FRONT PANEL DIP-SWITCH SETTINGS:	“CLB” DIP-Switch - Local Coax Mode Operation (Coax Loopback):
The following DIP-switches are located on the front of the T3/E3 converter.	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

	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.

“FAIS” Force AIS to Fiber (Force 1’s to Fiber):

When the “FAIS” dip-switch is in the right position, an “all ones” pattern is forced out the Fiber-Out port. The Coax-In data is discarded and Fiber-In data is passed through to BNC-Out. By returning the dip-switch to the left position, the unit resumes normal operation.

“CAIS” Force AIS to Coax (Force 1’s to Coax):

When the “CAIS” dip-switch is in the right position, an “all ones” pattern is forced out the BNC-Out port. The Fiber-In data is discarded and BNC-In data is passed through to Fiber-Out. By returning the dip-switch to the left position, the unit resumes normal operation.

OVERVIEW:

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.

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.

The T3/E3 module can be used in any of the iConverter chassis such as the 1-Module, 2-Module, 5-Module and 19-Module chassis.

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™ user manual T3/E3 section.

This User Manual covers the models listed in the following table.

The On Board DIP-switches facilitate the selection between T3, E3, STS-1 protocols, the coax distance, fiber and coax port control and the injection of pseudo random data patterns into the coax.

Fig. 6 Board Mounted DIP-Switches “T3” “E3” and “STS-1” DIP-Switches - Select Protocol:

When the “T3” DIP-switch is in the right position, the T3 protocol is selected. When the “E3” DIP-switch is in the right position, the E3 protocol is selected. When the “STS-1” DIP-switch is in the right position, the STS-1 protocol is selected. Only one of the three DIP-switches may be in the right position at any one time. The default setting of the module has no mode selected (the module will default to E3 mode with no switches set).

“<225/>225” Coax Build-Out Distance selection:

When this DIP-switch is in the left position, a distance of less than 225 ft. is selected. When in the right position, a distance of 225 ft. or higher is selected. Select the appropriate distance for your application.

“CEN/CDIS” and “FEN/FDIS” Port Control DIP-Switches:

When both DIP-switches are in the left position, the ports are enabled. When the “CEN/CDIS” is in the right position, the coax port is disabled. When the “FEN/FDIS” is in the right position, the fiber port is disabled.

“PRBS” Pseudo Random Pattern Generator Control DIP-Switch: When in the right position, the converter forces Pseudo Random pattern out of the Coax-Out port. The data received at Fiber-In is discarded and the data at Coax-In is passed through to Fiber-Out.

Note: Some combinations of DIP-switch settings are illegal, and will be indicated by the Fiber Test “TST” LED blinking quickly three times followed by a pause.

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.

*See SFP data sheet under Fast Ethernet for supported transceiver models.

Normal Mode Operation (Straight Through):

The default DIP-switch setting (all dip-switches to the left) sets the converter to its Normal Mode and allows data to flow straight through between the BNC and Fiber ports (Figure 2).

Fig. 2 Normal Mode and DIP-Switch Settings

“FLB” Dip-Switch - Local Fiber Mode Operation (Fiber Loopback):

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.

Fig. 4 Coax Loopback and DIP-Switch Settings Remote Loopback Mode:

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.

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).

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.

Returning both dip-switches to the left position, causes the local and remote units to resume normal operation.

MOUNTING INSTRUCTIONS and CABLE ATTACHMENTS:

iConverter modules are hot-swappable and can be installed into any chassis in the iConverter family.

1.Carefully slide the iConverter module into the installation slot, aligning 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 the closed position before insertion.

4.Connect the fiber cables between the T3/E3 converters. The Transmit (TX) must attach to the Receive (RX) and the Receive must attach 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.
