Key

Description

Range

Note

N

Name. User defined alpha-numeric

label for circuit.

12 character maximum.

Used as an entry key for

future edits of this circuit.

P

Priority. Sets order in which circuits are

routed. Highest priority circuits are

routed first.

Low, normal, high, critical.

Default = normal.

Important when a network

includes ISDN or other

backup ability.

T

Type. Circuit type sets basic function of

this circuit. Except where some

method of alternative routing or a

switched facility like ISDN is available,

most circuits will be permanent type.

Permanent, switched,

primary, dial backup,

backup.

Selection of circuit type may

cause additional option

parameters to appear. See

further details in the section

“Circuit Types”

below

.

M

Mode. Bandwidth usage per timeslot,

select 56K or 64K for most cases.

Actual data rate becomes 56K or 64K

multiplied by the number of DS0s

selected, except subrate ports.

56K or 64K except for

subrate DIU ports.

On DIU2131 port 2 rates

available are: 2.4K through

64K: on DIU 2140 rates

available are 2.4K through

19.2K.

SP

Source Port. Port from which circuit

originates. A specific port on an

application module currently installed

in a slot of a shelf in the node.

Shelf number/slot number

separated by a comma

(1,7), then a port of the

card per list presented.

Source port may be a

network port or a data port.

Circuits must have one

network port.

DP

Destination port: Port at which circuit

terminates. A specific port on an

application module currently installed

in a slot of a shelf in the node.

Shelf number/slot number

separated by a comma

(1,8) then a port of the

card per list presented.

Destination port may be a

network port or a data port.

If a circuit uses ISDN, it must

be the Destination port.

SM

Source Mapping. Timeslots to use at

the Source Port. For T1/E1 ports these

are level zero (DS0) timeslots at 56K or

64K each. For T3 ports these are level

1 (DS1) timeslots - at T1 rate each.

Enter the timeslots with

comma separators or a

range with a hyphen

between first and last. For

example: 1,2,3,4 or 1-4.

One timeslot only for

circuits terminating in

subrate DIU ports. 1-24 for

T1 ports. 1-30 for E1 ports.

1-28 for T3 ports.

DM

Destination Mapping. Timeslots to use

at the Destination Port. For T1/E1

ports these are level zero (DS0)

timeslots at 56K or 64K each. For T3

ports these are level 1 (DS1) timeslots -

at T1 rate each.

Enter the timeslots with

comma separators or a

range with a hyphen

between first and last. For

example: 1,2,3,4 or 1-4.

One timeslot only for

circuits terminating in

subrate DIU ports. 1-24 for

T1 ports. 1-30 for E1 ports.

1-28 for T3 ports.

U

Bus. Selects which, if any, backplane

bus will be used to transfer data from

one application module to another for

this circuit.

For circuits with source

and destination ports in

different modules, choose

A,B,C or Auto. Auto allows

the Circuit Manager to

select the best bus to use.

For circuits with source and

destination ports on the

same module no bus is

required. For more details

on bus selection see the

section

“Backplane Bus”

.

S

Setup. Used to start a fully configured

circuit. All parameters above should be

entered first before setup is invoked.

When Setup command is

issued, Circuit Manager

will attempt to route and

initialize the circuit.

After a brief pause, the

menu is redisplayed with the

status of the circuit shown

on same line as bus

selection.

X

Exit. Return to Circuit Manager Menu

above.

If the Add Circuit Menu is

exited before completing a

circuit, when the Add

Circuit Menu is re-entered,

the incomplete circuit will

be displayed.

Should a circuit fail to

become active, check the

configuration of the

application module(s) and

verify ports used are

configured as active ports.
