Configuring T1/E1 Line-Build-Out (T1 Only); Configuring T1/E1 Used-Connector (E1 Only); Configuring T1/E1 Application Mode - Patton electronics SmartWare R.3.20 Software Configuration Manual

SmartWare Software Configuration Guide
The advantage of the unframed mode (obviously with hdlc encapsulation) is the utilization of the whole link
speed for user data transmission, 2.048MBit/s for E1 and 1.544MBit/s for T1. However note that HDLC has
its own overhead which decreases the actual data rate.

Configuring T1/E1 line-build-out (T1 only)
The line build out configuration is used in long haul applications to prevent cross talk in the far end device.

Configuring T1/E1 used-connector (E1 only)
If the T1/E1 WAN-Card provides several line interface connector types the command specifies which one is
currently in use. Sure, the signal is always on all connectors available but dependent on the wiring technology
the internal impedance matching must be adapted (RJ45 = 120 Ohm; BNC = 75 Ohm).

Configuring T1/E1 application mode
The T1/E1 port can be configured to work in either short-haul or in long-haul mode. Short-haul is the default
application and should be used for transmission distances up to 180m/600ft. For transmission distances up to
1800m/6000ft, select the long-haul application.
Mode: port e1t1 <slot> <port>
