Conﬁguration Actions

1. Set the Device Name, up to 20 characters.

2. Set the Scrambler option. When Enabled, this option allows for

the DL3100 to ÒscrambleÓ user data to prevent errors on pattern

sensitive Þber equipment along the DS3 transmission path. Both

the local and remote DL3100s must be set the same. If you are

unsure, set both units for Scrambler Enabled.

3. Set the T3 (DS3) Framing Format which the carrier recommends:

C-bit or M13. If you are unsure, select C-Bit Parity. Both the

local and remote DL3100Õs must be set the same.

4. Set the Line Build Out (LBO): > or < 225 feet. LBO selects the

distance between the DL3100 T3 (DS3) interface and the carrier

demarcation point.

5. Set the Applications Data Link coding: NRZ or NRZI.

Applications Data Link sets the T3 Data Link coding. Both the

local and remote DL3100Õs must be set the same. If you are unsure,

set both to NRZI.
