This chapter briefly describes the ATM port adapters supported by the following systems:
Features common to these port adapters as well as features specific to each adapter are described in the following sections:
ATM port adapters provide ports for connection to network services.You can install up to two port adapter cards in a carrier module in slot 0, slot 1, slot 3, or slot 4 of an ATM switch chassis. Slot 2 is reserved for the processor card.
Figure 1-1 shows an ATM port adapter.
The ports on each adapter can be configured as redundant links using the ATM switch routing protocols. Each port has receive and transmit LEDs that provide port status and operation information.
ATM port adapters share the following common features:
Each interface (or port) in the switch is designated by several different types of addresses. The physical interface address is the actual physical location (card/subcard/port) of the interface connector within the chassis. The system software uses the physical addresses to control activity within the switch and to display status information. These physical card/subcard/port addresses are not used by other devices in the network; they are specific to the individual switch and its internal components and software.
In the ATM switch, port IDs specify the actual physical location of each port on the front of the switch. (See Figure 1-2.) The address is composed of a three-part number in the format card/subcard/port.
The first number identifies the slot in which the module is installed. Module slots are numbered 0 to 4 from top to bottom. The second number identifies the subcard or port adapter number. The port adapters are numbered 0 and 1, with 0 being the left port adapter facing the front of the switch. The third number identifies the physical port number on the module. The port numbers always begin at 0 and are numbered from the left port to the right port, facing the front of the switch. The number of additional ports (/1, /2, and so on) depends on the number of ports available on the module.
Interface ports maintain the same port ID regardless of whether other modules are installed or removed. However, when you move a module to a different slot, the first number in the address changes to reflect the new slot number.
For example, on a four-port 155-Mbps UTP port adapter in chassis slot 1 in port adapter slot 0, the address of the left port is 1/0/0 and the address of the right port is 1/0/3. If you remove the four-port 155-Mbps UTP port adapter from slot 1 and install it in slot 4, the addresses of those same ports become 4/0/0 and 4/0/3.
You can identify module ports by physically checking the card/subcard/port location on the front of the switch. You can also use software commands to display information about a specific interface, or all interfaces, in the switch. To display information about every interface, use the show interface command without parameters. To display information about a specific interface, use the show interface command with the interface type and port address in the format show interface atm card/subcard/port. This command is described in your command reference publication.
Each port on the ATM port adapters can be configured to support the following clocking options:
Traffic pacing allows you to set the aggregate output traffic rate on any port to a rate below the line rate. This feature is useful when communicating with a slow receiver or when connected to public networks with peak-rate tariffs.
Supported ATM port adapters are described in the following sections:
The ATM switch supports any port adapter combination required, up to a maximum of 32 155-Mbps interface ports.

The 622-Mbps port adapter has a single port that provides the following ATM connections, as shown in Figure 1-6:
The ATM switch supports any port adapter combination required, up to a maximum of 32 DS3 or E3 interface ports.
Figure 1-7 shows a DS3 port adapter with BNC connectors.
The DS3 and E3 port adapters can provide intercampus and enterprise WAN connections, as shown in Figure 1-8 .
The DS3 can also be used to link a router at a customer site to a central office, as shown in Figure 1-9.
The DS3 can also be used to link an ATM switch at a customer site to a central office via a virtual path tunnel, as shown in Figure 1-10.
The DS3 port adapter meets Japan Approvals Institute for Telecommunications Equipment (JATE) approval. See Table 1-1 for JATE approval details for the DS3 port adapter.
