DIU 2130 Configuration
Verilink 3-9
RTS
Request To Send—a control lead presented by the DTE (Data Terminal
Equipment) to indicate that it has data that it would like to transmit. The
Verilink DIU 2130 is DCE (Data Communications Equipment) which expects to
receive RTS as an input from the DTE (Data Terminal Equipment). Typically if
RTS is not asserted by the DTE then no user data is conveyed end to end.
If the DTE does not assert RTS this option allows the DIU 2130 to behave as it
would if RTS were asserted by the DTE. The DIU 2130 will output CTS (Clear To
Send) as a “high” or asserted value when RTS is on for that port.
This feature can be set independently for port 1 and/or port 2.
The user types "RTS" and gets this response:
force rts handshake port(s) (1) 1 (2) 2 (3) both (4) none >
The display as shown in our example reflects RTS forced on port 1 and not on
port 2.
CTS
Clear To Send—a control lead presented by the DCE (Data Communications
Equipment) to indicate that the DTE may now transmit. CTS is the logical result
of RTS being on and no major alarm condition being present. The Verilink DIU
2130 is DCE (Data Communications Equipment) which expects to receive RTS as
an input from the DTE (Data Terminal Equipment). Typically if RTS is not
asserted by the DTE then no user data is conveyed end to end.
If the DTE does not assert RTS this option allows the DIU 2130 to behave as it
would if RTS were asserted by the DTE. The DIU 2130 will output CTS (Clear To
Send) as a “high” or asserted value when CTS is on for that port.
This feature can be set independently for port 1 and/or port 2.
The user types "CTS" and gets this response:
force cts handshake port(s) (1) 1 (2) 2 (3) both (4) none >
The display shown reflects CTS forced on port 1 and not on port 2.
DCD
Data Carrier Detect—a control lead presented by the DCE (Data
Communications Equipment) to indicate that it is receiving a valid, framed
signal. The Verilink DIU 2130 is DCE (Data Communications Equipment) which
outputs DCD.
This option allows the DIU 2130 to output DCD as a HIGH or asserted value at
all times for that port.
This feature can be set independently for port 1 and/or port 2.
The user types "DCD" and gets this response:
force dcd handshake port(s) (1) 1 (2) 2 (3) both (4) none >
The display shown reflects DCD forced on port 1 and not on port 2.
Mode For each port, the Mode may be set to either 56K or 64K. This selection
determines the bandwidth usage per DS0 (a DS0 is the same thing as a timeslot
and is also sometimes called a channel). To set the mode for port 1, type M1;
To set the mode for port 2, type M2.
If the T1 circuit being used is AMI the mode must be 56K.
If the T1 circuit being used is B8ZS the mode may be either 56K or 64K, as the
user or application may require.
