Install equipment-room hardware for G600

Sneak-current protectors must have a maximum rating of 350 mA and a minimum voltage rating of 600V, 
or as required by local regulations. The following devices protect the system from over-voltages:

Analog trunks use the 507B sneak protector or equivalent. Over-voltage protection is normally 
provided by the local telephone company.

Analog voice terminals use one of the following types of combined over-voltage and sneak-
current protection, or equivalent:

— Carbon block with heat coil for UL code 4B1C

— Gas tube with heat coil for UL code 4B1E-W

— Solid state with heat coil for UL code 4C1S

DCP and ISDN-BRI terminals use the solid state 4C3S-75 with heat coil protector, or equivalent.

DS1/T1 circuits require isolation from exposed facilities. This isolation may be provided by a 
channel-service unit (CSU) (T1), or other equipment that provides equivalent protection.

Sneak-current protection is required between the incoming RJ21X or RJ2GX network interface and the 
system for both trunk and off-premises circuit packs. The model 507B sneak-current fuse panel, or 
equivalent, is recommended for sneak-current protection. See
