Switch S4 – Prescription Gain
S4 provides up to 1.5dB of gain in increments of 0.1dB to accommodate various input and output TLPs. To obtain
the correct operating levels, select switches S4–1 through S4–4 (0.1, 0.2, 0.4, and 0.8dB) in proper combination
to adjust the RCV path and switches S4–5 through S4–8 (0.1, 0.2, 0.4, and 0.8dB) in proper combination to ad-
just the XMT path.
7.4
Switch S5 – Prescription Gain
S5 provides up to 31dB of gain in increments of 1dB to accommodate various input and output office TLPs. To
obtain the correct operating levels, select switches S5–1 through S5–5 (1, 2, 4, 8, and 16dB) in proper combina-
tion with switches S4–1 through S4–4 to adjust the RCV path and switches S5–6 through S5–10 (1, 2, 4, 8, and
16dB) in proper combination with switches S4–5 through S4–8 to adjust the XMT path. A total of 32.5dB of gain is
provided to each path when all the switches of S4 and S5 are ON.
7.5
Push-On Jumper Option M1/M2/M3 (M-Lead Conditioning)
To arrange a busy condition to the far-end terminal when the NORM/BUSY switch is in the BUSY position, place
option M in the M2 position for E&M and in the M1 position for PLR. Connecting M to the M3 position disables the
busy function to the far-end by operation of the NORM/BUSY switch and accommodates testing functions.
7.6
Push-On Jumper Option N1/N2 (M2-Lead Conditioning) – 3652–62 Only
To condition the M2-lead for normal E2M2 operation, place option N in the N2 position. To perform tests on the
M2-lead, place option N in the N1 position. This will disconnect the office M2-lead and send a busy condition to
the far-end.
7.7
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. To condition the E-lead to go busy during an alarm condition, place option
P in the P2 position. To condition the E-lead to go idle during an alarm condition, place option P in the P3 position.
Push-on jumper option W (3652–62 only) conditions the E2-lead and is optioned similar to option P.
7.8
Screw Option Y (3652–68 Only) Auxiliary Trunk Processing
Screw option Y determines the state of an auxiliary set of contacts between pins 2 and 6 (1-lead and 2-lead, re-
spectively) during trunk processing. To provide a balanced (floating) contact closure between the 1-lead and
2-lead, open option Y. To provide a switched ground output on the 1-lead and a ground on the 2-lead, close option
Y.
7.9
Push-On Jumper Option Z1/Z2/Z3 (Types I, II, III or PLR Signaling Interface)
To condition the channel unit for an E&M Type I or Type III signaling interface, place option Z to Z2. To condition
the channel unit for an E&M Type II signaling interface, place option Z to Z3. To condition the channel unit for
PLR signaling in tandem mode, place option Z to Z1.
7.10
Screw Option ZC and FC (E-Lead/E2-Lead Conditioning)
Option ZC determines the idle condition of the M-lead in tandem mode. For an open on the M-lead (Type II), open
ZC. For a ground on the M-lead (Types 1 and III), close ZC. Option FC (3652–62 only) determines the idle condi-
tion of the E2-lead and is optioned similar to option ZC. For normal mode operation, open options ZC and FC.
