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:
Extended superframe (ESF)
Each E1 port supports the following framing modes:
G704 with CRC4
G704 without CRC4
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.
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 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.
ACX5048 and ACX5096 routers do not support T1/E1 interfaces and related features.
