1
If the Committed Information Rate is set to
0
and the Excess Burst Size is set to a value
greater than
0
, the DE (Discard Eligibility) bit will be turned on in all received (
In
) and/
or transmitted (
Out
) frames.
2
CIR = Committed Information Rate. (See first parameter in table.)
3
Set
Outgoing DLCI Priority
to
4
for all Voice DLCIs (DLCIs over which Voice packets
will be sent).
4
Applicable only on the initiating node. (See explanation.) If configuring a DLCI that will
be backed up, you must leave this value at
0
until you have configured a backup group.
Then re-enter Port Configuration on this RLP/port/DLCI and specify the desired group.
A value of
0
means that the DLCI will not be backed up; therefore, set the Group to
0
if
the DLCI will be a backup.
5
Specify
N
for the initiating backup DLCI and
Y
for the remote backup DLCI.
6
Displayed only if
Backup G roup Number
is a value other than
0
.
7
Valid only if the remote node is an FRX6000 or FRM.
8
If set to
65535
, switchback will not occur unless the backup fails.
Port Type
specifies the protocol the port will support. Selecting this parameter will display a list
of all serial protocols loaded in the SmartSwitch.
Physical Port Interface
must be configured as follows. For reference, port locations are shown on
page 6-1
.
●
Port 0 is always
RS-232
.
●
Port 1 is
RS-232
or
DSU
, depending on whether the optional CSU/DSU card is
installed.
●
Ports 2 and 3 are determined by the attached cables:
RS-232
,
V.35
, or
RS-449
.
