FlexPoint T1/E1 Copper to Fiber Line Driver

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 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.

Model #: Fiber Type: Max Distance:

MT660A-MM MM,ST,1300nm 5km / 3.1mi

MT661A-SM SM, ST, 1300nm 28km / 16.8mi

MT660A-MM-EMM,ST, 1300nm 5km / 3.1mi

MT661A-SM-ESM, ST, 1300nm 28km / 16.8mi

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 the supplied power unit.

3. Models shipped with international power supplies are capable of auto switching

form 100-230VAC, 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 320 appliance cable with a minimum rating of 10 AMPs.

5. User-supplied cables must meet the required safety agency approvals, applicable

international standards and electrical ratings for the region.

Warning!

Before inserting the Power Adapter, verify that the power

On the unit is appropriate for your AC line voltage source.

Mounting Instructions:

The Flex Point Fiber Converter can be solo-mounted using a wall-mounting kit, or rack-

mounted using a 5-unit shelf, or a high-density Flex Point 14-unit Power-Redundant

Chassis.

Fiber Optic Cable Attachment:

Connect the fiber cables between the Flex Point T1/E1 converters. The transmit (Tx)

must attach to the receive (Rx) side and the receive (Rx) side must attach to the transmit

(Tx) 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 Flex Point T1/E1 converter via a category 3 or

better cable (Category 5 is recommended) 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 Flex Point 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. Set this switch to DCE to use

a straight-through cable and to DTE when a crossover-cable would be required.

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 Flex Point T1/E1 media converter.

Operational Switch Settings and Functions:

The following operational switches located on the front of the Flex Point T1/E1 converter

are to assist in installation and fault isolation.

Local Loop-Back (L/LB)

This switch will set the Flex Point T1/E1 converter in a loop-back mode on both the fiber

and copper connections. By turning the switch to the normal position, the unit will

resume to normal operation.

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 Flex Point 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 Flex Point 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.

Remote loop-back (R+L/LB)

This switch will allow the entire fiber segment to be tested at either of the Flex Point

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 Flex

Point 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 Flex Point T1/E1 converters will show a

configuration that the fiber segment is communicating properly between devices. By

returning the switch to the normal position, it will resume to normal operation.

The Flex Point 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
