Here is my quick reference note for configuring a T3 interface on Juniper routers. Not part of my GWGK materials but as reminder again.

T3 is the physical layer protocol used by the Digital Signal level 3 (DS-3) multiplexing method in North America. A T3 interface operates at a bit rate of 44.736 Mbps. The JUNOS software supports payload scrambling and subrate operation on each physical T3 interface. One encapsulation format, PPP, Frame Relay, or HDLC, must be configured for the interface.

Important Links from Juniper:

• Configure T3 Interfaces
• Configure T3 BERT Properties
• Disable T3 C-Bit Parity Mode
• Configure the T3 CSU Compatibility Mode
• Configure the T3 Frame Checksum
• Configure the T3 FEAC Response
• Configure the T3 Idle Cycle Flag
• Configure the T3 Line Buildout
• Configure the Channelized T3 Loop Timing
• Configure T3 Loopback Capability
• Configure T3 HDLC Payload Scrambling
• Configure the T3 Start End Flags
