PORT MENU
Use this menu to select and configure the parameters associated with the V.35 port.
TEL NUM
Sets the telephone number to be dialed to send alarm traps. The string can be up to 20
characters in length and is terminated with a semicolon (;) as the last character. A
colon (:) character is used to represent a pause in the dial string.
For example, for number 9:5551212; dial 9, pause momentarily and then dial
5551212. This pause could be necessary to access an outside line, such as a PBX.
When editing a specific character, the arrows are used to scroll from 0 to 9, then colon
(:) and semicolon (;). The new telephone number is entered into the TSU LT only after
typing the semicolon and pressing
E
NTER
.
Choices: 20 digits (
0-9
,
:
, and
;
)
The
ALARM > TEL NUM
menu only accepts the typed digits after pressing
E
NTER
.
RATE 56/64
Sets the base rate of the interface. The actual data rate depends on the number of
DS0s assigned to the Nx port. The DTE data rate versus the number of DS0s appears
in Appendix B,
Choices: 56K, 64K
CHANNELS
Sets the unit to use
A
LTERNATE
or
C
ONTIGUOUS
channels in the T1 data stream. If
more than 12 channels are used, then
C
ONTIGUOUS
must be used. Otherwise,
A
LTERNATE
channels may be used to meet pulse density requirements (this is only
necessary for Nx 64 without B8ZS). If other than a private network, the carrier must
be notified of this choice.
Choices: ALT (alternate), CONT (contiguous)
DTE TX CLK
Controls the clock used by the TSU LT to accept the transmit (TX) data from the
DTE. Most applications will allow for this to be set to
I
NTERNAL
. If the interface
cable is long (causing a phase shift in the data) the clock can be selected as
I
NT
-I
NV
(Internal/Inverted - the factory default setting). This switches the phase of the clock
which should compensate for a long cable.
The
A
UTO
setting allows the TSU LT to automatically detect the delay from the DTE
device to the TSU LT and set the proper phase of the clock. This feature
automatically selects between the
I
NTERNAL
and
I
NT
-I
NV
settings. If the DTE
provides a clock with TX data, the clock selection is set to
E
XTERNAL
. The TSU LT
depends on an externally supplied clock to accept the TX data.
Choices: INT-INV, INTERNAL, EXTERNAL, AUTO
