Access Manager 2000 User Manual 5 -101
Port 1 = Channels1 and 2
Port 2 = Channel 3
Port 3 = Channel 4
Port 4 = Channel 5.
DS0A Use this mode to transmit subrate data on data Port 1. The
rate on this port can be 0.3, 0.6, 1.2, 2.4, 4.8, or 9.6 kbps.
After selecting DS0A, also set the data rate individually
for data Port 1. Ports 2 through 5 are not available if the
DS0A mode is selected. In this mode, the data is repeated
enough times to fill the 48 kbps payload.
19.2 + FEC Use this mode to transmit data on a 19.2 kbps port with
forward error correction (FEC). In this mode, Port 1 is
used for transmission with error correction according to
AT&T Publication 54075. Ports 2 through 5 are not used
in this mode.
19.2 + 19.2 + S Use this mode to transmit 19.2 kbps on
EQP Ports 1 and 2 and subrate data of 9.6 kbps or less on
Port 3. In this mode, Ports 4 and 5 are not available. When
this mode is chosen, the rates for Ports 1 and 2 are
automatically entered in the
Baud Rate column of the
DIU 2140 Configuration Menu and you must specify the
desired subrate for Port 3 as described in “Baud Rate” on
page 5-101. The DS0B channels are assigned as follows:
Port 1 = Channels 1 and 2
Port 2 = Channels 3 and 4
Port 3 = Channel 5
Ports 4 and 5 are not used.
Baud Rate
After choosing the data transmission mode option above, specify the data
rate for each data port as required. The rates for some of the ports may
already be entered, depending on which mode was chosen above.
Generally, you must specify the rate whenever a data port transmits
subrate data at 9.6 kbps or less.
Asynchronous
Set this option to YES for each data port operating in the asynchronous
transmission mode, or set it to NO if synchronous transmission is used.
