This DIP-switch facilitates the testing of the coax cables. When the “CLB”
dip-switch is in the right position, it sets the coax port to a Local Coax
Loopback Mode (Figure 4) and the “CLB” LED is turned ON. When in this
mode, data received at the BNC-In is forwarded to the BNC-Out and the
Fiber-Out. If no data is received at BNC-In, an AIS pattern is transmitted
out both BNC-Out and Fiber-Out. By returning the DIP-switch to the left
position, the unit resumes normal operation.
The following DIP-switches are located on the front of the T3/E3 converter.
These switches provide data path control (normal operation and loop-
backs) and test patterns (all 1’s) that assist in installation and fault isolation.

When both the “FLB” and “CLB” DIP-switches are in the right position, they
force a remote unit to loop back its fiber and coax ports (Figure 5). This
facilitates test of the fiber cables and the remote unit without having to
physically set DIP-switches on the remote unit. While in this mode, the
local unit’s BNC is set to a local loopback, and its “FLB” and “CLB” LEDs
are turned ON.

The iConverter T3/E3 managed media converter is a member of the
modular iConverter product family. The T3/E3 provides standard T3
(B3ZS line protocol, 44.763Mbps) or E3 (HDB3 line protocol, 34.368Mbps)
coax to fiber conversion and can be used by telco service providers
and enterprise users to connect devices such as PBXs, multiplexers,
routers and video servers via multimode (MM), single-mode (SM) or
single-mode single-fiber (SF) fiber.
E3 is selected
when T3 and
STS-1 are OFF
For wide temperature (-40 to 60º C), add a "W" to the end of the model number.
Consult factory for extended temperature (-40 to 75º C) models.
When using single-fiber (SF) media converter models, the TX wavelength on one end
has to match the RX wavelength on the other.

While in the Remote Loopback Mode, the local unit sends a test pattern to
the remote unit. This pattern forces the remote unit into the loopback mode
and is also returned back to the local unit. When forced into the Remote
Loopback Mode, the remote unit’s “FLB” and “CLB” blink slowly (1Hz).

Designed to extend the standard T3/E3 Coax network distances over
fiber, this converter provides protection from environmental noise and
effectively increases high-speed network reliability.
This DIP-switch facilitates the testing of the fiber cables. When the “FLB”
dip-switch is in the right position, it sets the fiber port to a Local Fiber
Loopback Mode (Figure 3) and the “FLB” LED is turned ON. When in this
mode, data received at the Fiber-In is forwarded to the BNC-out and the
Fiber-Out. If no data is received at Fiber-In, an AIS pattern is transmitted
out both BNC-Out and Fiber-Out. By returning the DIP-switch to the left
position, the unit resumes normal operation.

When the test pattern is received successfully at the local unit’s Fiber-In,
the “TST” LED blinks rapidly (10Hz). Any other data causes slow “TST”
blinking (1Hz). If no data is returned to Fiber-In, the LED is turned OFF.

The T3/E3 can be used in a managed or unmanaged fashion. When
unmanaged, it can be installed in an iConverter chassis without a
Network Management Module (NMM). To be managed, a NMM module
must be installed in the same chassis as the T3/E3 module. To read
about specific management functionality, refer to the NetOutlook™

the module with the installation guides. Ensure that module is firmly
seated against the backplane.
2. Secure the module by securing the panel fastener screw (attached to
module) to chassis front.
3. When using an SFP model (8759-0), insert the SFP Fiber transceiver
into the SFP receptacle on the module.
Note: The release latch of the SFP Fiber transceiver must be in

to the Transmit.
5. When using a single-fiber models, you must use mating converters.
For example, if one converter is the model 8750-1 (TX=1310nm,
RX= 1550nm), the other converter must be model 8751-1 (TX=1550nm,
RX=1310nm).
6. Attach the BNC cables to the T3/E3 converter and attach the other
end of the cables to appropriate network equipment. The Transmit must
attach to the Receive and the Receive must attach to the Transmit.
