DS 616 

INSTALLATION 

TECHNICAL MANUAL 

PART 2   JUNE  2002 

 

2.4 

 

Failure to provide an adequate ground may cause a safety hazard, confusing trouble 
symptoms or even circuit card failure. 
 

WARNING

: Unplug the power cord from the AC outlet before attempting to connect 

the ground. Hazardous voltage may cause death or injury. Observe extreme caution 
when working with AC power. Remove champ connectors from trunk cards. 

 
What the above paragraphs mean is when conventional analog telephone circuits are 
connected to the DS 616 system, under fault conditions (i.e., the tip and/or ring 
conductor is crossed with a power line, or the circuit is affected by lightning during a 
storm), it is possible for hazardous potentials to appear across the tip and ring wiring 
coming into the DS 616 cabinet(s) from the outside plant (i.e., overhead cables, buried 
cables, cable head pedestal). These circuits are provided with both primary and 
secondary protection circuitry which will attempt to drain off these high voltages and 
currents to earth ground. Obviously, it is important to have a good source of ground 
connected to the DS 616 system to drain this energy off. Also, certain metallic analog 
circuits (e.g., E & M trunks) require a current flow to earth ground to accommodate 
normal operating conditions and/or to resolve fault conditions. Again, a good earth 
ground source is required by the DS 616 system. 

 

The DS 616 system has two ground reference points. One point is via the green wire in 
the power cord connected to the AC power outlet. This ground connection is provided 
to meet local electrical codes when the AC ground is required to be common with the 
earth ground. However, this can be disconnected either intentionally or unintentionally. 
Consequently, a more permanent ground connection is required by connecting a high 
current/voltage capacity ground wire which is bonded to ground at the electric service 
power entrance or via some other method approved by the National Electrical Code to 
the DS 616 system ground lug. This is a more secure ground connection, which can 
only be disconnected intentionally. These precautions are taken for safety reasons to 
protect personnel working on the DS 616 system and also for operational reasons to 
accommodate ground return and/or ground-referenced analog telephone circuits, 
which require this solid earth ground connection for normal functioning. 

2.5 MDF CABLING 

(Figure 2–2)

 

All connections to the DS 616 system are made by way of a customer-provided main 
distribution frame (MDF). The KSU is connected to the MDF using one 25 pair, female 
amphenol-type cable and a 4-pair modular plug (RJ-45) plus cable (for connection of 
the Single Line Telephones). These cables can be routed into the KSU cabinet from 
below. 
 
Use one pair twisted jumper wire to cross-connect stations or lines to their associated 
port.
