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/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.
- Graceful Routing Engine switchover (GRES)
- When GRES is enabled, clear statistics is performed and on initiating the Routing Engine switchover, the updated statistics will not be reflected on the secondary RE.
- ISSU is not supported on 16-Port Channelized E1/T1 Circuit Emulation MIC (MIC-3D-16CHE1-T1-CE).
