6-4 CHAPTER 6: MANUAL SETUP
Currently, the SVC capability is disabled in the OfficeCon nect Remote 812.
ATM Category of Service parameters specify characteristics (sometimes called
traffic shaping parameters) for data transmitted from the OfficeConnect Remote
812 to the remote site. They have no effect on data transmitted from the remote
site to the OfficeConnect Remote 812.
The ATM VC information and Category of Service parameters are entered into the
profile using the set vc <vc name> atm comman d. For PVCs, you must enter VPI
and VCI information for each profile.
set vc name <vc name> atm vci <vci value> vpi <vpi value>
You should have been provided with Category Of Service parameters.
UBR - Unspecified Bit Rate; No limit has been sp ecified for the upstream data
flow.
CBR - Constant Bit Rate; A constant rate has been specified for the upstream
data flow.
The cell rate transmission parameters are used to specify upstr eam tra nsmission
rates for the particular Category of Service.
PCR - the Peak Cell Rate is the maximum number of cells/second transmitted
over this connection. The Peak Cell Rat e is optional for UBR and required for
VBR and CBR.
SCR - the Sustainable Cell Rate, in cells/second. This is the maximum average
rate. The SCR is required for VBR.
BT - the Burst Tolerance or Maximum Burst Size, in cell/second. The is the
maximum number of cells that can be sent at the peak ra te. T he BT is required
for VBR.
To configure the profile for UBR, use:
set vc <vc name> atm category_of_service unspecifed pcr <cell rate >
To configure the profile for VBR:
set vc <vc name> atm category_of_service variable pcr <cell rate> scr < cell
rate > bt < cell rate >
To configure the profile for CBR:
set vc <vc name> atm category_of_service constant pcr < cell rate >
where the pcr parameter is used for the constant bit rate that is desired instead of
as the peak cell rate.
If no traffic shaping parameters have been provided you should choose UBR w ith a
PCR value of 0. The OfficeConnect Rem ote 812 will attempt to use all of the
upstream bandwidth when transmitting data to the remote site.
IP Routing The OfficeConnect Remote 812 can be con figured as an IP Router to forward
packets between the local LAN interface and one or more Remote Sites.
