Rate

The rate field allows selecting the DTE interface line rate. The rate can be set to
2.4, 4.8, 9.6, 19.2, 31.2, 38.4, 52, 56, 57.6, 60, and 64 kbps depending on the DDS
mode, DTE mode, and DTE format.

Interface

This field allows selecting the interface for Port A as V.35, RS-232, or EIA-530.

DSR

Data Set Ready is output from the unit to the DTE. Its behavior can be set to
TEST>OFF where DSR is On except when the unit is in test or set to Force On all
the time regardless of any unit condition.

DCD

Data Carrier Detect is output from the unit to the DTE. Its behavior can be set to
one of the following.

Idle>Off - DCD is On except when the unit is receiving an idle, OOS, or OOF
code or an LOS.

Force On - DCD is on all the time regardless of any unit condition.

Far RTS - This option adds tracking of the far end’s RTS lead to the existing
Idle>Off capability. DCD is On except when the unit is receiving an OOS, OOF
code or an LOS. It is also Off when the far-end unit’s RTS is inactive.

For tracking to occur, set the unit’s Mode to TXP-I or TXP-II and RTS to Normal.

RTS

Request To Send is an input to the unit from the DTE. Clear To Send is an output
from the unit to the DTE. When set to Normal, the unit reacts to RTS from the
DTE. When RTS is On, the unit transmits data normally and turns CTS to On
