6 Asynchronous Transfer Mode Interface Processor (AIP) Installation and Configuration
AIP Interface Types
•
Both AAL5 and AAL3/4.
Note
AAL3/4 is supported as of Cisco IOS Release 10.2 and later.
•
Exception queue, which is used for event reporting. Events such as CRC errors are reported to
the exception queue.
•
Raw queue, which is used for all raw traffic over the ATM network. Raw traffic includes
Operation, Administration, and Maintenance (OAM) cells and Interim Local Management
Interface (ILMI) cells. (ATM signaling cells are not considered raw.)
•
MIB attributes, which are readable and writable across the ILMI using a Simple Network
Management Protocol (SNMP). The ATM UNI specification defines the required MIB
functionality for ATM interfaces. The ILMI uses SNMP, without UDP, and Internet Protocol (IP)
addressing along with the ATM MIB.
•
RFC 1213 interface MIBs as specified in the ATM MIB V2 specification. (Refer to the ATM UNI
specification for additional details of the MIB.)
AIP Interface Types
All AIP ATM interfaces are full-duplex. You must use the appropriate ATM interface cable to
connect the AIP with an external ATM network. Refer to the section “AIP Installation Prerequisites,”
on page 7, for descriptions of ATM connectors.
The AIP provides an interface to ATM switching fabrics for transmitting and receiving data at rates
of up to 155 Mbps bidirectionally; the actual rate is determined by the PLIM.
The AIP supports PLIMs that connect to the following physical layers (with product numbers
included):
•
TAXI 4B/5B 100-Mbps multimode (CX-AIP-TM[=])
•
SONET/SDH 155-Mbps multimode—STS-3 or STM-1 (CX-AIP-SM[=])
•
SONET/SDH 155-Mbps single-mode—STS-3 or STM-1 (CX-AIP-SS[=])
•
E3 34 Mbps (CX-AIP-E3[=])
•
DS3 45 Mbps (CX-AIP-DS3[=])
The E3 and DS3 PLIMs require cable CAB-ATM-DS3/E3. To ensure compliance with EMI
standards, the E3 PLIM connection requires an EMI filter clip (CLIP-E3-EMI) on the receive
port (RCVR).
For wide-area networking, ATM is currently being standardized for use in Broadband Integrated
Services Digital Networks (BISDNs) by the International Telecommunications Union
Telecommunication Standardization Sector (ITU-T) and the American National Standards Institute
(ANSI). BISDN supports rates from E3 (34 Mbps) to multiple gigabits per second (Gbps).
The DS3 interface performs physical layer translation from the AIP to a DS3 line interface in
accordance with ATM Forum UNI Specification Version 3.1, ACCUNET T45 service specifications,
and ANSI T1.107.
