Note:
Zetron recommends using stranded wire for the radio station interface, as it provides
superior durability. The wire should be at least 14 gauge. It is also useful to have
different colored wrap to easily identify each signal lead.
66-Type Punchdown Block Installation
If the telco connections were made using a 66-type punchdown block, then the lower half of the
block (pins #13-25 and 38-50) provides the leads for the radio station interface. Refer to Table 9
for descriptions of each pin on the Model 640 RJ21 connector.
Follow the steps below to interface the radio station equipment to the optional punchdown block:
q
1.
Power-down the paging terminal.
