vbr-nrt command

In this configuration example (from a CISCO887VA) will the the outbound traffic be restricted to 228K?

                  

interface ATM0
no ip address
no atm ilmi-keepalive
pvc 0/38
  vbr-nrt 288 288
  encapsulation aal5mux ppp dialer
  dialer pool-member 1

In this case the line is clocked upstream at 1200Kbps:

RTR#sh atm int atm 0
Interface ATM0:
AAL enabled:  AAL5,, Maximum VCs: 4, Current VCCs: 1

VCIs per VPI: 1024,
Max. Datagram Size: 1658
PLIM Type: ADSL - 1200Kbps Upstream, DMT, TX clocking: LINE
2915278 input, 7233878 output, 53305627 IN fast, 49814550 OUT fastVBR-NRT : 288
Avail bw = 912
Config. is ACTIVE

Thanks in advance

Yes.  Keep in mind, ATM (within the cloud) can have a cap on the bandwidth used by the PVC lower than the physical hand-off.

Also if this is an ADSL, your upstream bandwidth is often less than downstream bandwidth, and even downstream might be less than physical handoff's bandwidth.
