Juniper Networks M20 - Manual (Page 9)

■ Multiprotocol Label Switching (MPLS) circuit cross-connect (CCC) for leveraging ATM
access networks
■ Support for user-configurable virtual circuits (VC) and virtual paths (VP)
■ ATM Inverse Address Resolution Protocol (ARP), which enables routers to automatically
learn the IP address of the router on the far end of an ATM permanent virtual circuit
(PVC)
■ Unspecified bit rate (UBR) traffic shaping
■ Fine-grained variable bit rate (VBR) traffic shaping
■ Outbound PIC queues cells on a per-VC basis
■ Encapsulations—AAL5 subnetwork attachment point (SNAP)
Software features
■ 10-ft (3.05-m) posilock SMB to BNC
■ Four pairs of RX and TX coaxial cables
Cables and connectors
One tricolor per port:
■ Off—Not enabled
■ Green—Online with no alarms or failures
■ Amber—Online with alarms for remote failures
■ Red—Active with a local alarm; router has detected a failure
LEDs
■ Alarm Indication Signal (AIS)
■ Frame Error
■ Line code violation
■ Local and remote loopback
■ Loss of Signal (LoS)
■ Out of Frame (OoF)
■ Yellow alarm
