2.2.5.1
Facility 4-Pin Wirewrap Connectors
Eight, 4-pin wirewrap connectors are available for Facility con-
nections on the OmniPak
t
8. These connectors are located
under the Facility Compartment cover near the top of the PCB.
The connectors are labelled CKT1 through 8, one for each cir-
cuit. Each connector has pins for T", R", T1", and R1".
2.2.5.2
Facility 50-Pin/25-Pair Connectors
Two 50-pin/25-pair Telco connectors for Facility connections are
also located under the Facility Compartment cover (Paragraph
2.1.1) at the top of the mounting. The left connector, P1, is la-
belled FACILITY RCV IN. The right connector, P2, is for
FACILITY XMT OUT.
2.2.6
Customer Connections
For ease of use, three types of connectors are available for Cus-
tomer connections: either wirewrap pins, RJ48C/S jacks, or one
25-pair RJ48H-type connector, as described hereunder.
2.2.6.1
Customer 4-Pin Wirewrap Connectors
On each OmniPak
t
8, in a separate internal compartment un-
der the assembly’s module area, are eight, 4-pin, wirewrap
connectors for customer connections. These connectors are lo-
cated under a Customer Wirewrap Pin cover (Paragraph 2.1.3)
at the bottom of the mounting. The connectors are labelled
CKT1 through 8, one for each circuit. Each connector has pins
for CT", CR", CT1", and CR1". A cut-out near the bottom,
right side of the assembly provides Customer wirewrap pin wir-
ing access through a strain-relief gasket or grommet.
2.2.6.2
RJ48C/S Jacks (Exterior Access)
Under the module compartment of the OmniPak
t
8 are eight
RJ48C/S jacks for customer connections. The jacks are labelled
CKT 1 (corresponds with slot/circuit 1) through CKT 8 (corre-
sponds with slot/circuit 8). A 2-position switch, labelled S" at
the top and C" at the bottom, is provided immediately to the
right of each RJ jack, which options the jack for either RJ48S or
RJ48C functionality.
2.2.6.3
RJ48H 50-pin/25-pair Connector (Exterior Access)
A third method for making customer connections is through an
RJ48H-type, 25-pair connector, located under the module
compartment near the bottom of the assembly, labelled CUS-
TOMER INTERFACE".
