the punchdown block to a 20-port balun (NMS P/N 33050) or equivalent.

Grounding the Conductor

To ground the outer conductor of the coaxial pair, connect a ground lead to any of the four pressed-in threaded inserts on the end of the balun panel near the mounting bracket.

Use the jumper on a balun port to remove the input connector grounding. Failure to use a shielded cable between the punchdown block (NMS P/N 33039) and the 20-port balun (NMS P/N 33050) may negate your Class B approval.

Figure 12. Grounding the Conductor

The following figure shows the connectors on the front of the balun.

Figure 13. Balun Connectors

The following illustration shows the shielding diagram for the balun circuit block.

Figure 14. Balun Circuit Block Diagram

2.7 Connecting a CG 6100C Board to a T1 Network

Before connecting a CG 6100C board to a T1 network, ensure that you have:

• Specified an appropriate NetworkInterface.T1E1[x].Type keyword value in the board keyword file.

• Specified NetworkInterface.T1E1[x].Impedance = DSX1 for the keyword value in the board keyword file.

  Caution:

  You must complete all required performance tests, and a type approval certificate must be granted by the appropriate regulatory authority in the target country before you can connect the CG 6100C board configured as T1 to the public network..

The CG 6100C board has up to 16 T1 trunk interfaces. For typical T1 communications, each trunk interface connects to a Channel Service Unit (CSU) which is connected to a T1 trunk line. The CSU provides a DSX-1 interface to the T1 line and also contains circuitry that allows the Central Office (CO) to perform diagnostic tests remotely.

Figure 15. CG 6100C Trunk Interface with CSU

Note: Trunks will not synchronize until the board is booted with NMS OAM.

You can purchase or lease the CSU from the telephone company or other vendor. The CSU must be compatible with DSX-1 specifications.

WARNING:

Important Safety Note for Telephony Connections The cables attached to this product must be isolated by a Channel Service Unit (CSU) before the cables leave the building.

Alternatively, you can connect the board directly to the T1 line, without a CSU. This setup is most common in applications where the T1 line is proprietary and is not connected directly to the public network.

Figure 16. CG 6100C Trunk Interface (No CSU)

To avoid causing alarms at your T1 service provider's end, make sure that there is always a valid signal being sent, either by looping back at the CSU, or by connecting the CSU to a functioning CG 6100C board. The best way to provide a loopback is to unplug the cable from the CSU. The modular connection on most CSUs will loop back transmit to receive when nothing is plugged in.

2.7.1 Connecting a CG 6100C to the T1 Network

Use a shielded, 50-pin Telco cable (NMS P/N 33040) to connect a CG 6100C board configured as a T1 trunk to the T1 network. Connect the Telco cable to a punchdown block (NMS P/N 33039). Failure to use a shielded cable may negate your Class B approval.

2.7.2 Ordering T1 Service

When you order T1 service, the telephone company needs information about your system. For example, to order basic T1 service for the CG 6100C board in the United States, specify the following information:

Product Manufacturer:	NMS Communications

2.8 Loopback Configuration

Use a loopback configuration for your CG 6100C board to test your digital trunk application without actually connecting to the telephone network.

You will need a punchdown block with 8 RJ-48C trunk connectors (NMS P/N 33039) and a cross-over cable (P/N 31071) to set up the loopback configuration. Connect the cable from the CG 6100C to the punchdown block and then to the loopback cable on the punchdown block.

Figure 17 illustrates the CG 6100C loopback configuration connecting trunks 7 and 8, trunks 15 and 16, and trunks 5 and 13 using cross-over cables (P/N 31071):

Figure 17. Loopback Configuration

The cross-over cable connects transmit from one trunk to receive on another trunk as shown in Figure 17.

Each of the RJ-48C trunk connectors has the pinouts shown in Figure 18:

Figure 18. RJ-48C Pinouts

Figure 19 shows how the connector is wired on a loopback cable:

Figure 19. Loopback Cable
