Format
Ñ

V.35)
Select

operation. You can select
RS-449
and
EIA-530
by using different cables.
Clock
Ñ+SCT
,
-SCT
, or
SCTE
(DefaultÑ
+SCTE)
For
DTE
timing, select
SCT
, a unipolar clock generated by the
DCE
.
You can invert the clock
(-SCT)
or not
(+SCT)
.
Use
SCT
inversion
(-SCT)
and
SCTE
to correct delays in clocking due
to cable length.
When the data port is a
DCE
, select any of the three options.
When he data port is a
DTE
, you must select
SCTE
.
Allocating Timeslots
The DL600E
1.984 M
bps data rate is divided into
31 DS0
timeslots with
a default allocation of all
31
slots allocated to data port
1
.
You must allocate timeslots for the local and remote unit in
Menu-6 Timeslot ConÞguration
according to your speciÞc needs and
requirements.
Allocate by Port
Ñdisplays allocated timeslots for one data port at a time
only.
Network Timeslot Map
Ñdisplays the entire timeslot conÞguration.
The default factory allocation appears in
Allocate by Port
as follows:
Two Allocation Methods
Use one of two methods to allocate timeslots :
Contiguous
(default) or
Manual
. Select the allocation method in
Allocation Type
.
Contiguous
ÑAllocates timeslots in a contiguous order.
Manual
ÑAllocates timeslots in an arbitrary random order. This method
decreases the likelihood of unauthorized access using in-line taps.
The example in Figure
3-4
shows the timeslots for the local DL600E
single data port allocated in a random order. For the remote DL600E
unit, slots 1 through 18 are allocated to data port 1 and slots 19 through
31 to data port 2.
