Configuration 39
DTE Port
Parameters
The DTE Port Configuration screen (Figure 4-8) allows configuring either or both
DTE ports. The options for Port A are always available. The options for Port B are
only available if the DTE mode is set to TDM. It is important that the DTE ports
are configured identically at opposite ends of a link. If Port A of one unit is
configured for asynchronous 19.2 kbps, then Port A at the far end must also be
configured for asynchronous 19.2 kbps. Neglecting to do this inhibits the ability to
pass DTE traffic from end-to-end. It is also possible that data intended for one port
(Port A) can come out the opposite port (Port B) at the far end. This data
swapping is a side effect of the rate swapping feature and only occurs at DTE rates
of 31.2 kbps (TXP-I) and 38.4 kbps (TXP-II) when the units are improperly
configured.
Figure 4-8 DTE Port Parameters Screen
Element
This field allows reviewing and modifying the DTE port parameter values for the
near-end or far-end unit. The screen position on either unit is independent. If the
unit is in the DTE Port Parameters screen on the near-end unit, toggling the
Element to Far displays the last screen accessed on the far-end unit such as the
Main Menu, Utilities, Configuration, or Summary screen.
DTE Mode
The 41TDM DTE interfaces can operate in two general modes: TDM and
Non-TDM. In the Non-TDM mode, DTE interface B is disabled and DTE interface
A can run at higher speeds. In TDM mode, both DTE interfaces are active, and are
multiplexed together into the single DDS network path. Select TXP-I or TXP-II
mode on the Network Parameters screen to enable TDM.
Type
The choices for Port A and Port B are V.35, RS-232D, and EIA-530.
