chap28.gif
    

    Figure 12.	 10/100Base-T Ethernet RJ-45 Pinouts
    

    

    To connect the CG 6000C board to a 10/100Base-T network, you need two UTP Ethernet cables with two ferrite blocks (NMS Part Number 2761).  

    


    


    Caution:
    

    

    


    Failure to use the cables with the ferrite block may negate your Class B approval.
    

    

    


    


    

    

    

    


    For more information about the Ethernet connections, refer to Section 2.9 and  Section 3.6.
    

    

    

    2.6	 Connecting a CG 6000C Board to a T1 NetworkTop of Page
    

    


    Before connecting a CG 6000C board to a T1 network, ensure that you have:
    

    

    For more information, refer to Section 2.4.1, Setting the Board and to Section 2.4.3, Changing the DIP Switch Setting.  

    


    


    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 6000C board configured as T1 to the public network.
    

    

    


    


    

    

    

    




    CG 6000C boards have up to four 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 which allows the Central Office (CO) to perform diagnostic tests remotely.
    


    
chap212.gif
    

    Figure 13.	 CG 6000C Trunk Interface with CSU
    

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


     You can purchase or lease the CSU from the telephone company or other vendor. The CSU must be compatible with DSX-1 specifications, particularly in maintaining the pulse amplitude level between 2.3 and 4.2 volts. 

    


    


    WARNING:
    
chap211.gif
    

    

    


    Important Safety Notes 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.
    


    
chap213.gif
    

    Figure 14.	 CG 6000C 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 6000C board. The best way to provide a loopback is to simply unplug your cable from the CSU. The modular connector on most CSUs will loop back transmit to receive when nothing is plugged in.
    

    

    

    2.6.1	 Cable RequirementsTop of Page
    

    


    For FCC class approval for the U.S. (T1), unshielded cables meet Class A approval, but a ferrite is required on the ethernet cable.
    


    For FCC class approval for Europe (E1), shielded cables are necessary to meet Class B approval, and a ferrite is required on the ethernet cable.
    

    

    

    2.6.2	 Ordering T1 ServiceTop of Page
    

    


    When you order T1 service, the telephone company needs information about your system. For example, to order basic T1 service for the CG 6000C board in the United States, specify this information:
