16-Port Channelized E1/T1 Circuit Emulation MIC Overview

The Channelized E1/T1 Circuit Emulation MIC (MIC-3D-16CHE1-T1-CE) is a channelized MIC with 16 E1 or T1 ports. The following features are supported on this MIC:

  • Each MIC can be separately configured in either T1 or E1 framing mode.
  • Each T1 port supports the following framing modes:
    • Superframe (D4)
    • Extended superframe (ESF)
  • Each E1 port supports the following framing modes:
    • G704 with CRC4
    • G704 without CRC4
    • Unframed
  • Clear channel and NxDS0 channelization. For T1 the value of N ranges from 1 through 24 and for E1 the value of N ranges from 1 through 31.
  • Diagnostic features:
    • T1/E1
    • T1 facilities data link (FDL)
    • Channel service unit (CSU)
    • Bit error rate test (BERT)
    • Juniper Integrity Test (JIT)
  • T1/E1 alarm and performance monitoring (a Layer 1 OAM function)
  • External (loop) timing and internal (system) timing
  • TDM circuit emulation services CESoPSN and SAToP
  • CoS parity with IQE PICs. The CoS features supported on MPCs are supported on this MIC.
  • The following encapsulations are supported on this MIC:
    • ATM CCC cell relay
    • ATM CCC VC multiplex
    • ATM VC multiplex
    • Multilink Point-to-Point Protocol (MLPPP)
    • Multilink Frame Relay (MLFR) FRF.15
    • Multilink Frame Relay (MLFR) FRF.16
    • Point-to-Point Protocol (PPP)
    • Cisco High-Level Data Link Control
  • ATM class-of-service (CoS) features—traffic shaping, scheduling, and policing
  • ATM Operation, Administration, and Maintenance
  • Graceful Routing Engine switchover (GRES)
    • When GRES is enabled, clear statistics is performed and on initiating the Routing Engine switchover, the updated statistics is not reflected on the secondary Routing Engine.
    • ISSU is not supported on the 16-Port Channelized E1/T1 Circuit Emulation MIC (MIC-3D-16CHE1-T1-CE).
