Lucent Technologies 7820-0802-003 manual Configuring the T3 physical link, Admin read t3 1 2

Configuring T3 Cards

Enabling a line

admin> read t3 {1 12 0} admin> set name = T3 Trunk

admin> write

T3/{ shelf-1 slot-12 0 } written admin> dir T3

17 04/17/1997 19:00:02 { shelf-1 slot-12 0 } "T3 Trunk"

For T3 lines, the Line Status window displays the first eight characters of the name if one has been assigned. For example:

"T3 Trunk" 1/15/00 LA la la la la la la la

If the name is longer than eight characters, the last character displayed is a plus sign (+).

Enabling a line

By default each DS3 line is disabled. When the DS3 interface is disabled, it transmits the DS3 Idle Signal to the far end.

To enable a T3 line, read its profile to make it the working profile, then set the Line-Interface subprofile’s Enabled parameter to Yes, as in the following example:

admin> read t3 {1 2 1}

T3/{ shelf-1 slot-2 1 } read

admin> set enabled = yes

admin> write

T3/{ shelf-1 slot-2 1 } written

Configuring the T3 physical link

You must specify a frame type and the length of the lines that connect the TAOS unit T3 slot card to the DSX-3 cross-connect. The line length must reflect the longest line length you expect to encounter in your installation. For a direct connection, double the value.

To configure the T3 card’s physical link, read its profile into the edit buffer, and enter the following commands:

admin> set frame-type = [m13c-bit-parity] admin> set line-length = [0-225226-450]

admin> write

Configuring clocking

For DS1 transmission, the T3 slot card uses the same system-wide PLL synchronous clock source used by the eight-port T1 cards. Any of the T3 card’s T1 lines can serve as the clock source for the TAOS unit system.

(For information about specifying a clock source, see “Configuring clocking” on page 7-17.)
