TSU LT User Manual
Sets the starting channel for the T1 stream. This setting must be consistent with the
START CHAN
carrier if using a public network.
Choices: 01 through 24
# OF CHAN
Sets the number of DS0s (channels) to be used. The corresponding DTE rate will be
this number times 56K or 64K, depending on the setting of
Choices: 01 through 24
Controls the inversion of DTE data. This inversion can be useful when operating
DATA
with an HDLC protocol. Often used as a means to ensure ones (1s) density. TSU LTs
on both ends must have identical option settings.
Choices: NORMAL, INVERT
CTS
Clear To Send - signal sent from the receiving station to the transmitting station that
indicates it is ready to accept data.
Choices: NORMAL (see Table 5-2 on page 46), FORCE ON
Data Carrier Detect - Indicates to the DTE when a valid signal is being received at
DCD
the Network Interface.
Choices: NORMAL (see Table 5-2 on page 46), FORCE ON
DSR
Data Set Ready - Indicates to the DTE when the DCE is turned
operations.
Choices: NORMAL (see Table 5-2 on page 46), FORCE ON.
Inband Configuration Channel - Use to enable/disable an 8-kbps remote
INBAND
configuration channel (see Figure 5-7 on page 46). When this option is set to
first DS0 occupied operates in 56K mode and the DTE clock rate is reduced by
8 kbps. The TSU LT uses this 8-kbps channel to send and receive configuration data
across a T1 span. As shown in Figure 5-7, this feature allows the PC connected to
the Chain In port on TSU LT A to monitor and configure both TSU LT A and B.
This feature is useful when FDL connectivity is not available across the T1 span.The
8-kbps channel is only taken out of the first DS0. If two 64K DS0s are mapped, the
DTE rate would be 120 kbps instead of 128 kbps.
This menu option can also be set to
when commands are sent from T-Watch PRO to the remote unit (TSU LT B in
Figure 5-7). If no T-Watch PRO activity is detected for 10 minutes, the Inband
Channel is deactivated.
