Clock Source (Clk Source); Line Buildout (Lbo); Rx Sensitivity (Rx Gain); Channel Bandwidth (Channel Rate) - ADTRAN TSU IQ+ User Manual

Clock Source (CLK SOURCE)

Select the clock source to be derived from the network, from the
unit's internal clock, or from clock recovered from either the DTE
(V.35) or
clock source for transmission. Clocking necessary for receiving data
is recovered from incoming data. This option is most commonly set
to F
Choices: I

Line Buildout (LBO)

Select the line buildout for the network interface. In A
the TSU IQ+ sets the LBO based on the strength of the receive
signal. Options: A

Rx Sensitivity (RX GAIN)

Select the desired receiver sensitivity setting. The factory default is
N
setting should be used only in applications where the N
setting is not sufficient. If the receive signal strength is less than
30 dB, choose E

Channel Bandwidth (CHANNEL RATE)

Set the channel bandwidth for 56 or 64

Transmit PRM

Enabling performance report messages (PRM) allows the TSU IQ+
to send messages across the facility data link (FDL) per ANSI
T1.403. The terminating device at the telco may use this
information for management of the T1 loop.
The TSU IQ+ supports PRM messages per AT&T Pub 54016 which
is a poll/response type protocol. Because of this poll/response
nature, the transmit PRM option does not disable the TSU IQ+ from
processing or responding to 54016-type messages.
