RCR RQ AI Fiber Ke Input Copper Link Loss Loss of the copper input forces the T1 E1 card to generate AIS which is transmitted out the fiber port For example if Card 1 s inbound copper line breaks it will transmit AIS to Card 2 via the fiber cable Card 2 will then carry the AIS forward via its copper cable to the Central Office and send a FEF alarm to Card 1 If Far End Fault is disabled on Card 2 no FEF alarm will be sent and the fiber LK LED on Card 1 will be green Radiance T1 E1 Single Interface Line Cards 15 Customer Radiance T1 E1 Radiance T1 E1 Central green LED Site Line Card 1 Line Card 2 AIS Office O unlit LED yellow LED Copper Copper AIS carried forward Input Copper AIS If Card 1 s copper interface receives AIS the card will transmit the alarm to Card 2 which then transmits it to the Central Office and sends a FEF alarm back to Card 1 Notice that in this example the copper RX LED on Card 1 remains green since the line is intact If Far End Fault is disabled on Card 2 no FEF alarm will be sent and the fiber LK LED on Card 1 will be green Customer Radiance T1 E1 Radiance T1 E1 Central green LED Site Line Card 1 Line Card 2 Office O unlit LED AIS as yellow LED Copper AIS carried forward Input Fiber Link Loss with FEF If a card s inbound fiber line breaks the card will generate AIS which is t2. 6 Installation Guide BR Svvitch Use the Bit Error Rate Test switch to test the fiber optic connection between two T1 E1 line cards If BERT 511 is enabled on the locally managed card it will generate a 511 pattern on the data channel and request temporary loopback via the management channel The remote card will then put itself into loopback on the fiber port and send the BERT data back to the local card The default state of the BERT switch is disabled down LB Switch The LB switch enables local loopback which isolates the copper side from the fiber side This allows the incoming data on each side to loop back on their own media line and return to their sending devices The default state of the local loopback switch is disabled down For more information refer to Diagnostic Modes in the User Guide section CD Switch The line code switch determines whether AMI or B8ZS HDB3 coding is used for receiving and transmitting data The default setting is B8ZS for a T1 card and HDB3 for an El card These are the settings used in most applications AMI bipolar coding is common in legacy applica tions L2 Ll and LO Switches These switches determine the shape of the transmitter s output pulse The default is 0 0 O for T1 and 0 0 1 for El 0 down up L2 T1 Line Build Out 0 ofo DSX 1 0 133 ft 0 dB CSU fo p p E1 Line Build Out 120 ohms normal 1 22 5 dB CSU Radiance T1 E1 Single Interface Line Car
