16-Port Channelized E1/T1 Circuit Emulation MIC Overview

The Channelized E1/T1 Circuit Emulation MIC (ACX-MIC-16CHE1-T1-CE) is a channelized MIC with 16 E1/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

• ATM encapsulation—Only the following ATM encapsulations are supported on this MIC:

  • ATM CCC cell relay

  • ATM CCC VC multiplex

• ATM pseudowires

• ATM quality-of-service (QoS) features—traffic shaping, scheduling, and policing

• ATM Operation, Administration, and Maintenence

• ATM (IMA) protocol at the T1/E1 level with up to 4 IMA groups. Each group can have 1 to 8 IMA links.
