Access Manager 2000 User Manual

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.
