FlexPointTM T1/E1 Copper to Fiber

Converters

User Instructions

Description:

The FlexPoint T1/E1 connects T1 and E1 devices, such as
PBXs, CSUs and routers, via multimode (MM) or single-mode
(SM) fiber. Designed to extend the standard T1/E1 twisted p air
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.

Model # Fiber Type Max Distance

4470/90-x MM, SC, 1310nm 5km
4471/91-x SM, SC, 1310nm 30km

Power Adapter Notice

1. 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 Omnitron
Supplied Power Unit model numbers 9113-PS or 91 15-PS.

WARNING!

Before inserting the Power Adapter, verify that the

power on the unit is appropriate for your AC line

voltage source.

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.

Note: Use copper cables that are compliant with the
specifications that are outlined in copper cable specifications.

Coax E1 Connector

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.

Switch Settings:

UTP DCE/DTE setting

The UTP DCE/DTE switch is used to eliminate the need for
crossover and custom cables to connect devices together when
using the RJ-45/48 port. Se t th is s wit ch t o DC E to u se a
straight-through cable and to DTE when a crossover-cable
would be required.

Operational switch settings and functions

The following operational switches located on the front of
the FlexPoint T1/E1 converter are to assist in installation
and fault isolation.

Local Dual Loop Back

Normal

Remote & Local Loop Back
Force 1’s to Fiber
Force 1’s Copper

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

Cu-Tx

Loopback Enabled

FO-Tx

FO-Rx

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 the
local unit is switched to a local loop-back mode. The fiber
Tx port will be further encoded to carry a remote loop-back
protocol. This remote loop-back will set the far end
FlexPoint T1/E1 converter to remote loop-back mode 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 return to normal operation.

Local loop-back and Remote loop-back

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.

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.

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. Dat a 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 features dry relay contacts for
optionally connecting the it 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.
