Quick Set-Up

Figure 2-2 SCC 2020 Configuration Menu
The factory default values for the SCC 2020 are shown. The unit is
in CSU mode (DIU bus =
NONE NONE NONE NONE) and the network interface (shown on
the right at the top) is set for ESF framing and AMI line code.
The DSX-1 Equipment interface, shown at top left, is set for SF (D4)
framing and AMI line code. For this quick set-up the Equipment
interface is not being used, as it would be in CSU mode or Drop and
Insert mode. Because this example will use all 24 timeslots for data
purposes on a DIU 2130 module, Mux mode is required.
1. Type “A” and press E NTER , the prompt for bus selection
appears: DSU Bus (1)NONE (2)A (3)B (4)C (5)B,D&I EQ (6)A,D&I DSU Bus (1)NONE (2)A (3)B (4)C (5)B,D&I EQ (6)A,D&I DSU Bus (1)NONE (2)A (3)B (4)C (5)B,D&I EQ (6)A,D&I DSU Bus (1)NONE (2)A (3)B (4)C (5)B,D&I EQ (6)A,D&I
NET > NET > NET > NET > select “2” to use Data Bus A. This means that the CSU
and the DIU 2130 will use Data Bus A in the shelf to pass data
back and forth. The CSU is now in Mux mode. The EQPT LED
changes from red to green.
2. Type “F” and press E NTER , the prompt for line format appears:
Line Format(eq,net) 1(AMI,AMI) 2(AMI,B8ZS) 3(B8ZS,AMI) Line Format(eq,net) 1(AMI,AMI) 2(AMI,B8ZS) 3(B8ZS,AMI) Line Format(eq,net) 1(AMI,AMI) 2(AMI,B8ZS) 3(B8ZS,AMI) Line Format(eq,net) 1(AMI,AMI) 2(AMI,B8ZS) 3(B8ZS,AMI)
4(B8ZS,B8ZS) > 4(B8ZS,B8ZS) > 4(B8ZS,B8ZS) > 4(B8ZS,B8ZS) > select “4” for B8ZS (since the Equipment side
interface is not used, selection 2 would also work).
3. The default value for the density enforcement selection is not
correct for a B8ZS T1. Use the “Z” command and select “1” to
change it to NONE. B8ZS was developed to eliminate the need
for density enforcement.
4. For this example, a Network Service Provider (the phone
company) is providing a timing signal with a Digital Access
and Cross-connect System (DACS). This is usually the case
where an inter-exchange carrier (long distance company) is
