Clock Wire-Wrap Strip (P1)
A single wire-wrap strip is provided on the Total Access 850 backplane for connection to an external bits
clock. The external bits clock may be used to provide master timing for the Total Access 850 system.
Customer Connection (P2)
One 50-pin female amphenol connector (P2) provides the interconnect wiring for the access modules located
in slots 1 through 6 of the chassis. This connector is usually terminated with a punch-down block for premises
wiring or connected directly to a cross-connect or main distribution frame. Figure 7 details the connector
pinout.
