Page 2: Atm Terms And Acronyms
ATM Terms and Acronyms ATM Terms and Acronyms The following are common ATM terms and acronyms for your reference: AAL—ATM Adaptation Layer. An AAL defines the conversion of user information into cells. AAL1 and AAL2 handle isochronous traffic, such as voice and video; AAL3/4 and AAL5 pertain to data communications through the segmentation and reassembly of packets. -
Page 3: Asynchronous Transfer Mode Overview
Asynchronous Transfer Mode Overview SONET—Synchronous Optical Network. An ATM UNI specification and American National Standards Institute (ANSI) standard (T1.105-1988) for optical digital transmission at hierarchical rates from 51.840 Mbps (STS-N) to 2.5 Gbps and greater. SONET OC3—Optical Carrier-3 specification. SSCOP—Service Specific Connection Oriented Protocol. SSCOP Resides in the service specific convergence sublayer of the ATM adaptation layer. -
Page 4: Acip Description
ACIP Description An ATM connection transfers raw bits of information to a destination router/host. The ATM router takes the common part convergence sublayer (CPCS) frame, carves it up into 53-byte cells, and sends these cells to the destination router or host for reassembly. Forty-eight bytes of each cell are used for the CPCS data;... - Page 5 ACIP Interface The ACIP’s ATM interface is full duplex. You must use the appropriate ATM interface cable to connect the ACIP with external ATM equipment. (Refer to the section “ACIP Cables, PLIM, and Connections,” on page 7, for descriptions of ATM cables and connectors.) The ACIP provides an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps bidirectionally;...

Page 9: Acip Installation Prerequisites
ACIP Installation Prerequisites Before you begin the ACIP installation, review the guidelines in this section to ensure a successful installation, to avoid injuring yourself, or to avoid damaging the equipment. This section also provides a list of parts and tools you will need to perform the installation. ACIP Software Prerequisites To ensure correct operation of the ACIP, Cisco IOS Release 11.2(7)P or later is required. - Page 10 ACIP Installation Prerequisites Figure 7 shows the rear of the 7-slot Cisco 7507 router. In the Cisco 7507, up to two slots (2 and 3) are reserved for the Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 and 1, and 4 through 6 are for interface processors, including the ACIP.
- Page 11 Figure 8 shows the rear of the 13-slot Cisco 7513. In the Cisco 7513, up to two slots (6 and 7) are reserved for the Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 through 5, and 8 through 12 are for interface processors, including the ACIP.

RSP2s can be used with the ACIP. • The appropriate single-mode optical-fiber cable(s) with Simplex or Duplex connections (optical-fiber cables are not available from Cisco Systems; cables are available from commercial cable vendors) • Number 2 Phillips screwdriver or a 3/16-inch flat-blade screwdriver •... - Page 13 ACIP Installation Prerequisites Ce symbole d'avertissement indique un danger. Vous vous trouvez dans une situation Attention pouvant causer des blessures ou des dommages corporels. Avant de travailler sur un équipement, soyez conscient des dangers posés par les circuits électriques et familiarisez-vous avec les procédures couramment utilisées pour éviter les accidents.

Page 14: Preventing Electrostatic Discharge Damage
ACIP Installation Prerequisites Electrical Equipment Follow these basic guidelines when working with any electrical equipment: • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. • Disconnect all power and external cables before moving a chassis;... - Page 15 • When removing an ACIP, use the ejectors to release the bus connectors from the backplane. Hold the handle on the front of an ACIP with one hand and support the bottom edge of the metal carrier with the other hand. Pull the carrier out slowly, using your hand along the bottom of the carrier to guide an ACIP straight out of the slot.

Page 16: Installing And Removing An Acip
Installing and Removing an ACIP Installing and Removing an ACIP An ACIP slides into slots in the rear of a Cisco 7500 series chassis and connects directly to the backplane. The backplane slots are keyed so that the ACIP can be installed only in the slots designated for it. -
Page 17: Attaching Network Interface Cables To The Acip
Attaching Network Interface Cables to the ACIP The ACIP interfaces are full duplex. You must use the appropriate ATM interface cable to connect the ASIP to your TeraLink 1000, either directly, or through an external ATM network. Connect cables to the ACIP as shown in Figure 10. Figure 10 Connecting Cables to the ACIP (Vertical Orientation Shown) To a TeraLink 1000... - Page 18 Using LEDs to Check ACIP Status After you install the ACIP and attach the interface cable between the ACIP’s interface port and your cable headend (TeraLink 1000) or external ATM switch, verify the installation by observing the LED states and the console display. When the system has reinitialized all interfaces, the enabled LED on the ACIP should go on.

Page 21: Configuring The Acip
Configuring the ACIP Configuring the ACIP is a two step process: first you configure the ACIP, then you configure the cable headend and/or ATM switch. To configure ATM, complete the following tasks. The first two tasks are required, and then you must configure at least one PVC or SVC. The VC options you configure must match in three places: on the router, on the ATM switch, and at the remote end of the PVC or SVC connection. - Page 22 Configuring the ACIP Configure an ACIP Interface The ACIP interface (or subinterface) uses the configuration defaults shown in Table 1. For information on how to change the defaults, refer to the “Configuring ATM” chapter of the Wide-Area Networking Configuration Guide and the “Configuring Interfaces” chapter of the Configuration Fundamentals Configuration Guide.
- Page 23 Configure Cable Parameters To assign the ATM interface on the ACIP to a cable headend and specify the cable headend IP address, perform the following tasks beginning in global configuration mode: Task Step 1 Specify the ATM interface, VPI, and headend IP address.
- Page 24 Configuring the ACIP To create a bridge-group virtual interface, perform the following tasks in interface configuration mode: Task Enable a bridge-group virtual interface. Step 1 Step 2 Specify the IP address for the interface. Disable the sending of redirect messages. Step 3 Step 4 Optionally, enable fast-switching on the...

Monitor and Maintain the ACIP After configuring the new interface, you can display its status. You can also display the current status of connections and active modems on each interface. To show current status information, perform the following tasks in EXEC mode: Task Display the configured cable channels status. -
Page 26: Checking The Configuration
ACIP Error Statistics ACIP Error Statistics The ACIP maintains a count of certain errors. In addition to keeping a count of these errors, the ACIP also takes a snapshot of the last VCI/VPI that caused the error. Each ACIP error counter is 16 bits. Errors include the following: •... -

Page 28: Examples Of Atm Error Messages
Examples of ATM Error Messages • To display ATM events, use the debug atm events command: This command displays event changes to the ACIP. Reset, VC configurations, ACIP configurations, and PLIM failures are displayed. After you use a debug command, turn off debugging with the no debug command. Following are additional debug commands specifically related to the ACIP: •... - Page 29 Error Message AIP_love_note(ATM2/0): asr=0xaaaa Received a love note from the ACIP. Love notes are messages that the ACIP passes to Explanation the RSP to indicate an action or event has taken place. For example, the ACIP signals the RSP with a love note when the ACIP completes a VC setup/teardown request.
- Page 30 Examples of ATM Error Messages Following is a list of possible error messages displayed when you enter the debug atm errors command: Error Message AIP_love_note(ATM2/0): UNKNOWN asr=0x0000 Explanation Error Message AIP_setup_vc(ATM2/0): TIQ err.
