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.
NOTE: ACX5048 and ACX5096 routers do not support T1/E1 interfaces and
related features.
