Chapter 5 Config Menu TSU LT 220V User Manual

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 220V

only after typing the semicolon and pressing

ENTER.

Choices: 20 digits (

0-9, :, and ;)

The ALARM > TEL NUM menu only accepts the typed digits after pressing ENTER.

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, DTE Data Rate Chart, on page 53.

Choices: 56K, 64K

CHANNELS

Sets the unit to use ALTERNATE or CONTIGUOUS channels in the T1 data stream. If

more than 12 channels are used, then

CONTIGUOUS must be used. Otherwise,

ALTERNATE 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 220V to accept the transmit (TX) data from

the DTE. Most applications will allow for this to be set to

INTERNAL. If the interface

cable is long (causing a phase shift in the data) the clock can be selected as

INT-INV

(Internal/Inverted - the factory default setting). This switches the phase of the clock,

which should compensate for a long cable.

The

AUTO setting allows the TSU LT 220V to automatically detect the delay from

the DTE device to the TSU LT 220V and set the proper phase of the clock. This

feature automatically selects between the

INTERNAL and INT-INV settings. If the DTE

provides a clock with TX data, the clock selection is set to

EXTERNAL. The TSU LT

220V depends on an externally supplied clock to accept the TX data.

Choices: INT-INV, INTERNAL, EXTERNAL, AUTO
