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
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
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.
