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

.
