Cabling and Specifications
Step 2 Attach the line card cable-management bracket to the line card as follows:
a.Position the cable-management bracket over the front of the line card faceplate.
b.Insert and tighten the captive screw(s) to secure the bracket to the line card.
c.Starting with the bottom port on the line card, connect each interface cable to the intended port.
Step 3 For multiport line card cable-management brackets, carefully wrap the cables with the supplied Velcro strap. (See Figure 13.)
For single-port line card cable-management brackets, carefully press the interface cable onto the cable clip. (See Figure 14.) Avoid any kinks or sharp bends in the cable.

ATM Line Card Power Budget and Signal Specifications
The 4-port ISE ATM line card uses both single-mode and multimode fiber-optic cable. Signals can travel farther through single-mode fiber than through multimode fiber. The maximum distance for installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distances, you should use an optical time domain reflectometer (OTDR) to measure the power loss.

1-port OC-12c/STM-4c ATM Line Card Power Specifications
The 1-port OC-12c/STM-4c ATM line card provides the Cisco 12000 series router with a single
622-Mbps ATM interface. Table 4 lists the power ratings and distances of the interface. The distance in a given case depends on the quality of the fiber attached to the transceiver.
