Step 4 For V.35 and X.21 interfaces, check the mode (DCE or DTE) of each relevant port by using the
dspfrport command. (For T1 and E1 lines, the mode is not applicable.) On an FRI-X.25 or FRI-V.35
back card, a jumper board near each connector determines the mode of the port. See the “Port Mode
Selection for V.35 and X.21” section on page 9-5.
Step 5 For optional Y-cable redundancy, configure the two slots for redundancy by using the addyred
command. For V.35 and X.21 interfaces, go to Step 8.
Step 6 For T1, E1, and J1 interfaces, bring up the line using the upln command.
Step 7 For T1, E1, and J1 interfaces, configure the line using the cnfln command.
Step 8 For T1, E1, and J1 interfaces, add the logical FR port using the addport command.
Step 9 Activate the port using the upport command.
Step 10 Configure the port for speed, clocking, LMI type, and so on, by using the cnfport command.
Alternatively, you can keep the default parameters.
Step 11 Determine which FR class number to use when you add connections to a port. To see the parameters that
a class specifies, use the dspcls command. To modify parameters in a class, use the cnfcls.
Step 12 Add connections to the port by using the addcon command. Enter the slot number and specify a DLCI
for each end of the connection.
Step 13 For an individual connection, you can configure bandwidth parameters or enable ForeSight (if
purchased) by using the cnffrcon.
Step 14 Optionally, you can set the channel priority by using the cnfchpri command. Normally, the
system-default priority is adequate.
