### T1/E1 Cable

Notes:

1) The maximum recommended cable length for a T1/E1 cable is 655 feet (approximately 200 M) .

2) To connect the shielded connector to the shielded cable, the wire inside the cable’s metal sheath must be soldered to the metal case of the connector.

3) When Installing the connector and weatherseal strain relief onto cable, do not tighten to
the cable until final installation.

4) Connect to the T1 circuits using properly shielded 8-pin modular (RJ-48C) connectors; connect to the E1 circuits using properly shielded 8-pin modular (RJ-45) connectors.

For the Tsunami QuickBridge 20/60 and the Tsunami Multipoint SU 20/60, the color code of the Ethernet cable used between the power supply and the QB/SU was changed to the standard EIR 568B wiring color code.

Normally this does not present a problem since the cable is wired the same end-for-end; just the colors have changed. When using a lightning protector, however, the color code of the cable must be noted to make sure that the lightning protection is connected properly. Incorrect wiring can cause damage to the lightning protector. Here are the two different color codes.

Signal | RJ45 Pin# | DIN Pin# | Original Wiring Color | 538B Wiring Color
Tx+ | 1 | 5 | Green | White / Orange
Tx- | 2 | 3 | White / Green | Orange
Rx+ | 3 | 1 | Blue | White / Green
+V | 4 | 2 | Orange | Blue
-V | 5 | 7 | White / Orange | White / Blue
Rx- | 6 | 4 | White / Blue | Green
+V | 7 | 6 | Brown | White / Brown
-V | 8 | 8 | White / Brown | Brown

The color code that a cable is using can be identified by either looking at the color of the wire in pin one of the RJ45 connector (the pin on the left with the tab facing down and the cable coming towards you). If the wire in pin 1 is Green, then you have the original color code, if the wire is White / Orange then you have an EIA 568B wired cable.

Alternatively, if you do not have access to the RJ45 (for installed systems), you may reference the part number and revision label on the cable that is usually near the DIN connector. Refer to the following table to determine which color code cable you have based on the cable.
