Channelized E1/T1 Enhanced IQ (IQE) PIC (M320 Router)

Software release

• Junos OS Release 9.5 and later (Type 1)

  For information on which FPCs support this PIC, see M320 PIC/FPC Compatibility.

Description

• Ten E1 or T1 ports

• DS1 and E1 interfaces are selectable on a per-port granularity

• E1 channelization per PIC:

  • 10 E1 channels

  • 310 DS0 channels

• T1 channelization per PIC:

  • 10 T1 channels

  • 240 DS0 channels

• Power requirement: 0.52 A @ 48 V (24.73 W)

• Model number: PB-10CHE1-T1-IQE-RJ48

Software features

• Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection (RED), weighted random early detection (WRED)

• Enhanced fine-grained queuing per logical interface. See the Class of Service Feature Guide for Routing Devices and EX9200 Switches for more information about class of service features.

• Support sending and receiving in-band loopback codes in both framed and unframed mode:

  • Framed in-band loopback at CSU

  • Framed in-band loopback at Smartjack (ANSI)

  • Unframed in-band loopback at CSU

  • Unframed in-band loopback at Smartjack (ANSI)

• You can configure the following framing modes using the CLI:

  • T1—SF (D4/superframe), ESF (extended superframe)

  • E1—G704, G704–no-crc4, unframed

• Packet buffering, Layer 2 parsing

• Local line, remote line, and remote payload loopback testing; each channel can be looped individually and independently of other channels (DS1/E1 channels)

• Simple Network Management Protocol (SNMP): T1 MIB (RFC 1406)

• Dynamic, arbitrary channel configuration

• Full bit error rate test (BERT)

• Clocking: internal and loop (clock recovered from network and use for transmit). Internal timing is the default for channelized T1 ports. The external master clock can be a multiple of 2.048 MHz or 1.544 MHz for E1 or T1 operation.

• Line coding:

  • T1—CLI configurable as AMI or B8ZS

  • E1—HDB3

• Encapsulations:

  • Circuit cross-connect (CCC)

  • Translational cross-connect (TCC)

  • Extended Frame Relay for CCC and TCC

  • Flexible Frame Relay

  • Frame Relay

  • Frame Relay for CCC

  • Frame Relay for TCC

  • Frame Relay port CCC

  • High-Level Data Link Control (HDLC)

  • HDLC framing for CCC

  • HDLC framing for TCC

  • MPLS CCC

  • MPLS TCC

  • Point-to-Point Protocol (PPP)

  • PPP for CCC

  • PPP for TCC

• Encapsulations available only for DS0 and DS1:

  • Multilink Frame Relay end-to-end (MLFR FRF.15)

  • Multilink Frame Relay (MLFR) UNI NNI (MFR FRF.16)

  • Multilink PPP (MLPPP)

• Encapsulations available only for DS1:

  • PPP over Frame Relay

LEDs

One tricolor per port:

• Off—Not enabled

• Green—Online with no alarms or failures

• Yellow—Online with alarms for remote failures

• Red—Active with a local alarm; router has detected a failure

Instrumentation (counters)

• Layer 2 per-queue and per-channel packet and byte counters

• Layer 2 per-queue and per-channel packet and byte drop counters
