Configurable HDLC Parameters

Configuring Channelized T3 Interfaces

12
DS3/DS1 line status/alarm monitoring
DS1 line coding type—Both AMI line encoding and B8ZS line encoding
Unique IP interface support—For each PPP or Frame Relay PVC interface
The following HDLC parameters are configurable:
Mapping of DS0 timeslots for T1/FT1 DS0 mapping
Setting the speed of the DS0 to Nx56 or Nx64
HDLC CRC checking (enable/disable)
HDLC CRC algorithm (CRC16 or CRC32)
Channel data inversion (enable/disable)
Maximum receive unit (MRU)
Maximum transmit unit (MTU)
Statistics are also gathered per line module.
There12 T3 controllers available on each CT3 12-F0 line module. When you configure
these T3 controllers, you are actually configuring T3 (DS3) lines. Each T3 controller has,
by definition, 28 T1 controllers representing T1 (DS1) lines.
Use the T3 and T1 commands described in JunosE Physical Layer Configuration Guide, to:
Specify the line characteristics, such as framing format and clock source, for T3s and
associated T1s.
Assign full and fractional T1 channels (DS0) to a virtual channel.
Figure 5 on page 12 shows sample parameters for a channelized T3 interface
configuration.
