Connecting Lines
A fully expanded DSX-40 can connect up to 8 analog loop-start lines with built-in Caller ID. The basic Main
Equipment Cabinet provides 4 lines. By adding a 4-Port Line Card you can connect the system to 8 lines.
See Installing Expansion Cards (page 25) for more.
To connect lines:
1. Using Figure 10: Punch Down for Lines (page 31) as a guide, plug the installation cable plugs into the
appropriate jacks on the Main Equipment Cabinet.
2. For each line, run one pair cross-connect wire between the line block and the CPE (customer side) of the
telco’s RJ21X.
3. Install bridging clips as required.
