Juniper Networks M7I - Manual (Page 63)

• PIC can be configured as twelve T1 ports or twelve E1 ports
• Local and remote loopback diagnostics
• E1 ports
• High-performance throughput on each port at speeds up to 2048 Mbps, full duplex
• HDB3 line encoding
• Integrated support for G.704 framed mode with CRC; this feature is user-configurable
NOTE: The G.704 implementation supports speeds slower than 2.048 Mbps; multiple channels
within a single E1 interface are not supported.
• G.704 framed without CRC4
• Unframed
• Framed clear channel mode
• Unframed clear channel mode
• Framed fractional mode
• T1 ports
• High-performance throughput on each port at speeds up to 1544 Mbps, full duplex
• AMI and B8ZS line encoding
• Framed clear channel mode
• Fractional mode
• Superframe (D4/SF) and extended superframe (ESF) framing
• ESF CSU counters, WRT impairments, and CRC checking
• Local DS1 line loopback, remote line loopback
• Loop timing and PIC line timing
• Encapsulations: Structure-agnostic time-division multiplexing (TDM) over packet (SAToP)
(RFC 4553)
• Pseudowire emulation edge-to-edge (PWE3) for ATM (RFC 4717) (Junos OS Release 9.6 and
later)
• ATM Pseudowire emulation edge-to-edge via dynamic labels (LDP, RSVP-TE) (Junos OS
Release 9.6 and later)
• Inverse mulitplexing (IMA) for ATM (Junos OS Release 10.0 and later)
• Simple Network Management Protocol (SNMP): ATM MIB (Junos OS Release 10.2 and later)
• ATM QoS (Junos OS Release 10.2 and later)
• Per-virtual circuit (VC) and per-virtual path (VP) traffic shaping
• Unspecified bit rate (UBR) traffic shaping
• Fine-grained real-time variable bit rate (rtVBR) and real-time variable bit rate (nrtVBR)
traffic shaping
• Port-level egress shaping
• Constant bit rate (CBR)
• Policing on a per virtual circuit basis
• Independent peak cell rate (PCR) and sustained cell rate (SCR) policing
• Counting, tagging, or discard policing actions
Software features
• RJ-21 connector
• Cables are rated for intra-building connections only.
