Issue 6) 4-Wire E&M with PLR and ER (4W E&M/PLR) Channel Units. These channel units are used in the Charles Industries 360/363 D4 Digital Carrier Terminal. The 3652–62 is shown in Figure 1. Table 1 lists the 4W E&M/PLR channel units and those of the former issue which they replace. -
Page 3: Part 2. Inspection
Equipment Identification Charles Industries’ equipment is identified by a model and issue number imprinted on the front panel or located elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue number is advanced by 1 and imprinted on subsequent units manufactured. - Page 4 Section 365–262–205 Figure 3.

Section 365–262–205 stream via the XDATA lead, indicating a busy condition on the channel circuit. An on-hook condition (open) causes a logic 0 state to be transmitted with the outgoing bit stream and indicates a channel idle condition. On the 3652–62, the M2-LEAD DETECTOR will cause a logic 1 to be transmitted on the B highway for a ground con- dition on the M2-lead, and a logic 0 to be transmitted for an open on the M2-lead. -
Page 11: Part 6. Installer Connections
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. - Page 12 Push-On Jumper Option P1/P2/P3 (E-Lead Conditioning) and W1/W2/W3 (E2-Lead Conditioning 3652-62 Only) Trunk Processing During a Carrier Failure To condition the E-lead (M-lead for tandem mode) to go idle then busy 2.5 seconds later during an alarm condi- tion, place option P in the P1 position.
