CONFIGURATION
Configures the ATLAS Quad USSI Module.
» Name
Write security: 3; Read security: 5
Allows you to enter a descriptive alpha-numeric name for each port.
» Clk (+/-)
Write security: 3; Read security: 5
(TX Clock Polarity) Controls the clock used by the ATLAS Quad USSI Mod-
ule to accept the transmit (TX) data from the DTE. This is usually set to
Nor-
mal
. If the interface cable is long, causing a phase shift in the data, the clock
can be set to
Inverted
. This setting switches the phase of the clock, which
should compensate for a long cable.
» Data
Write security: 3; Read security: 5
(Data Format) Inverts DTE data. This inversion can be useful when operat-
ing with a high-level data link control (HDLC) protocol (often used as a
means to ensure 1s density). Select either
Normal
or
Inverted
.
» CTS
Write security: 3; Read security: 5
(Clear to Send) Controls characteristics of CTS (see Table 3-1). Choose from
Normal
or
Forced On
.
» DCD
Write security: 3; Read security: 5
(Data Carrier Detect) Indicates to the DTE when a valid signal is being
received at the Network Interface (see Table 3-1). Choose from
Normal
or
Forced On
.
» DSR
Write security: 3; Read security: 5
(Data Set Ready) Indicates to the DTE when the DCE is turned
On
and
ready for operation (see Table 3-1). Choose from
Normal
or
Forced On
.
» DTR
Write security: 3; Read security: 5
(Data Terminal Ready) Determines whether the ATLAS_800 treats a connec-
tion as permanent (
DTR=Ignore
) or temporary, connecting only when DTR
is active, (
DTR=Connect On DTR
). Select either
Ignore
or
Connect on
DTR
.
» 0 Inh
Write security: 3; Read security: 5
(Zero Inhibit)
Instructs the ATLAS 800 to send 1s toward the network when
the port detects an uninterrupted string of 0s transmitted for more than one
second.
» Inband
Write security: 3; Read security: 5
Creates an 8 kbps management channel by robbing a bit from the first DS0
assigned to the port. This channel can manage remote ADTRAN products.
» Send Leads
Write security: 3; Read security: 5
Sends the state of the DTE leads to the remote unit whenever any DTE lead
changes state. See the online help menus for more information.
