Primary data rate in kbps on Port 1.
48 to
—
Sets port primary speed to one of 11 operating rates.
1.2 kbps
Disab
—
Sets port primary speed to 0 bps.
Choosing a primary speed for Port 1 and pressing Next brings up the speed selection menu for Port 2.
Continue selecting port speeds until the primary speeds for all six ports have been chosen. (The default for
Ports 2—6 is Disab.)

Option Verification: For all ports, the DSU verifies that the sum of the individual port speeds do not exceed
48 kbps. (The line speed, set via the DSU’s Rate(Kbps) configuration option, must be set to 56 kbps. Refer
to Table 6-1,
DSU Configuration Options
.)

Next Disab Prt1 Prt2 Prt3 Prt4 Prt5 Prt6 Prev
Underspeed Port. Selects which port is run slightly underspeed to allow for in-band framing and in-band
secondary channel transport, if used. If more than one port is active, including the in-band secondary
channel transport and the sum of the speeds (not included in the in-band secondary channel transport)
equals the primary aggregate speed, then one synchronous port must run underspeed. The number of bits
per second used for in-band framing is 10. The in-band secondary channel transport speed is set in 2nd
Chan(bps) and, if used, includes the 10 bps in-band framing. A port used for asynchronous operation may
not be set for underspeed. (This configuration option is ignored in Bridge mode.)
NOTE: Underspeed cannot be used with 4.4, 9.2, and 18.8 kbps data rates.
Disab
—
No port runs underspeed during primary operation.
Prt1 to —
Selected port runs underspeed during primary operation. (Ports 3—6 do not appear when
Prt6
a 2-port MCMP/Flex is installed.)
Option Verification: The DSU verifies that an underspeed channel is selected if the sum of the port speeds
equals the primary aggregate speed.
1
Port speeds in DSD and FEP port-sharing groups are only counted once per group when calculating used
bandwidth.
* Only appears when MUX Funct is set to MCMP. Refer to
Port Speed Configuration Options for DSU with TDM
(Table 6-14) if MUX Funct is set to TDM.
