SW3 - FORCE 1S TO FIBER “FO1”

When this DIP-switch is set to the “FO1” position, an “all ones” pattern is inserted into the data stream being transmitted out of the fiber port on the T1/E1 converter. Data being received on the coax or twisted pair is disabled and data being received on the fiber is passed through to the coax or twisted pair side. A blinking “Tst” LED on the remote T1/E1 shows confirmation that the fiber segment is communicating properly between the devices. By returning the DIP-switch to the “Norm” position, the unit resumes normal operation.

SW4 - FORCE 1S TO COAX OR UTP “CU1”

When this DIP-switch is set to the “Cu1” position, an “all ones” pattern is inserted into the data stream being transmitted out of the coax or twisted pair port on the 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. A blinking “Tst” LED on the remote T1/E1 shows confirmation that the Coax or UTP segment is communicating properly between the devices. By returning the DIP-switch to the “Norm” position, the unit resumes normal operation.

SW1 AND SW2 - AMI/B8ZS/HDB3 MODE

B8ZS (T1) or HDB3 (E1) is the default line encoding mode of operation. To select AMI mode enable both the Local Dual Loop-back “Loop” and Fiber Optic Test “FOT” DIP-switches on the front of the module.

PUSH BUTTON - MANUAL CROSSOVER “= / X”

The Manual Crossover “= / X” button located on the front panel is used to eliminate the need for crossover and custom cables when connecting devices to the RJ-45/48 port. When the button is in the out “=” position, the port is configured for a straight-through cable. When the button is in the in “X” position, the port is configured for a crossover cable. 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.

2) INSTALL STANDALONE MODULE AND CONNECT CABLES

a.The T1/E1 Converter is available in wall-mount models. For wall-mounting, attach the unit to a wall, backboard or other flat surfaces.

To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Then connect the barrel plug at the end of the wire on the AC/DC adapter to the 2.5mm DC barrel connector (center-positive) on the chassis. Confirm that the unit has powered up properly by checking the power status LED located on the front of the unit.

To power the unit using a DC power source, prepare a power cable using a two- conductor insulated wire (not supplied) with a 14 AWG gauge minimum. Cut the power cable to the length required. Strip approximately 3/8 of an inch of insulation from the power cable wires. Connect the power cables to the standalone unit by fastening the stripped ends to the DC power connector.

Connect the power wires to the DC power source. The Power LED should indicate the presence of power.

WARNING: Note the wire colors used in making the positive and negative connections. Use the same color assignment for the connection at the DC power source.

NOTE: If mounting with a safety ground attachment, use the safety ground screw at the rear of the unit.

b.When using the SFP model (8719-0 or 8759-0), insert the SFP Fiber transceiver into the Port 1 SFP receptacle on the T1/E1 converter (see the SFP Data Sheet 091-17000-001 for supported transceivers).

NOTE: The release latch of the SFP Fiber transceiver must be in the closed (up) position before insertion.
