INSTALLER CONNECTIONS
Electrical connections for the channel unit are made by wire-wrapping leads onto the associated 50-pin connec-
tors located on the backplane of the 360/363 D4 terminal. When installing a 3652–62/68 channel unit into a non-
connectorized 360/363 D4 terminal (00-suffixed), make the required connections as shown in Table 3. On con-
nectorized 360/363 D4 terminals (360–10, –11, etc.), connections are made via 25-pair female connectors
(CINCH 222–22–50–023 or equivalent) to the appropriate 25-pair male connectors of the 360/363 D4 terminal.
Refer to Section 360–000–200 for the wiring diagrams of the female connectors with respect to the 360/363 D4
terminal being utilized.

OPTIONS
The 3652–62 and 3652–68 channel units are equipped with push-on jumpers, DIP switches, and screw options
that are used to condition the module for proper application and operation. Refer to Figure 8 and Table 4 for op-
tion locations and a brief summary of the option conditioning requirements.
Note:
When opening a screw option, rotate the screw counterclockwise two full turns to ensure that the connec-
tion is open. When closing a screw option, rotate the screw clockwise until it seats. When selecting the
push-on jumper options, push the jumper over the appropriate pins within that option grouping to obtain
the desired operation.
7.1
Switch S1 – NORM/BUSY
Place the NORM/BUSY switch to the NORM position to condition the channel unit for normal operations. Place
the NORM/BUSY switch to the BUSY position when testing or aligning the channel unit.
7.2
Switch S2 – NORM/REV and Switch S3 – NORM/TANDEM
For E&M signaling, place switches S2 and S3 to NORM. For PLR signaling, place switch S2 to REV and switch
S3 to TANDEM. Switch S2 reverses the E&M leads to E on pin 45 (ring of the E&M jacks) and M to pin 4 (tip of
the E&M jacks) to accommodate central office wiring in the tandem mode of operation. S2 also interfaces the use
of standard test sets when in the tandem mode. Note that S2 does not affect the E2 and M2 leads, and that S3
does not affect the VF levels. With the ER feature, nominal PLR levels are within the adjustment range capability
of S4 and S5 (Prescription Gain Controls.)
