The single-mode transmitter in the ATM CES port adapter uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it.
Here is an example of the laser warning label that appears on the product:
 | Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode ATM CES port adapter when no fiber cable is connected. Avoid exposure and do not stare into open apertures. |
| Warning Class 1 laser product. |
Follow these basic guidelines when working with any electrical equipment:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
 | Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm). |
The ATM CES port adapter has 13 LEDs that indicate the status of the port adapter, the status of the uplink ports, and the status of the CBR ports. (See Figure 2-1 and Figure 2-2.)
Table 2-2 describes the LED that indicates port adapter status.
| Name | Color | State | Description |
|---|---|---|---|
Enabled | Green | On | Indicates that the port adapter is ready. |
After system initialization, the enabled LED goes on to indicate that the port adapter has been enabled for operation.
The following conditions must be met before the ATM CES port adapter is enabled:
If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not go on.
Table 2-3 describes the LEDs that indicate uplink port status.
| Name | Color | State | Description |
|---|---|---|---|
RCLK | Green | On | Indicates that a receive clock was detected. |
FERF | Yellow | On | Indicates that Framer detected Far End Receive Failure. |
OOF | Yellow | On | Indicates that Framer detected Out of Frame. |
AIS | Yellow | On | Indicates that Framer detected Alarm Indication Signal. |
Table 2-4 describes the LEDs that indicate CBR port status. There are four Enabled and four Alarm LEDs, one for each port.
.
| Enable LED State | Alarm LED State | Description |
|---|---|---|

On (green) | On (yellow) | Red alarm condition |
Cables on the ATM CES port adapter fall into two categories:
ATM CES port adapter interfaces are full-duplex. You must use the appropriate ATM interface cable and CBR cable to connect the ATM CES port adapter with an external ATM network. The ATM CES port adapters, shown in Figure 1-1 and Figure 1-2, provides an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps bidirectionally for OC-3, 44.736 Mbps bidirectionally for DS3 over T3, and 34 Mbps bidirectionally for E3.
Cables can be obtained from the following cable vendors:
Two types of cables are available for use with the ATM CES port adapter's OC-3 and T3/E3 ATM ports:
Both ATM cables conform to the EIA/TIA-612 and EIA/TIA-613 specifications. The ATM port on the ATM CES port adapter is a DTE device.
For OC-3 single-mode, the ATM CES port adapter connects to the SONET/SDH 155-Mbps single-mode optical fiber physical layer, either STS-3C or STM-1. The connection is made by means of single-mode OC-3 ATM cables with SC connectors (see Figure 2-3). The SONET single-mode SC connector is shipped with removable dust covers on each SC connector. Keep covers on any connectors that are not being used.
For SONET/STC-3C single-mode connections, use one duplex SC connector (see Figure 2-3) or two single SC connectors (see Figure 2-4).
For T3/E3 connections, use a 75-ohm coaxial interface cable (see Figure 2-5). The T3/E3 75-ohm coaxial cable is available from Cisco in five different lengths: 10, 25, 50, 75, and 100 feet. They are not available from outside commercial vendors. The typical maximum distance between stations for T3 transmissions is 450 feet (135 meters) and for E3 transmissions is 1300 feet (390 meters).
The T3/E3 line interface performs physical layer translation from the ATM CES port adapter to the T3/E3 line interface in accordance with ATM Forum UNI specification Version 3.1, ACCUNET T45 service specifications, and ANSI T1E1.107.
The four CBR interface receptacles on the ATM CES port adapter are RJ-48C for T1 and E1 (120 ohm). Each connection supports T1 or E1 (120-ohm) interfaces that meet T1E1.403 and ACCUNET TR62411 standards. The RJ-48C connection does not require an external transceiver. The CBR ports are T1 interfaces that use UTP, 100-ohm twisted pair cables and E1 interfaces that use UTP, 120-ohm twisted pair cables (see Figure 2-6). The typical maximum distance between stations for T1 and E1 transmissions is 1000 feet (300 meters).
Table 2-5 lists the pinouts and signal descriptions for the CBR RJ-48C connector.
| Pin | Signal1 |
|---|---|
1 | Rx ring |
2 | Rx tip |
3 | NC |
4 | Tx ring |
5 | Tx tip |
6 | NC |
7 | NC |
8 | NC |
| 1Tx = transmit. Rx = receive. NC = no connect. |
