Line Type and Length

The line type and line length options enable the user to configure the
MultiDSU to match the characteristics of the T1 line.
The default selection is CSU (0db) or DSX-1 (0-133ft). CSU is a long
haul line type that allows the DSX-1 signal to be transmitted up to 6000
ft at Line Build Out (LBO) options of 0 dB, -7.5 dB, -15 dB, or -22.5 dB.
If the line type is DSX-1, you can select any of 5 available ranges of line
length up to 655 ft, maximum. DSX-1 is a short haul line type often
referred to as "cross-connect," especially within Telco central offices.

DS0 Speed/DS0 Allocation Menu

This menu enables you to configure the DS0 speed and (for Fractional
T1 only) the DS0 allocation.
DS0 Speed/DS0 Allocation
Enter Selection (-(previous), q(uit), <1>): _

DS0 Speed

The default is 64Kbps clear channel communications; however, you can
also select 56Kbps.
Each of the 24 DS0 signals in a full T1 is 64 kbps for a total bandwidth of
1.536 Mbps. When 8 kbps is added to the 24 DS0 time slots, the
resulting data rate is 1.544 Mbps, which is referred to as the DS1 signal.

DS0 Allocation

This option enables you to configure the MultiDSU to match the band-
width used. For full T1, use the default, "1-24." For Fractional T1 (FT1)
enter the range(s) of DS0s available on your T1 line; e.g., "1-10" or "1-
10,20-24." All the DS0s are assigned to the Data port of the MultiDSU.
