• The following loopback tests are supported:
– Network (line) loopback
– Internal (diagnostic) loopback
• Supported SONET/SDH synchronization:
– Local (internal) timing (for inter-router connections over dark fiber or wavelength division
multiplexing [WDM] equipment)
– Loop (line) timing (for connecting to SONET/SDH equipment)

Layer 2 Features
• Supports the following encapsulation types:
– AAL5SNAP (LLC/SNAP)
– AAL5MUX (VC multiplexing)
– AAL5NLPID
• Supports the following ATM traffic classes and per-VC traffic shaping modes:
– Constant bit rate (CBR) with peak rate
– Unspecified bit rate (UBR) with peak cell rate (PCR)
– Non-real-time variable bit rate (VBR-nrt)
– Variable bit rate real-time (VBR-rt)
Note ATM shaping is supported, but class queue-based shaping is not.
• ATM multipoint connections (beginning in Cisco IOS XE Release 2.5)
• ATM point-to-point connections
