1 CHAPTER This chapter describes the PA-A-IMA port adapter and contains the following sections: Port Adapter, page - Inverse Multiplexing over ATM, page - Features, page - LEDs, page - Cables, Connectors, and Pinouts, page - Port Adapter Slot Locations on the Supported Platforms, page - Identifying Interface Addresses, page - Port Adapter The PA-A-IMA (see Figure - and Figure -) is a single-width port adapter that allows the Cisco series routers, Cisco series routers, Cisco VXR routers, Cisco router, Cisco router, Cisco PCI Port Adapter Carrier Card in the Cisco router, Cisco ASR routes, Cisco series routers, and Catalyst family switches and Cisco series routers with a FlexWAN module to support inverse multiplexing over ATM. The PA-A-IMA supports data rates between DS and DS levels, or E and E levels, by combining the bandwidth of multiple DS or E links into groups that collectively provide higher intermediate rates. This Peripheral Component Interconnect (PCI)-based port adapter is available in a T version (PA-A-8T IMA) and an E version (PA-A-8E IMA). Note PA-A-8E IMA is not supported on Cisco ASR routers. Note To allow a full view of the port adapter faceplate detail, port adapter handles are not shown in Figure - and Figure -. -

2 Chapter Inverse Multiplexing over ATM Figure - PA-A-8T IMA Faceplate View ALRM T IMA BN 8 Figure - PA-A-8E IMA Faceplate View ALRM E IMA BN 8 The PA-A-IMA can be installed in a Cisco series router, Cisco series router, Cisco VXR router, Cisco router, Cisco router, Cisco PCI Port Adapter Carrier Card in the Cisco router, Cisco ASR router, VIP for Cisco series routers, or Catalyst family FlexWAN module for the Catalyst family switches and Cisco series routers. See the Port Adapter Slot Locations on the Supported Platforms section on page - for the available slot locations. Inverse Multiplexing over ATM Inverse multiplexing (IMA) provides a means of access to ATM networks at rates between DS/E and DS/E levels (. Mbps/.8 Mbps to. Mbps/.8 Mbps) by combining the bandwidth of multiple DS/E links into groups that collectively provide higher intermediate rates. These multiple links are especially desirable in networks where DS/E links are scarce. IMA breaks up the ATM cell stream and distributes the cells over the multiple physical links of an IMA group (inverse multiplexing) and then recombines the cells into a single stream at the other end of the connection. The ATM cells are distributed in a round-robin fashion over the physical links of the IMA group, demultiplexed at the receiving IMA group, and passed in their original form to the ATM layer (see Figure -). Using the multiple links of an IMA group increases the logical link bandwidth to approximately the sum of the individual link rates. -

4 Chapter LEDs These QoS classes: UBR (unspecified bit rate) VBR (variable bit rate) ABR (available bit rate) LEDs The PA-A-IMA has ten LEDs: one bicolor alarm LED, one green LED, and eight bicolor port status LEDs (see Figure -). Figure - PA-A-IMA LEDs ALRM E IMA BN 8 After system initialization, the LED goes on to indicate that the port adapter has been enabled for operation. The following conditions must be met before the PA-A-IMA is enabled: The PA-A-IMA is correctly connected and is receiving power. A valid system software image for the port adapter has been downloaded successfully. The system recognizes the PA-A-IMA, a VIP with a PA-A-IMA, or a Catalyst family switch or Cisco series Router with a FlexWAN module with a PA-A-IMA. If any of the above conditions are not met, or if the initialization fails for other reasons, the LED does not go on. Table - lists LED colors and indications. Table - PA-A-IMA LEDs LED Label Color State Function ALRM Yellow On Indicates a minor alarm on one of the T/E ports Red On Indicates a major alarm on one of the T/E ports Green On Indicates IMA port adapter is enabled for operation Port Green On Indicates port is enabled and in frame Green/Yellow Off Indicates port is not initialized or is in alarm condition Yellow On Indicates port is in loopback -

5 Cables, Connectors, and Pinouts Chapter Cables, Connectors, and Pinouts The eight DS/E interface receptacles on the PA-A-IMA are RJ- connectors for T ( ohm) or E ( ohm). All eight may be used simultaneously as ATM interfaces, or they may be used to create IMA groups. Note After you properly connect a port to a line, it takes approximately seconds for Cisco IOS software to report that the line is up. Each connection supports T (-ohm) or E (-ohm) interfaces that meet T. and ACCUNET TR standards. The RJ- connection does not require an external transceiver. The DS ports are T interfaces that use foil twisted-pair (FTP) cables. Note To meet VCCI Class II EMI requirements, you must use FTP cables. Figure - shows the PA-A-IMA interface cable connector. See Chapter, Configuring the PA-A-IMA, for directions on connecting the cables of an IMA group.

13 Identifying Interface Addresses Chapter Identifying Interface Addresses This section describes how to identify interface addresses for the PA-A-IMA in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch. Interfaces on a PA-A-IMA installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number. Interfaces on a PA-A-IMA installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move a VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot. Note Interface ports are numbered from left to right starting with.
