Designed to extend the standard T1/E1 twisted pair or Coax network distances over fiber, this converter provides protection from environmental noise and effectively increases high-speed network reliability. The following models are described here.

When Using in a stand-alone configuration, this product is intended to be and must be used only with a Listed Direct Plug-In Power Unit marked “Class 2” and rated at 9VDC, 1 Amp. 2. This product should always be used only with the supplied power unit . 3. Models shipped with international power supplies are capable of auto switching from 100-230V, and are supplied with a U.S. type NEMA 5-15 power cable. 4. For products being shipped outside of the U.S., the user is required to install a properly grounded IEC Page 1 Page 2 Local loop-back and Remote loop-back Operational rating on relay pins 3 & 6: 0-220VDC max 2A When both Local and Remote Loop-back are set to the Normal position, the FlexPoint T1/E1 uses the default B8ZS data format. When both switches are turned to their On position, it uses the AMI data format. LED Indicators Transmit/force 1’s to fiber This switch is used to insert an “all ones” pattern into the data stream being transmitted out of the fiber port on the FlexPoint T1/E1 converter. Data being received on the coax or twisted pair will be disabled and data being received on the fiber is passed through to the coax or twisted pair side. By returning the switch to the normal position the unit will resume to normal operation. LED Color Power: Yellow Fiber: Green UTP/Coax: Green Transmit/force 1’s to Coax or UTP This switch is used to insert an “all ones” pattern into the data stream being transmitted out of the coax or twisted pair on the FlexPoint T1/E1 converter. Data being received on the fiber will be disabled and data being received on the coax or twisted pair is passed through to the fiber side. By returning the switch to the normal position the unit will resume to normal operation. Alarm Relay Contacts The FlexPoint T1/E1 converter also features dry relay contacts for optionally connecting the media converter into a separate T1/E1 alarm circuit. The relay closes when a loss of power or when signal detect is lost to the copper or fiber connection. Relay RJ-45/RJ-48 3 6 Yellow WARNING! Before inserting the Power Adapter, verify that the power on the unit is appropriate for your AC line voltage source. Attach the BNC to the FlexPoint T1/E1 converter and attach the other end of the BNC to the network equipment. Note: Use copper cables that are compliant with the specifications that are outlined in copper cable specifications. Mounting instructions: The FlexPoint Fiber Converter can be solo-mounted using a wall-mounting kit, or rack-mounted using a 5-unit shelf, or a high-density FlexPoint 14-Unit Power-Redundant Chassis. Fiber Optic Cable Attachment: Connect the fiber cables between the FlexPoint T1/E1 converters. The transmit (Tx) must attach to the receive side and the receive (Rx) must attach to the transmit side. Note: Use fiber cables that are compliant with the specifications that are outlined in fiber cable specifications. Copper Cable Attachment: RJ-45/RJ-48 T1/E1 connector Connect to the RJ-45/48 connector on the FlexPoint T1/ E1 converter via a category 3 or better cable (Category 5 is recomended) and attach the other end to the network equipment. (The twisted pair connection requires two active pairs in a T1/E1 environment. The active pairs are pins 1&2 and pins 4&5. Only dedicated wire pairs should be used for the active pins.) Set the UTP DCE / DTE switch for the RJ-45/48 port to the appropriate setting.

Local Dual Loop Back Remote & Local Loop Back Force 1’s to Fiber Force 1’s Copper T1/E1 Copper line configuration settings The T1/E1 copper line codes and line lengths are configured using dip switches located on the side of the FlexPoint T1/E1 media converter. Normal Local loop-back (L/LB) This switch will set the FlexPoint T1/E1 converter in a loop-back mode on both the fiber and copper connections. By returning the switch to the normal position the unit will resume to normal operation. Cu-Rx FO-Tx Cu-Tx FO-Rx Loopback Enabled Remote loop-back (R+L/LB) This switch will allow the entire fiber segment to be tested at either of the FlexPoint T1/E1 converters without having to set switches on both units. When set in this mode of operation the local unit is switched in a local loop-back mode. And in addition to the local loop-back mode of operation the fiber Tx port will be further encoded to carry a remote loop-back protocol. This remote loop-back protocol will set the far end FlexPoint T1/E1 converter to remote loop-back mode of operation and return a signal to the sending unit. An LED on the local and remote FlexPoint T1/E1 converters will show a confirmation that the fiber segment is communicating properly between devices. By returning the switch to the normal position it will resume to normal operation.
