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.
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.

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).

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.

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”

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.
