 Troubleshooting

First examine the backbone wiring pair and make sure you have solid connections. The

Interlink Sync LED will be lit solid Green with rapid pulsing on each 860 Pro unit to show proper

connection and pairing. If the Interlink Sync LED Link is flashing slow to fast and never goes

solid…. Then follow the steps below:

1) Make sure your wiring is straight through and not connected to any Telco punch

down blocks; If so remove from the block and use Telco butt clips to bridge wire.

2) Check for a firm connection of the RJ-45 connections in each 860 Pro unit, and

power is applied to the 860 Pro CO & CPE units.

3) You can easily isolate any issue by performing an Out Of The Box Test (OOTBT).

This test will confirm the correct working order of your Enable-IT 860 Pro

Ethernet Extender Kit. This will point to a possible issue with your long distance

Interlink wiring being affected by possible outside interference.

Performance Settings (DIP Switch)

If you are experiencing performance issues with your Ethernet connection you may use the

following DIP switch settings to adjust your application. For DIP switch 2-4 you must toggle

both symmetrically, in other words the CO and CPE must match. If you turn DIP switch 3 Up

(Off) on the CO, then you must do so for the CPE and vice-versa.

 Switch 1: CO / CPE Mode

CO Mode – Up / Off Position

CPE Mode – Down / On Position

Central Office Equipment (CO) is generally the equipment residing at the Carrier

Telephone office or the head end of a circuit. Customer Premise Equipment (CPE) is

generally the equipment residing on the customer side of a circuit. Typically you would

place the CO at the local end and the CPE at the remote end for reference only. CO’s only

communicate with CPE’s.

 Switch 2: Error Correction Mode

Interleaved Error Correction Enabled – Up / Off Position – degrades performance

Fast Channel – Down / On Position (Default)

Interleaved Error Correction works better for file transfers, where the delivered data must

be error free but latency incurred by the retransmission of error packets is acceptable. Fast

channel is preferred for streaming multimedia, where an occasional dropped bit is not

noticeable or acceptable.

 Switch 3: 17a (over 1,500ft) / 30a (under 1,500ft) Mode

17a Mode – Up / Off Position

30a Mode – Down / On Position (Default)

17a mode is only used for Interlink runs over 1,500ft to 6,000ft.

30a mode is only enabled for Interlink runs under 1,500ft.

 Switch 4: Signal-to-noise Noise Ratio (SNR)

9dB – Up / Off Position

6dB – Down / On Position (Default)

Signal-to-noise ratio is a measurement that refers to how much noise is in the output of a

device, in relation to the signal level. If you experience issues of noise bleeding over the

lines, or high interference in your environment, it is suggested that you switch to 6dB SNR.

This may help clean up any noise bleeding over your cabling.
