Chapter 3: Installation/Basic Troubleshooting
Preparing the Single-ended or Double-ended Telco Cable
Depending on your order, you will have received either a double-ended or a single-ended 50-pin
Telco cable. Follow these steps for preparing and installing the cables.
Single-ended 50-pin Cable
If you have ordered a single-ended shielded 50-pin Telco cable, you must prepare it for use with
your specific application.
At the opposite end from the 50-pin connector, the cable is taped off. Follow this procedure.
1. Cut into the outer cable casing approximately two inches from the taped off end, and cut lengthwise
toward the taped end of the cable. Spread the outer casing to expose the following elements:
• foil shielding, containing the bundle of 25 twisted pairs
• silver braided drain lead
• silk cords

2. Gather the silk cords and pull back along the cut end of the casing to expose the desired length.
3. Trim back the outer casing, the foil shielding, and the silk cords to fully expose the 25 twisted pairs.
4. Cut the drain lead and twisted pairs past the point of the initial cut into the cable casing. This will prevent
the use of any wires that may have been nicked in the initial cut.
5. Terminate the drain lead to an appropriate earth ground.
6. Terminate the twisted pairs to the customer-specific connections (see Figure 2-4 for the color-coded 50-pin
cable specification).
7. Secure the connector end with grounding shield to the appropriate point on the Tenor AX, making sure to
torque the strain relief screws to 4.5 - 5.0 in. lbs. (0.51- 0.57 Nm).
