PA-A6 ATM Port Adapter Installation and Configuration

OL-2672-05

Chapter 1 Overview

Cables and Connectors

The PA-A6 interfaces are full duplex. You must use the appropriate ATM interface cable to connect the

PA-A6 with an external ATM network.

Table 1-3 summarizes the PA-A6 interface types, connectors, and cables.

Note The PA-A6 is considered an ATM end-point device.

OC-3c Multimode and Single-Mode Cables and Connectors

The OC-3c port on the PA-A6 is considered a DTE device.

For SONET/SDH multimode and SONET/SDH single-mode connections, use one duplex SC connector

(see Figure 1-7) or two simplex SC connectors (see Figure 1-8). These cables are not available from

Cisco.

Note For information on SONET specifications for fiber-optic transmissions, understanding power budget,

and assistance with approximating the power margin for multimode and single-mode transmissions, see

the “Additional Information” section on page 1-7.
