Black Box MT660A-MM MM - Manual

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.

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.

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.

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 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

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 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
s p e c i f i c a t i o n s t h a t a r e o u t l i n e d i n c o p p e r c a b l e
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
s p e c i f i c a t i o n s t h a t a r e o u t l i n e d i n c o p p e r c a b l e
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 FlexPoint T1/E1
media converter.

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. 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.
